Description

Controlled release formulations for agrochemicals
Abstract
The present invention relates to encapsulated active compounds (actives / active ingredients / AI) produced by different methods with minimized / eliminated negative effects on the plant (phytotoxicity) resulting in enhanced biological compatibility while efficacy against pests is maintained.
Background of the invention
Active ingredients can be formulated in various ways, wherein the properties of the actives and the process of formulation may raise problems with regard to processability, stability, usability and efficacy of the formulations as well as negative effects of the active ingredients itself on the plant.
Moreover, some formulations are advantageous over others for ecological and / or economical reasons.
As pointed out above, some useful acitives show unwanted effects on plants when applied, like phytotoxicity leading to severe damage of the plant, leave necrosis (also denoted halo effect), late emergence (stunting), reduced yield, etc.
For some actives the severity of the side effect is almost independent of the applied concentration, i.e. despite of a significantly decreased active concentration the side effect is seen at unchanged severity. For example, a pronounced phytotoxicity (a.k.a. Halo ) can be observed for Fluopyram treated soybean seeds in early stages of emergence, even if there is no more nematicidal or fungicidal effect at this decreased concentration. A similar negative side effect is seen for a number of dicotoleydons, including but not limited to soy beans, tomatos, cucumbers, peppers / capsicums when e.g. fluopyram is spray applied to soil. Further examples include phytotoxic effects of herbicides, including but not limited to e.g. diflufenican and/or isoxaflutole spray applied to soil for treatement of soy beans and com.
To overcome these side-effects, it is genereally known to controll the release of the actives, thus lower concentrations might lead to less unwanted effects. However, alongside the controlled release of active, often a reduction or total loss of efficacy against the pest is being observed.
The challenge to manufacture a controlled release formulation is even more demanding for sprayable application forms, i.e. particle size restrictions apply, and very high active concentrations are required (in contrast to state of the art pharmaceutical controlled release applications). Alongside the physical and biological properties of such controlled release formulations economically aspects play an important role. The three herein described approaches differ signifantly in their biological, physical and ecomical footprint. Economical refers to the number of involved process steps and consequently the cost of production. Table 0 shows general classification of the technologies and deary indicates the fine balance between achievable product properties and economical considerations. Even though Approach A will not provide the best materials with respect to leaf damage reduction (phytotoxicity) it may be favoured because of industrialization. Approach A was found to provide reasonable and significant improvement with respect to phytotoxicity.

The afore described boundaries require a controlled release par excellence, to manufacture agrochemical sprayable controlled release formulations, that achieve a significant reduction or elimination of negative side effects such as phytotoxicity while keeping the efficacy while fulfilling economical requirements.
Polymeric materials encapsulating compounds are described in W02010039865A2. W02007091494A1 describe pesticide preparations containing pesticide-containing resin with controlled release. W0200007443Aldiscloses contolled release granules with an active containing hull on a solid carrier. US4285720A discribes water immiscible organic substances which are encapsulated with polyurea. A process for spray coat pharmaceutical particles is described in US5632102A, however, not disclosing coating of very fine particles.
Further EP1325775A1 and US201 1228628A generally described a jet bed apparatus that allows coating of fine particles, although not for controlled release appliactions. Description of the invention
Therefore, there is a need for improved formulations which are safe to handle, which retain the efficacy and consistency of use in a challenging agricultural environment, i.e. soil. In particular, significant reduction, or in some embodiments full elimination, of phytotoxicity side effects was surpringsly achieved on crops that are showing a very high sensitivity for phytotoxicity for respective pesticides.
In particular there is need for encapsulated active ingredients, e.g. for use said formulations according to the inventions.
The controlled release formulations disclosed herein will be applicable to Seeds, Soil, Leaf by Spray/Coating/ Drench/Granular/ Infurrow/Nursery box/Paddy field, and common field applications. Further, the controlled release formulation may improve physical, chemical, biological compatibility (phytotoxicity) or stability or longevity for relevant actives or minimize / eliminate negative effects on the plant in afore mentioned applications.
In a preferred embodiment the reduction of phytotoxicity of the active ingredient is more than 50 %, more preferred more than 80 %, and most preferred more than 90 % percent, while efficacy against pests is maintained. Maintained as used herein means the efficacy is at least at 50% or more of the not encapsulated reference.
The tested references refer to the same formulations comprising the same ingredients as the formulation according to the invention, except that the active is not encapsulated (in the reference).
These problems are solved by the embodiments for encapsulation of the present invention as described below as well as formulations containing said encapsulated actives and their use for agrochemical applications.
"Pests" as used in the present invention refers to insects, nematodes, fungi, bacteria, viruses and weeds.
"Actives" as used in the present invention include fungicides, herbicides, insecticides, nematicides, host defence inducers, biological agents and bactericides.
In one embodiment actives means fungicides. In another embodiment actives means nematicides.
In another embodiment actives means herbicides.
In another embodiment actives means insecticides.
In another embodiment actives means host defence inducers. In another embodiment actives means biological agents.
In another embodiment actives means bactericides.
"Seed Treatment" as used in the present invention means applying at least one active ingredient directly or in form of a coating directly on a seed before bringing said seed onto the field. For clarification sake, foliar applications, in furrow application, nursery box applications and soil applications are not seed treatment applications.
"Encapsulated active ingredients" as used herein refers to actives which are encapsulated according to methods A, B or C, respectively, described below.
The terms "active compounds", "actives", "active ingredients", "agrochemical compounds" and "AIs" can be used herein interchangeably.
The term“CR” in the present invention, if not otherwise defined, means“controlled release”.
The folloing term-pairs can be used herein interchangeably: FLU/Fluopyram; DFF/Diflufenican; IFT/Isoxaflutole.
If not otherwise defined or with further parameter extended in the present invention, particle size is measured according to CIPAC (CIPAC = Collaborative International Pesticides Analytical Council; www.cipac.org) method MT 187 determined as D50 respectively D90 = acitive ingredient particle size (laser diffraction 50%, respectively 90% of overall volume particles The mean particle size denotes the D50 value.
In the formulations of the present invention at least one active is encapsulated, while additional actives may be present non-encapsulated in the formulation.
The present invention further provides formulations, and application forms prepared from them, as crop protection agents and/or pesticidal agents, such as drench, drip and spray liquors, comprising at least one of the active compounds of the invention. The application forms may comprise further crop protection agents and/or pesticidal agents, and/or activity-enhancing adjuvants such as penetrants, and/or spreaders and/or retention promoters and/or humectants and/or fertilizers and or other commonly used adjuvants, for example.
Examples of typical formulations include emulsifiable concentrates (EC), emulsions in water (EW), suspension concentrates (SC, SE, FS, OD), water-dispersible granules (WG), granules (GR) and capsule concentrates (CS); these and other possible types of formulation are described, for example, by Crop Life International and in Pesticide Specifications, Manual on development and use of FAO and WHO specifications for pesticides, FAO Plant Production and Protection Papers - 173, prepared by the FAO/WHO Joint Meeting on Pesticide Specifications, 2004, ISBN: 9251048576. The formulations may comprise active agrochemical compounds other than one or more active compounds of the invention. The formulations or application forms in question preferably comprise auxiliaries, such as extenders, solvents, spontaneity promoters, carriers, emulsifiers, dispersants, frost protectants, biocides, thickeners and/or other auxiliaries, such as adjuvants, for example. An adjuvant in this context is a component which enhances the biological effect of the formulation, without the component itself having a biological effect. Examples of adjuvants are agents which promote the retention, spreading, attachment to the leaf surface, or penetration.
These formulations are produced in a known manner, for example by mixing the active compounds with auxiliaries such as, for example, extenders, solvents and/or solid carriers and/or further auxiliaries, such as, for example, surfactants. The formulations are prepared either in suitable plants or else before or during the application.
Suitable for use as auxiliaries are substances which are suitable for imparting to the formulation of the active compound or the application forms prepared from these formulations (such as, e.g., usable crop protection agents, such as spray liquors or seed dressings) particular properties such as certain physical, technical and/or biological properties.
Suitable extenders are, for example, water, polar and nonpolar organic chemical liquids, for example from the classes of the aromatic and non-aromatic hydrocarbons (such as paraffins, alkylbenzenes, alkylnaphthalenes, chlorobenzenes), the alcohols and polyols (which, if appropriate, may also be substituted, etherified and/or esterified), the ketones (such as acetone, cyclohexanone), esters (including fats and oils) and (poly)cthcrs, the unsubstituted and substituted amines, amides, lactams (such as N-alkylpyrrolidones) and lactones, the sulphones and sulphoxides (such as dimethyl sulphoxide).
If the extender used is water, it is also possible to employ, for example, organic solvents as auxiliary solvents. Essentially, suitable liquid solvents are: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols such as butanol or glycol and also their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide and dimethyl sulphoxide, and also water.
In principle it is possible to use all suitable solvents. Suitable solvents are, for example, aromatic hydrocarbons, such as xylene, toluene or alkylnaphthalenes, for example, chlorinated aromatic or aliphatic hydrocarbons, such as chlorobenzene, chloroethylene or methylene chloride, for example, aliphatic hydrocarbons, such as cyclohexane, for example, paraffins, petroleum fractions, mineral and vegetable oils, alcohols, such as methanol, ethanol, isopropanol, butanol or glycol, for example, and also their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, for example, strongly polar solvents, such as dimethyl sulphoxide, and water. All suitable carriers may in principle be used. Suitable carriers are in particular: for example, ammonium salts and ground natural minerals such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as finely divided silica, alumina and natural or synthetic silicates, resins, waxes and/or solid fertilizers. Mixtures of such carriers may likewise be used. Carriers suitable for granules include the following: for example, crushed and fractionated natural minerals such as calcite, marble, pumice, sepiolite, dolomite, and also synthetic granules of inorganic and organic meals, and also granules of organic material such as sawdust, paper, coconut shells, maize cobs and tobacco stalks.
Liquefied gaseous extenders or solvents may also be used. Particularly suitable are those extenders or carriers which at standard temperature and under standard pressure are gaseous, examples being aerosol propellants, such as halogenated hydrocarbons, and also butane, propane, nitrogen and carbon dioxide.
Examples of emulsifiers and/or foam-formers, dispersants or wetting agents having ionic or nonionic properties, or mixtures of these surface-active substances, are salts of polyacrylic acid, salts of lignosulphonic acid, salts of phenolsulphonic acid or naphthalenesulphonic acid, polycondensates of ethylene oxide with fatty alcohols or with fatty acids or with fatty amines, with substituted phenols (preferably alkylphenols or arylphenols), salts of sulphosuccinic esters, taurine derivatives (preferably alkyltaurates), phosphoric esters of polyethoxylated alcohols or phenols, fatty acid esters of polyols, and derivatives of the compounds containing sulphates, sulphonates and phosphates, examples being alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates, protein hydrolysates, lignin-sulphite waste liquors and methylcellulose. The presence of a surface-active substance is advantageous if one of the active compounds and/or one of the inert carriers is not soluble in water and if application takes place in water.
Suitable surfactants or dispersing aids, for example are all substances of this type which can customarily be employed in agrochemical agents such as non-ionic or anionic surfactants. Preferred non-ionic surfactants are polyethylene glycol ethers of branched or linear alcohols, reaction products of fatty acids or fatty acid alcohols with ethylene oxide and/or propylene oxide, furthermore polyvinyl alcohol, polyoxyalkylenamine derivatives, polyvinylpyrrolidone, copolymers of polyvinyl alcohol and polyvinylpyrrolidone, and copolymers of (meth)acrylic acid and (meth)acrylic acid esters, acetylene diol ethoxylates, furthermore branched or linear alkyl ethoxylates and alkylaryl ethoxylates, where polyethylene oxide-sorbitan fatty acid esters may be mentioned by way of example. Out of the examples mentioned above selected classes can be optionally phosphate, sulphonated or sulphated and neutralized with bases.
Possible anionic surfactants are all substances of this type which can customarily be employed in agrochemical agents. Alkali metal, alkaline earth metal and ammonium salts of alkylsulphonic or alkylphospohric acids as well as alkylarylsulphonic or alkylarylphosphoric acids are preferred. A further preferred group of anionic surfactants or dispersing aids are alkali metal, alkaline earth metal and ammonium salts of polystyrenesulphonic acids, salts of polyvinylsulphonic acids, salts of alkylnaphthalene sulphonic acids, salts of naphthalene-sulphonic acid-formaldehyde condensation products, salts of condensation products of naphthalenesulphonic acid, phenolsulphonic acid and formaldehyde and salts of lignosulphonic acid, as well as polycarboxylic acids, sodium and potassium salts. Preferred non-ionic surfactants are for example:
Tristyrylphenol ethoxylates comprising an average of 5-60 EO units; castor oil ethoxylates comprising an average of 5-40 EO units (e.g. Berol® range, Emulsogen® EL range); fatty alcohol ethoxylates comprising branched or linear alcohols with 8-18 carbon atoms and an average of 2-30 EO units; block-copolymer of polyethylene oxide and polyhydroxystearic acid; ethoxylated polymethacrylate graft copolymers; polyvinylpyrrolidone based polymers; polyvinylacetate based polymers; ethoxylated diacetylene-diols (e.g. Surfynol® 4xx-range); alkyl ether citrate surfactants (e.g. Adsee® CE range, Akzo Nobel); alkyl polysaccharides/polyglycosides (e.g. Agnique® PG8107, PG8105, Atplus® 438, AL-2559, AL-2575); ethoxylated mono- or diesters of glycerine comprising fatty acids with 8 - 18 carbon atoms and an average of 10 - 40 EO units (e.g. Crovol® range); block-copolymer of polyethylene oxide and polybutylene oxide. organomodified polysiloxanes, e.g. BreakThru® OE444, BreakThru® S240, Silwet® L77, Silwet® 408, Silwet® 806.
Preferred anionic surfactants and polymers are for example:

More preferred surfactants are ethoxylated polymethacrylate graft copolymers, polycarboxylic acids, sodium and potassium salts, tristyrylphenol ethoxylate sulfate and ammonium and potassium salts thereof, naphthalene sulphonate formaldehyde condensate, sodium salt and ethoxylated diacetylene-diols. In Table 1 tradenames for commonly known surfactants are shown:

Further auxiliaries that may be present in the formulations and in the application forms derived from them include colorants such as inorganic pigments, examples being iron oxide, titanium oxide, Prussian Blue, and organic dyes, such as alizarin dyes, azo dyes and metal phthalocyanine dyes, and nutrients and trace nutrients, such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
Stabilizers, such as low-temperature stabilizers, preservatives, antioxidants, light stabilizers or other agents which improve chemical and/or physical stability may also be present. Additionally present may be foam- formers or defoamers.
Furthermore, the formulations and application forms derived from them may also comprise, as additional auxiliaries, stickers such as carboxymethylcellulose, natural and synthetic polymers in powder, granule or latex form, such as gum arabic, polyvinyl alcohol, polyvinyl acetate, and also natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids. Further possible auxiliaries include mineral and vegetable oils.
There may possibly be further auxiliaries present in the formulations and the application forms derived from them. Examples of such additives include fragrances, protective colloids, binders, adhesives, thickeners, thixotropic substances, penetrants, retention promoters, stabilizers, sequestrants, complexing agents, humectants and spreaders. Generally speaking, the active compounds may be combined with any solid or liquid additive commonly used for formulation purposes.
Suitable retention promoters include all those substances which reduce the dynamic surface tension, such as dioctyl sulphosuccinate, or increase the viscoelasticity, such as hydroxypropylguar polymers, for example. Suitable penetrants in the present context include all those substances which are typically used in order to enhance the penetration of active agrochemical compounds into plants. Penetrants in this context are defined in that, from the (generally aqueous) application liquor and/or from the spray coating, they are able to penetrate the cuticle of the plant and thereby increase the mobility of the active compounds in the cuticle. This property can be determined using the method described in the literature (Baur et al., 1997, Pesticide Science 51, 131-152). Examples include alcohol alkoxylates such as coconut fatty ethoxy late (10) or isotridecyl ethoxylate (12), fatty acid esters such as rapeseed or soybean oil methyl esters, fatty amine alkoxylates such as tallowamine ethoxylate (15), or ammonium and/or phosphonium salts such as ammonium sulphate or diammonium hydrogen phosphate, for example.
In a preferred embodiment, the formulation with the encapsulated active comprises: a) at least one encapsulated active ingredient, b) a liquid phase, c) optionally one or more emulsifier / dispersant, d) optionally one or more carriers, e) optionally one or more surfactants, f) optionally further non-encapsuled active ingredients, g) optionally further adjuvants selected from the group of extenders, stickers, penetrants, retention promoters, colourants and dyes, stabilizers, humectants and spreaders.
In a more preferred embodiment, the formulation with the encapsulated active comprises: a) at least one encapsulated active ingredient, b) a liquid phase, c) optionally one or more emulsifier / dispersant, d) optionally one or more carriers, e) one or more surfactants, e.g. Geropon T36 and / or Morwet D 425, f) optionally further non-encapsuled active ingredients, g) optionally further adjuvants selected from the group of extenders, stickers, penetrants, retention promoters, colourants and dyes, stabilizers, humectants and spreaders.
In one embodiment the formulation consists of a) and b) which add up to 100%.
A suitable liquid phase for the formulation may be water (SC), Oils and/or organic solvents (OD).
Preferably the liquid phase is water.
Suitable cross linkers according to the present invention are typically those used to connect polymer chains. Crosslinkers therefore typically adjust the physico-chemical properties of polymer, for example reducing solubility, swellability, solvent and/or active permeability; increasing melting point and/or glass transition temperature. Any of the properties before may be changed through crosslinking to an extend that e.g. a soluble polymer becomes fully insoluble or thermoplastic polymer becomes thermosetting. Crosslinking is typically achieved chemically, either by complexation or kovalent linkage. Common examples for cross linkers are aldehydes such as formaldehyde, glutaraldehyde, terephthalaldehyde, low molecular weight epoxides such as epichlorohydrin, activated esters such as NHS esters, imidoesters, maleimides, carbodiimide, other crosslinkers may include Pyridyldithiol, hydrazine, bi- or higher functional isocyanates or photo induced drosslinkers.
The capsules (encapsulated material) prepared according to methods A to C comprise between 1% and 99.9% by weight of active compound or, with particular preference, between 20% and 95% by weight of active compound, more preferably between 25% and 95% by weight of active compound, and most preferred between 50% and 95% by weight of active compound, based on the weight of the whole capsule (active + shell).
Before encapsulation the active compound has a particle size of preferably dso < 50 pm, more prefered dso < 20 pm, even more prefered dso < 10 pm, and most preferred dso < 5 pm.
Preferably, before encapsulation the active compound has a particle size of dso > 0.1 pm,
The particle size of the produced capsules is preferably between dso = 1-200 pm (micrometer), more preferred between dso = 1-50 pm (micrometer). For foliar applications the particle size is preferably between dso = 1-20 pm (micrometer).
The formulations preferably comprise between 0.1% and 70% by weight of active compound or, with particular preference, between 1% and 65% by weight of active compound, more preferably between 5% and 60% by weight of active compound, and most preferred between 5% and 50% by weight of active compound, based on the weight of the formulation. The active compound content of the application forms for herbicides (including but not limited to Diflufenican & Isoxaflutole) prepared from the formulations may vary within wide ranges. The active compound concentration of the application forms may be situated typically between 0.00001% and 50% by weight of active compound, preferably between 0.001% and 5% by weight, based on the weight of the application form. Application takes place in a customary manner adapted to the application forms.
The active compound content of the application forms for nematicides/fungicides (including but not limited to Fluopyram) prepared from the formulations may vary within wide ranges. The active compound concentration of the application forms may be situated typically between 0.00001% and 50% by weight of active compound, preferably between 0.001% and 10% by weight, based on the weight of the application form. Application takes place in a customary manner adapted to the application forms.

Biological control agents:
As used herein,’’biological control” is defined as control of a pathogen and/or insect and/or an acarid and/or a nematode by the use of a second organism. Known mechanisms of biological control include enteric bacteria that control root rot by out-competing fungi for space on the surface of the root. Bacterial toxins, such as antibiotics, have been used to control pathogens. The toxin can be isolated and applied directly to the plant or the bacterial species may be administered so it produces the toxin in situ.
Biological control agents include in particular bacteria, fungi or yeasts, protozoa, viruses, entomopathogenic nematodes, inoculants and botanicals and/or mutants of them having all identifying characteristics of the respective strain, and/or a metabolite produced by the respective strain that exhibits activity against insects, mites, nematodes and/or phytopathogens.
According to the invention, biological control agents which are summarized under the term "bacteria" include spore-forming, root-colonizing bacteria, or bacteria and their metabolites useful as biological insecticdes, -nematicdes, miticides, or -fungicide or soil amendments improving plant health and growth.
Biological control agents according to the invention, in combination with good plant tolerance and favourable toxicity to warm-blooded animals and being tolerated well by the environment, are suitable for protecting plants and plant organs, for increasing harvest yields, for improving the quality of the harvested material and for controlling animal pests, in particular insects, arachnids, helminths, nematodes and molluscs, which are encountered in agriculture, in horticulture, in animal husbandry, in forests, in gardens and leisure facilities, in the protection of stored products and of materials, and in the hygiene sector. They can be preferably employed as plant protection agents. They are active against normally sensitive and resistant species and against all or some stages of development. Biological control agents include in particular bacteria, fungi or yeasts, protozoa, viruses, entomopathogenic nematodes, products produced by microorganisms including proteins or secondary metabolites and botanical, especially botanical extracts.
According to the invention, the biological control agent may be employed or used in any physiologic state such as active or dormant.

The encapsulated actives according to the present invention can be produced by three alternative processes, which are described in the following:
Methods
As far as not otherwise indicated in the present invention % refers to weight percent (wt.%).
Planting and Growth
For Seed treatment all soybean seeds were allowed to dry for 24 hr. prior to planting and were run alongside an untreated control (UTC) and a FLU FS 600 (48 w/w%, 0.075 mg/seed) treated sample for comparison.
Greenhouse evaluations were conducted using a pasteurized sandy loam soil consisting of less than 1% soil organic matter and a minimum of 20 reps for each treatment. Three planting options were utilized based on greenhouse space and experiment size 1) 60 cell trays 2) 30 cell trays and 6 in. stand alone pots. Prior to planting 6 in. pots were wet with 150 mL of water per pot, while 30 and 60 cell trays were irrigated for 10 s with an overhead water source. Subsequently, a 2 cm hole was created and 1 seed was planted per hole and covered with soil. Plants were grown for approximately 21 d in a temperature and day length regulated greenhouse. Water was uniformly supplied at regular intervals throughout the growth period. All trials demonstrated a germination rate of 90% or greater.
Cotyledons were harvested when the unifoliate leaves reached full development and analyzed for the halo effect. Specifically, cotyledons were removed and analyzed when unifoliate leaves are fully emerged for all samples and the first trifoliate leaves are present but not fully developed. The top of each cotyledon was scanned and analyzed using WinFolia software which measured total leaf area, healthy leaf area, and halo area. Differentiation between healthy and halo cotyledon area was determined by using color screening analysis, where darker regions signified halo area and green regions signified healthy leaf tissue. For seeds treated with formulations obtained according to process A to C a visual halo rating system was also employed which consisted of a rating system from 0 to 4. The criteria for each rating are outlined in
Figure 1 : Unifoliate leaves were analyzed for size using WinFolia software after the first trifoliate leaves were fully emerged.
Plant heights were typically measured at approximately 7 DAP (days after planting), which is when unifoliate leaves first emerge and begin to develop and at 14 DAP or when the first trifoliate has completely emerged.
Canopy analysis was performed at 7- 10 days after planting (DAP) to determine the impact of the treatment on stunting. Images were taken and analyzed using the app Canopeo which quantifies the canopy cover of green vegetation using images taken with a mobile device. Images were taken at the same distance from the samples and under similar light conditions.
Root Lesion Nematode (RLN) Bioassay was conducted 7 DAP soybean seeds were inoculated with 1000- 2000 RLN juveniles using a standard inoculation methodology. In brief, the soybean pots were wet 5 min prior to inoculation, then a 2 cm deep hole was created next to the stem of the soybean plant. Subsequently, a pipette was used to dispense 0.5-1.0 mL of inoculum into the hole. Next, the roots were removed from soil, cleaned of excess sand and soil, and briefly submerged in water. The roots where then blotted with a paper towel and cut into 1 to 2 cm pieces that were spread onto a baeman funnel (~ 2 g fresh weight/funnel). The funnels were covered with foil and allowed to sit for 3 d. The funnels were then drained and 30 mL of liquid was retained and the RLN count was determined from this sample.
Sudden Death Syndrome (SDS) Bioassay was conducted by preparing an inoculum by placing 800 g of wheat into beaker and covering with potato dextrose broth. The beaker was then autoclaved for 30 mins on 2 consecutive days. After 24-28 h post autoclave, 1 plate of Fusarium Virguliforme was added to each beaker and grown at room temperature. After 14 d the jars were grown out and desiccated.
Next a cone was stacked with 100 cc of soil, followed by ¼ plate of Fusarium Virguliforme inoculum. Two soybean seeds were placed on top and the cone was filled with 40 cc of soil. The seeds were grown under wet conditions and evaluated for SDS symptoms at the first trifoliate using a 0-6 scale, where 0 represents no symptoms and 6 represents a wilted or dead plant.
Biology tests in herbicide soil spray applications for controlled release formulations (general procedure)
Samples were supplied as aqueous suspensions and were applied at 50, 100, 200 g active per hectare. Briefly, seeds of grasses, weeds and agricultural crops were seeded in pots with 8 cm diameter in natural soil (slit- rich, non-sterile). Seeds were covered with 0.5 cm of soil and cultivated in a glasshouse (12-16 h light, temperature day 20-22°C, night 15-18°C). At the BBCH 00 state of growth of the seeds/plants the inventive formulation was applied using a water volume of 300 L/ha. After herbicide treatment all plants were cultivated further in the glasshouse as described above. Daily irrigation was set to 1.0- 1.5 liter per square meter. Efficacy of the treatment was visually assessed and graded after 14 days or 28 days after herbicide application. A grading of 0% reflects a healthy non-treated plant, i.e. the non-treated reference population and 100% represents full efficacy of the herbicide, i.e. a deceased plant. For reference the two commercial suspension concentrates Balance™ Pro (isoxaflutole without safener) and Brodal® (diflufenican) were chosen.
Particle sizes and zeta potentials for formulations obtained to process A were determined via laser diffraction (Malvern Mastersizer S) in aqueous solution; typical dilution 1 : 1000 of as synthesized formulation. Zeta potential of the dispersions was measured using a Malvern Zetasizer ZS90 in 1 mM KC1 as a function of pH; typical dilution 1 : 100 to 1: 1000 of as synthesized formulation. All other particle sizes were determined through laser diffraction using a Malvern mastersizer hydro 3000s. All samples were measured by dispersing in water and applying ultrasound for 300 sec prior to the measurement. Scattering Modell: Fraunhofer; analysis tool: universal
Active content of all formualtions according to process A was determined using a thermogravimetric analysis, fully evaporating the aqeous phase at 160°C and measureing the residual dry mass and calculating the active content based on the employed manufacturing ratio (dispersion concentrate vs polymer solution). The obtained dry mass was corrected for the fluopyram to stabilizer mass in the dispersion concentrate, i.e. 48% fluopyram and 3% inerts in the dispersion concentrate.
Release kinetics of the active into pure water were analyzed using a HPLC assay. The method can be used to either analyze the release from the formulated suspension or to evaluate release kinetics from a dry application mixture. The following process was used for determination of release from aqueous dispersions (CS, SC or FS type formulation). A LiChroCart Purosher Star PR-18e, 3.0 pm was used with an isocratic gradient: 50% 0.1% phosphoric acid and 50% acetonitrile.
For examination of aqueous dispersion type formulations, incl. CS / SC / FS, an aliquot of the formulation was placed in 1.0 L of purified water and shook on an orbital shaker at the lowest reasonable speed, i.e. 50-100 rpm. The added volume of the formulation was carefully chosen to ensure infinite sink conditions during release. Samples were withdrawn after 1 h and 24 hours, optionally for some samples after 5 & 300 min. In order foster full release for tightly encapsulated formulations, another 100 mL of acetonitrile were added to the mixture after 1 day, continuously shook at unchanged speed for another day, and followed by a last sample withdrawal after 48 hours. Prior to the actual HPLC-analysis, every sample taken was centrifuged to remove particulate (encapsulated) active from the supernatant. The clear supernatant was then submitted for F1PLC analysis. The latest data point (48 hours) was taken for normalization of the release to 100%.
When used for treated seeds, ca. 15 g of the treated seeds, were immersed in 500 mL water. Samples were withdrawn and treated as described above.
Controlled release was evident if the release profile was significantly lower than for a similarly formulated non- encapsulated sample, i.e. less than 50% release at a given point in time.
Encapsulation efficiency EE was determined using the release FLU concentration within the first f0 minutes, i.e. EE = 1 - [c(FLU-encapsulated,10 min) / c(FLU-reference, 10 min)].
Process A (Coating of Fluopyram using a microjet reactor process plus optional cross-linking)
According to process 1 - to obtain the encapsulated materials - the active is homogenized in water with surfactants and subseqently milled, preferably in a bead mill, to obtain a dispersion concentrate of the active.
In a second step the active containing suspension is mixed in a microjet reactor (cf. e.g. nanoSaar; http://www.nanosaar.de/nanosaarlahgmhh/) with a polymer solution to obtain a non-crosslinked encapsulation. More preferred mixing takes place at a pressure of 50-60 bar with jet velocities of - 100 m/S and a mixing time of 0.1 - 1.0 ms. Furthermore preferred pH of the either/or the dispersion concentrate and polymer solution is adjusted prior to high shear mixing in the microjet reactor according to the polymer used, for example, for polyvinylalcohol pH is preferably between 4 and 5 (measured with pH-glass electrode OPS11), while the pH for Chitosan is preferably between 11 and 12.
Optionally, in a third step the particles obtained in the steps above are crosslinked for stabilization and/or to control the release properties of the particles.
The so obtained encapsulation may not be fully tethered to the active surface but may contain loosely attached or unbound polymers or a highly swollen polymer gel. As a consequence the degree of control release, i.e. active release may change with the final application, i.e. drying of the formulation upon seed treatment. Likewise curing/aging/drying may significantly alter the release profile / rate.

The encapsulation method as well as the products and their properties are described in the examples below.
Example Process A The Materials used are defined in below. The production process itself was devided into: production of A.1 dispersion concentrate - A.2 encapsulation - A.3 crosslinking.
A.1 Production of the dispersion concentrate Fluopyram for A-l to A-107
3.388 kg Fluopyram are homogenized with 140 g Geropon T36, 70 g Morwet D 425 and 3.4 kg demineralized water. Subsequently the homogenzided mixture is milled in a beadmill under wet conditions containing glass beads with a diameter of 0.75 - 1 mm (Bachofen KDL 0.6L with Glasbeads, 80% capacity, peripheral speed 10 m/s, 3 passages, turnover 3.4 kg/h). Subsequently, a 40% active dispersion of Fluopyram slurry is prepared by dilution of a concentrated slurry (solid content: 48 % active, 3% inert stabilizer/surfactants) with DI water.
A.2 Production of the dispersion concentrate Isoxaflutole for A-l 08 to A-l 11
968 g Isoxaflutole are homogenized with 40 g Geropon T36, 20 g Morwet D 425, 1 g Silfoam SE 39 and 968 g demineralized water. Subsequently the homogenzided mixture is milled in a beadmill under wet conditions containing glass beads with a diameter of 0.75 - 1 mm (Bachofen KDL 0.6L with Glasbeads, 80% capacity, peripheral speed 10 m/s, 3 passages passages (repititions may be adjusted to yield required particle size), turnover 3.4 kg/h). Subsequently, pH was adjusted by additional citric acid to < 5.
A.3 Production of the dispersion concentrate Diflufenican for A-112 and A-113
968 g Diflufenican are homogenized with 40 g Geropon T36, 20 g Morwet D 425 and 968 g demineralized water. Subsequently the homogenzided mixture is milled in a beadmill under wet conditions containing glass beads with a diameter of 0.75 - 1 mm (Bachofen KDL 0.6L with Glasbeads, 80% capacity, peripheral speed 10 m/s, 3 passages (repititions may be adjusted to yield required particle size), turnover 3.4 kg/h).
A.2 Encapsulation
The active suspension produced as above and a solution of Chitosan (parent solution 0.5, 1.0, 1.5, 2.0 or 2.5 % w/w in water) (alternatively PVA (parent solution 3 or 12 % w/w in water)) are homogenized in a symmetric 200 pm microjet reactor, Nanosaar, under the following conditions (pressure 50 - 60 bar, jet velocity > 100 m/s, mixing time 0.1- 1.0 ms, pH as indicated in Table 2). Final polymer and AI concentrations are provided in cl. 4 and 5 of Table 2.
Briefly, the 40wt % aqueous dispersion comprising fluopyram dispersion having >90 wt% of particles smaller than 1 pm and an anionic dispersant was adjusted to pH = 13.5 by addition of 5M NaOH (alternatively pH = 4 for PVA-coating, adjusted with glacial acetic acid). This solution was processed against a chitosan solution set to pH = 4 (alternatively, pH = 6.7 for the PVA in DI water) in a MJR reactor. Flow rates of solutions were adjusted by pump rate to a mass ratio of about 1 (Chitosan coating solution) to 2 (Fluopyram slurry). Processing was conducted at room temperature in a symmetric MJR (200 pm ruby nozzles) reactor by impinging chitosan solution with fluopyram dispersion at a hydrodynamic pressure of 50 to 60 bar to yield chitosan coated fluopyram dispersion. For cross-linking 10 mol% of Glutaraldehyde (with respect to chitosan) can be added to the fluopyram dispersion prior to processing by MJR or in a separate post - processing step, details see below.
A.3 Crosslinking
Optionally crosslinker is added (0.5, 3.0, 10.0 or 20.0 mol% based on reactive groups of the polymer. Cross linker solutions were employed as obtained by the supplier and can either be added to the active dispersion prior to the coating process or added under stirring to the final formulation after coating via MJR. Typically the amount of cross-linker was added prior to the coating process. After MJR processing cross-linking was conducted for at least 12 h at room temperature at the resulting pH shown in Table 2. The cross-linking reaction was allowed react without any quenching, such as typically employed tris-buffer or ammonium chloride quenching.
Formaldehyde (FA) was used as 37% (w/w) in water and Glutaraldehyde (GA) in 25% (w/w) in water.
For aldehyde crosslinking pH, reaction temperature and reaction time was adjusted to control the release rate, cl. 10 Table 2.

Figure imgf000047_0002
Zeta potential measurements can be used to validate the successful coating process. The zeta potential of the non controlled-release coated fluopyram is highly negative within a broad pH range, i.e. at least between pH 3-10, cf. Table 4, indicating the high potential for adsorption of neutral or positively charged polymers. The strongly negative charge of -38 mV of the uncoated fluopyram dispersion, cf. Table 2: A- 107, becomes more positive upon PVA coating due to shielding, eventually reaching -8 mV and -12 mV for a non-cross-linked and crosslinked PVA, respectively (cf. Table 2 A-94 & A-95 ). Due to the highly positive charge of a protonated chitosan the zeta potential undergoes a full inversion of the charge finally reaching +59 mV upon coating (cf. Table 2, A-103).
Visual inspection:
All samples were inspected visually for either phase separation by sedimentation of particles or gelation. As opposed to sedimentation gelation was irreversible and these samples cannot be employed for spray type applications, examples for gelation are marked in Table 2. All samples in which phase separation was observed could easily be homogenized by shaking.
Seed treatments and biology tests for formulations obtained according to process A Samples were supplied as aqueous suspensions and were applied to soybean seeds at a rate of 0.075 mg/seed using 100-250 g of seeds in a small or medium sized Hege bowl seed treater, cf. Table 5.

Fluopyram biology tests in soil drench applications for formulations obtained according to process A
Samples were supplied as aqueous suspensions, cf. Table 2, and were applied at 8, 10, 20 mg a.i. per cucumber plant by applying 60mL soil drenches. Plant health (damage) was examined 3 / 4 / 5 / 7 / 10 and 14 days after application by visual inspection of leafs (% leaf area with chlorosis+necrosis) and shoot fresh weight measurement. Samples obtained according to process A were tested versus untreated control cucumber plants (UTC) and a non-controlled release fluopyram (Velum® SC400). The positive effect obtained from samples formulated according to process A applied on soil varies with the applied dose rate (dose response), and additionally, reflects the controlled release profiles, cf. Table 8 and Figure 2. Either early reduction of leaf damage (day 0 to 7) at high-dose application of 20 mg fluopyram/plant for samples A-33 and A-34, or, a up to 14 days lasting overall reduction of leaf damage at dose of 8 and 10 mg fluopyram/plant for samples A-41 and A-42 can be obtained.

Nematicidal efficacy of a selected sample obtained according to approach A and applied at 1 mg fluopyram per pot. Infestation using Meloidogyne incognita in tomato (Rentita) was done 1 , 7 and 14 days after drench treatment (active dispersed in 120 mL water) with the controlled release formulation. Outcome analysis was performed by means of visual inspection of root galling (given in percent). Analysis was carried out in triplicate. The controlled release formulation A-42 was found to have increasing efficacy over time which is a result of its controlled release formulation nature (cf. Figure 7).
Herbicide biology tests in soil spray applications for formulations obtained according to process A
Samples were supplied as aqueous suspensions, cf. Table 2, and were applied at 50, 100, 200 g active per hectare. Briefly, seeds of grasses, weeds and agricultural crop were seeded in pots with 8 cm diameter in natural soil (slit-rich, non-sterile). Seeds were covered with 0.5 cm of soil and cultivated in a glasshouse( 12- 16 h light, temperature day 20-22°C, night 15-18°C). At the BBCH 00 state of growth of the seeds/plants the inventive formulation was applied using a water volume of 300 L/ha. After herbicide treatment all plants were again cultivated in the glasshouse as described above. Daily irrigation was set to 1.0- 1.5 liter per square meter. Efficacy of the treatment was assessed by visual grading after 14 days or 28 days, whereas a grading of 0% reflects a healthy non-treated plant, in agreement with the non-treated reference population and 100% represents full efficacy of the herbicide, i.e. a deceased plant. For reference the two commercial products Balance™ Pro (isoxaflutole without safener) and Brodal® (diflufenican) were chosen.Controlled release formulations A- 108 & A- 109 of isoxaflutole were compared to the non-controlled release reference Balance™ Pro which contains no safener for treatment of maize plants, cf. Table 9. Independent of the application rate the efficacy profile against common grasses and weeds was comparable for all formulations in this study. However, at application rates of 50 g/ha and 100 g/ha an improved tolerability against the controlled release formulations A- 108 & A- 109 is evident. At higher application rates, i.e. 200 g/ha, the improved phytotoxicity profile of the controlled release formulation could not be observed. Table 9: Controlled release isoxaflutole herbicide applied on maize proves the superiority of the controlled release treatments,“plant damage” (percent).
Figure imgf000051_0001
Figure imgf000052_0001
As for the treatment of maize, application of controlled release isoxaflutole formulations on soja is superior to a non-controlled release reference, cf. Balance™ Pro Table 10. Controlled release formulations A-108 to A-l 11 of isoxaflutole were compared to the non-controlled relase reference Balance Pro. Independent of the application rate the efficacy profile against common grasses and weeds was comparable to the reference Brodal pro for tested formualtions A- 108 and A- 109 and somewhat reduced against avena fatua for A-l 10 and A- 11 1. Alongside the excellent application profile against weeds and grasses the formulations A- 108 to A-l 11 allowed for varying degrees in improved tolerability of the agricultural crop soya against the herbicidal formulation. Table 10: Controlled release isoxaflutole herbicide applied on maize proves the superiority of the controlled release treatments,“plant damage” (percent).

Figure imgf000053_0001
Controlled release formulations A- 1 12 & A- 1 13 of herbicide diflufenican were compared to the non- controlled relase reference Brodal, cf.Table 11. Independent of the application rate the efficacy profile against common grasses and weeds was comparable (A-l 12) or better (A-l 13) in this study. Alongside the herbicidal efficacy profile the tolerability of soja against both controlled release formulations significantly increased for both tested application rates on soja. For the high application rate of the controlled release formulations of 100 g/ha plant damage was reduced to 1/4* compared to the non-CR reference Brodal.

Process B (solvent removal induced encapsulation)
In a second embodiment the encapsulated actives are produced by colloidal encapsulation, which provides excellent control of particle and phase properties.
General Synthesis In a typical synthesis in a first step the active was fully dissolved in a suitable solvent (cf. Table 12“solution A”). The same solvent was used to fully dissolve the polymer (cf. Table 12“solution B”). The organic solutions were combined and then added to the aqueous phase (cf. Table 12“solution C”) containing a stabilizer that allows for emulsification.
Subsequent high shear mixing yielded the intermediate emulsion. Briefly, dispersing of the“oil phase” was carried out using rotor-stator high shear mixing (Ultra-Turrax, SN25-25F) at 10000 RPM for 300 sec, however other methods for emulsification known to the skilled aretisan may be used as well.
The organic solvent of the resulting mixture was fully removed under vacuum, yielding a white dispersion. Further concentration of the dispersion, i.e. removal of water, was carried out using a centrifugation decanting step, yielding the final formulations B-l to B-5 as described in Table 13.
In order to increase the electrolyte content of Example B-5, the solution obtained after concentrating was mixed 1 : 1 (v:v) with a 4 mol/L aqueous NaCl solution, obtaining example B-6.

The same solvent was used to fully dissolve the polymer, see solution B, Table 12. Polymer to active ratio may be adjusted to tailor the release profile. Both organic solutions, solution A+B, were combined and then added to the aqueous phase, ref. solution C. Subsequent high shear mixing yielded the intermediate emulsion.

The organic solvent of the resulting mixture was fully removed under vacuum, yielding a white dispersion. Further concentration of the dispersion, i.e. removal of water, may be carried out using a centrifugation-decanting step, yielding, the final formulations Bl-5 and B7-8 as described in Table 13. In order to increase the electrolyte content of Example B-5, the solution obtained after concentrating was mixed 1 : 1 (v:v) with a 4 moPL aqueous NaCl solution, obtaining example B-6.

Biology tests in soil drench applications for formulations obtained according to process C
Samples were supplied as aqueous suspensions as described in Table 19 and were applied at 8, 10, 20 mg a.i. per cucumber plant by applying 60mL soil drenches. Plant health (damage) was examined 3 / 4 / 5 / 7 / 10 and 14 days after application by visual inspection of leafs (% leaf area with chlorosis+necrosis) and shoot fresh weight measurement. Samples C-4 and C-9 to C-l l were tested versus untreated control cucumber plants (UTC) and a non-controlled release fluopyram (V elum® SC400), cf Table 8.
For samples C-9 to C-l l the degree of leafe damage correlates with polymer shell thickness. In particular towards later inspection times, e.g. for lOd & l4d this trend becomes clearly pronounced as the cucumber plant was exposed to active for a longer time and the shells becoming more and more permeable in the order from thin to thick polymer coating (cellulose acetate to fluopyram ratio was 0.23(C-9), 0.33(C-l0), 0.39(C- 11)) cf. Table 19
Table 23: Proved efficacy of controlled release formulations obtained according to process C, % damaged leaf area was in all cases significantly reduced and in the majority of cases fully eliminated, i.e. comparable to the untreated control (UTC). The significant improved is evident accros all dose rates, i.e. 8, 10, 20 mg fluopyram per plant. Results represent average of triplicate analysis. Number in bracket indicates application rate in mg active/plant
