Definitions

  • the present invention relates to novel compositions which are applicable in the field of crop protection as an adjuvant, for example in combination with agrochemical active ingredients.
  • Agrochemical active substances in particular those which are applied postemergence by means of a spray and which are taken up in the plants via the leaf, are frequently used in
  • the agrochemical formulations are mixed together with the tank-mix adjuvants in the spray mixture.
  • These "tank-mix" adjuvants have the aim of increasing the biological activity of the agrochemically active compounds, such as insecticides, fungicides, bactericides, herbicides, growth regulators, acaricides or nematicides and / or the applicability of the agrochemically active compounds, such as insecticides, fungicides, bactericides, herbicides, growth regulators, acaricides or nematicides and / or the applicability of the agrochemically active compounds, such as insecticides, fungicides, bactericides, herbicides, growth regulators, acaricides or nematicides and / or the applicability of the agrochemically active compounds, such as insecticides, fungicides, bactericides, herbicides, growth regulators, acaricides or nematicides and / or the
  • Adjuvants mean materials that are not themselves biologically active. The biological effect is e.g. improve by optimizing leaf adhesion, wetting, distribution or uptake. Some properties of the spray liquor or spray residue on the treated plant surface which can be optimized are suspensibility, emulsifiability, stability, solubility, pH, foaming, surface tension, vapor tension, plant tolerance, drift, droplet size or degree of coverage. Adjuvants may be subdivided into various chemical groups (e.g., surfactants, fatty acid esters, polymers, oils, buffers, organosilicon compounds, latex suspensions, etc.).
  • chemical groups e.g., surfactants, fatty acid esters, polymers, oils, buffers, organosilicon compounds, latex suspensions, etc.
  • adjuvants are of great practical importance and is described extensively in the literature (see, eg, CL Foy, DW Pritchard (Ed.), Pesticide Formulation and Adjuvant Technology, CRC Press, Ine, 1996, Boca Raton, Florida, USA; A. Knowles, Agrow Reports, Adjuvants and additives: 2006 edition, Informa UK Ltd, 2006, United Kingdom, Conference Proceedings ISAA 2004, Cape Town, South Africa).
  • oils to improve the effectiveness of pesticides by improving the wetting and spreading properties of the spray residues.
  • oils are mineral oils, vegetable oils and esters of these vegetable oils. It is known that vegetable oil esters improve the uptake of many pesticides into the leaf and that the very low volatility of vegetable oils increases the residual effectiveness of pesticides.
  • paraffin oil formulations as a summer spray and winter spray is known in practice (eg Oleocin® from Bayer CropScience).
  • US 5,580,567 compositions which contain, in addition to oil, an emulsifier system and a buffer. Advantage of these adjuvants is that the improvement of the biological effect and the ability to adjust the pH are summarized in one product.
  • US 3,977,322 discloses a composition containing a mineral oil and a vegetable oil which, in admixture, enhance the effectiveness of selective herbicides.
  • a synergistic herbicidal composition is described in US 4,755,207. These formulations contain a vegetable compatible oil (refined vegetable oil or high refined paraffin oil), a surfactant and hydrophobic mycobacteric spores.
  • ammonium salts Another group of adjuvants is that of ammonium salts. It has already been described in the literature that the effect of various active substances can be increased by adding ammonium salts. However, these are detergent-acting salts (for example WO 95/017817) or salts with longer alkyl and / or aryl substituents, which have a permeabilizing effect or which
  • Insects act (US 2,842,476).
  • An increase in activity e.g. by ammonium sulfate, for example, for the herbicides glyphosate and phosphinothricin described (US 6,645,914, EP-A 0 036 106).
  • ammonium sulfate as a formulation aid is described for certain active ingredients and applications (WO 92/16108), but it is there to stabilize the formulation, not to increase the effect.
  • adjuvants which contain various surfactants. These surfactants, like the ammonium salts, aim to improve their uptake into the plant.
  • ammonium is introduced into the formulations because the active ingredients used are used as ammonium salts, as is customary in particular in the widely used herbicide glyphosate (eg WO 07/050090, WO 05/1 17583, WO 05 / 013692, WO 06/050141, US 2003/104947, US 5,238,604, DE 197 52 552).
  • a separate ammonium salt is added.
  • WO 00/67573 describes adjuvants compositions for herbicides. In these, however, cationic emulsifiers are essential, while the compositions of the present invention contain anionic surfactants.
  • WO 02/34047 describes a formulation aid for pesticides, in which an ammonium salt is, however, present as a solution in water, not in particulate form.
  • the compositions of the present invention are anhydrous.
  • Prefabricated mixtures of ammonium salts and delivery promoters such as oils and / or surfactants in a single product are beneficial to the user, e.g. with regard to dosing accuracy and user safety (no transfer and mixing necessary).
  • ammonium salts in water-based adjuvant compositions is described in various publications.
  • compositions which contain, in addition to water and ammonium sulfate alkylpolysaccharides.
  • WO 05/046326 claims an improved uptake of nutrients into the fruit of the treated plant.
  • US 5,356,861 discloses the use of a composition for increasing the effect of glyphosate.
  • WO 03/092373 mentions formulations which, in addition to water and ammonium sulfate, contain an iminodipropionate as amphoteric surfactants. The aim of these formulations is to offer a complete solution as a "tank mix" for herbicides.
  • oil as a receiving conveyor in combination with ammonium salt, possibly mixed with other receiving-promoting surfactants, instead of the described water-surfactant mixtures would be a logical alternative.
  • adjuvant compositions either oil (s) or ammonium salt - A - included.
  • One of the difficulties in developing such formulations is the form of the ammonium salt.
  • the ammonium salts are in the dissolved form, resulting in a homogeneous liquid formulation.
  • the solubility of the appropriate ammonium salts is less than the necessary amount of the salt.
  • ammonium salt in the oil-based formulations will be in crystalline form, causing formulation problems.
  • the common ammonium salts are difficult to comminute because of their hardness, and ammonium salt-containing, oil-based formulations tend to have high viscosity after comminution.
  • Ammonium salts are also generally difficult to stabilize in oil-based suspension concentrates.
  • the present invention thus relates to an oil-based adjuvant composition containing

  • paraffin oil 4) fatty acid esters and mixtures of different fatty acid esters
  • oil-based adjuvant composition according to the invention in combination with formulations containing agrochemical active substances, is very suitable for application to plants and / or their habitat.
  • oil-based adjuvant compositions according to the invention have a low viscosity and a very good stability, and in particular that no significant crystal growth of the ammonium salt was observed even after storage at changing temperature. It is also unexpected that they show significantly better biological activity than the most similar compounded adjuvant compositions. Incidentally, the oil-based adjuvant compositions according to the invention surprisingly also exceed in their activity analogous preparations which, in addition to the other components, contain either only ammonium salt or only oil. Such a synergistic effect was unpredictable due to the above-described prior art.
  • the oil-based adjuvant compositions of the invention are also characterized by a number of other advantages.
  • the number of necessary "tank-mix” applications is reduced because several properties to be optimized have been combined in the adjuvant compositions according to the invention
  • the user will therefore need to mix his pesticides only with one instead of several mixing partners in the spray mixture
  • a further advantage is that when diluting the adjuvant composition according to the invention with water, the pH of the Spray mixture is controllable by the selection of the ammonium salt in the product.
