TITLE

Herbicidal spray process for the elimination of weeds and plants of all kinds by means of electrolytically produced oxidative radicals in water, with the addition of various salts.

TECHNICAL AREA

The invention relates to a new ecological herbicidal process for the elimination of weeds and plants, by means of oxidatively generated in saline water oxidative radicals, which are either produced outside in a separate tank, or the electrolysis technology with boron-doped diamond electrodes, is integrated in a motorized back or hand syringe, or other syringe types according to the preamble of the independent claims.

STATE OF THE ART

Stocks for controlling weeds and the elimination of plants have been used in herbicide use highly toxic chemicals and substances such as "Roundup", which leave on crops and in the environment highly toxic residues, and the environment heavy burden and In addition, they can cause serious damage to health to humans and animals. They are also very expensive.

The use of toxic herbicides in crop production is therefore very controversial today, and consumers prefer inexpensive, biologically and ecologically friendly to environmental herbicides and herbicides, without toxic ingredients or residues.

With the new invention in the application, by means of water, with the addition of ion-forming salts, electrolytically produced oxidative radicals, integrated in a motor-driven back or hand syringe and other types of syringes, or produced outside in a tank, all kinds of Weeds and plant constituents are destroyed ecologically, without the need for health and environmental harmful, toxic substances with residual effect must be used.

PRESENTATION OF THE INVENTION

The object of the invention is the disclosure of a new cost-effective, environmentally friendly and biological process for the destruction and elimination of weeds and plants without residues forming toxic chemicals using in water, with the addition of ions forming salts, produced by oxidation radicals oxidized with integrated electrolysis technology in a motor-driven back or hand syringe, or other syringe types or outside in a tank.

INTRODUCTION

Electrolytic Oxidative Water (EOW)

Electrolytic oxidative water (EOW) or chemically active water destroyed in sufficiently high concentration of weeds and plants by oxidative radicals not chemically, but physically.

Because of its high oxidative reduction potential (ORP), "active water" damages the cell wall membranes of weeds and plants by burning in the form of a cold oxidation. This process takes place in ultrafast superoxidations by oxidizing plant cells and tissues, respectively, and cold-burning and etching them.

The damaged cell membranes die and the weeds are gone.

This fact leads to a general death of the cells, respectively to cell death by cold combustion and causticization!

To the knowledge of the inventor are to date no scientific work in the field of herbicidal use by means of water, with the addition of ion-forming salts, electrolytically produced oxidative radicals, integrated in a hand or motorized back or hand syringe or other types of syringes , or manufactured in a separate tank, published together with the appropriate application technologies for practical field use.

THE SOLUTION OF THE TASK

The solution of the problem is defined by the features of the independent patent claims. According to the invention, the method of use in the herbicidal use for destroying weeds, mosses and plants shows the nature of the biocides, in particular the specific properties of the electrolyzed, oxidative water, of the

2 sen production of its salt concentration and salt composition, its redox potential, or its concentration in free oxidative radicals and total concentration of oxidative radicals, and its pH and amount of effort for an efficient injection process as a herbicide on.

The invention forms an integrated system in which the technical components for oxidative radical production in the water, the spray technology with the appropriate application technology in the form of a motorized backpack syringe, a hand syringe or other types of syringes are integrated or manufactured in a separate tank.

In 2-year laboratory and field trials, the appropriate salt combinations and oxidative radical concentrations in the spray herbicidal water were empirically and practically evaluated, tested and optimized for the herbicidal applications in 30 different agricultural and horticultural plant species and weeds.

The new combined application technique, along with the correct salt combinations and the corresponding concentrations of oxidative radicals are essential for the successful herbicidal use of electrolytically produced oxidative radicals in water and fulfill all the parameters for the optimal mode of action of the new herbicide process.

Further, the invention is innovative with respect to the production of oxidative radicals by the new method, the electrolysis with solid diamond boron doped electrodes that produce in the electrolysis of saline water with Na + and CL ions, especially Cl ions and not H + ions. Hypochlorous acid is indeed only a weak acid; However, it can still cause burns and even chemical burns due to their strong oxidizing effect. When they disintegrate, highly corrosive substances such as chloric acid and hydrochloric acid are formed, which can kill or even completely decompose organic tissue within a very short time.

The fact that boron doped solid diamond electrodes have an electrical potential of 3 volts not only enables the production of organically degradable hypochlorite compounds (OCL) or hypochlorous acid HCLO, but also ozone 03, H202, and hydroxyl radicals for the formation of mineral peroxides in mineral water.

The new herbicide process in plant protection with electrolytic oxidative radicals using special spray technology consists of the following technical components:

1. Motorized backpack syringe or hand syringe or other types of syringes.

2. One or more spray nozzles with pressure of 4-20 bar for the production of fine droplets with a drop size of ideally not more than 100 microns.

3. Alternatively, one or more storage water tanks for receiving the electrolytic oxidative radicals in the water in the volume dimensions of the respective syringe types, ideally 1-4000 liters or more.

4.1 or more circulating pumps, according to the liter power to be provided per hour with a minimum pressure of 4 atm. Including electronic control with »on« and «off switch, including non-oxidised lines made of Viton, Teflon or PVC or other suitable material.

5.1 or more spray pumps, for the application of the required spray amount of preferably 600-100) liters per hectare or more with "on" and "off" switch, including oxidatonsfreien pipes made of Viton, Teflon or PVC or other suitable material.

6. 2 pressure gauge and pressure control valves with return valve.

7. Measuring devices for the measurement of the oxidative radical concentration in the tank in particular the concentration of the free chlorine content including ozone.

8. An electrolyzer comprising an AC / DC transformer, optionally (1 10, 220 or 340 V), one or more electrolysis cells each having 2-3 or more electrodes of boron-doped solid diamond, incorporated in an electrolysis cell, as required, or platinum coated electrodes with electrical overpotential in an electrolytic cell with diaphragm, with volume flow meter and flow probe and corresponding control unit with manual and automatic cathode and anode load reversal (only possible with diamond electrodes electrolysis cell), built-in ammeter and Voltmeter and lamp function control, with automatic shutdown without volume flow, including lines and connections and control tap and sampling point, fine filter and return stop valve.

9. Power source from socket or battery, generated from the solar power system or power generator individually or by PTO, including controls and fuses.

The innovative application method of the invention includes 3 essential steps:

1. Preparation of the biocidal oxidative radicals in aqueous, saline solution insbesondre CIO (hypochlorite) HCIO (hypochlorous acid), H202 (hydrogen peroxide), 03 (ozone) and other peroxides from water minerals by means of electrolysis.

2. Spraying the prepared biocidal aqueous solution of oxidative radicals on the weeds to be destroyed and plants using the built-in sprayers nozzles. (Do not spray in rainy weather)

3 3. 1. Production of biocidal oxidative radicals in aqueous, saline solution by electrolysis.

The preparation of the biocidal oxidative radicals in aqueous, saline solution is done by 2 different, but complementary electrolysis.

The first method is implemented with electrolysis using boron-doped diamond electrodes. This results in a cocktail of oxidative radicals close to the "neutral region" with a pH of 6.4 to 6.8. In addition to OH-hydroxyl groups and 03, especially free chlorine (CI-) are formed at the anode, which together with the hydroxyl groups lead to the formation of hypochlorite OCl and hypochlorite acid HOCL, which are decomposed organically very rapidly. In order to carry out the electrolysis of the water cheaper and better in terms of power consumption, the salts are added to the water because of the improved electroconductivity, which are approved in organic farming. The electrolysis of these salt compounds also produces oxidizing reducing peroxide-di-sulfate, peroxide-di-phosphate and percarbonate.

These salts are preferably per liter of spray liquid: (for young weeds)

5 gr. NaCl (table salt)

0.3 gr. K2S04 (potassium sulfate)

0.3 gr. Na 3 PO 4 (sodium phosphate)

0.1 gr. Mg 2 SO 4 (magnesium phosphate)

After the electrolysis has taken place, this salt solution must have a concentration of min. Containing 1500 ppm or 1500 mg per liter of free chlorine with a pH of 7.6.

These salts are preferably per liter of spray liquid: (for adult weeds and plants):

10 gr. NaCl (table salt)

0.5 gr. K2S04 (potassium sulfate)

0.5 gr. Na 3 PO 4 (sodium phosphate)

0.5 gr. Mg 2 SO 4 (magnesium phosphate)

These concentrations may vary depending on weed and plant species and stage of growth!

After the electrolysis has taken place, this salt solution must have a concentration of min. 3000 ppm or 3000 mg per liter of free chlorine with a pH of 7.6. These salt compositions may also be different, depending on the type of plant and the purpose of use, both as salts and in their concentration.

For cost reasons, only salt NaCl can be used.

A second alternative method is implemented with cylinder electrolysis with diaphragm, where the electrolysis cells are separated from each other, consisting of an anode chamber and a cathode chamber. At the positive anode of platinum form acid-forming negatively charged anions in an acidic range of about 2.4 pH with negative charge, and forming at the negative cathode bases forming positive cations in an alkaline range of about 1 1 pH with a positive Charge.

These two acidic and alkaline aqueous electrolysis solutions can now be mixed as desired and sprayed on the weeds.

This electrolysis process has significant disadvantages such as, i.a. high energy consumption, unstable electrolysis solution, which decays rapidly, short life of the electrodes, no self-cleaning of the electrodes without dipolarity change.

Further, in such electrolysis, only hypochlorite and hypochlorous acid are formed, and therefore the herbicidal effect is reduced.

In the electrolysis of pure water without salt, the following oxidative radicals are formed:

ELECTROLYTIC PROCESS OF WATER

A variety of oxidative radicals are formed when water (H 2 O) is electrolyzed, for example:

(E0 is the standard redox potential) *:

02 + H + e- H02 EO = -0.13 V [1]

2H + + 2e- H2 EO = 0.00V [2]

H02 + H + + e- H202 EO = +1.50 V [3]

03 + 2H + + 2e- 02 + H20 EO = +2.07 V [4]

OH- + H + + e- H20 EO = +2.85 V [5]

H20 + e- H + OH- EO = - 2.93 V [6]

OH + e- OH- EO = +2.02 V [7]

4 ELECTROLYTIC PROCESS of water with salt NaCL

At the cathode side

Na + + e- Na

2Na + 2H20 2Na + + 2HH + H2

At the anode side, 2CI- 2e-C12

It must be mentioned here that C12 (chlorine gas) and OH- react as follows:

CI2 + 20H-CI O- + CI- + H20 or

CI2 + OH-HCIO + CI-

3.2. Spraying the prepared biocidal aqueous solution of oxidative radicals on the weeds and plants to be destroyed by means of special nozzles.

In order to completely wet and destroy the weeds and plants with oxidative radicals, a special spray technology is necessary.

The special spray nozzles guarantee complete wetting of the weeds and plants on leaf top and bottom on the style and in hard to reach places.

The water droplets are produced by an ultrafast airflow generated by side louvers close to the sonic velocity in the nozzle and are no greater than 50-100 microns.

The water droplets are thus distributed to all parts of the weeds or plants and there is a fine film on the whole plant surface, which leads to the destruction of the weeds and plant parts thanks to the oxidative radicals in the spray liquid.

EMBODIMENT OF THE INVENTION

To carry out the new herbicidal process for the destruction of weeds and plants in agricultural and horticultural crops, by means of electrolytically produced oxidative radicals, and special spray technology, the invention will be explained using the example of a motorized backpack sprayer.

The same technique can also be integrated into other types of syringes adapted to performance.

As a Grundspritzentyp is in this particular embodiment of the method, a motorized backpack sprayer, as offered by the company STIHL or HONDA on the market, adapted as follows to the new herbicidal technology and rebuilt. Here is the technical description of the STIHL back syringe model 420 and its performance data:

Technical specifications

11.5

The backpack syringe is additionally equipped, in a possible first version, with a small dynamo for power generation or in a second possible version with a 180 W cadmium 12 V battery with volt transformer.

An AC / DC transformer as a power supply allows the connection of an electrolysis cell with boron-doped solid diamond electrodes with electrical connection values of 50 V and 15 A.

At the syringe, in a first possible version of the embodiment, a miniature electrolysis cell is mounted and integrated into the fluid return system and connected to the associated electrical control and to the power supply. In the liquid return line is also a flow meter Built-in with electronic Sen-

5 sorsteuerung, which turns on the electrolysis cell at water flow and switches off without water flow. This cell is designed with sufficient performance that the 16 liter spray liquid can be treated electrolytically in about 30 minutes. This task solution of the technique is suitable for hobby gardeners and garden owners!

In a second possible version of the embodiment, for the professional use of a converted to the new technology backpack sprayer, it is recommended to produce the herbicidal spray liquid in a separate electrolysis device, depending on the need 50-100 liters or more of the electrolyzed oxidative solution produced per hour. For this application solution, a collecting tank of any size and 2 valve taps for the inflow and outflow and a circulation pump with preferably 100 liters per hour and with a pressure of preferably 4 bar, including electrical control and power cable connection 220V / 50 Hz needed and an electrolysis cell boron-doped full-diamond electrode coating including electronic control and / or a cylinder electrolysis apparatus with platinum electrodes including control necessary, or both at the same time as needed and use and production capacity.

At the top of the spray tube, the special nozzle is mounted with appropriate stainless holder, which is used together with the air blower of the backpack spray to produce a mist.

The liquid line of the special nozzle is connected by the spray tube by tubing to the pump of the backpack syringe. One or two variable pressure and flow control valve taps control fluid pressure and fluid flow.

To check the concentration of the electrolytically produced oxidative radicals, a probe for free chlorine in Rüchen-syringe tank or in the collecting tank of the electrolysis plant can be installed.

The equipped syringe can now begin the herbicidal treatment of the weeds and plants.

In the Rückenspritzentank resp. in the catch tank, clean tap water is filled. The appropriate salts are added to the water at the correct concentration for the particular application in the agitated state.

The electrolysis of the saline solution is set by the pump switch in function. Saline water is pressed through the electrode plates anode and cathode and at the same time electrolyzed with preferably about 15 A and 50 V or as needed with other intensities, thereby generating highly oxidative radicals in the water, causing burns or destruction of weeds and plants.

These salts are, for example, per liter of spray liquid: (for young plants)

5 gr. NaCl (table salt)

0.3 gr. K2S04 (potassium sulfate)

0.3 gr. Na 3 PO 4 (sodium phosphate)

0.2 gr. Mg 2 SO 4 (magnesium phosphate)

After the electrolysis has taken place, this salt solution must have a concentration of min. 1500 ppm or 1500 mg per liter of free chlorine with a pH of 7.6.

These salts are preferably per liter of spray liquid: (for adult weeds and plants):

10 gr. NaCl (table salt)

0.5 gr. K2S04 (potassium sulfate)

0.5 gr. Na 3 PO 4 (sodium phosphate)

0.5 gr. Mg 2 SO 4 (magnesium phosphate)

These concentrations may vary depending on weed and plant species and stage of growth!

After the electrolysis has taken place, this salt solution must have a concentration of min. 3000 ppm or 3000 mg per liter of free chlorine with a pH of 7.6. These salt compositions may also be different, depending on the type of plant and the purpose of use, both as salts and in their concentration.

For cost reasons, only salt NaCl can be used.

The concentration of the oxidative solution is analyzed either with an electric chlorine probe or chemically photo-optically with the DPD analysis method. Depending on the type and capacity of the electrolysis plant, there are also user tables that can serve to determine and calculate the Oxidative Radical concentration in particular the free chlorine, which is empirically easier. The following equation is relevant:

C = ppm of water x amperes x electrolysis time Log 5

When the concentration of oxidative radicals in the water solution is reached, the fueling process can begin, resp. the tank of the backpack sprayer can be filled from the collecting tank. If the engine of the backpack sprayer has started and the pump and the blower are running at the correct number of revolutions, the spraying work can begin.

The spray of maximum 50-100 micron droplet size, which is generated by the special air assisted nozzle, must now be sprayed on the plants so that the plants can be completely wetted everywhere. Only with a complete total wetting the herbicidal effect is 100%.

Claims (7)

In this spray work is especially important to note that all parts of the plant can be achieved. After drying the plant leaves, the herbicidal effect of the spray solution is complete. There is no risk of corrosion and no toxic residues remain on the plant matter. All radicals have been reconstituted into the starting salts. The cell tissues of the plants are burned or etched and the plant weeds can no longer carry out and breathe photosynthesis, which leads to the destruction of the plant population within 24-48 hours. The oxidative herbicide solution is a total herbicide without a selective effect. When spraying the herbicidal solution it is recommended to wear appropriate protective clothing, respiratory protection, rubber gloves and safety goggles, so as not to be struck by nontoxic sprays on bare skin. In case of insufficient effect, after-spraying in the interval of 7 days under normal meteorological conditions has proven to be ideal in numerous experiments. The application rate of the spray mixture depends on the weed population and plant species. 60 to 100 grams of broth per square meter or 600 to 1000 liters per hectare are usually sufficient. The novel herbicidal process can also be used with the appropriate nozzle covers for weed killing between plant rows. The new innovative herbicide process, is residue-free from a toxic point of view, without toxic by-products on and in plants and is also extremely suitable for organic farming and also very friendly to the environment and safe for the user with suitable protective clothing. The new herbicidal technology is, apart from the initial investment in the device acquisition much cheaper than conventional spraying with toxic herbicide products that are very expensive and toxic to humans, animals and the environment. claims 1.
