Description

Description of the invention

The subject of the invention is an agent for controlling pests of crops in the form of an emulsion in water, intended for controlling pests of plants such as: spider mites, aphids, disfigurement, cuplets, thrips, mealybugs, and greenhouse whiteflies.

Mechanical pest control agents are known and commonly used, which consist of de-aromatized mineral oils known as "paraffin oils" as a base and oil-in-water emulsifiers. For example, from the patent application P.292296, a stabilized oil-in-water emulsion (o / w) is known, consisting of: a / an oil phase containing a lipophilic pesticide, optionally dissolved in an organic solvent, b / an aqueous phase containing a compatible, soluble in water, a pesticide, c) an emulsifying system capable of emulsifying or dispersing an oil phase in the aqueous phase, and d) a stabilizing or dispersing agent comprising titanium dioxide in an effective amount to further maintain or improve the stability of the emulsion. From another patent specification PL.168953, an oil preparation for plant protection products is known, which contains 74-81% by weight of paraffin oil with a viscosity of 15-28 mm ² / s at 50 ° C, containing 25-30% by weight of aliphatic hydrocarbons, 1 , 5-2 wt.% Sulfur and less than 5 ppm conjugated aromatic hydrocarbons; 19-26% parts by weight of an emulsifying composition containing 20-26 parts by weight of a fatty amine ethylene oxide ethylated with 3-7 moles of ethylene oxide with a hydrocarbon chain length of C8-C24, 16-20 parts by weight of an ethanolamine mixture composed of: 33-55 triethanolamine, 45-65 diethanolamine , 16-20 parts by weight of a fatty acid mixture containing more than 70% by weight of oleic acid, 25-30 parts by weight of d-sorbitan ester of fatty acids with a chain length of C12-C22, 9-15 parts by weight of sodium monoester sulfosuccinic acid and ethoxylated alcohol fatty acid or 8-14 parts by weight of sodium salt of sulfosuccinic acid monoester and ethoxylated alkyl phenols having a C9 alkyl radical and degree of ethoxylation on average 5 or 9.

Yet another patent specification PL.213148 discloses a pheromone preparation intended for reducing the number of insects, especially from the genus Lymantria, by disorientation, which is a solution of a pheromone in an organic liquid, the organic liquid containing a vegetable oil, preferably rapeseed oil or castor oil, or higher an aliphatic hydrocarbon or a mixture of higher aliphatic hydrocarbons, preferably a paraffin oil or a mineral oil, preferably having a viscosity of 0.01 to 100 Pa · s.

A drawback of the known vegetable oil emulsion compositions, for example rapeseed, soybean and sunflower oil, is the relatively low effectiveness in controlling crop pests.

In turn, agents based on mineral (petroleum) oils are highly effective in combating pests, but have a low biodegradation rate and pollute the environment with petroleum products. Mineral oils are also harmful and can permanently damage the lungs when inhaled in oil mist.

There are also known and commercially available agents for controlling pests by physical means, which use synthetic substances, for example silicone polymers. Synthetic agents are more harmful to the environment, humans and some crops compared to agents based on mineral oils.

Recently, there has been a tendency to use vegetable oils and other substances of natural origin in plant protection products. For example, from the description of the CN patent. 104886183 is known insect repellent composed of 10-15 parts. wt. cinnamon oil, 6-10 parts wt. garlic oil, 3-5 parts wt. clove oil, 0.5-2 parts wt. lemongrass essential oil, 1-3 parts wt. anthoxin essential oil, 2-5 parts wt. star anise oil and 50-65 parts. wt. ethanol. Another patent specification CN104542733 discloses an agricultural insecticide which is made from pine needles, eucalyptus leaves, tobacco, peach leaves, tea, cottonseed oil, sulfur powder and sodium chloride as the main raw materials, as well as calcium oxide, rosin, sodium carbonate and potassium dihydrogen phosphate and auxiliary raw materials.

The aim of the invention is to develop a new, biodegradable plant protection product with high effectiveness in destroying pests by the physical action of covering the surface of the pest with a thin sticky film, which blocks its movement and respiration.

PL 235 692 B1

The agent for controlling pests of crops, according to the essence of the invention, contains 80-95 parts of wt. saffron oil (oil from seed index (Camelina sativa), 3-8 parts by weight of unsaturated C14-18 and C16-18 glycerides, mono and diethoxylated (PEG - 17 Rape Oil) obtained from rapeseed oil, 0.5 to 3, 0 parts by weight of ethoxylated oleic acid (PEG-7 Oleate), 0.4-1.2 parts by weight of di (2-ethylhexyl) sulfosuccinate and 0.1 to 0.6 parts by weight of trisiloxane ethoxylate.

The agent is prepared by thoroughly mixing the ingredients of the composition until uniform.

The working liquid used for spraying the plants is an emulsion obtained by mixing 0.5 to 2.0 parts of the agent with 98.0 to 99.5 parts of water.

The invention will be described in more detail in the examples of its implementation.

Example 1. 93.1 kg of rice oil, 5.0 kg of mono and diethoxylated C14-18 and C16-18 glycerides (PEG-17 Rape Oil), 1.0 kg of oleic acid obtained from rapeseed oil were introduced into the mixer. ethoxylated, (PEG-7 Oleate) 0.7 kg sodium di (2-ethylhexyl) sulfosuccinate, 0.2 kg trisiloxane ethoxylate. The contents were mixed until homogenous. The agent was tested after dilution with water at concentrations of 0.9%, 1.2%, and 1.6%. When used to control the spider mite on strawberry and raspberry, it showed high effectiveness similar to that of synthetic agents. The measure was not phytotoxic to strawberries and raspberries. Used at a concentration of 0.9% and 1.2% to control fruit spider mite eggs on apple trees, it showed very high efficiency, higher than the standard preparation containing mineral oil. The agent in the tested concentrations of 0.9% and 1.6% showed high effectiveness in combating aphids.

Example 2. 87.5 kg of rice oil, 8.0 kg of mono and diethoxylated C14-18 and C16-18 glycerides (PEG-17 Rape Oil), 3.0 kg of oleic acid obtained from rapeseed oil were introduced into the mixer. ethoxylated (PEG-7 Oleate), 1.0 kg sodium di (2-ethylhexyl) sulfosuccinate, 0.5 kg trisiloxane ethoxylate. The contents were mixed until homogenous. The agent was diluted with water to a concentration of 1.0% to obtain a working liquid as a stable emulsion. The working liquid was used to control the eggs hibernating the fruit spider mite on apple trees in the early spring period. The effectiveness of destroying spider mites, compared to standard preparations, was very high.

Example 3 93.3 kg of rice oil, 4.0 kg of mono and diethoxylated C14-18 and C16-18 glycerides (PEG-17 Rape Oil), 2.0 kg of ethoxylated oleic acid obtained from rapeseed oil were introduced into the mixer. (PEG-7 Oleate), 0.5 kg of sodium di (2-ethylhexyl) sulfosuccinate, 0.2 kg of trisiloxane ethoxylate. The whole was mixed until homogenous. The working liquid was prepared by mixing 1.0 kg of the agent with 99.0 kg of water. The working liquid was used to combat aphids on roses during the summer. A high degree of efficiency has been achieved. There was no damage to the leaves.
