Abstract

This invention relates to an insecticidal composition in the form of a suspension concentrate containing a synergistically effective combination of active substances from the class of neonicotinoids, namely clothianidin and thiamethoxam, and from the class of pyrethroids – beta-cyfluthrin, as well as auxiliary components such as dispersant, wetting agent, defoamer, biocide, antifreeze, thickener and water.

Description

This invention belongs to means of protection of agricultural cultivated plants from insect pests, namely to a new insecticidal composition in the form of a suspension concentrate containing a synergistically effective combination of active substances from the class of neonicotinoids, namely clothianidin and thiamethoxam, and from the class of pyrethroids - beta- dcifluthrin.

The creation of new combinations of already known biologically active substances, the joint use of which leads to a mutual strengthening of biological activity, and preparation forms that contribute to the manifestation of this increased biological activity, is still relevant. This allows the most affordable way to reduce the application rates of drugs and, thus, to reduce the ecological burden on the environment while simultaneously expanding the spectrum of action of the drug used to fight pests, as well as overcoming or preventing the development of resistance to individual components of a synergistically effective combination of active substances. One of the typical problems encountered in the field of pest control is the need to reduce the dose of an active ingredient in order to reduce or avoid adverse ecological or toxicological effects, while still maintaining effective pest control.

Description

Like other neonicotinoids, clothianidin is an insecticide of contact, intestinal, and systemic action, effective against sucking insects, including the families of Soieoriega, Notoriega, and Oiriega. It is mainly used for treating seeds, as well as for soil and green mass treatment.

Clothianidin at the biochemical level prolongs the opening of sodium channels of the insect's central nervous system. Nerve impulse transmission is blocked and the insect dies from nervous overexcitation. Clothianidin begins to work immediately after use, while its predecessor, thiamethoxam, needs time to be metabolized to clothianidin. The balance between water solubility and strong sorption capacity to organic soil particles protects clothianidin from leaching and provides long-term protection due to bioaccumulation.

A chemical substance, a pesticide (neonicotinoid), is used (including in mixtures with other active components) in agriculture to combat harmful insects.

Physical and chemical properties Light-cream crystalline powder without odor. Physical

Zo Characteristics: Molecular weight 291.7; Melting point 139.1 "С; Vapor pressure at 2570-6.6-10-6 mPa (5.0-10-8 mm Hg); Solubility in water at 2570-41 g/l. Effect on harmful organisms Thiamethoxam is an insecticide of systemic and contact-intestinal action with translaminar activity, suppresses spiny-sucking insects. Mechanism of action. The active substance is quickly absorbed by the plant and moves through the xylem to the untreated parts of plants, affecting the nicotinic-acetyl-choline receptors of the nervous system of insects. Effective against cryptic insects that feed on the underside of the leaf (translaminar effect). The period of protective action is 2-4 weeks. Resistance. Does not give cross-resistance to other neonicotinoids. According to studies by the Bayer company, the metabolite of thiamethoxam is clothianidin, which, in its in turn, has a greater speed of impact on harmful organisms and greater stability in plants and soil.

Application phytotoxicity. Thiamethoxam is non-phytotoxic. In agriculture.

The insecticide is widely used to combat isopods, thrips, lepidoptera (including passing beetles) and stilts. However, the action against the greenhouse whitefly is insignificant. Preparations based on thiamethoxam are used against pests of wheat (bread weevil, harmful turtle bug), barley (leech), potatoes (Colorado beetle, wireworm) and many other vegetable, fruit and flower crops.

Preparations based on lambda-cyhalothrin and thiamethoxam are used against pests of wheat (bread weevil, harmful beetle, bread beetles, intrastem flies, cereal aphids, wheat thrips, bread fleas), barley (leech, intrastem flies, cereal aphids), oats (leech ), cabbage (cabbage aphid, cabbage moth, cabbage scoop, whiteflies), peas (pea aphid, pea fruit eater, pea seed). Preparations based on thiamethoxam, mefenoxam and fludioxonil are used against rape pests (cruciferous fleas). During trials of the thiamethoxam-based actara drug in the south

of the Rostov region in relation to the California scab on apple trees showed that spraying,

carried out at the beginning of the molting of larvae weakly restrained the further reproduction of scale insects - the total number decreased by only 35 95, but the damage of fruits decreased by 82 95, and the number of spots on fruits by 96 95. The low biological effectiveness of thiamethoxam against scale insects is due to the fact that the active the substance quickly spreads through the phloem, but weakly penetrates into the subcutillary cells, the contents of which are sucked up by the shields. Thanks to systemic and translaminar properties, insecticides based on thiamethoxam (actara) can be used to treat tubers, which allows you to protect plants starting from the seedling period, even with early pest infestation. In a private homestead. In private homesteads, thiamethoxam-based preparations are allowed to be used to combat pests of potatoes (Colorado beetle), indoor flower and decorative plants, currants (aphids). In floriculture. Registered preparations based on thiamethoxam for combating pests of indoor and balcony flower plants (aphids, scale insects, whiteflies, worms, thrips). Briquettes with the active substance are introduced into the pre-watered soil under the plants.

One of the typical problems encountered in the field of pest control is the need to reduce the dose of an active ingredient in order to reduce or avoid adverse ecological or toxicological effects, while still maintaining effective pest control. In accordance with the present invention, it was found that a new insecticidal composition, including thiamethoxam, beta-cyfluthrin and clothianidin, demonstrates enhanced insecticidal activity compared to the individual components

Insecticides based on two active substances are widely used in practice, such as substances from the classes of neonicotinoids - imidacloprid and clothianidin (patent applications KI 2008122962).

There is also an insecticidal composition in the form of a suspension concentrate, which we have taken as a prototype, containing imidacloprid (I) and a synthetic pyrethroid - lambda-cyhalothrin (II) in synergistically effective quantities in combination with such components as surface-active substances, antifreeze, antifoam, thickener and water, mineral or vegetable oil and as adhesives contains an aqueous emulsion of acrylic copolymer. As surfactants, it contains at least two substances selected from the group including oxyethylated tristyrylphenol phosphate, ethoxy(propoxylated) polyarylphenol, oxyethylated alkylphenol, salt

From polycarboxylate, condensed alkyl naphthalene sulfonate, block copolymers of ethylene/propylene/oxide, ethoxy (propoxylated) fatty alcohols, salts of alkylaryl sulfonates, polyethylene glycol ethers of complex esters of fatty acids and polyhydric alcohols. Antifreeze contains ethylene or propylene, or di(tetra)ethylene glycol, or glycerin in the amount of 0.5-10 wt. 9, as an antifoamer - polydimethylsiloxane, as a thickener - xanthan gum. Contains biocide, UV stabilizer, dye and acidity regulator. Patent KO2395201 Published: 07/27/2010

However, the mixtures described in the above-mentioned patents are not effective enough in the fight against a number of insect pests, which served as a reason for the creation of a three-component mixture that is effective against almost all types of insect pests.

The purpose of the claimed invention is to expand the assortment of pesticide mixtures that solve the problems of reducing the dosage and expanding the spectrum of effective action in the fight against insect pests of agricultural crops, in particular cereals, providing long-term protection against pests in the field, preventing the risk of resistance, the possibility of using the drug in a wide temperature range range The technical result consists in strengthening the insecticidal effect compared to the insecticidal effect of individual components, namely obtaining a synergistic effect, obtaining a prolonged effect on the pest due to the combination of various active substances from the class of neonicotinoids with different periods of metabolism in plants, reducing the rate of application and the frequency of treatments and, thereby reducing the negative impact on the environment.

The task is solved in an insecticidal composition in the form of a suspension concentrate containing active active substances from the neonicotinoid class and an active active substance from the pyrethroid class, in addition, the composition has auxiliary ingredients, namely a defoamer, a thickener, an antifreeze biocide, a dispersant, a wetting agent and water , according to the invention, thiamethoxam and clothianidin are used as active substances from the class of neonicotinoids, and beta-cyfluthrin is used from the class of pyrethroids, with the following ratio of components, wt. 9o: beta-cyfluthrin 1-10 thiamethoxam 5-50 clothianidin 1-10 dispersant 0.1-10 wetting agent 1-10 defoamer 0.1-2 biocide 0.1-2 antifreeze 2-25 thickener 0.1-2 the rest to water 100 95.

As a dispersant, the composition may contain at least one substance selected from the group consisting of sodium or calcium lignosulfonate, alkyl sulfonates, alkyl aryl sulfonates, aryl sulfonates, lignin sulfonates, alkyl diphenyl ether disulfonates, polystyrene sulfonates, alkyl phosphate ether salts, alkyl aryl phosphates, styryl aryl phosphates, sulfate ether salts of polyoxyethylene alkyl ethers, use polyoxyethylene alkyl aryl ether sulfates, ethylene oxy ether salts , polyoxyethylene alkyl ether phosphates, polyoxyethylene alkyl aryl phosphate ester salts, salts of naphthalene sulfonate formalin condensates.

As a defoamer, the composition may contain silicone defoamers, for example polydimethylsiloxane.

As a biocide, the composition may contain at least one substance selected from the group including

B-chloro-2-methyl-3-(2H)-isothiazolone or hexahydro-1,3,5-tris-(2-hydroxyethyl)sym-triazine, benzoic acid and its salts, sorbic acid and its salts.

As an antifreeze, the composition may contain at least one substance selected from the group consisting of ethylene or propylene glycol, di(tetra)ethylene glycol, glycerin.

As a wetting agent, the composition may contain at least one substance selected from the group consisting of oxyethylated or propoxyethylated alkylphenols, polyoxyethylated alcohols, amines, ethoxy-propoxy block copolymers, sulfates or phosphates of polyoxyethylated alcohols or their salts, ethoxylated tristyrylphenols, sulfates or phosphates of ethoxylated or propoxylated tristyrylphenols or their salts, alkyl sulfates or aryl sulfates or their salts, alkyl sulfonates or aryl sulfonates or their salts, lignosulfonates condensed alkyl naphthalene sulfonates, including such compounds as sodium 2,2-dinaphthylmethane-6,6-disulfonate, sodium dibutyl naphthalene sulfonate, salts of polycarboxylates, derivatives of sulfosuccinates.

Synergism between the three active components of the insecticidal composition according to the invention was evaluated in laboratory conditions by comparing the effect on the pest of both individual components and a mixture of three substances.

Common cereal aphid (5spigarnii dgatipit), common leech (Otssheta teiaporib5) and harmful turtle bug (Epgudavieg ipiedgiserbv) were used as test insects for conducting these tests.

For experiments, aqueous solutions of the insecticidal composition were prepared according to

With the invention in different concentrations of active substances, thus obtaining experimental samples.

To study the effectiveness of individual substances, aqueous solutions of monocomponent drugs known from the state of the art were used: Dantop VG (clothianidin 500 g/kg), Aktor VG (thiamethoxam 250 g/kg) and Solfak, ME (beta-cyfluthrin 50 g/l).

The test plants of wheat were applied with solutions of tested samples of the insecticidal composition according to the invention, as well as solutions of the above preparations based on individual active substances by spraying.

After the solution dried, the test plants were placed in a container with harmful insects.

After the control time, the percentage of insect death was determined. At the same time, 100 95 meant that all insects died, 0 95 meant that no insects died.

The insecticidal efficiency (death of insects in 95) from a mixture of 3 active ingredients was determined by Colby's formula (Soibu 5.E., Uueez 15, p. 20-22, 1967):

Ehug-(X- My) Ukh i i DdDL100-kh"7U"2/10000, where X-death of insects in 95 from clothianidin with a concentration of t, μg/l;

U-death of insects in 95 from thiamtoxam with a concentration of n, μg/l; 7-death of insects in 95 from beta-cdcifluthrin with a concentration of K, μg/l;

Ehug-death of insects from the simultaneous use of clothianidin, thiamethoxam and beta-philuthrin with concentrations of т, п and К, respectively.

From the examples given in the table, it can be seen that in all cases the actual effectiveness for the mixture of active substances is higher than the value calculated by the Colby formula, that is, there is a synergistic effect.

Beta-cyfluthrin is an effective pyrithroid active ingredient. It is much less used in agriculture compared to alpha cypermethrin, lambda-cyhalothrin. According to beta-cyfluthrin, such a strong development of pest resistance is not noted. Beta-cyfluthrin provides a quick stop effect against pests.

The high efficiency of this active substance allows you to expand the window of application of this insecticidal combination. Synergism, which arises from the combination of beta-cyfluthrin with clothianidin and thiamethoxam, especially against pests of the class of angiosperms and semi-orenopterans, allows to reduce the rate of the active substance per hectare, which allows to reduce the negative impact on the environment.

Clothianidin has a rapid biological effectiveness and when it penetrates into the plant already within a few hours after application, it provides its protection from pests. From a chemical point of view, clothianidin is a metabolite of thiamethoxam, and this process in the plant is long-lasting in cava.

Thanks to this, the rapid and long-lasting systemic action of this insecticide is ensured at the same time.

Thanks to the synergism of two active substances of the neonicotinoid class, we can reduce the rate of application of active substances per hectare, which allows us to reduce the negative impact on the environment.

The active use of insecticides in agriculture leads to the emergence of resistance in pests and an increase in the rates of use of drugs on the main crops.

Weather conditions have a significant impact on the effectiveness of insecticide application. In recent years, we have observed alternating wet and dry periods during the growing season.

It also complicates the effective use of insecticides. Most of the insecticides on the market are single-component contact insecticides based on pyrethroids or systemic based on neonicotinoids. These two groups of active substances have both their advantages and disadvantages. For example, pyrethroids have a quick stop effect on pests, but their period of protective action is quite short and is 5-7 days. Also, they do not control pests that live in hiding, such as thrips, because they do not have a systemic effect. The biological effectiveness of active substances from the class of pyrethroids begins to manifest itself at low average daily temperatures. There is a practice of fighting against pests on winter rape, starting from 5 "C average daily temperature. On the other hand, the active substances of this group do not work well at a temperature higher than 422 "C, which is a significant problem when using pyrethroid insecticides in the summer growing season of crops. After all, in the hot months, the air temperature may not drop to the level of 22 "С even at night. Neonicotinoids are systemic insecticides with an intestinal mechanism of action. The active substances of this group are effective in the fight against pests that live in hiding. After all, penetrating into the cell sap of plants and moving acropetally, active

The substance even gets into untreated aerial parts of the plant. The period of protective effect of such active substances is 14-21 days. This makes it possible to obtain a prolonged effect and reduce the number of treatments of agricultural land against pests. Neonicotinoids begin to work effectively at an average daily temperature of 8-10 "C to 25 "C, so it is not suitable for early spring applications against pests.

Synergistic insecticidal composition containing beta-cyfluthrin, thiamethoxam and clothianidin as active ingredients. The combination of these active substances shows a synergistic effect in the fight against insect pests during foliar treatment of agricultural crops.

Manufacturing process: 1. In reactor A, a viscous mixture of water (10-20 95 of the final volume of the series) and xanthan gum in the amount of 5 g/l is prepared. 2. In reactor B, the remaining volume of water is poured into the series and clothianidin 50 g/l, thiamethoxam 200 g/l, beta-cyfluthrin 50 g/l, glycerol 100 g/l, benzoic acid 3 g/l, sodium lignosulfonate are added 15 g/l, polyoxyethylene-n-nonylphenyl ether 50 g/l and organosilicone 2 g/l. 3. The contents of reactor B are passed through a ball mill, which reduces the particle size of the active substance to approximately 5 μm. 4. The content of reactor B passed through the mill is poured into reactor B. 5. The content of reactor A is added to reactor B with constant intensive stirring.

Bring the volume to the final volume of the series with purified water and thoroughly stir the mixture for 2 hours.

The use of the proposed invention will allow: - to expand the range of controlled pests; - use the drug in a larger temperature range; - to obtain a prolonged effect on the pest due to the combination of various active substances from the class of neonicotinoids and the class with a different period of metabolism in the plant; - reduce the application rate and the frequency of treatments and thereby reduce the negative impact on the environment.
