Description

The invention relates to an insecticidal composition in the form of a water-suspension concentrate, suitable for applying to seeds of agricultural crops an effective amount of a known insecticide from the group of neonicotinoids - imidacloprid, which is a compound of formula (I).

1- (6-chloro-3-pyridylmethyl) -N-nitro-imidazolidin-2-ylideneamine (see: US Pat. No. 4742060, EP No. 0192060).

An important feature of imidacloprid is its ability to easily penetrate from the treated seeds into the root zone, from where it is adsorbed together with water and then transported to seedlings. Thus, the plant at an early stage of development is protected from pests living in the soil, including those that transmit viral diseases. This property is associated with the widespread use of imidacloprid in compositions and methods intended for both presowing treatment of seeds and their protection against pests during storage and transportation.

US Pat. No. 5,849,320 and RF Patent No. 2243657 describe an insecticidal coating for maize seeds containing imidacloprid as an insecticide in an amount of from 0.005 to 50% based on the weight of the seed, a binder is a copolymer or a polymer of vinyl acetate and ethylene or a copolymer of vinylidene chloride in an amount from 0.01 to 15%, based on the weight of the seed and the filler, which is a mixture of diatomaceous earth and silicon dioxide in an amount of from 0.01 to 50% also in terms of the weight of the seed. The composition is diluted with water and treated with seeds using equipment with adjustable heating (50-30 ° C).

The disadvantage of the composition is the absence in its composition of a surfactant that provides hydrophobic properties of the film, and the need for heating the seeds during processing, which may have a negative effect on their germination.

In US patent No. 5950360 and RF patent No. 2168855 describes a tool and method for seed treatment using a suspension on a gel basis. Etching is carried out with the drug without dilution with water. Since the viscosity of the preparation is very high, the standard equipment used is unsuitable: the seeds cannot be distributed evenly, and a significant part of the preparation remains on the walls of the pickling machine, which entails the loss of the active substance.

The closest analogue of the present invention is an aqueous nicotinoid composition for seed dressing, described in the application for the grant of US patent No. 2005/0215432. The composition contains as active substance at least one insecticidal or acaricidal effective nitroimino or nitroguanidine compound, including imidacloprid, and a mixture of the following components by weight:

a) 2-10% of a surfactant comprising at least one anionic substance;

c) 4-20% of an inorganic solid carrier;

c) 3-20% antifreeze;

c) 3-20% antifreeze.

As anionic surfactants, the composition may contain at least one compound selected from the group consisting of sulfates or phosphates of polyalkoxylated polyarylphenols, sulfoalkylamide, alkylaryl sulfonate, sulfates or phosphates of ethoxylated alkyl phenols, lignosulfonate. As nonionic surfactants, the composition may contain alkyl or aryl phenol ethoxylates, ethoxylated fatty alcohols, ethoxylated polyarylphenols, for example ethoxylated tristyrylphenol.

As inorganic solid carriers, the composition may comprise titanium dioxide or magnesium or aluminum silicates, talc or mixtures thereof.

As an antifreeze, the composition may contain ethylene or propylene glycol or glycerin.

In addition to the main components, the composition may also contain such auxiliary substances as film-forming polymers, thickeners, for example xanthan gum heteropolysaccharide with biocide, dye and antifoam.

In the description of the invention there is only one general example for the preparation of suspension concentrate. Any experimentally confirmed data on the physicochemical properties of specific preparations, their storage stability, and their biological activity are completely absent.

As the experiments showed, the preparation made according to the recipe of sample No. 13 (table 3) (without the addition of fungicide) is significantly inferior in terms of physical properties and biological activity to Bayer’s famous Gaucho drug 600 KC (suspension concentrate for seed treatment) (See The pesticide Manual, 14 Ed., P. 598).

The composition of the drug according to the prototype: % Imidacloprid 45 Glycerol fifteen Tristyrylphenol Sulfate one Ethoxylated Nonylphenol 2 Titanium dioxide fifteen Clay 0.1 Dye (Pigment Bright Red C) four Heteropolysaccharide 0.2 Biocide 0.1 Water up to 100%

Obtained according to this recipe, the drug has a high viscosity, which makes it difficult to work with it, and reduced stability during storage. When processing seeds, it is not evenly distributed over their surface, and the film coating of sugar beet and flax seeds obtained as a result of processing with this preparation has a low elasticity and partially collapses during storage and transportation, which ultimately leads to a decrease in yield.

The object of the present invention is an insecticidal composition for wet dressing of seeds in the form of a water-suspension concentrate containing imidacloprid as an active substance and having improved properties compared to the prototype.

It turned out that the complete or partial replacement of a solid filler, for example titanium dioxide, which is described as a “drying agent” in the description, with mineral or vegetable oil or a combination of these oils with polyethylene glycol of different degrees of polymerization (polyethylene glycol-200 and polyethylene glycol-400) allows to obtain the drug with excellent working properties: it is evenly distributed on the seeds, it is easily dried on the seeds after their treatment using standard equipment and forms a flexible film, e exposed to abrasion and destruction during the seed storage time.

The composition in accordance with the present invention has the following composition in wt.%:

Imidacloprid 4.76-59.3 Surface-active substance, 3,5-10,5 including anionic 0.5-9.0 Inorganic solid carrier 0-2.5 Antifreeze 2-10 Vegetable or mineral oil 0.5-10 Polyethylene glycol-200 or Polyethylene glycol-400 0-10 Thickener 0.04-0.2 Biocide 0-0.1 Dye 0-10 Anti-foaming agent (polydimethylsiloxane) 0-2 Water the rest is up to 100%

As a surfactant, the composition contains a mixture of anionic and nonionic surfactants selected from the group consisting of ethoxylated di- and tristyrylphenol, ethoxylated tristyrylphenol sulfate, ethoxylated nonylphenol, sodium alkylnaphthalene sulfonate, lignosulfonate, ethoxylated fatty acid.

Bentonite or crystalline silica are used as the inorganic solid support. These components can also act as thickeners and are components of film former.

Xanthan gum heteropolysaccharide or carboxymethyl cellulose are used as a thickening agent or suspension stabilizer, which also remain on the seed in the form of a film after drying. To protect the heteropolysaccharide from microorganisms, a biocide in an amount of not more than 0.1 wt.% Is introduced into the composition.

Irgalit Rubin or Pigment Bright Red C are used as a dye, and polydimethylsiloxane as an antifoam.

Another object of the invention is a method for protecting cultivated plants at an early stage of their development from insect pests living in the soil surrounding germinating seeds, which consists in applying an effective amount of the insecticidal composition described above to seeds of cultivated plants. In the context of this invention, such cultivated plants are sugar beets and flax.

17.7 g of water, 15 g of glycerol are charged into the reactor. With stirring, 2 g of ethoxylated nonylphenol, 1 g of tristyrylphenol sulfate, heated to a temperature of 45-50 ° C, are added. Stirred for 10-15 minutes, after which 45 g of imidacloprid, 4 g of Bright Red C Pigment, 15 g of titanium dioxide were added. Mix thoroughly until a homogeneous suspension is formed and grind in a bead mill. 0.2 g of heteropolysaccharide and 0.1 g of biocide are added to the resulting product, after which the physicochemical parameters of the preparation are determined.

The result is a very viscous suspension, which is difficult to disperse in water.

The properties of this sample are presented in table 2.

Example 4

Assessment of the stability of various types of formulations during storage.

To assess the possibility of storing drugs for 2 years at a temperature of minus 5 to plus 35 ° C, the following tests were carried out:

1. Accelerated storage test: the preparations were kept in a thermostat at plus 54 ° С for 2 weeks (CIPAC MT 46.3 method and Surfactants and Specialites for Plant Protection, Rhodia);

2. Test for frost resistance: the preparations were kept in a thermostat at minus 20 ° С for 10 days (GOST 9.707-81, CIPAC MT 46.3 technique);

3. Heat aging test: the preparations were kept in a thermostat at plus 45 ° С for 60 days (GOST 9.707-81, CIPAC MT 46.3 methodology and Surfactants and Specialites for Plant Protection, Rhodia);

Repeat tests 3 times.

The viscosity of the preparations, both before and after storage, was determined on a Brookfield viscometer, stability according to CIPAC MT 161, dispersion was determined according to the CIPAC MT 187 method using a Fritsch laser particle analyzer. The results are presented in table 3.

Example 5

Initial biological tests on flax and beet seeds were carried out under laboratory conditions. The main evaluation criterion was the quality of the film obtained on the surface of the seeds. Sowing quality of seeds was determined after storage of the treated seeds for 6-10 months. The determinations were carried out in accordance with GOST 20797-87 "Seeds of sugar beet pelleted. Sowing qualities. " To characterize the quality of the seeds used indicators such as germination, purity and moisture of the seed material. These indicators are normalized as follows:

Name of indicator Norm,% Germination, not less 90 Cleanliness, not less 98 Humidity, not more (for seeds treated with a composition of organic substances) 8

For each seed sample, the measurement was carried out in 4 replicates.

The results of the studies are presented in table 4.

From the obtained data it can be seen that the quality of the seed treated with one of the patented samples is close (or slightly exceeds) the quality of the seeds treated with Bayer "Gaucho" 600 KS, used as a reference standard, and significantly exceeds the quality of the seeds processed with the prototype.

The same tests were carried out for flax seeds in accordance with GOST 53325-2005 “Seeds of agricultural plants. Varietal and sowing qualities. "

Norms of indicators for flax seeds:

Name of indicator Norm,% Germination, not less 80 Cleanliness, not less 97 Humidity, no more 12

According to the data obtained, we can conclude that the drug does not have a negative effect on the sowing quality of flax seeds, unlike the prototype (see table 5).

Field biological tests of the formulation were carried out on flax flax - in the fight against flaxen fleas and on beets - in the fight against beetroot fleas, ordinary beetroot weevil and wireworms.

As a reference standard, the preparation f. Bayer Gaucho, KS (600 g / l imidacloprid).

Beet and flax seed dressing was carried out by wet dressing method in accordance with the “Guidelines for dressing seeds of agricultural crops”, Moscow, “Kolos”, 1984. This type of dressing consists in applying suspensions of preparations to the seed surface with simultaneous wetting with liquid at the rate of 5 -15 l / t

The work was carried out on a PS-10 universal pickling machine. A diluted suspension of the preparation was prepared in a special tank. Seeds from the loading device were fed into the pickling hopper of the machine, from where they, together with the suspensions, were fed to a rotating disk, where they were evenly distributed along the perimeter of the pickling chamber, covered by a uniform layer of the suspension, which after drying formed a film on the surface of the seeds. Pickled seeds were discharged from the PS-10 through a screw system and bagged.

The advantages of this processing method are the economical use of the drug due to the good dosage of the liquid, the possibility of simultaneous application of insecticidal and fungicidal protectants and fertilizers, slight moistening of the seeds and the absence of the need for their subsequent drying. When pickling with wetting, the drug was mixed with water.

Tests on flax (grade Alpha) were carried out in the Tver region (VNII flax). Blue (Aphthona euphorbiae Schr.) And black (Lonqitarsus Parvulus) linen flaxes were identified as a harmful object. The size of the plots is 150 m ² , the number of replicates is 4 for each option. The results are presented in table 6.

According to the test results, it can be concluded that the imidaclopride-based formulation is highly bioavailable in the treatment of flax seeds. The period of protective action is sufficient for the flax to undergo a “seedling” phase, during which the flax flea harmfulness is greatest.

Tests on sugar beets (Ramonsky MS-73 hybrid) were carried out in the Voronezh region, Zarechnoye agricultural complex. Beetroot fleas (Chaetocnema spp.), Ordinary beetroot weevil (Bohtynoderes punctiventris Germ.), Wireworm (Agriotes spp.) Were identified as a harmful object. The size of the plots is 0.5 ha, the number of replications is 3 for each option.

The biological effectiveness of the drug was determined by reducing the number of pests and plant damage relative to the control and was calculated using the Abbot formula:

, где

where

where A is the death of insects in the experiment (%);

In - the death of insects in the control (%).

The test results are presented in tables 7-9.

In addition, etching quality was assessed. Seed and planting material can be treated in advance (for 8 months - 15 days), as well as before sowing (for 15 - 1 day). In the case of an insecticide disinfectant, it is more efficient to carry out early dressing in order to avoid damage to the seeds by pests during storage.

The quality of the etching depends on strict adherence to the norms of consumption of the drug in accordance with the recommended norms, the stability of concentration and the norms of supply of the drug, the uniformity of its application on the surface of the seeds, the adhesion and retention of the drug.

The completeness of the etching (P) was determined by the ratio of the mass of the drug actually applied to the seeds to the established rate of its consumption:

where X is the mass of the pesticide actually applied to the seeds, g / t,

N - established rate of pesticide consumption, g / t.

The mass of the pesticide actually applied to the seeds was determined by the calorimetric method.

For each seed sample, the measurement was carried out in 3 replicates.

The results of this assessment are presented in table 10.

One of the advantages of this drug is to obtain a durable film coating that does not crumble during storage of seeds.

The effect of seed dressing quality on sugar beet crop is presented in table 11.
