The table below shows the study of the determination of the optimal content of film-forming components. Their content varies from 0.005 to 0.05 per 1 g of the active substance. The composition taken without ethylene glycol. As a criterion, the strength of the protective layer created by the AOR by the proposed formulations on the surface of seeds of agricultural crops is examined. For the strength indicator of the protective layer, the percentage remaining on the per-layer is taken; surface composition after machining pickled seeds. The mechanical treatment of seeds simulates their processing in the dressing machines, transportation to the consumer, and consists in rotating the seeds in a ribbed flask-drum at a speed of 60-70 rev / min. To avoid injury to the grain, the mechanical impact time (bulb rotation) is 2 minutes. Method for determining the water-45 value of the protective layer of the drug. . It is based on the determination of the remaining pretreatment on the surface of the seed after the standard treatment with water. The time of contact of water with the seeds is Q. 30 s. The optimum content of the film-forming component is 0.01-0.04 g per 1 g of the active substance. The greatest strength of the protective layer is observed on the surface of nonsmooth beet seeds (93-95%), - the smallest - on seeds with a smooth surface of peas, corn (77-85%).

the coatings determine the content of the plasticizer EthyLeiglycol in the proposed composition. Table 2 summarizes the results of these studies. The composition of example 1 is used for the experiments. The content of glycol is varied from 3.6 to 9 wt.%. The introduction of a plasticizer improves the strength of the protective layer of the drug and reduces the polymer consumption per 1 g of the active substance to 0.02 g. At this rate of polymer, the surface of the seeds of sugar beet, ropoica, corn, millet is kept up to 99.6% of the protective layer, The optimal ratio of salt styromal: ethylene glycol is 1: 4.5-8.5 May, h. With a further increase in the plasticizer content, the role of plasticization at the polymer interface is gradually reduced, the solid matter begins to play a more significant role; destruction of intermolecular bonds in the polymer itself and with a higher content of plasticizer, the film strength decreases. The role of the surfactant - wetting agent (OP-7 or SP-10) in the proposed composition consists in improving the wetting conditions at the interface between water and an active substance, a disperser for CBP, adsorbing on the surface of a solid. the body (active substance) contributes to their grinding. Table 3 shows the results of studies of the effect of surfactant auxiliary additives, the OP-7 wetting agent and the CBP dispersant, on the degree of grinding (dispersibility) of the active substance in a liquid medium at roller grinding. The dispersed composition of solid particles characterizes the degree of dispersibility. solid particles in a liquid wetting agent, dispersant. The standard used in the study was the composition of Example 1. When choosing the optimal amount of OP-7 wetting agent, its content varies from 0.5 to 1.4% (pp} 1-5), the content of the remaining components in the composition remains constant . When choosing the optimal amount of CBE, its content varies from 4–8% (points 6–14), the content of the remaining compo- nents in the composition remains constant. The data in Table 3 show that the wetting agent OP-7 and the disperser CBP improve the process of grinding the active substance in the dispersed phase of the proposed composition. The optimum content of OP-7 wetter is O, 7-1, O wt.%, Disperser CBP 6-7 wt.%. With such a ratio of these additives in the proposed composition (Sec. 2, 3, 10: 11, 12, Table 3) the content of particles less than 10 µm is 60-64%. However, the presence of these additives does not prevent the process of agglomeration of solid particles; the content of parts greater than 10 µm is 12-20% in these samples. The introduction of aerosil and polyacrylamide protective colloids into the sys tem contributes to the stabilization of the dispersion of solid particles. A particle content of more than 10 microns is 2-3%. The same aa patterns occur when polyacrylamide is used as a stabilizer. In addition, the use of Aerosil will allow to obtain compounds that do not stratify into two phases (liquid and solid), when stored for two years. The mechanism of action of Aerosil is based on the formation of a gel-like structure in the bulk of the composition, which, due to its spatial network of solid particles, prevents sedimentation (sedimentation) of particles in the bulk. In compositions with an active substance content of 30 to 45% by weight (these compositions contain a sufficiently large amount of water - 15-22%) to improve the retention of the aqueous medium within the structure: - polyacrylamide is used. Its content in the proposed composition should be 0.10–0.12 wt.%.

1 acrylamide - protective colloid - stabilizer 6.0 Rhodamine C - dye, O Thrisodium polyphosphate - water softener (stabilizer) 1.0 Polyamino-alcohol - film gage, Water: ethylene glycol - (20:80 wt%, respectively) thinner Remaining Due to the fact that the crushability of the protective layer of a polymer similar to the composition is more than 10%, at a flow rate of the film-like skinny component of 0.3 g / g of active substance, it can be stated that biological indicators using a known composition will be significantly lower. When testing for biological activity in, compounds with polyamine alcohol are used as a comparison.

Example 1. Grain of corn Zherebkovsk 86, naturally contaminated with fungi of the genus RepsiIlum, causing mold growth of seeds, is treated with the compositions obtained in examples 1-10 at a flow rate of 1.2 kg of biologically active substance per 1 ton of seeds moistened with water (8 l per 1 t), After 5 days, the seeds are decomposed for germination in a moist chamber. The test was carried out at a temperature of 2-5 ° C for 8 days. After that, the infestation of seeds by fungi and their germination are determined. The data obtained (see tab. 5) shows that the proposed formulations effectively reduce the incidence of seeds from infection. The use of compositions with the salt of ferromal allows to reduce the prevalence of corn fungi by SSh-1YaN from 13.2 to 0.03%, and compositions with polyamino-alcohol from 13.3 to 0.3-0.6%. An increase in germination and a decrease in germination of seedlings (as compared with the use of the analog) allows an increase in the yield of green mass of corn by an average of 57 d / ha.

- Example 12. Yenisei sunflower seeds naturally infected with gray mold fungi (Botrytisci

ered), are treated with pred and amammi formulations at a consumption rate of 3 kg per 1 ton. The proposed formulas, compared with the analogue, increase the seed growth rate of seeds, reduce sunflower damage by gray rot and n times, which allows to increase the yield of green mass by 127 centners / ha (see table 6). ten

Example 13. Chishminsky early pea, naturally infected with fungi of the genus Fusariiim, is treated with the proposed formulations that completely suppress root rot of seeds, significantly increase field germination of seeds from 66, i to 91% (analog from 665А to 86%), Due to the increased field yield, the yield of green beans from 1 ha increases by 20 centners / ha (, 7).

Example 14, Seeds of Moscow wheat 33, naturally infected with fungi of the genus Fusarium, are treated with the proposed compositions and compositions prepared according to the composition of the analogue. Consumption of preparations 2.5 kg per 1 ton (according to the active substance). Field tests show that the proposed formulations reduce seed incidence with root gels from 37 to 0.5%, increase germination from 80 to 88.3%. The wheat yield, as compared with the analogue, increased by 4 centners per hectare Th. table.8) .35
