Example 8. The test of growth stimulation, a) Experiments in the greenhouse.
 In the seedling pot filled with sand, 3x30 maize kernels were planted, in each case 10 grains were left untreated, 10 grains were treated according to example 10 with Placebo etching agent that does not contain biologically active material (10 more With a biologically active substance containing an etching agent, the pots were placed in a greenhouse with optimum temperature and humidity conditions for maize. The number of germinated grains was calculated in percent. On the 14th and 28th day after sowing, divided the height and green mass of the plants. The germination rate was determined as a percentage, and the height and green mass were correlated with the corresponding reference value (100).

With “,) | In seedling pots sized 20x20 cm filled with sand and placed in a greenhouse, they planted beans, carrots, flax, paprika 3 tomatoes, barley, millet, and spent post-harvest treatment with a biologically active substance according to the proposed method with a dose of 0.1 kg racemate - biologically active substance / ha or 0.2 kg of the racemate biologically active substance / ha. AT . at 4 weeks of age, the green mass of the plants was determined and compared to untreated control plants.
The results are presented in table 2.

From Table 2 it can be seen that plant crops such as flax, tomatoes, spinach and barley, treated with a biologically active substance with a dose of 0.1 kg / ha, have achieved more favorable results, while for the rest of the crops, a more favorable dose is 0 , 2 kg / ha. The increase in green mass compared to non-inverse control is 18-40%.

From Table 3, it can be seen that corn treated with a biologically active substance is 27% higher compared to both controls (untreated and treated with a Placebo bath), its green weight is 25% higher, and the harvest of cobs is 20% higher.
C. | Experiments in free ground on small businesses.
In 10x10 cases, maize was planted and a pre-emergence treatment of 50 EC-preparations containing the proposed compound in the form of the racemate according to Example 8 was carried out using 0.1, 1.0, 3.0 or 5.0 kg / ha of this compound. Post-treatment treated with a dose of 1.0 kg / ha. The spray liquid was prepared by diluting the preparation with rain water, using 500 liters of spray liquid per 1 ha. Concentration of the biologically active substance in the spraying fluid, depending on the dose of O5.02-1%, Delki dredged weeds.
The results are shown in table 4.

From table 4 it can be seen that the racemate is a biologically active substance with isob
stint when used for pre-treatment is already effective at a dose of 0 kg / ha, however, the most favorable effect is achieved at doses of 1-3 kg / ha. In this case, the plant is 21-27% higher, green mass is 27 -35% more, corn cob yield is 16-18% more than that of untreated plants, When applied for post-harvest processing of 1.0 kg / ha, the results are much worse,

From a 50% emulsion concentrate, a 3% spray liquid was obtained. From it, they were taken into a glass beaker so much that the bottom of the glass was covered with a layer of 2.5 mg / cm of the racemate of the biologically active substance. 20 specimens of anesthetized CO houseflies (Musca domestica) were placed in the glass. Dichlorfon (0,0-dimethyl-2,2,2-dichlorovinyl-phosphate) in the same doses was used as a comparative substance.

J Larvae Musca domestica, For the cultivation of the larvae of houseflies (Musca domestica), a suitable nutrient medium was prepared from the following components: kg wheat bran, 1 l milk, 10 kg fodder yeast and 6 g. Nipadin (P-hydroxybenzoic acid ethyl ester). 200 g of this nutrient medium were added to glass beakers, treated with such an amount of the racemate the biologically active substance so that the concentration in the nutrient medium is 250, 500 or 100 ppm. In this case, the biologically active substance in the form of a 50% emulsion concentrate is added to medium and then homogenized in the latter. We also conducted a control experiment without a biologically active substance. In prepared cups placed 50 larvae of flies at the age of 1 day, the cups were covered with a net from flies. In the assessment, it was determined how many individuals hatched from pupae,% of the control (see Table 6),

It is obvious from Table 6 that although the effect of dichlorfon is more radical than the effect of the proposed biologically active substance is slower, the toxicity of the latter is significantly lower and it does not have a choline-steroid inhibitory effect.
