При мер 13. На сельскохоз йственных микроучастках рассаживают растени кукурузы А-619 при расходной норме растений на гектар. Растени обрабатывают, примен расходную норму от 9,5б до 1,68 кг/га, препаратом, содержащим соединение Recrystallization from methyl alcohol. The esters are prepared as follows. Example 10o A stirred slurry suspension containing 27.7 g (0.1 mol) of N- (2-chlorop-3-pyridyl) -phthalic acid semi-amide and 300 ml of methyl alcohol is added 71 g (0.5 mol) of boron fluoride etherate (. Due to the exothermic reaction, the temperature rises from 21 ° C to 33 ° C. The stirred mixture is heated under reflux for 2k hours. When cooled to -10 ° C slowly at -10 ° C 1000 ml of an aqueous solution of sodium bicarbonate is added to 0 ° C. After stirring for half an hour at from Traditions are collected solid, washed with water until neutralized, and dried in air at 25-30 ° C.

When implementing the proposed method, the active principle can be used in pure form or in combination with auxiliary agents in liquid or solid form. For the preparation of plant rota regulators, the active principle is mixed with auxiliary agents, which include diluents, fillers, carriers and conditioning agents, in order to obtain compositions in the form of finely divided solids, granules, tablets, wettable powders, dust, solutions and aqueous dispersions or emulsions. Thus, the active principle can be used together with an auxiliary agent as a finely divided solid product, organic liquid for dissolution, water, wetting agent, dispersant or emulsifier, as well as any combination of the latter. Representative finely ground solid carriers and fillers suitable for use in the proposed plant growth regulating compositions include talc, clay, pumice, silica, diatomaceous earth, quartz, Fuller earth, sulfur, cork powder, wood powder, nut flour , chalk, tobacco dust, activated carbon, etc. Typical liquid solvents include Stoddard solvent, acetone, alcohols, glycols, ethyl acetate, benzene, and ToPo. Plant growth regulators according to the invention, in particular, liquids and wettable powders, usually contain one or more surfactants in quantities sufficient for making the formulation easy to disperse in water or oil. Surfactants include wetting agents, dispersants, emulsifiers and suspending agents. Normally acting principles are applied in a composition containing one or more auxiliary agents that promote uniform distribution of the active principle. Application of liquid or finely divided solid formulations based on the active principle is carried out by conventional methods using, for example, sprayers, engine sprayers, manual and mechanical sprayers and sprayers Sprayers. The compositions can also be applied to aircraft. The proposed formulations contain approximately parts of the active principle, approximately 1-50 parts of surfactant and approximately 4-9 parts of solvents, all parts being given by weight in terms of total weight of the composition. When choosing an appropriate flow rate for processing, it should be remembered that the exact amounts depend on the processing method, plant variety, soil conditions and other factors. The preferred consumption rate is 0.056-516 kg / ha, although more may be used depending on the above factors. high rates from. 5b kg / ha. This invention does not relate to the use of phytotoxic consumables that have a herbicidal effect. The proposed formulations affect the regulation of the development of unproductive components in maize plants, both male (panicles) and female (ear) in this expression. regulating the development of reproductive components in maize means modifying the normal sequential development of these components before maturation. These modifications are expressed primarily as a delay in the development of the panicle, Inhibition of the growth of the bending branches of the panicle, changes in the number of ears, their shape, position, number of grains, speed of the pistil tableting phase, and so on. The proposed method includes changing the development of the reproductive components of healthy maize plants by treating them with an effective non-lethal amount of the composition until the early stage of development of the above-mentioned reproductive components or during it (reproductive differentiation). As a result of this treatment, the size of the panicle can be reduced or it can be removed, thereby reducing or eliminating the work that is needed in the case of hybrid corn seeds, which consist in manual removal of panicles. In addition to this, the number of seeds per unit of arable area can be increased, moreover, before or during the early stages of the development of ears. Compounds 1-9 are tested according to the method below; Example 11. Corn A-619 plants are grown and thinned in order to achieve a uniform culture. "Before the chemical treatment, all underdeveloped or retarded plants are removed. The active principle is prepared by adding 50 or 100 mg of the active principle to a ml of acetone and 7.5 ml of Vrda. As a surfactant, the ds is 0.25% Twien 20. A Devilbiss 152 spray on plants is applied to the plants during the early stages of the development of the reproductive components by a chemical with a consumption rate of 10 or 20 mg per plant. Results are evaluated by comparing the treated plants with the untreated control. Toxic chemicals appear to be effective in regulating the reproductive components of maize plants if, by treatment, at least 25% inhibition of the formation of side branches of panicles is achieved compared to control plants. According to the proposed method, the chemical chemicals 1, 2, 5, 6 have an inhibitory effect in the amount of 50-7 on the development of side marks of panicles. Compounds 3, 7, 8, and 13 inhibit this development by. In addition, flowering is inhibited. : Compound Flowers, 22 Control Example12. In another test, corn plants are treated with a preparation of the type described above based on the polyamide M- (2-chloro-3-pyridyl) -phthalic acid. In tab. 2, we present the results (of the reaction of the plants) of the test, which consist in adjusting the height of the ears, increasing the speed of the spudding phase of pistillate columns and partial sterility. Starting from germination with. As can be seen from the table. 2, the claimed invention relates to the treatment of phthalic acid semi-amides before or during the early stage of reproductive differentiation. The latter takes place at different times depending on the variety on the variety of corn plants, as well as on the surrounding conditions. For example, the differentiation of male reproductive components in Gaspe variety corn begins during the formation of grain, while the A-619 reproductive differentiation starts from 8 to 12 days after germination. The determination of the period of reproductive differentiation is known to the specialist. As an illustration, the deadline is that adopted in the USA in the middle west of the country, namely, from 25 to 25 days after germination. For varieties of corn in other countries, the correct time may be within the range of 1 to tO days after the harvest. - For corn A-619, the preferred processing time is 7 to 12 days after germination. Example 13. Corn plants A-619 are planted on agricultural microplots at plant consumption per hectare. Plants are treated, using the consumption rate from 9.5b to 1.68 kg / ha, with a preparation containing the compound
