    The biological properties of the compounds (Formula 3) are confirmed by the results of tests carried out in which plants or grains are processed according to several methods, which depend on the nature of the plants used for the tests and the reactions considered.
    In the following, the word “solution” must be understood as either an aqueous solution if the active substance is hydrolyzable or an aqueous dispersion of a wettable powder with 20% of the active substance.
    According to the first method of root treatment, used for peas, sprouts at the age of 2-6 days of two varieties are placed on the surface of a solution containing 1-10 g / l of the test substance, and the root is immersed. After 3-6 days, the biometric and morphological evolution of sprouts is observed and noted.
    For other plants, such as beans, tomatoes, corn, cotton sunflower, cucumbers, chrysanthemums, at the stage of 2-4 leaves, as well as fruit trees, pineapples, etc. treat leaves by spraying with a solution containing 110 g / l of the test substance. Then, the biometric and morphological development of plants after 8, 25 days and 1 month is noted. For some plants (for example, fruit trees), 6 months are observed.
    You can also immerse plant seeds (such as corn, tomatoes, cotton, barley, peas, mustard) for 24 hours in a solution containing 1-10 g / l of the test substance. The treated seeds are then sown and biometric and morphological changes over time are recorded.
    In most barley tests, the seeds of this plant germinate the surface of a solution containing 110 g / l of the test substance. Biometric and morphological changes in sprouts after three and five days are recorded.
    In tests for fruit ripening, immature test fruits taken at the same plant development level are immersed for 24 hours in a solution with a concentration of up to 110 g / l of the test substance. Note the internal and external maturation of the fruit. Using these methods, they study several methods of the effect of compounds (Formula 1) on plant growth. Example 1, Inhibition of rota. Epicotyle growth and distance between nodes of the treated forms are measured relative to the control samples. Under these conditions, at a dose of 1 g / l dd of peas and barley and 5 g / l for maize, sunflower, cotton, beans, tomatoes, compounds 1, 25, 28, 29, 35 and 36 cause growth inhibition at 1645 %, while methionine does not affect these plants. Example 2. Modification times. Vity - side shoots. The control is carried out by counting the number of side shoots and by measuring them for a time. Under these conditions, it is observed that with doses of 1-10 g / l, compounds 1, 3, 4, 9, 17, 21, and 33 cause an increase in branching and a significant development of lateral shoots in tomato, facet, and chrysanthemum. Compounds 15, 16, 26, 29, and 30 slow down the development of lateral shoots. Example 3. Defoliruyuschee action. The control is carried out by counting the number of fallen leaves to assess the properties of the active substances to accelerate defoliation. Under these conditions, it is observed that at a dose of 10 g / l of compound 3, 20, 30, 31 and 34 cause defoliation by 50-86%. In doses up to 1.2-5 kg / ha, compounds 1, 10. and 20 cause 7-7-90% defoliation of leaves in cotton. Methionine (control) does not give any defoliation. . Example 4. Impact on ripening and coloring of fruits. The immature fruits of the blond are moistened with test compounds and, for comparison, with methionine, the control sample being saved for comparison. After wetting, the fruits are placed in transparent vessels with CO absorbers, and everything is done in the greenhouse. Under these conditions, it is observed that the control samples ripen in 12 days, the fruits treated with methionine ripen in 10 days, and the fruits treated in Compounds 1 and 4, in 3 days. In experiments in natural conditions with pineapples (the treatment is carried out by spraying), the acceleration of ripening is observed when using compounds 19 and 20. This regulates the harvesting, which can last up to 12 days. Example 5. Effect on flowering and formation. In the control and in the experiment, the number of flowers is recorded and the slowing down or acceleration of bloom is observed. Under these conditions, it is observed that at a dose of 5 g / l, compound 10 increases the yield of beans by 10%, while in the same dose, compounds 11, 12, 19 and 23 cause a slowdown in the flowering of beans and cucumbers by 5-6 days; in experiments under natural conditions, compounds 19 and 20 cause the onset of flowering of the pineapple. Example 6. Effect on germination. A slowdown in the germination of the treated seeds with respect to the untreated seeds of the control samples is noted. Under these conditions, compound 22 is observed to inhibit the germination of maize seeds. This Inhibition is temporary at a dose of 1 g / l and becomes crucial at a dose of 10 g / l. Example 7. The effect of epinastia. Spiral twisting (torzii) of plant stems is observed. Under these conditions, it is stated that compound 18 at a dose of 10 g / l causes severe deformations of the pea roots. Example 8. Effect on leaf staining. . Compare the green color of the leaves during processing, by spraying with the color of the new leaves on the side shoots. Under these conditions, it is observed that compounds 3, 4, 9, 20, 21, 22, 23, 24, 30, and 31 impart a thick green color to the new leaves of the beans and tomato. This is confirmed by the determination of chlorophyll, the amount of which in the leaves treated with the above compounds doubles, moreover, experiments in the field show that some compounds (formulas) applied to cotton cause an increase (which: can reach up to 50%) of the number of boxes and improvement (up to 40%) of flower induction. In addition, some compounds are very effective, causing a group fall of olives, which greatly facilitates the harvesting of fruits. The examples show the remarkable properties of compounds (Formula D) that can be used in all types of plants, and industrial, cereal, horticultural, vegetable, shovel, ornamental, medicinal, and perfume plants for increasing yields, easing borka (for example, accelerating the ripening of fruits) stimulation of branching, unification of appearance, emergence of flowering induction, delayed flowering with boroba with moro, growth inhibition for the production of compact plants, etc. The doses used vary widely, depending on the desired effect, the type of plant, the stage of treatment, the soil and the climatic conditions.
    conditions Doses from 0.1 dd to 10.0 g / l are preferred. In practice, compounds (formulas) are rarely used in pure form. They are usually part of compositions which contain, in addition to the active substance, fillers and surfactant.
    The fillers can be of organic and mineral, natural or synthetic origin. The active substance is combined with it in order to facilitate its application: to plants, seeds or the soil, as well as to facilitate transportation and handling. Fillers can be solid (clays, natural or synthetic silicates, resins, waxes, solid fertilizers) or liquid (water, alcohols, ketones, petroleum fractions, chlorinated hydrocarbons, liquefied gases).
    The surfactant may be emulsifying, dispersive or wetting agents (ionic and non-ionic) such as polyacrylic acid, ligninsulfinic acid, ethylene oxide condensates with fatty alcohols, fatty acids or fatty amines.
    The agent according to the invention can be prepared in the form of wettable powders, dusts, granules, solutions, emulsifiable concentrates, emulsions, concentrates in the form of suspensions, and aerosols.
    Wettable powders contain 20-95% by weight of active principle and, in addition to a solid base, up to 0.5% of a wetting agent, 3-10% by weight of a dispersant, and when necessary, 10% by weight of one of several stabilizers and / or other adhesives, such as penetration adhesives or agents, preventing lumping, coloring, etc.
    The wettable powder may have the following composition, wt.%:
    Active principle 50 Calcium lignosulfate (anti-flocculant) 5
    Isopropyl naphthalene sulfonate (wetting agent) 1 Silicon dioxide (prevents lump formation) 5 Kaolin (filler) 39 Emulsifiable concentrates used for spraying usually contain, in addition to a solvent and, when necessary, a co-solvent, 10-50% by weight of active principle, 220 % by weight of appropriate additives, such as stabilizers, penetration agents, corrosion inhibitors, dyes and adhesives.
    Suspended concentrates, also applicable for spraying, are prepared by preparing a liquid, stable product which does not precipitate. They usually contain, wt%: active principle 1075, surfactant 0.5-15.0, 0.1-10.0 wt% anti-sedimentation agents (protective colloids and thixotropic agents) 0.1-10 appropriate adjectives 10 (antifoaming agents, corrosion inhibitors, stabilizers, penetration agents, adhesives), and as a base water or an organic liquid in which the active principle does not appreciably dissolve. Some organic solids or mineral salts can be dissolved in the base in order to counteract the sediment.
    or freezing fuses (for water),
    As the proposed agent, aqueous dispersions and emulsions can be used, for example compositions obtained by diluting with a water of a wettable powder or an emulsifiable concentrate. These emulsions can be of the type water-in-oil or the type oil-in-water, and also have a thick texture (consistency of mayonnaise).
    The proposed tool may contain protective colloids; adhesives silt thickeners, thixotropic agents, stabilizers or creators of intracomplex organoelement compounds, as well as other known active principles with pesticidal properties, in particular insecticides, fungicides or growth regulators; The compositions can be applied to plants in various ways (spraying the ground part of the plant, wetting the seeds of the plants, soil, roots or fruits, pollination, with irrigation water, etc.).
