    This invention relates to plant growth regulating chemicals and may be used in agriculture. The purpose of the invention is to increase the retardant effect. The proposed N- (2,4-dichloro-6-methylphenyl) -imidazole-5-carboxylic acid or its potassium salt at a dose of 0.62-1.25 kg / ha more effectively suppress grain growth than the known analogue in structure. When used in the same dose, the compounds according to the invention reduce by 5-15% more effectively the growth of cereals. 2 tab.

    This invention relates to plant growth regulating chemicals and may be used in agriculture.
    The purpose of the invention is to increase the rewarding effect.
    Using the proposed compounds, typical growth-regulating effects are achieved, which, compared to the known compounds, can be achieved in different cultures at lower dosages. They regulate the plant metabolism inherent in plants and can thus be used to target the substances found in plants as well as to facilitate harvesting. They are suitable for the general control and suppression of unwanted vegetative growth, without leading to the death of plants. The suppression of vegetative growth plays a large role in the case of many single and dicotyledonous crops, since this may reduce or completely prevent lodging. The growth regulating activity of compounds as a growth suppressor in cereals (corn, soybeans, tobacco, cotton, Norbonne peas, rapeseed, rice, grass), as well as their ability to add the content of desired substances like carbohydrates (for example, sugar cane or crops) and protein in beneficial plants. The compounds show a very good improvement in fruit buds, especially in the case of citrus fruits.

    Agents can be used in the form of wettable powders, emulsifiable concentrates, spray solutions, fertilizers, mordant agents, dispersions, granulates or micro granules of conventional formulations.
    The proposed compounds, under their practical use under well-known conditions, can also be combined with known growth regulators. Such known growth regulators are compounds of the formula

    Formamido is used as the carboxylic amide. The reaction is carried out in the presence of inorganic acid in molar amounts at 50-200 ° C, especially at 100-170 ° C. Bisformal compounds of the formula On and respectively 116 can be easily prepared by known methods from known anilines (for example, from 2-alkyl-6-trifluoromethyl-aniline, 2-alkenyl, 2-hydroxyalkyl-6-alkylaminyl, 2-alkoxy) 6-alkylaniline).
    The salts of the compound of formula (I) can be prepared according to conventional salt formation methods, for example, by dissolving the compound of formula (I) in an organic solvent and adding acid, and in a known manner, for example, by filtering, isolated and, if necessary, purified by washing with an inert organic solvent.
    Physico-chemical characteristics of the proposed compounds are given in table. TO,
    Biological examples of growth suppression in cereals.
    In the test cups in the greenhouse, young plants of grain crops (wheat, barley, rye) in the 3rd leaf stage are sprayed before the collection with the proposed compounds in various concentrations of the biologically active substance (kg / ha)
    After untreated control plants have reached a height of growth of about 55 cm, in the case of all plants, growth and growth inhibition are measured, the percentage of growth of control plants is calculated. In addition, the phytotoxic effect of the compounds is observed, with 100% indicating growth arrest and 0% indicating growth, respectively, of untreated control plants. The proposed compounds have very good growth regulating properties.
    Retardant activity of the proposed compounds are given in table.2.
    The results of the experiments confirm the increased regulatory growth of plants activity of the proposed compounds.
