(54) HERBICIDE EQUIPMENT The invention relates to a chemical plant protection agent, namely, a herbicidal agent. A herbicidal agent containing derivatives of N-benzoyl-anthranilic acid, a solvent and a surfactant is known as an active substance, but the known herbicidal agent is not sufficiently effective in attributing certain types of weeds and causes damage to individual plants. Purpose of the invention is to enhance the herbicidal activity of the agent and the improvement of its selectivity. This goal is achieved by the fact that the herbicidal agent containing the active substance — a derivative of N-benzoyl anthranilic acid, a solvent and a surfactant — contains as a derivative N-benzoyl anthranilic acid a compound of the general formula C — X where X is hydrogen, chlorine, methyl , methoxy - hydroxyl, methoxy; R-phenyl, substituted chlorine and trifluoromethyl or two chlorine atoms; R is hydrogen, nitro, or its sodium salt, or its anhydro-pro-hydrated general formula where R has the specified meaning; X - watermark, xlope, meti mvotoksil; chlorine, trifluoromethyl, cyclohexanone and isobutanol as solvent, ethoxylated nonylphenol and oxyethylated castor oil as surfactant, in the following ratio of components, wt.%: Active-1C with substance Cyclohexanone 33.3 Isobutanol 25.0 Oxyethyl nonylphylene Castor oil 8.5 This herbicidal agent is prepared by simply mixing its ingredients. Tables 1 and 2 show the active substances of the general formulas I and I as effective herbicidal agents. For comparison, a known herbicidal agent is used containing compound A or B: -O as the active substance. Example 1. Experiments in a greenhouse. For carrying out the experiments, plastic masks with a capacity of 300 cm were used, with clay sand as a substrate containing 1.5% humus. Seeds of experimental plants are sown with shallow sowing, divided by species. For the cultivation of satiation, pretzarodishnye tubers are taken. The experiments were carried out before or after plant emergence with the use of an aqueous herbicide preparation consisting of parts by weight: active substance 20 (16.6% by weight); cyclohexanone 40 (33.3 wt.%); isobutanol as solvent 30 (25.0 wt.%) / ethoxylated nonylphenol 20 (16.6 per (7 mol of ethylene oxide per 1 mol of nonylphenol and ethoxylated castor oil f40 mol ethylene oxide; lene per 1 mole of castor oil as surfactant 10 (8.5 wt.%. During pre-emergence treatment, the herbicide is sprayed onto the soil surface directly after sowing. After applying the herbicide, the pots are irrigated to promote germination, growth and activating the herbicide. Then the pots are covered with transparent When the plants are post-harvest processing, they are grown in pots first to a height of 3-10 cm and then treated. Several plants are sown in cultivated pots, and others in pre-growing vessels, of which the last All the experiments were performed at 25-40 ° C for thermophilic plant species or at 15-30 ° C for temperate climates 2-4 weeks. During this period, plants are taken care of and evaluated for appropriate treatment on a scale from 0 to 100, whereby O means no damage to plants, and 100 means no germination of the plants or the complete destruction of at least the soil sprouts. The active substance in the herbicidal agent, the herbicide consumption (in terms of the amount of its active substance of the plant and the degree of their 1Competence are presented in Table 3-14. Experimental data presented in Table 3-14, evidence of the high effectiveness of the proposed herbicide agent, which affects a variety of weedy plants and does not damage the main cultivated plants.
