The invention relates to chemical plant protection products, namely, a means for weed damage in crops of cultivated plants.
Herbicidal agents are known, containing L containing active ingredients - parabanic acid derivatives, organic solvents and surfactants - diesel oil or alkylaryl polyglycol ethers. These include 10 s, for example, a herbicidal agent based on 1-methyl-3-phenyl parabanoic acid tlj.
However, the known means of this16
groups are not effective enough with respect to certain types of weeds, and in higher doses they harm crop plants.
The aim of the invention is to reduce the phytotoxicity of a herbal medicine based on para-biic acid derivative in relation to cultivated plants.
This goal is achieved by the fact that, as a derivative of parabanova 25

This agent is prepared by simply mixing all of its ingredients.
Below are parabanic acid derivatives of general formula 1, which are the active ingredients of the herbicidal agent. Example. To conduct experiments, plastic flower pots with a capacity of 30,000 cm, containing clay sand with 1.5% humus as a substrate, are used. Seeds of experimental plants are shallowly sown separately by class. Immediately after this, during the pre-emergence treatment, an aqueous preparation of a gericidal agent is applied to the surface of the earth with the help of nozzles. required concentration of the active substance. After the preparation is applied, the vessels are slightly watered with water to cause germination and growth of the plants and at the same time to activate the active substances. The vessels are then closed with a transparent plastic crush until the plants start to grow. This plant affects the uniform germination of the experimental plants, 6 if chemicals do not interfere with this. For post-harvest treatment, plants, depending on the form of growth, are grown in test vessels up to a height of 3 -10 cm and then treated with an aqueous preparation of a herbicidal agent. In this case, the vessels are closed. All experiments were carried out in a greenhouse, and for varieties that like heat, they create a temperature of 25–40 ° C, and for temperate varieties - 15–30 s. The duration of the experiment is 3 to 6 weeks. The evaluation is carried out on the scale O - 10O. In this case, O means no damage or normal shoot, and 100 means a dry shoot or complete destruction of at least the aboveground parts of the plants. Tables 2-.4 summarize the experimental plants, the active substances in kg / ha, and the results of the experiments. Table 1

TABLE 3 Claims of the invention. A herbal agent containing an active substance — a derivative of parabanic acid, a solvent and a surfactant — differs from the fact that, in order to reduce phytotoxicity with respect to cultivated plants, it contains as a derivative of parabanic acid. the compound of the general formula B ko R. is methyl or c clopropyl; 2-fluorophenyl, 3-fluoro-4-fe. ., f 9 6 Noxiphenyl, 3-chloro-4-phenoxyphenyl, as a solvent - Shshlohexanol, as a surfactant - a fraction of mineral oil with a boiling point of 210-280 ° C, and oxyethylated castor oil at a Bes. parabanic acid, cyclohexanol, ({mineral oil with boiling point 21O - and ethoxylated castor oil equal to 16.6: 20.8: 54.2: 8.4, respectively. Sources of information taken into account during the examination 1. Patent US No. 2895817, cell 71/92, published 1959 ( ootyoty).
