    when the mass ratio of compounds V: VI is 1: P, equal to 1: 0.125-1, in the amount of 1.125-2.5 kg / ha.
    The invention relates to chemical methods of controlling weeds in crops of cultivated plants by treating them with a herbicide and an antidote. We know how to control weeds ij, according to which substituted chloroacetanilides of the general formula CH7-A are used as a herbicide, where R R A is methyl or ethyl hydrogen or methylJ. substituted in the corresponding methyl, methox group or chlorine pyrazolyl, 1,2,4-triazolyl or 2, D-dimethylpyrrolyl. However, when using this herbicide in effective doses, crop plants are often damaged, i.e., the selectivity of the herbicide is not sufficient. The aim of the invention is to increase the selectivity of the method of weed control. This goal is achieved in that, according to the method for controlling weeds, plants are treated with a mixture of a derivative of chloroacetanilide of the general formula CH3 methyl, ethyl; hydrogen, methyl hydrogen, methyl, methoxy, chlorine, with 1,3-oxazine bottom of the general formula 3 SIRN; L --СНС12 hydrogen, methyl, hydrogen, methyl, ethyl, propyl, 1-ethyl-n-pentyl, or the ratio of compounds is 1: 0.125-1, in the amount of kg / ha, according to the second varioba treatment is carried out with a mixture of chlorine acetanilide formula j. one of 1,3-oxazine formulas CH3 CH% - sleep g I II H about

Plasticate boxes for seedlings with a length of 51 cm, a width of 32 cm and a height of 6 cm are filled with sand mixed with clay with a pH of 6 and a humus content of about 1.5%. In this substrate there is a wide range of maize or wheat. Besides; iToro, they are added .J as unwanted leafberry plants and foxtail. Unsterilized land additionally contains. viable weeds that increase the population of unwanted plants. Thus, the arable land is sown with the sowing of cultivated plants, which is clogged with weeds. Active substances and antidotes are introduced both in pure form and in the described mixtures. To do this, they are distributed in water in the form of an emulsion or suspension (water serves as a carrier) and sprayed by means of a thin-layer device onto the ground immediately after sowing and before the emergence of seedlings of experimental plants. In some cases, the herbicidal agent is also introduced into the ground before sowing. After sowing and processing, the crates are irrigated with water and covered with a transparent plastic cover until seeding the shoots. These measures ensure uniform germination and germination of plants. Yav (incubator at 18-30 C. Observation is carried out until corn develops into a phase of 3-5 leaves (after this stage the herbicidal agent does not act, which is also confirmed by experiments conducted in open ground). Evaluation of the average action is carried out on a scale from 0 to 100. At the same time, O means normal germination and development of plants in comparison with untreated and control plants, 100 corresponds to complete suppression of germination or dying of plants. At the same time, it is learned that, for example, in corn and even under completely normal conditions, and without any chemical treatment, individual plants appear ugly or repressed. Example 2. Field experiments. Open field experiments were carried out on small experimental sandy soil with pH 5-6 and humus content.1-1.5%. Pre-emergence treatment is carried out either immediately after sowing, or no later than three days after sowing of cultivated plants. The weed flora is represented by various species compositions of natural populations (only the dominant Do). The active substances and antidotes, as well as their mixtures, are suspended or emulsified in water (carrier and distribution to the medium) and the experienced units are treated with the help of a tractor mounted sprayer. With a lack of natural precipitation, additional watering is carried out to ensure the normal growth of cultivated plants and weeds. All experiments were carried out for several months so that the development of cultivated plants could be observed until the formation of seeds. The assessment of the average action of the herbicidal agent is also carried out on a scale from 0 to 100. Table 3-6 shows the results of the pre-emergence treatment (Table 3 and the experience in the greenhouse).

    however, the phytotoxicity of herbicidal acetanilides of formula 1 is significantly reduced (or completely eliminated) with respect to cultivated plants, such as corn and cereals.
