    This invention relates to a chemical agent for controlling weeds and undesirable vegetation, namely, a herbicide agent based on a synergistic mixture of substituted chloroacetanilides. Herbicidal agents containing substituted chloroacetanilides as active ingredients are known. These include, for example, an agent based on N-azolylmethylhalogenacetate nilides 1 and an agent containing the active substance N- (apkyl, alkoxyalkyl, alkenyl) - -haloacetanilides 2. However, the herbicidal agents of this group are not sufficiently effective for certain types of weeds. The purpose of the invention is to increase the efficiency of the herbicide agent based on substituted chloroacetanilides. This goal is achieved by using a mixture of 2-chloro 2, b-dimethyl-L- (pyrazol-1-yl-methyl) -acetanate of the formula and chloroacetanilide of the general formula where R is isopropyl, methoxymethyl or 1- as the active ingredient of the herbicidal agent. methoxyprop-2-yl; R is hydrogen or ETHYL) R is hydrogen, methyl or ethyl with a weight ratio of 1:11 equal to 1: 1-12. Herbicidal application forms are conventional emulsions, paste suspensions, powders, etc. They are prepared by well-known techniques. The content of active ingredients in these forms can range from 0.1 to 95% by weight, preferably from 0.5 to 90% by weight.
    The synergistic effect from the use of two-component mixtures is calculated by a known method. The following compounds are studied:
    A - 2-ChLOR-2, 6-dimethyl-N- (pyrazod-1-ylmethyl-) acetanilide
    B - 2-HLOR-2, b-di-ethyl-N- (methoxymethyl) -acetanilide
    B is 2-ChLOR-2-ethyl-b-methyl-N- (1-methoxyprop-2-yl) acetanilide
    G - 2-chloro-N-isopropyl-acetanilide
    Example 1. Plastic flower pots with a content of 300 cm were used as culture vessels. Clay sand with approximately 1.5% humus was used as a substrate. Seeds of experimental plants, according to table 1, divided by species, are sown flat. Immediately thereafter, during the pre-shoot treatment, the active principles are brought to the surface of the earth. Separate active principles and mixtures of them are suspended or emulsified in water and sprayed with fine distribution nozzles. After application of the means, the vessels are subjected to easy irrigation in order to promote germination and growth and at the same time activate chemical active principles. The vessels are then covered with transparent plastic caps before the plants germinate. The covering ensures uniform germination of the experimental plants because the chemical active principles do not interfere with this. The experiments were carried out in a greenhouse, and for those who prefer pacfe-; The scientific research institutes provide warmer zones, where the temperature is from 25 to 40 ° C and for plants that prefer climate, from 15 to 30 ° C. The test period is 4 to 6 weeks. During this time, plants are picked up and their reactions resulting from the treatment are evaluated.
    PRI mme R 2. Conducted experiments on small areas with clay sand (pH 6) and humus content from 1 to 1.5%. Application before shoot is carried out directly no later than 3 days after seeding. Cultivated plants are sown in rows. Weed flora of different species composition corresponds to natural flore. Using a motor driven mounted on a self-propelled sprayer chassis, substances are introduced that are emulsified or suspended in water as a distribution medium. In the absence of precipitation, irrigation is used to ensure the germination and growth of beneficial plants and weeds. The duration of all experiments is a few weeks. In certain periods of time 5, an assessment is made.
    Tables 1, 2, and 3 show that the actual damage rates of unwanted plants actually exceed the theoretically expected ones. School grades include numbers from 0 to 100. At the same time, 0. means no damage or normal shoot. 100 - the absence of plant shoots or the complete destruction of at least the aerial parts of the shoots.
    The synergistic effect of this combination of active principles on undesired grasses and broad-leafed species significantly exceeds the purely additive effect of individual active principles. In particular, open field experiments show that the proposed mixtures are suitable for practical use in order to selectively control unwanted plants in crops of useful plants.
    The synergistic herbicidal action of the agent containing the active substances A + B, when used in pre-emergence in the greenhouse, is presented in table. one.
    The synergistic herbicidal action of the agent containing the active substances A + B, with pre-emergence application in the greenhouse, is given in Table. 2
