    This invention relates to chemical methods for controlling weeds and unwanted vegetation.
    The aim of the invention is to increase the efficiency of the method of controlling undesirable vegetation based on the use of diphenyl ether derivatives.
    8pcs 1 is a list of active substances.
    The active substances are used in the form of preparations which are prepared by dissolving them in acetone containing O, A wt.% Of alkylphenyl polyoxyethylene ether, and diluting with water to a certain concentration.
    Pre-emergence treatment.
    Seeds of experimental plants are sown in prepared soil (garden loam) and treated with its liquid form of active substances. Plants are grown in a greenhouse for 12 days and evaluate the herbicidal effect on a scale from 0 to 9.
    O - no damage;
    9- full plant death; 1-8 - intermediate values
    (1 point corresponds to about 10%).
    The results of the experiments are presented in table. 3, Compound numbers correspond to the numbers in the table. one.
    Post-harvest processing.
    Experimental plants grown under greenhouse conditions to a certain stage are treated with active substance preparations in two ways: by irrigating the soil under the plants and spraying the foliage of the plants. The evaluation of the herbicidal effect was carried out 12 days after spraying the foliage and 13 days after irrigating the soil. The rating scale is presented above. The results of the experiments are presented in table. 2 and 3.
    Post-harvest processing (comparative experience).
    Experienced plants grown in. A greenhouse, before a certain growth stage, is treated with preparations of experimental substances and, after a certain time after treatment (12-14 days), the herbicidal effect is evaluated. The evaluation is carried out using a computer program.
    This program analyzes the selectivity distribution model in which compounds were tested for various plants. The analysis assumes the same distribution of selectivity for all compounds, but at different levels of non-active7 2
    nosti. Accepted by the same selectivity distribution, the program calculates the factors of the compounds that indicate the activity of each compound relative to one of them, to which the activity is attributed, is 1. The compound factor is proportional to the dose of growth inhibition by 50%. In this way. The lower the compound factor, the more active the compound.
