SU1079163A3 - Herbecidal composition - Google Patents

Abstract

A herbicidal composition is provided which is characterized by the combination use as active ingredients of a thiocarbamate derivative of formula I: <IMAGE> wherein one of X and Y is a hydrogen and the other is a chlorine and 4- amino-3-methyl-6-phenyl-1,2,4-triazin-5(4H)-one of the formula: <IMAGE> Also provided is a process of inhibiting the growth of unwanted plants by applying the herbicidal composition to the plants or to the soil where the plants are grown.

with an equivalent of 500 l / ha. After 25 d after spraying, the weights of the test plants are measured and the growth inhibition calculated by it is calculated from it. Inhibition of growth,% weight of plants grown in the treated container. 100 weight plants grown in an unprocessed container The results obtained are presented in Table. 1. For comparison, the same tests were carried out in which the compounds used in the composition were used separately under the conditions indicated. The results are also presented in table. 1 Example 7. It illustrates the herbicidal activity of the composition against various weeds and its phytotoxicity with respect to beets during processing after germination. In each and polyethylene containers with an area of 2000 cm, filled with ground from the nursery, beets are grown (stage 1.5-2 leaves), chicken millet (stage 2-2.5 leaves), one-year meter (stage 1.5-2 leaves), water pepper (stage 1-2 of the sheet) and mar (stage 1.5-2 of the sheet). A wettable powder containing 40 parts of compound A and 20 parts of compounds C prepared according to example 2, or a wettable powder containing 40 hours, compounds A and 10 hours, compounds C prepared by example or a wettable powder, containing: 40 hours Compounds B and 20 parts of Compound C prepared according to Example 2 or a wettable powder containing 40 parts of Compounds B and 10 Compounds C prepared as described in Example 4 are dissolved in water to obtain concentrations of the active compounds that ensure proper ratios shown herbicide Activity to beets when about in tab. 2. The aqueous solutions (or aqueous dispersions) prepared in this way are uniformly sprayed on the stems and leaves of the sprouted plants at a deposition concentration of 500 l / ha. 20 days after spraying, the weight of the plants is measured, from which growth inhibition (%) is calculated according to the above form: The results are presented in Table. 2. Example 8. Illustrates the germicidal activity of the composition against the yellow bristle and the width of the seedlings during processing before and after germination. Seeds of test species are placed on the soil surface in a 2000 cm polyethylene container and sprinkled on top with a 0.5 cm thick layer of soil with a wettable powder containing 30 parts of compound A and 30 hours of compound C prepared in example 5, or wettable nopoiiiOK, containing 40 parts of compound A and 10 parts of compound C, prepared according to example 4, or a wettable powder, containing 30 hours of compound-. Neither B and 30 parts of Compound C prepared according to Example 5 or a wettable powder containing 40 hours, Compounds B and 10 parts of Compound C prepared as described in Example 4 is dissolved in water to obtain concentrations of the active compounds that ensure the active compounds listed in Table. 3 Prepared by the proposed method, aqueous solutions (or aqueous dispersions) are uniformly sprayed on the soil when tested before germination and on the stems and leaves of growing plants when tested after germination with a concentration of 500 l / ha. 20 days after treatment, the degree of inhibition of the plants is determined, as shown above.
