The invention relates to chemical means of protecting plants, namely to a herbicidal agent containing an active substance from among the derivatives of thiol-carbamic acid and auxiliary components.
Herbicidal agents containing derivatives of thiol-carbamic acid as active substances are known, for example, an agent containing the active substance 5-methyl-M- {3chlorfeiyl) thiolcarbamate and auxiliary components - sodium salt diis shod ilnaphthalene-gsb-sulfonic acid and sodium ligninsulpha-acid;
However, the known tools are not sufficiently effective for certain types of weeds.
The purpose of the Invention is to enhance the herbicidal activity of the agent based on a thiol-carbamic acid derivative.
The goal is achieved by the fact that the herbali. the product contains as a derivative of thiolcar
baminic
acid compound of general formula
Methods for preparing compounds of the formula J are based on the reaction of the corresponding aryl isocyanates with methyl 5-mercaptan or on the interaction of the corresponding anilines with thiomethyl chloroformate
PRI mery. Experimental plants were grown in plastic pots with a capacity of 300 cm on a clay-sandy culture substrate with 1.5% humus. Seeds of experimental plants were shallow and for post-emergence treatment they were grown to a height of 3–10 cm. Some vtsdy experimental plants were grown in separate vessels, and then the shoots were transplanted into the above-mentioned pots. The plants were treated by spraying with an aqueous solution of a herbicidal agent containing 20 parts by weight. active thing, 3 weight.h. diisobutyl-naphthalene-o-sulfonic acid sodium salt, 17 parts by weight sodium salt lignin5 5 O

sulfonic acids and 60 weight.h. silica gel. Experiments were performed in a greenhouse at 15 (depending on the type of plants) for 3-6 weeks. During this time, the plants were cared for and recorded for their treatment with a herbicide. Results were evaluated according to a scale from 0 to 100, with O being meaning no damage or normal shoot ,. and 100 0 lack of shoot, complete damage to at least sprouts located above the surface.
