o The invention relates to the use of organophosphorus compounds, i.e., i-jerbits, in particular the ester amides of the acid booth (hapoidapic) of the thiophosphate backdrops, the use of this chain of the ether of amide alkypus (hapoidapkip) of the thiophosphonic acid, known containing mono-type popigaphopenphenic radical, for example isophos (0-2.4 - dihporpenyl - N with isopropyls of chloromethyphosphonate), in order to find breeders, bakers are offered as an herbicide of ester amide alkyl (halogidopkyl) asp, and as a baker has breeders, asparagus, as the herbicide of alkyl amide (halogidopkyl) tetra bladders, is offered by drawing breeders, as well as drawing bladders, asparagens, as is the herbicide of alkyl ether and halo, alkyl and nitro, halo and nitro, of the general formula KtP-0 where R is alkyl with 1 to 4 carbon atoms or hapoidapkyl; normal or iso-alkyl with 1 to 4 carbon atoms; hydrogen, alkyp or halo; Y is a halogen or nitro group. In this case, Y and R at the same time can not be halogen. The gerbid activity of the compounds was carried out under laboratory conditions. Wheat, oats, millet, and radish, which were grown in cups, were used as test objects. The preparations were applied to the agar-agar in the form of an emulsion. The plants grown on a pure agar medium served as controls. The results of the experiments are given in step 5, O-2 - chlorine - 4 methylphenyl - N - second, butylamidochlorine tyl tiophosphonate, O - 2 - nitro - 4 chlorofest have the strongest herbicidal properties. . - N.- sec. Butylamidochlorme-. tylthiophosphonate, 0-2-nitrophenip-N isopropylamido-hydroxyphosphate, which, at a dose of 0, OOZ-O, OO8 kg / ha, suppresses root growth of monocotyledonous plants of the Compound, can be used in the form of various preparative forms.
