METHOD OF STABILIZATION OF ACTIVE SUBSTANCE IN SUSPENDED-EMULSIFIED HERBICIDE CONCENTRATE Russian patent published in 2001 - IPC

FIELD: organic chemistry, herbicides, agriculture. SUBSTANCE: invention relates to agents used for control of dicotyledonous weeds in cereal plantings. Method involves the use of the suspended-emulsified concentrate containing 2,4-dichlorophenoxyacetic acid C₇-C₉-esters, substituted sulfonylurea and solvent. Substituted sulfonylurea is adsorbed preliminary on the charge surface consisting of stabilizing agent, disperser, carrier or vehicle in the following ratio of components, wt.-%: 2,4- dichlorophenoxyacetic acid C₇-C₉-esters, 65-75; 3-(4-methyl-6-methoxy-1,3,5-triazinyl)-2)-1-(2- chlorophenylsulfonyl)-urea or 3-(4-methyl-6-methoxy-1,3,5-triazinyl-2)-1-[2-(2-chloroethoxy)- phenylsulfonyl] -urea or 3-(4-methyl-6-methoxy-1,3,5-triazinyl-2)-1-(2,5-dimethyl-phenylsulfonyl)-urea, 0.4-0.6; emulsifying agent, 15-20; stabilizing agent, 1.3-1.5; disperser, 3.0- 4.0; carrier, 3.0-4.0; vehicle, 0.1-0.3 and solvent, the balance. EFFECT: enhanced herbicide activity of suspended-emulsified concentrate. 2 tbl, 12 ex
