FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, in particular to the field of agrochemical compositions based on bentazone. Herbicidal composition includes, as an active compound, 3-(1-methylethyl)-1H-2,1,3-benzothiadiazine-4(3H)-one 2,2-dioxide (bentazone) and auxiliary substance. Bentazone is used in the form of an acid dissolved in an adjuvant, for which N,N-dimethylalkylamide is used at a mass ratio of 1:(0.2–10) %, respectively. As N,N-dimethylalkylamide, the following compounds can be used: N,N-dimethylformamide, N,N-dimethylacetamide, N,N-dimethylpentanamide, N,N-dimethylhexanamide and N,N-dimethyldecanamide.
EFFECT: proposed herbicidal composition provides for the production of bentazone in a finely dispersed state, which provides high biological activity, the composition has a high chemical stability during storage, stability of the working fluid during use and increased efficiency in the protection of leguminous crops.
