Herbicidal N- (4,6-substituted pyrimidin-2-yl)aminocarbonyl!- substituted fused pyrazole-3-sulfonamides

摘要

Pyrazole sulfonylureas are expected to show pre- and post- emergence herbicidal activity. Specifically preferred in this class of compounds is N- (4,6-dimethoxypyrimidin-2-yl)aminocarbonyl!-4,6-dihydro-2- methyl-4-oxo- 2H-f uro 3,4-c!pyrazole-3-sulfonamide.
