Substituted N-(1-ethyl-4-pyrazolyl)triazoloazinesulfonamide compounds of formula (I) such as N-(1-ethyl-5-methyl-3-(trifluoromethyl)-4-pyrazolyl)-5-methoxy-7-methyl[1,2,4]triazolo[1,5-c]pyrimidine-2-sulfonamide and N-(1-ethyl-5-methyl-3-(trifluoromethyl)-4-pyrazolyl)-5-methoxy-7-methyl[1,2,4]triazolo[1,5-a]-pyridine-2-sulfonamide, were prepared and found to possess selective herbicidal utility. The compounds are especially useful for the pre-emergence control of grassy weeds in soybeans. |
