Substituted N-(1-ethyl-4-pyrazolyl)triazoloazinesulfonamide compounds, such as N-(1-ethyl-5-methyl-3-(trifluoromethyl)-4-pyrazoyl)-5-methoxy-7-methyl-\x9b1, 2,4!triazolo\x9b1,5-c!pyrimidine-2-sulfonamide and N-(1-ethyl-5-methyl-3-(trifluoromethyl)-4-pyrazolyl)-5-methoxy-7-methyl\x9b1, 2,4!triazolo\x9b1,5-a!pyridine-2-sulfonamide, were prepared and found to possess selective herbicidal utility. The compounds are especially useful for the preemergence control of grassy weeds in soybeans
