摘要

It is composed of N - (2 - ethyl - 4 - pirazolil) triazoloazinasulfonamida replaced, such as n - (1 - 5 - methyl - ethyl - 3 - (trifluoromethyl) - 4 - pirazolilo - 5 - methoxy - 7 - methyl [1,2,4 triazolo [1],5 - C] - pyrimidine sulphonamide and N - (2 - ethyl - 4 - 1 - methyl - 3 - (trifluorome til) - 4 - pirazolil) - 5 - methoxy - 7 - methyl [1,2,4] triazolo [1,5-a] - pyridine - 2 - sulfonamide.These compounds are Selective herbicidal activity, which are especially useful in the control during the pre Emergency demalezas herbaceous in cu ltivos soy.Prepared by condensation of N - ethyl - 4 - (1 - aminopirazoles with detriazolazinsulfonilo compounds CHLORIDES.
