Process for obtaining a FENILSULFONILGUANIDINA DERIVATIVE substituted herbicidal composition derived from SULFONILISOTIOUREIA phenyl-substituted benzenesulfonyl isothiocyanate substituted DIMENTIL-N- (substituted phenylsulfonyl) CARBONIMIDODITIOATO alkali metal salt of an N- (substituted phenylsulfonyl) CARBONIMIDODITIOATE

摘要

Herbicidally active novel substituted phenylsulfonyl guanidines of the formula IMAGE in which R1 is a phenyl or phenoxy group, each of R2 and R3 is a lower alkyl or lower alkoxy group, and R4 is a hydrogen atom, a lower alkyl group or a lower alkoxy group, and novel intermediates therefor.
