Abstract
Abstract Herbicidal compositions in the form of synergistic combinations of either 3-methylmercapto-4-amino-6-isopropyl-1,2,4-triazin-5one or 3-methylmercapto-4-amino-6-tert.-butyl-1,2,4-triazin-5-one with either or both of N''-(3,4-dichlorophenyl)-N,N-dimethyl-urea and 3-amino-1,2,4-triazole, which are individually known compounds, which combinations possess synergistic herbicidal properties especially for the control of weeds.
