Abstract:
New heterocyclically-substituted 4-amino-1,2,4-triazin-5-one compounds, herbicidal compositions containing them and their use as herbicides are disclosed.It is known that 1,2,4-triazionones, such as, for example, 4-amino-3-methyl-6-phenyl-1,2,4-triazine-5-one, can be used for combatting weeds, especially for selectively combatting weeds, from German Offenlegungsschrift (German Published Specification) 2,224,161. Their general herbicidal action is, however, not always entirely statisfactory, especially when low amounts and low concentrations are used.
Abstract:
Halogenated 4-trifluoromethyl-4'-nitro-diphenyl-ether compounds of the formula ##STR1## in which R is halogen or methylthio, andX is hydrogen or chlorine,Are outstandingly effective as herbicides, particularly as selective herbicides.
Abstract:
A herbicidal composition containing as active ingredients(1) 4-amino-6-tert.-butyl-3-methylthio-1,2,4-triazin-5-one of the formula ##STR1## and (2) 2,6-dichloro-4-trifluoromethyl-4'-cyano-diphenyl ether of the formula ##STR2## preferably in a weight ratio from about 1:0.05 to 1:10. The composition can be used as a total herbicide or, at suitable levels of application, in growing crops as a selective herbicide against particularly resistant weeds.
