摘要:
New (trifluoromethylphenoxy)-phenylureas of the formula: ##STR1## wherein R is hydrogen or methyl andn and m, which may be identical or different, are each 0, 1, 2, 3 or 4, but only n and m may be 0 if the trifluoromethyl group is in the 3-positionAnd have strong herbicidal properties.
摘要:
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.
摘要:
The invention provides new 4-amino-5-thione-1,2,4-triazine (4,5-H) of the formula ##STR1## in which R is alkyl of up to 8 carbon atoms, cycloalkyl of from 5 to 7 carbon atoms, cycloalkenyl of from 5 to 7 carbon atoms, phenyl, which can optionally be mono-substituted or polysubstituted by halogen, or alkoxyalkyl of from 1 to 4 carbon atoms per alkyl and alkoxy moiety, andR' is hydrogen or alkyl of up to 4 carbon atoms;Which are outstandingly effective as herbicides, particularly as selective herbicides.
