Abstract:
Synergistic herbicide combinations comprising (a) compounds of the formula wherein R 1 is selected from the group consisting of lower alkyl having from 2 to 6 carbon atoms, haloalkyl, benzyl and substituted benzyl, phenethyl, pyridylmethyl, cycloalkyl having from 3 to 6 carbon atoms, and haloalkenyl having from 3 to 6 carbon atoms, and R 2 and R 3 are each independently selected from the group consisting of C 2 -C 6 alkyl, C 2 -C 6 alkenyl and C 3 -C 8 cycloalkyl, provided further that R 2 and R 3 can join with the nitrogen to which they are attached to form a 5 to 6 carbon ring structure, and (b) an herbicidally effective amount of an anilide having the formula
in which R 4 is hydrogen and lower alkyl containing from about 2 to 5 carbon atoms, R 5 is alkyl containing from 1 to 8 carbon atoms, cycloalkyl having from 3 to 6 carbon atoms, lower alkenyl containing from 3 to 4 carbon atoms, and R e is lower alkyl containing from 2 to 5 carbon atoms. ln a typical application, the herbicide compositions are applied to the soil in either pre- or post-emergence treatment, or are applied to the seeds of the crop plant in herbicidally effective concentrations.
Abstract:
A synergistic herbicidal composition with residual activity comprises cycloate (I) and cyanazine (II) in a weight ratio of about 2 : 1 to 4 : 1, plus preferably a thiocarbamate herbicide antidote.
Abstract:
Synergistic herbicidal activity is displayed by a composition comprising the following two components:
(a) a thiolcarbamate of the formula in which
R' is selected from ethyl, benzyl, and p-chlorobenzyl, and when R' is ethyl, R 2 and R 3 are independently selected from C 1 -C 6 alkyl and C 5 -C 7 cycloalkyl, and when R' is benzyl or p-chlorobenzyl, R 2 and R 3 are independently selected from C 1 -C 5 alkyl, or conjointly form C 5 -C 7 alkylene; and (b) a phenylcarbamoyloxycarbanilate of the formula in which R 4 is C,-C, alkyl; and R 5 is selected from hydrogen and C 1 -C 4 alkyl.
The compositions may contain an inert carrier or diluent and optionally other active ingredients. They are applied post-emergence.

Abstract:
A mixture of the herbicides napropamide and butam has been found to exhibit synergistic results, particularly in pre-emergence surface application or pre-plant incorporation, and for controlling weeds in the presence of a rapeseed crop.
Abstract:
Synergistic herbicidal activity is displayed by compositions comprising a mixture of an alkyl 1-hexamethyleneiminecarbothiolate of the formula: and 1,1,1-trifluoro-N-[2-methyl-4-(phenylsulfonyl)-phenyl]-methanesulfonamide, at a weight ratio of 0.1:1 to 10:1. The compositions may include an inert carrier and, optionally, other active ingredients. Such compositions can be applied to a locus to control undesirable vegetation.
