Herbicide compositions of extended soil life

摘要

The soil life of herbicidally active thiocarbamates is extended by employing in combination therewith certain organophosphorus compounds having the formula <IMAGE> in which R4 is selected from the group consisting of cyclohexyl and phenyl; R5 is selected from the group consisting of C1-C4 alkyl and C1-C4 alkoxy; and R6 is selected from the group consisting of C3-C6 alkoxy, diallylamino, and -NHR7 where R7 is C3-C8 alkoxyalkyl.
