Claims10
A herbicidal composition comprising a herbicidally effective aggregate amount of an auxin transport inhibitor of the formula A ##STR4## wherein, X and Y represent independently, hydrogen, fluorine or chlorine, and R is the group ##STR5## wherein Z is hydrogen, fluorine or chlorine and M is hydrogen or a salt forming moiety and one other herbicide
- wherein the herbicide is dicamba and the auxin transport inhibitor is present in an amount producing a potentiating effect in a weight ratio of the auxin transport inhibitor to dicamba from 1:50 to 5:1.
A herbicidal composition comprising a herbicidally effective aggregate amount of an auxin transport inhibitor having the formula ##STR6## wherein, X and Y represent independently, hydrogen, fluorine or chlorine, and M is hydrogen or a salt forming moiety and one other herbicide wherein the herbicide is dicamba and the auxin transport inhibitor is present in an amount producing a potentiating effect and the weight ratio of the auxin transport inhibitor to dicamba herbicide is 1:50 to 5:1.
A method of potentiating the herbicidal effect of a dicamba comprising combining the dicamba with a potentiating effective amount of an auxin transport inhibitor of formula A ##STR7## wherein, X and Y represent independently, hydrogen, fluorine or chlorine, and R is the group ##STR8## wherein Z is hydrogen, fluorine or chlorine and M is hydrogen or a salt forming moiety and wherein the weight ratio of the auxin transport inhibitor to dicamba is 1:50 to 5:1, to produce a herbicidally effective composition.
