Claims12
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 a chloroacetamide or a thiophenamine and the auxin transport inhibitor is present in an amount producing a potentiating effect in a weight ratio of the auxin transport inhibitor to said other herbicide from 1:50 to 5:1.
A method of potentiating the herbicidal effect of dimethenamid comprising combining dimethenamid with a potentiating effective amount of an auxin transport inhibitor of formula A ##STR6## wherein, X and Y represent independently, hydrogen, fluorine or chlorine and R is the group ##STR7## wherein M is hydrogen or a salt forming moiety and weight ratio of the auxin transport inhibitor to dimethenamid is from 1:50 to 5:1, to produce a herbicidally effective composition.
