Effects of Nitralin and Chloroxuron Combination on Weeds and Soybeans

Abstract

Nitralin (4-(methylsulfonyl)-2,6-dinitro-N,N-dipropylaniline) controlled grasses and 3-[p-(p-chlorophenoxy)phenyl]-1,1-dimethylurea (chloroxuron) controlled broadleaf weeds in soybeans(Glycine max(L.) Merr.) as well singly as when combined. In 1 year out of 2, nitralin and chloroxuron in combination caused more plant injury than either herbicide alone. The combination of nitralin (0.56 or 0.84 kg/ha) with chloroxuron (1.68 kg/ha) reduced seed yields 37% from the value obtained with chloroxuron alone (1.68 kg/ha).
