Abstract

Two 5-yr experiments in a winter wheat-grain sorghum rotation were conducted near Hesston, KS, to evaluate selected foliage-applied herbicides to control honeyvine milkweed in the fall after wheat harvest. Herbicides that suppressed honeyvine milkweed stem populations 9 months after treatment included glyphosate, glyphosate plus dicamba, glyphosate plus 2,4-D, picloram, and four combinations of picloram plus 2,4-D. Honeyvine milkweed had regrown sufficiently by 24 months after herbicide application to require retreatment. Stem populations were suppressed following repeat treatments. Herbicide treatments increased yields of grain sorghum planted 9 months later but did not increase yields of winter wheat planted 13 months or longer after herbicide application.
