Abstract

Studies were established in 1988, 1989, and 1990 at two locations in Missouri to study the influence of fall tillage and herbicides on carryover of several residual soybean herbicides to grass and legume forage crops. Chlorimuron, clomazone, imazaquin, imazethpyr, and metribuzin plus chlorimuron were applied at their registered and 2X-registered rates in soybeans. Forage crops were planted the following fall and spring after herbicide application and evaluated for carryover effects. Fall tillage did not influence the carryover potential of these herbicides. However, herbicides injured several of the rotational crops. This injury was crop species and herbicide specific.
