Abstract

In preemergence application of six different substituted urea herbicides on coriander (Coriandrum sativum L.) and tomato (Lycopersicum esculentum Mill.), the monohalogenated compounds were more effective in the destruction of the plants than their dihalogenated counterparts. The relative difference in effectiveness was much greater in the resistant coriander which appears to take up less dihalogenated than monohalogenated herbicide. In postemergence application, the dihalogenated herbicides generally were slightly more toxic than their monohalogenated counterparts.
