Abstract
The joint control of wild oats (A vena fatua) and ryegrass (Lolium rig idum) in mixture in a wheat crop using a single postemergence herbicid e, diclofop-methyl, was examined. The two weeds were found to have dif ferent competitive strengths against wheat and different degrees of se nsitivity to the herbicide. Response surfaces to different rates of he rbicide and different weed densities were estimated statistically and these functions were used to examine optimal control practices for dif ferent mixtures of the weeds.
