Abstract

Diclofop [2-[4-(2,4-dichlorophenoxy)phenoxy] propanoic acid] was evaluated to determine Italian ryegrass ( Lolium multiflorum Lam.) control and effect on yield of winter wheat ( Triticum aestivum L.). Diclofop applied at 0.5, 0.75, 1.0, and 1.5 kg/ha postemergence provided excellent control of ryegrass and resulted in significant yield increases of winter wheat. Diclofop was most effective when applied at the two- to three-leaf stage of Italian ryegrass growth. Postemergence applications of diclofop plus bentazon [3-isopropyi-1 H -2,1,3-benzothiadiazin-4(3 H )-one 2,2-dioxide] gave excellent control of ryegrass and significant increases in wheat yields.
