INTERACTIONS OF DPX-PE350 WITH FLUAZIFOP-P, SETHOXYDIM, CLETHODIM, AND QUIZALOFOP-P

Interactions of fluazifop-P, sethoxydim, clethodim, and quizalofop-P w ith DPX-PE350 were evaluated. DPX-PE350 at 110 g ae ha-1 reduced contr ol of large crabgrass when mixed with all graminicides and control of broadleaf signalgrass when mixed with fluazifop-P or quizalofop-P. Inc reasing the mte of graminicide reduced or eliminated antagonism. Apply ing sethoxydim and DPX-PE350 sequentially eliminated antagonism on lar ge crabgrass. Control of seedling johnsongrass by the graminicides was not reduced by DPX-PE350. DPX-PE350 reduced control of rhizomatous jo hnsongrass by sethoxydim. Graminicides had no effect on entireleaf mor ningglory control with DPX-PE350.
