Abstract

Greenhouse and field experiments were conducted to determine the effectiveness of dichlormid, R-29148, CGA-92194, flurazole, naphthalic anhydride, and MON-5500 as herbicide antidotes for triallate in wheat and to determine triallate antagonism by seed-applied fungicides and insecticides. Seed treatment of MON-5500 at 0.063% wt/wt was the most effective antidote for triallate in wheat in both greenhouse and field. Dichlormid and R-29148 at 0.5% wt/wt were more effective as antidotes for triallate in wheat than either CGA-92194 or naphthalic anhydride. Flurazole, as a seed treatment, did not reduce triallate injury to wheat Dichlormid or R-29148 at 2.2 kg ai ha–1 applied broadcast to soil and incorporated reduced injury to wheat from triallate at 1.1 kg ai ha–1 and also reduced injury to oats from 0.3 kg ha–1 triallate. Seed treatments of carboxin at 0.2% wt/wt or imazalil at 0.008% wt/wt antagonized triallate and decreased injury to wheat from triallate at 0.6 kg ha–1. Maneb plus lindane or mancozeb treatment of wheat seed increased injury from triallate.
