Description
Herbicide-resistant weed populations have increased because of continuous use of the same grass herbicides. Several collections of wild oat with resistance to ACCase and ALS herbicides have been documented in North Dakota, leaving limited options for control. Two field experiments were conducted to evaluate the efficacy of triallate to control wild oat and determine spring wheat cultivar tolerance to triallate. Injury was not observed until twice the field rate of triallate was applied. Two greenhouse experiments were conducted to characterize 56 suspected resistant wild oat samples and determine triallate efficacy. Wild oat samples were characterized into three subgroups. Triallate provided at least 92% control of all wild oat samples within each subgroup; therefore, integrating triallate back into North Dakota cropping systems is an option to control wild oat in cereal production.
