Weeds emerging on winter wheat and barley field at early spring are troublesome, even with pre-emergence application of herbicides such as butachlor, tribunil, etc. Searching the proper post-applicating herbicides to control those weeds, three herbicides; ioxynil, bromoxynil and MCPA were evaluated with weeding efficacies in barley field. Tank mixture of bromoxynil and MCPA was the most excellent in weeding efficacy, especially in higher mixing rate at early April application to the broad-leaf weeds, among others.
