Chemical control of wild oats in wheat with di-allate and barban

Abstract

Results are presented from experiments in which di-allate and barban were used for wild oat control in wheat at 21 sites in the Wimmera and Northern Districts of Victoria. Both chemicals significantly reduced the wild oat densities at most sites but where direct comparisons were made di-allate was more effective than barban. Wheat yield response to applied herbicide was obtained in 17 of the 21 experiments. However, the yield response to barban application showed greater variation than the yield response to di-allate application. Barban was more effective, at all tested rates, n the Wimmera than it was-in the Northern District.
