Two separate greenhouse experiments were conducted in the greenhouse of the Iranian Plant Protection Research Institute, Tehran, to compare the efficacy of some Acetyl CoA Carboxylase (ACCase) and Acetolactase Synthase (ALS) inhibiting herbicides in control of wild oat biotypes. In each experiment, populations were independently treated by 10 herbicides each in 12 replications. To evaluate the effects of treatments, different characteristics including percent damage as based upon EWRC scores within 15 and 30 days after spraying, percent survived plants after spraying relative to that before being sprayed, as well as percent dry and wet weights of individual plants, relative to control, were scrutinized. Results indicated that the biotypes of wild oat were best controlled by clodinafop propargyl, and among ALS inhibitors, iodosulfuron plus mesosulfuron plus mefen pyre sulfosulfuron+metsulforon could control biotypes of Avena ludoviciana. very effectively vs. semi-satisfactorily, respectively. Iodosulfuron plus mesosulfuron and sulfosulfuron plus metsulfuron could dramatically reduce the wet weight of individual plants as compared with control so that the plants were not damage inflicting any more.
