摘  要:
Trials of fenoxaprop-p-ethyl EW for control of Avena fatua were conducted in highland barley field.The result showed that the normal dosage of 69 g/L fenoxaprop-p-ethyl EW was 900~1 200 mL/hm2(effective dose was 62.1~82.8 g/hm2).It was sprayed on stems and leaves at 300 kg/hm2 during 3~5 leaves in highland barley.Its plant control effect was 81.2%~89.0%,and fresh control effect was 83.2%~90.8% after 40 days.It had good control effect on weeds and was safe to highland barley.After the application,the yield of highland barley increased by 3.5%~11.8%.
