Effect of Carfentrazone-ethyl on Non-grassy Weeds and Wheat Yield

摘要

Carfentrazone-ethyl against Chenopodium album, Melilotus alba, Melilotus indica, Lathyrus aphaca, Vicia saliva, Meditago denticulata and Rumex acetosella Its weed control efficiency at 20 g ha~(-1) ranged from 90,6 to 100% Carfentrazone at 20 and 25 gha~(-1) had better efficacy than 2, 4-D and was comparable with metsulfuron methyl Total weed dry matter production in 2, 4-D treated plots was higher than that of carfentrazone-ethyl at 15 and 25 g ha~(-1). The grain yields recorded with carfentrazone-ethyl at 15 and 25 g ha~(-1) and metsulfuron methyl at 4 g ha~(-1) were similar to weed-free treatment.
