Abstract:

Control effect of Derby, pinoxaden and isoproturon was investigated in barley field weeds of Jianghuai region. The results showed that, the effect of Derby was better for broadleaf weeds and pinoxaden was better for grass weeds in barley field weeds. Chemical control by the does 150 mL/hm2 of Derby 58 g/L SC plus 1200 mL/hm2 of pinoxaden 5% EC was the best. At 60 days after, correction control effect and fresh weight inhibition rate were 98.58% and 98.77%. Furthermore, it was safety and could be used as pre-emergence herbicides for extensive in barley field of Jianghuai region.
