Evaluation of the efficacy and safety of 12 herbicides against broadleaf weeds in peanut-cotton intercropping fields
In order to screen efficient and safe herbicides in peanut-cotton intercropping fields,the greenhouse biological activity tests were carried out to evaluate the control effects of 12 herbicides against six common broadleaf weeds,and their safeties to peanut and cotton.The results showed that oxadiazon 120 g/L EC,oxyfluorfen 240 g/L EC,flumioxazin 51％WG,prometryn 40％WP,and pendimethalin 330 g/L EC had good control effects on six broadleaf weeds at the recommended dose in the field.Pyroxasulfone 40％SC had excellent control effects on the tested weeds,the selectivity index were more than 2 for cotton and 6 types of weed.Thifensulfuron-methyl 25％WP,cloransulam-methyl 84％WG,fluoroglycofen-ethyl 20％EC had poor safety to cotton.
