Screening and Safety Evaluation of Herbicides for Forage Sorghum and Silage Corn Strip Intercropping
The herbicidal effects and safety of 40%mesosulfuron-methyl suspension concentrate(MSC),48%quizalofop-p-ethyl aqueous solution(QZE)and 25%quinclorac suspension concentrate(QUI)single agent and compound for strip intercropping of forage sorghum and silage corn were evaluated.The results showed that MSC,QZE and QUI all showed good safety to the intercropped forage sorghum and silage corn.The compound of 40%MSC 540 g·hm-2 + 48%QZE 450 mL·hm-2 + 25%QUI 630 g·hm-2 showed the best herbicidal effect.When it was sprayed at the 3～4 leaf stage of forage sorghum,the herbicidal effect could reach 93.64%on the total weeds in the field after 15-day spraying and 92.80%after 30-day spraying.
