摘要
草地贪夜蛾是2019年新侵入我国的世界性重大农业害虫,主要为害玉米和甘蔗等作物。为筛选防治草地贪夜蛾的安全高效药剂,设计并开展此试验。试验结果表明每666.7 m216000 IU/mg苏云金杆菌可湿性粉剂100 g+5%阿维菌素乳油50 mL、16000 IU/mg苏云金杆菌可湿性粉剂100 g+3%甲氨基阿维菌素苯甲酸盐微乳剂30 mL和6%氯虫苯甲酰胺·阿维菌素悬浮剂50 mL的速效性和持效性最好,5%阿维菌素乳油50 mL、3%甲氨基阿维菌素苯甲酸盐微乳剂30 mL和6%乙基多杀菌素悬浮剂30 mL的速效性和持效性较好,是防治玉米草地贪夜蛾的优选应急用药措施。
Spodoptera frugiperda,with its first invasion into China in January and main infection in maize,is a serious agricultural pest in the world.Field efficacy trials were devised and carried out to explore the control efficacy,technical skills and safety aspects of 11 kinds of insecticide against fall armyworm on maize.Results showed that the treatment of Bacillus thuringgiensis+Abamectin,Bacillus thuringgiensis+emamectin benzoate,chlorantraniliprole·Abamectin,Abamectin,emamectin benzoate and spinetoram were the first choice for the emergency of fall armyworm on maize.
