防治萝卜菜青虫生物农药筛选试验
Shanghai Vegetables（2017）
Abstract
为筛选出防治萝卜菜青虫高效低毒药剂,我们开展了短稳杆菌等几种低毒生物农药防治萝卜菜青虫的田间药效试验.试验结果表明,各参试药剂对萝卜生长无异常影响,安全性较高;100亿孢子/mL短稳杆菌悬浮剂800倍液62.5mL/667m2、0.5%苦参碱水剂500倍液100mL/667m2、50g/L氟啶脲乳油1250倍液40mL/667m2,在菜青虫低龄幼虫高峰期使用,药后3d和药后7d的校正防效均在90%以上;各参试药剂对小菜蛾有兼治效果,对蜘蛛、瓢虫等有益生物安全;经检测,各参试药剂处理萝卜农药残留均达标.
