摘要 为了筛选安全高效的茶褐蓑蛾防治药剂,选择5%高效氯氟氰菊酯微乳剂、苏云金杆菌8000IU/ul悬浮剂、0.3%苦参碱水剂、0.5%印楝素乳油进行田间药效试验。结果表明,4种杀虫剂在连续2次施药后对茶褐蓑蛾都有较好的防治效果,防效在88.34%~98.35%。其中,5%高效氯氟氰菊酯乳油防效最好,达到98.35%,其次为0.5%印楝素乳油,且二者防效没有显著性差异,生产中可以0.5%印楝素乳油替代5%高效氯氟氰菊酯乳油。 In order to select safe and efficient insecticides to Mahasena colona Sonan,5%Lambda-cyhalothrin ME,Bacillus thuringiensis8000IU/L CS,0.3%Matrine and0.5%AS Azadirachtin EC were selected for field efficacy trials.The results showed that the4insecticides had good control effect on Mahasena colona Sonan in2consecutive times after the application.The control effect is in88.34%~98.35%.Among them,5%Lambda-cyhalothrin ME control effect is best,can reach98.35%,followed by0.5%Azadirachtin EC,and the two control effect has no significant difference,so can use0.5%Azadirachtin EC instead of5%Lambda-cyhalothrin ME in production.
