摘要
比较5%西维因粉剂不同施用量,9种不同药剂,及5%西维因粉剂在青杨楔天牛Saperda populnea L.成虫羽化不同时期林间薰杀青杨楔天牛成虫的防治效果。试验表明:5%西维因粉剂以10kg/hm2的施药量熏杀青杨楔天牛成虫效果最佳,校正死亡率97.96%;5%西维因粉剂林间熏杀效果最佳,与其他8种药剂差异极显著;青杨楔天牛成虫羽化盛末期次日和羽化盛末期后2天早晨防治,校正死亡率分别为98.06%,97.52%,为熏杀防治的最佳时机。
Efficiency comparative experiments among carbaryl 5%dustable powder（DP） at different dosage and among 9 pesticides against Saperda populnea L.were made,and control effect of carbaryl5%DP against S.populnea adults in different emergence periods in the field were compared.The result showed the control effect of carbaryl 5%DP at the dosage of 10 kg/hm2 was the best,the corrected mortality of S.populnea adults was 97.96%;among the 9 pesticides,the control effect of carbaryl 5%DP was the best in the field and the difference was very significant;the optimum control time was in the mornings of the 2nd and 3rd days in the end of emergence peak,the corrected mortality were 98.06%and 97.52%respectively.
