5种植物源杀虫剂防治烟蚜效果研究

摘要

In this paper,five botanical insecticides(3% matrine AS,0.2% Celastrus angulatus EC,0.3% neem EC,0.5% veratridine SLX,and 4% rotenone EC) were conducted against Myzus persicae(Sulzer) on tobacco through field trails.The results showed that 3% matrine AS and 0.2% Celastrus angulatus EC had significant effects on M.persicae with the control efficacy over 90% at 20 days after the treatment.The two botanical insecticides were recommended against M.persicae on tobacco in nonpollution or organic fields.%选用5种不同的植物源杀虫剂3%苦参碱水剂,0.2%苦皮藤素乳油,0.3%印楝素乳油,0.5%藜芦碱可溶性液剂,4%鱼藤酮乳油对烟蚜进行田间防治试验。结果表明,3%苦参碱水剂和0.2%苦皮藤素乳油对烟蚜防效皆达到90%以上,药效期可持续20 d。因此,3%苦参碱水剂和0.2%苦皮藤素乳油这两种植物源杀虫剂可作为无公害烟叶和有机烟叶生产中防治烟蚜的推荐药剂。
