摘要
采用1.2%苦参碱·烟碱可溶性液剂、25%灭幼脲悬浮剂、20%除虫脲悬浮剂等3种农药不同浓度处理对马尾松毛虫进行防治试验,结果表明:1.2%苦参碱·烟碱可溶性液剂800倍液、1 200倍液、1 500倍液防治马尾松毛虫效果显著,防效均达到100%,可适用大面积生产性防治;25%灭幼脲悬浮剂1 500倍、2 000倍,以及20%除虫脲悬浮剂1 000倍的防效也较好,药后14d的防效在95%以上。
Experiments were conducted by using 1.2% matrine·nicotine soluble liquid＋25% vinblastine＋ 20%diflubenzuron were used to control Dendrolimus punctatus.Result shows that adopting 1.2% matrine·nicotine soluble liquid with 800 times,1 200 times and 1 500 times can obtain remarkable effect to prevent Pinus massoniana,the control effect reach 100%,which is applicable to large area of production control;the control effect of 1 500 2000times 25% vinblastine suspension agent and 1 000 times 20% diflubenzuron suspension agent is optimal;the control effect after 14 days is more than 95%.
