摘要
为探索不同药剂对番茄潜叶蛾的防治效果,筛选出高效、低毒、低残留、环境友好型防治药剂,选用30%虫螨腈·虱螨脲悬浮剂等4种杀虫剂,开展了番茄潜叶蛾幼虫防治效果试验。结果表明:30%虫螨腈·虱螨脲悬浮剂、15%甲维盐·茚虫威悬浮剂、25%甲氧虫酰肼·茚虫威悬浮剂在施药后3d的虫口减退率均在90%以上,可有效防控番茄潜叶蛾幼虫。以30%虫螨腈·虱螨脲悬浮剂的防效最好,持效期最长,施药后7 d处理的虫口减退率可达93.2%。试验药剂均对番茄作物安全,可作为化学防控番茄潜叶蛾的轮换药剂使用。
In order to explore the control effect of different pesticides on tomato leaf miner and screen out high-efficiency,low toxici‐ty,low residue and environment-friendly pesticides,this study selected four pesticides such as 30%dinitrile and loudiurea suspension to carry out the control effect test of tomato leaf miner larvae.The results showed that 30%dinitrile·loudiurea suspension,15%methotrexate·indomethacin suspension and 25%methoxyhydrazide·indomethacin suspension all had a population decline rate of more than 90%three days after application,which could effectively control the larvae of tomato leaf miner.The control effect of 30%dinitrile·loudiurea suspension was the best,and its duration was the longest.The insect mouth decline rate of 7 days after appli‐cation could reach 93.2%.The tested chemicals are safe for tomato crops,and can be used as a rotation agent for chemical control of tomato leaf miner.
