生物农药防治设施番茄根结线虫田间药效试验

摘要

We carried out the test to screen out suitable biological pesticides against root knot nematode for facility tomato. The results showed that, the four biological pesticides could control the occurrence of root knot nematode disease on greenhouse tomato in a certain extent, and the control efficiencies were 65.4%-89.7% 60 days after planting and 51.5%-83.5% after harvest respectively. The two biological pesticides 10% fosthiazate granules and Paecilomyces lilacinus granules had higher control efficiency and they could be widely used in the production of pollution-free vegetables.%通过试验筛选防治设施番茄根结线虫病的生物药剂。田间小区试验结果表明，4种生物农药处理均能在一定程度上控制大棚番茄根结线虫病的发生，定植后60 d 防治效果为65.4%~89.7%，收获时防治效果为51.5%~83.5%，其中以10%噻唑磷（福气多）颗粒剂和淡紫拟青霉颗粒剂效果较为明显，可在无公害蔬菜生产上推广应用。
