昆虫病原线虫防治小白菜黄曲条跳甲的田间效果

Effects of Entomopathogenic Nematode on Controlling of Phyllotreta striolata in Brassica campestris ssp.chinensis Makino

为探索防治小白菜黄曲条跳甲的绿色防控方法,本试验比较了昆虫病原线虫、昆虫病原线虫混用化学农药及单用化学农药3种方式对小白菜黄曲条跳甲的田间效果试验。试验结果表明,每667 m^(2)采用昆虫病原线虫3亿尾防治效果好,可有效避免化学药剂安全间隔要求,确保叶菜质量安全。

In order to explore the green control methods of Phyllotreta striolata in Brassica campestris ssp.chinensis Makino,the field effects of three methods of entomopathogenic nematode,entomopathogenic nematode mixed with chemical pesticide and single chemical pesticide on P.striolata were compared.The results showed that control effect of 300 million entomopathogenic nematodes per 667 m^(2) was good,which could effectively avoid the safety interval requirement of chemical agents and ensure the quality and safety of leafy vegetables.
