竹腔注射40%氧化乐果乳油防治两色绿刺蛾试验初报

Test on injection of 40% omethoate EC into bamboo cavity against Latoria bicolor

本文采用竹腔注射40%氧化乐果乳油防治两色绿刺蛾,结果表明,竹腔注射不同剂量的40%氧化乐果乳油防治两色绿刺蛾均有效果。注射剂量3～5 mL/株较剂量1～2 mL/株的防治效果好。竹腔注射3～5 mL/株40%氧化乐果乳油,施药5 d后,两色绿刺蛾虫口校正死亡率可达93.5%以上。

Bamboo cavity injection of 40% omethoate EC was used to control Latoria bicolor.The result showed that,different dosages of 40% omethoate EC injected in bamboo cavity were effective against L.bicolor.The injection dosage of 3~5mL per plant had better effect than the injection dosage of 1~2mL per plant.When the injection dosage of 40% omethoate EC was 3~5mL per plant,5 days after treatment the corrected mortality of L.bicolor reached above 93.5%.
