目前,松材线虫对松树的危害仍很严重,而空中喷洒对人畜低毒的有机磷杀虫剂杀螟松,是最有效的防治方法。但是,考虑到使用农药可能产生直接影响及残留药剂引起第二次影响,本文仅就后者叙述我们进行的试验。 At present, the damage caused by pine wood nematode to pine is still very serious. However, aerial spraying of organophosphate insecticide fenitrothion, which is low toxicity to human and livestock, is the most effective control method. However, considering the possible direct effects of the use of pesticides and the second impact of the residual agents, we only describe the latter with respect to the tests we conducted.
