Abstract

To determine highly toxic and fast-acting pesticides to combat the pine wood nematode（Bursaphelenchus xylophilus），a toxicity test of 22 kinds of pesticide used against the pine wood nematode （PWN） was conducted using a PWN suspension liquid plus pesticide with a processing time of 1 h to determine a median lethal concentration（LC50） for each pesticide. Results showed that the LC50 after a 1 h treatment was best with emamectin （0.3 mgL－1） and worst with cartap （21.053 gL－1）. In addition，four kinds of pesticide revealed acute activity toward the pine wood nematode with an LC50 after 1 h treatment of：matrin （1.2 mgL－1），chlorfluazuron （2.5 mgL－1），deltamethrin （4.2 mgL－1），and abamectin （4.5 mgL－1）. This meant that emamectin and abamectin could quickly and efficiently kill PWN，and the selected pesticides with acute activity to PWN could be used to develop a trunk injection against pine wilt disease. ［Ch，1 fig. 3 tab. 25 ref.］
