杀灭松材线虫的高效药物筛选与毒性测定
Pesticide toxicity and selection for the pine wood nematode
摘要
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 mg·L-1) and worst with cartap (21.053 g·L-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 mg·L-1), chlorfluazuron (2.5 mg·L-1), deltamethrin (4.2 mg·L-1), and abamectin (4.5 mg·L-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.关键词
