摘　　要：本实验采用浸渍法测定了腐烂茎线虫英国种群对6种不同杀线剂的敏感性,所试6种药剂处理腐烂茎线虫1 h、2 h、24 h后均有一定灭杀或抑制作用。LS011、阿维菌素、噻唑膦、甲维盐、氟吡菌酰胺、异菌脲处理24 h的LC50分别4.540 9、6.622 9、 523.192 9、343.312 0、4 859.326 3、24 838.768 5μg/mL。LS011、阿维菌素、噻唑膦和甲维盐可以作为处理种球、种苗候选剂。Six nematicides were tested for the efficacy on a population of Ditylenchus destructor from United Kingdom with contact assays in laboratory. The results showed that the six nematicides had significant lethal effect to D. destructor after 1 h,2 h and 24 h respectively. The LC50 value of 24 h of LS011, abamectin, fosthiazate, adimensional salt, fluoropylamide and iprodione were 4.540 9,6.622 9,523.192 9, 343.312 0,4 859.326 3 and 24 838.768 5 μg/mL respectively. The results suggested that LS011 ,abamectin, fosthiazate and adimensional salt possess good research potential for bulb and seedling quarantine treatment to Ditylenchus destructor.
