摘　　要：60%百泰(吡唑醚菌酯.代森联)水分散粒剂是由巴斯夫公司研发生产的一种新型杀菌剂,为拓宽其适用范围,采用室内生物活性测定与田间防治试验相结合的方式,测定了其对荔枝的主要病害荔枝霜疫霉病的作用。试验结果表明,60%百泰对霜疫霉病菌有优良的抑菌效果,浓度为10μg/mL的抑菌效果达96.98%,EC50和EC90分别为0.752、3.417μg/mL;大田防治效果优良,在荔枝挂果期施药3次,60%百泰1 000倍对荔枝霜疫霉病的防效达到80%以上,与对照药剂25%凯润乳油3 000倍处理的防效相近,显著优于另一对照药剂70%品润干悬乳剂700倍处理的防效,建议在荔枝产区推广应用。60% Cabrio Top WG （Pyraclostrobin ＆ Metiram）is a new fungicide from BASF, which effect on Peronophythora litchii was determined in laboratory and fields. The results showed there was inhibitory efficiency of 96.98% to hyphal growth of P. litchii in 10μg/mL Cabrio Top medium. EC50 and EC90 were 0.752μg/mL and 3.417μg/mL respectively. Spraying 60% Cabrio Top WG （1：1 000） for three times at fruiting period gave a control effect more than 80% against P. litchii, which were almost same as 25% Cahrio EC（1：3 000） and much better than 70% Polyram DF（1：700）. It was suggested that 60% Cabrio Top WG was applied in the litchi production.
