摘　　要：560 g/L嘧菌.百菌清悬浮剂是防治荔枝霜疫霉病的新型杀菌剂。2005～2006年田间防治试验表明,在荔枝挂果期用嘧菌.百菌清1 000、800、600倍液喷药3次后,对转色期果实霜疫霉病的防效为71.65%～83.50%,对成熟期果实霜疫霉病的防效为74.54%～88.98%,对贮藏期果实霜疫霉病的防效为77.01%～90.54%,均显著优于对照药剂80%大生可湿性粉剂600倍液的防效。560 g/L嘧菌.百菌清悬浮剂已登记在荔枝上防治霜疫霉病,可在广东及邻近省份的荔枝产区推广应用。560 g/L Azoxystrobin ＆ Chlorothalonil SC is a new fungicide against Peronophthora litchi. During 2005 and 2006, the result of effect tests in field showed that 560 g/L Azoxystrobin ＆ Chlorothalonil SC used at 1：1 000,1：800 and 1：600 for 3 times gave a control effect of 71.65% to 83.50% in the colour-changing period of fruit, 74.54% to 88.98% in the mature period and 77.01% to 90.54% in the storage period of fruit, significantly better than the control effect of 80% Da sheng WP used at 1：600. 560 g/L Azoxystrobin ＆ Chlorothalonil SC has been registered in the Peronophthora litchii, and it is suggested to be applied in the litchi production in Guangdong and other adjacent provinces.
