摘　　要： 采用组织分离法对张家口市辣椒疫病病原菌进行了分离培养和形态观察,并利用菌丝生长速率法测定了7种杀菌剂对该菌的毒力。结果表明:经鉴定该菌为辣椒疫霉(Phytophthoracapsici Leonian);抑菌效果最好的是64%噁霜.锰锌可湿性粉剂500倍液,抑制率为71.38%;其次是嘧菌.百菌清悬浮剂500倍液和72%霜脲.锰锌可湿性粉剂400倍液,抑制率分别为66.89%和62.35%;抑制效果最差的是66.6%霜霉威盐酸盐水剂500倍液,抑制率为22.67%。 Through tissue isolation,pathogen of pepper blight in Zhangjiakou were isolated,cultured and morphological observation,and toxicity tests of seven fungicides to P.capsici Leonian were carried out using inhibiting mycelium growth rate in laboratory.The results showed that the isolate was identified as Phytophthora capsici Leonian,and the effect of 64% evil cream·mancozeb WP was the best with control effect of 71.38%,followed by Azoxystrobin·chlorothalonil suspending agent and 72% Cream urea·mancozeb WP with control effect 66.89% and 62.35% respectively,66.6% Propamocarb hydrochloride aqueous solution was the worst with control effect 22.67%.
