摘　　要：研究明确了北沙参锈病病原是一种缺锈孢型的、单主寄生锈菌;病菌以冬孢子在田间病残体上越冬,夏孢子不断侵染导致锈病流行;通过室内和田间药剂筛选,明确了多菌灵和代森锌是防治北沙参锈病的有效药剂,粉锈宁对北沙参锈病无效;防治北沙参锈病应采取农业防治与化学防治相结合的综合防治技术。This study shows that the pathogen causeing rust on Glehnia littoralis is a single-host Puccinia which can overwinter as teliospores on the plant remains in the field, and causes the epidemic of rust as through repeat infection of urediniospores. The laboratory and field tests indicated that carbendazim and zineb are fungicides effective in controlling the disease, while triadimefon is not effective. It was suggested that the integrated management technique combining cultivation management with chemical control should be applied to control the rust on Glehnia littoralis.
