摘　　要：马兰茎腐病病原为丝核菌属立枯丝菌,该病多发生在低温、高湿季节(环境)。在浙江丽水地区,马兰地上茎发病时间一般在10月下旬至次年4月,地下茎发病时间在5月至10月初,并开展了多菌灵、百菌清、农用链霉素、注射用青霉素钠4种药物的田间防治试验,结果表明,利用多菌灵800倍液喷雾(连续3次、每次间隔6d)防治马兰茎腐病效果最好,有效率达到75.54%;百菌清防治效果次之,有效率为53.82%;农用链霉素和注射用青霉素钠防治效果极低,有效率仅为14.48%和11.96%。Field observation was carried out on occurrence regulation of stem rot of Kalimeris indica to find effective control to the disease in Lishiu,Zhejiang province,it occurs from October to April of the next year to the aerial stem, by from May to October to the underground stem.. Four pesticides were used for field control with 5 repeats, such as carbendazim, chlorothalonil, agricultural streptomycin and Benzylpenicillin Sodium for injection. The result showed that spraying 800-fold of carbendazim had the best result to control stem rot, with effectiveness of 75.54%.The next was chlorothalonil, with effectiveness of 53.82%, agricultural streptomycin and Benzylpenicillin Sodium for injection had very low effect, only 14.48% and 11.96%.
