摘要
根据香草兰白绢病的症状，病原菌的形态、培养性状和寄主范围，将该菌鉴定为齐整小菌核菌（Ｓｃｌｅｒｏｔｉｕｍｒｏｌｆｓｉｉ ｓａｃｃ）。菌核净药效试验结果表明，在室内，有效浓度等于或大于１００μｇ／ｍＬ可抑制病菌生长；苗期病害防治，有效浓度为５００μｇ／ｍＬ，防治效果达８９．７％。
A causal agent was isolated from vanilla (Vanilla planifoli) inflicted with vanilla southern blight and identified as sclerotium rolfsii sacc according to its symptoms, colony morphology, cultural characters and host ranges. The control efficiency test of the fungicide,dimethachlon, showed that the pathogen growth was inhibited when applied with this chemical at a rate of 100 mg/ml a.i. or more. The control percentage was upto 89.7 % when applied at a rate of 500 mg/ml a.i. at the nursery stage of vanilla.
