从吉林、黑龙江、北京、天津等地采集土样28份，经室内分离纯化后得到木霉菌(Trichoderma.spp.)菌株60个，以立枯丝核菌为供试病原菌，通过对峙培养筛选出1株对立枯丝核菌有强拮抗作用的木霉菌菌株，将其孢子悬液对茄苗不同时期进行人工接种测定其对立枯病的防效，结果表明：这株拮抗木霉菌对茄子苗期立枯病有明显的防治效果，子叶期防效达73.3%，真叶期防效达71.34%。

There were 28 samples of soil collected from Jilin，Heilongjiang，Beijing and Tianjin etc., and 60 strains of Trichoderma spp. w ere isolated.By antagonistical cultivation, we obtained one strain of Tric hoderma spp. of high antagonistical action to Rhizoctonia solain. We als o us ed suspender liquid of Trichoderma spores to control Rhizoctonia Wilt at dif ferent period of eggplant. The results show that effectiveness of Trichoderma spp．is 73.3% in period of cotyledon and 71.34% at true leaf period.
