Trichoderma harzianum TUV-13对鱼腥草白绢病的防治及其促生长作用
Effects of Trichoderma harzianum TUV-13 on Growth ofHouttuynia cordata and Southern Blight Disease Caused by Sclemtium roifsii
摘要
Abstract
To study the effect of disease control and growth promoting ability of Trichoderma harzianum TUV-13 on Houttuynia cordata, authors applied the conidial preparation of the isolate marked with myclobutanil resistance to H. cordata by stem soaking and soil treatment, respectively. Results showed that stem soaking with TUV-13 promoted root and shoot germination more obviously. Soil treatment increased rhizome production more effectively. Control efficacy against southern blight disease caused by Sclerotium rolfsii of both treatments were more than 70% in the first year when TUV-13 was applied, and was up to 68.2% two years later. Re-isolation indicated that TUV-13 colonized the bulk soils efficiently, with population reaching 2.31×105 cfu.g-1, 289 times more than that of aboriginal Trichoderma spp..关键词
