哈栖木霉(Trichoderma harianum)是近年来国内外研究较多、应用较广的一种对植物土传病原真菌有极强寄生能力的真菌。自1970年美国学者Wells Bell和Jawarski从感病齐整小核菌(Sclerotium rolfsii)中分离到此菌、并用以有效地防治了一些由齐整小核菌引起的蔬菜白绢病以来,对这一真菌的研究就从未间断过。近十年来的大量试验表明,哈栖木霉除对蔬菜白绢病有极好的防治效果外,还对由齐整小核菌、丝核菌(Rhizoctonia solani)、疫霉(Phytop- Trichoderma harianum (Trichoderma harianum) is a kind of fungus with strong parasitism to plant soil-borne pathogenic fungi, which has been widely studied and widely used in recent years. Since 1970, when American scholar Wells Bell and Jawarski isolated the bacterium from the susceptible Sclerotium rolfsii and used to effectively control some of the disease caused by the genus Trichophyton sclerotiorum, this fungus The study never stopped. In recent years, a large number of experiments show that Trichoderma harzianum in addition to the excellent control effect on vegetable whitefly disease, but also on the whole genome of the same bacteria, Rhizoctonia solani, Phytopsis,
