To screen the Trichodenna spp. for strong antagonist against ginseng root pathogens.
The biological characters of ten Trichoderma strains were compared by culturing on different media. And their antagonistic activity against Phytophthora cactorum, Cylindrocarpon destructans and Rhizoctonia solani were measured on PDA.
Tv04-2 and Th3080 showed a good growth on soil solution medium and PDA, and also showed high inhibitory efficacy to the three pathogens. The two Trichoderma strains showed different growth rate under light conditions and pH. Trichoderma strains were sensitive to most fungicides used in ginseng root disease controlling, however Tv04-2 was not sensitive to the fungicide Junchong Jueba.
筛选对人参根病原菌具有强拮抗作用的木霉菌株。
通过在不同培养基上培养，比较10株木霉菌株的生物学特性。并在PDA上测定它们对恶疫霉、毁灭柱孢和立枯丝核菌的拮抗活性。
Tv04 - 2和Th3080在土壤溶液培养基和PDA上生长良好，对三种病原菌也表现出高抑制效果。这两株木霉菌株在光照条件和pH值下生长速率不同。木霉菌株对人参根病防治中使用的大多数杀菌剂敏感，然而Tv04 - 2对杀菌剂菌虫绝霸不敏感。
