ABSTRACT
<p><b>OBJECTIVE</b>To screen the Trichodenna spp. for strong antagonist against ginseng root pathogens.</p><p><b>METHOD</b>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.</p><p><b>RESULT AND CONCLUSION</b>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.</p>
