[Screening strains for Trichoderma spp. for strong antagonism against ginseng root pathogens and study on their biological characters].

Objective: To screen the Trichodenna spp. for strong antagonist against ginseng root pathogens.

Method: The biological characters of ten Trichoderma strains were compared by culturing on different media.

[Progress on the control of medicinal plants soil-borne disease by anti-microorganism].

Much success had been achieved in the following aspect: the filtration of anti-microorganism, the action mechanisms, the inhibitory action in the field and so on. Though the narrow object and the unstable effect really exist now, it still has a broad developing future for it's advantage in keeping ecological balance and in fitting the requirement of GAP.
