木霉防治西洋参立枯病研究

Studies on the Preventive Action of Trichoderma spp. Against Rhizoctonia Damping-off of American Ginseng (Panax quinquefolium )

拮抗作用测定中，木霉对西洋参立枯病菌有极强的拮抗作用。温室及田间试验表明，木霉对西洋参立枯病防治效果在60％以上，优于常用农药。

Trichoderma spp.showed strong antagonistic action against Rhizoctonia solani in screening tests. In green house and field experiments, its effect in the prevention of rhizoctonia damping off of Panax quinquefolium was over 60%, which is superior than other conventional fungicides.
