The results showed that kinds of traditional Chinese medicine extracts exhibited different impacts in inhibiting Astragalus root rot fungi. Analysis of variance results indicated that from the point of view of both the types and concentrations of extracts of two Chinese medicines,F.cnidii showed better performance in preventing and controlling Astragalus root rot fungi, Cnidium combat the effect of Astragalus root rot fungus is more obvious, with significant level, the highest inhibition rate 96.13%.
