Abstract: Control efficacies of polysaccharide from Chrysanthemum indicum L. against Atractylodes macrocephala Koidz. soil-borne diseases were investigated. The test divided into two parts, pot experiment in greenhouse and field experiment. The results of pot experiment showed that control efficacies were 6.277%, 83.863% and 71.839% when treated with 0.2, 2 and 20 mg/mL of polysaccharide after 10 days, respectively. And field experiment results showed that control efficacies were 57.836%, 74.925% and 82.470% when treated with 0.4, 2 and 20 mg/mL of polysaccharide after 60 days, respectively. Especially, the control efficacies of 2 and 20 mg/mL of polysaccharide were significantly higher than the commonly used TPN. Moreover, polysaccharide from C. indicum could improve the yield of A. macrocephala in the field. The per unit yield of 0.4, 2 and 20 mg/mL of polysaccharide increased by 17.647%, 14.706% and 32.353% than pesticide treatment, respectively.

Key words: Atractylodes macrocephala, polysaccharide from Chrysanthemum indicum, control effect
