Abstract：For a long time, root rot disease, caused by several soil inhabitated, has been one of the most important diseases on panax notoginseng planting. At present there are few measures to control this disease effectively. During the previous surveys, we found a pesticide agent from plant extracts (trade name: Xiandi No. 1), that was initially used in root knot nematodes controlling, had shown unexpected efficacy on preventing panax notoginseng from root rot disease. As the results, the effects of Xiandi No.1 on the control of panax notoginseng root rot disease were investigated by indoor antifungal tests and field plot experiments. The experimental results show that, by using of Xiandi No.1 in the field, the incidence of root rot disease decreased to 38.35%, and the relative control effect may up to 58.96%. Meanwhile, its indoor inhibition rate to Fusarium solani, the main pathogen of panax notoginseng root rot disease, reached to 63.12%. Compared to general chemical fungicides, this agent shows more environmental friendly and economical, as well as a competitive performance.
