Abstract: Tobacco root knot nematode is a most important soil-borne tobacco disease in China. In recent years, it has occurred seriously in southwest China, especially in Liangshan Prefecture of Sichuan Province. A field experiment was made to evaluate the effect of Genjingkang, a microbial agent, mixed with different organic fertilizers on the control of tobacco root-knot nematode disease.The results showed that this technology could control the occurrence of tobacco nematode disease and promote the growth of tobacco plants. A mixture of Genjingkang with pig excrement manure had the best effect for controlling the disease, the control efficiency of which was about 58.31%.The control efficiency of Genjingkang mixed with local manure was 51.88%.The above results are believed to be able to provide reference for the biological control of soil-borne tobacco diseases.
