Abstract: Tobacco bacterial wilt is one of the mostrepresentative and destructive soil-borne disease on tobacco plants in Dechang county of Sichuan province.In a field experiment conducted in Dechang,we evaluated the effects of Genjingkang,a microbiome,mixed with different organic fertilizers on the growth of tobacco plants and bacterial wilt. The results demonstrated that mixtures of Genjngkang with pig manure,local organic manure or cattle manure could control the occurrence of bacterial wilt disease and promote the growth of tobacco plants. The treatment of Genjingkang + pig manure gave the best result,itscontrol efficiency being as high as 83.33%. The highest control efficiency of the treatments Genjingkang + local organic manure and Genjingkang + cattle manure was 80.00%and 73.33%,respectively.
