Abstract

In ginseng fields, Alternaria blight, caused by Alternaria panax, and anthracnose, caused by Colletotrichum gloeosporoides, have become serious problems in Korea, and control of these diseases relies mainly on intensive applications of fungicides. In an effort to develop an effective environmentally-friendly control system, we utilized preventative control approaches including rain shelter shading plates and the removal of dead plants, as well as a curative control approach, such as the application of microbial agents. In the presence of rain shelter shading plates, the occurrence of Alternaria blight and anthracnose decreased significantly compared to that seen with polyethylene shading nets. In addition, the eradication of dead ginseng plants, which harboured abundant spores of the pathogens, significantly reduced the incidence of both diseases. In fields with rain shelter shading plates and in which dead plants were eradicated, four applications of a bioformulated product containing chitinolytic bacterial strains in a simple medium containing chitin provided control similar in effect to that observed with the application of the fungicide under low disease pressure. The efficacy of the bioformulated product was decreased slightly under severe disease pressure. These findings indicate that integration of the three disease management measures might constitute a new effective and environmentally-friendly system for the control of Alternaria blight and anthracnose in Korean ginseng fields.
