Abstract |
To reduce the amount of chemical fungicides and the number of spray for the control of Alternaria blight of ginseng, biofungicides were used in order to reduce the residue and ensure the safety of ginseng plants. The control efficiencies were 68.34%~73.56% against Alternaria blight in 2 times alternate spray of biofungicides and chemical fungicide at 14 days interval whereas the control efficiencies were 87.00%~89.42% in 2 times alternate spray of 3 different kinds of chemical fungicides at 14 days interval. In case of treatment combination the control efficiencies were 74.53%~87.23% in alternate spray of mixture of biofungicides and chemical fungicides at 28 days interval in all combinations except 2 kinds of combinations (Com-12 and Com-17). Therefore, the alternate application of the biofungicides and chemical fungicides or alternate application of mixture of biofungicides and chemical fungicides could reduce the amount of chemical fungicide about 75.00%~83.33%. |
