Abstract |
Three kinds of disease occurring on ginseng leaves, such as grey mold, Alternaria blight, and anthracnose, started at the beginning of June, July, and August, respectively. The disease incidence was rapidly increased from the beginning of rainy season. To develop the control system with fungicides, 6 fungicides were selected and applied on ginseng at the indicated time. Calculating the control value by using the area under the disease progressing curve (AUDPC), the control activities of the supervised control system with fungicides were 61.7, 78.8 and 70.5% against grey mold, Alternaria blight, and anthracnose, respectively. The application of the mixture of carbendazim and diethofencarb on first of June was very important in control system with fungicides. If it was deleted in control system, control value was decreased against grey mold. In the case of Alternaria blight and anthracnose, the application of difenoconazole on July 18, and trifloxystrobin on August 7 were indispensible. If difenoconazole and trifloxystrobin were not applied on July 18, and August 7, the control activities against Alternaria blight and anthracnose, respectively, were decreased to 28.9% and 44.4%. |
