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%$\sim$73.56% against Alternaria blight in 2 times alternate spray of biofungicides and chemical fungicide at 14 days interval whereas the control efficiencies were 87.00%$\sim$89.42% in 2 times alternate spray of 3 different kinds of chemical fungicides at 14 days interval. In case of treatment combination the control efficiencies were 74.53%$\sim$87.23% in alternate spray of mixture of biofungicides and chemical fungicides at 28 days interval in all combinations except 2 kinds of combinations (Com-12 and Com-17). Therefore, the alternate application of the biofungicides and chemical fungicides or alternate application of mixture of biofungicides and chemical fungicides could reduce the amount of chemical fungicide about 75.00%$\sim$83.33%.

본 연구는 미생물제의 이용에 의한 농약잔류 및 안정성문제 확보, 농약 살포량 및 살포횟수를 줄이는 방법을 개발하기 위하여 실시하였다. 미생물제와 살균제를 2회씩 14일 간격으로 교호 살포한 처리구에서 인삼 점무늬병 방제가는 68.34%$\sim$73.56%이 었고, 살균제를 교호 살포한 처리구에서 방제가는 87.00%$\sim$89.42%이었다. 미생물제와 살균제를 28일 간격으로 3회 혼합 교호 살포한 처리구에서는 2종류의 처리구(Com-12, Com-17)를 제외하고는 방제가가 74.53%$\sim$87.23%로 조합에 따라 우수한 방제효과를 나타냈다. 이상과 같이 미생물제와 살균제를 교호 또는 혼합 교호 처리하면 75.00%$\sim$83.33%의 농약 감량효과를 나타낼 수 있다.
