Abstract

It's crucial to control Alternaria blight and Anthracnose emerging mostly on ginseng leaves during the rainy season to increase the organic ginseng products. The purpose of this study is to investigate the efficay of lime-brodeaux spray on the ginseng leaves and evaluate the growth and yield of the ginseng, and the contents of ginsenoside and 70% ethanol extracts from 3-year-old ginseng variety, Cheonpoong. Lime-bordeaux sprayings were conducted in the ratio of 6-6 in June, 8-8 from July to September every 15 days. After June 10, the spraying have no effects on the growth leaf and stem, and there was no significant increase in chlorophyll contents. The ratio of intact leaf and root were distinctly increased because Alternaria blight and Anthracnose were decreased by spraying lime-bordeaux mixture. Root weight per plant and root yield were increased by 15%, and 62% in 3-year old ginseng, respectively, because the ratio of intact leaf and root were higher by using lime-bordeaux mixture. Furthermore, spraying of lime-bordeaux mixture is prone to increase the ratio of rusty root in ginseng. Spraying of lime-bordeaux mixture decreased both of the contents of ginsenoside and 70% ethanol extract by 13.7%, and 15.2% in 3-year-old ginseng, respectively.
