Lime-bordeaux caused damage onleaf when it was sprayed on ginseng between April and early May. No difference was found in root growth by sprayinglime-bordeaux mixture between ratio 4-4 and 8-8 ratio in concentration. Plot of 6-6 raito and 8-8 ratio appeared to be sim-ilar efficacy compared to that of practical chemical control. However, the plot of 4-4 ratio showed lower than that of chem-ical control.Key Words : Panax ginseng, Lime-Bordeaux Mixture, Alternaria blight, Anthracnose
