From the early 1,100 to 1,900 ginseng cultivation seemed to be practiced with management of the diseases which were, in general, referred to a "disaster" at that time. Farmers had individually developed their own methods to manage the disaster
with
a
try and error from generations to generations. It was not determined until 1909, however, that plant pathogens as a new concept was involved in the disaster and thirteen ginseng diseases were reported in Korea by Japanese plant pathologists. The
intensive researches have been carried out from 1978 when Korea Ginseng and Tobacco Research Institute was established. Among the ginseng diseased reported in ginseng growing countries. Alternaria panax. Botrytis sp. Cylindrocarpon destructans,
Colletotrichum gloeosporioides, Erwinia carotovora subsp. Carotovora, Pythium spp. Phytophthora cactorum, Sclerotinia sp. Sclerotium rolfsii, and root rot caused by Ditylenchus destructor have been observed in Korea and the appropriate control
methods
for the major diseases were developed. However, the other nine diseases reported by former researchers have not been confirmed for their pahogenicities and/or occurrences on ginseng yet.
