Stueies on the Occurrence of Seedling Rot of Burley Tobacco Transplants Caused By Pyhium spp. and Its Control Measures in Field.
초록
Seedling rot occurred on burley tobacco at the early growing stage after transplanting was surveyed in the Chonbuk province, the main area for burley tobacco production, during the 3 crop years from 1986. The incidence of disease was about 0.6-0.7% every year and major causal organisms were Pythium spp. More diseased plants were observed in the fields in which tobacco planted with improved mulching system than in that with any other mulching system.
