Burley tobacco in Kentucky is affected by a stunt disease caused by a soilborne pathogen. Characteristic symptoms include stunting, delay in flowering, and reduced yield and quality. Plants are seldom killed, and transplant survival is little affected. The disease is usually more severe in some portions of fields than in others, and the result is uneven growth and maturity. Severely stunted plants frequently appear beside vigorous ones. Snap bean, lima bean, and corn were not affected by the pathogen, and tomato was less affected than tobacco. The pathogen was controlled by fumigation with methyl bromide-chloropicrin or ethylene dibromide-chloropicrin.
