Tobacco Streak Virus
Host: burley tobacco (Nicotiana tabacum (burley type)
Description: Streak in burley tobacco follows a typical pattern wherein vigorously growing plants suddenly develop a severe necrotic streaking of the bud leaves and stalk. The stalk is marked by a depressed dark area, and the midveins of the leaves have dead streaks in them. The leaves curl downward, are distorted, wilted, and usually chlorotic. When death of the affected plant seems imminent, growth resumes from the bud with resulting leaves appearing normal except for occasional faint mottling. Leaves damaged early are permanently dwarfed and exhibit numerous necrotic areas. The virus is common in sweet clover and is presumably moved to tobacco by an insect, probably by thrips.
