herbicides (general)

Host: burley tobacco (Nicotiana tabacum (burley type) L.)
Descriptor: Damage
Description: Exposure of tobacco to contact herbicides such as paraquat and dinoseb causes white lesions on leaves and stems. The lesions turn brown and may fall out, leaving holes in the leaf. Low levels of exposure produce distinct individual lesions. At higher exposure levels, the lesions combine, causing the leaves to yellow and areas between the veins to die and fall out. If the plant does not die from the exposure, later growth will be normal. Weather fleck, contact injury by other herbicides, and some types of chemicals produce similar symptoms.
