chemicals

Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type) L.)
Descriptor: Damage
Description: Carbofuran can cause small, irregular, oval-shaped lesions to first appear on the bottom leaves and progress upwards, especially under dry conditions. The white-tan to brown-yellow lesions are first produced on the leaf margins, followed by numerous lesions between the veins on the entire leaf. With high chemical concentrations, the leaf edges may be cupped upwards or curled downwards and the leaves may be narrow or arrow-shaped. Stunted plants and premature flowering may also occur. Recommended rates and proper application methods may produce a mild flecking but rarely the severe symptoms. Other disorders such as weather fleck and other chemicals may produce similar symptoms.
