Host: burley tobacco (Nicotiana tabacum (burley type)
Description: Small irregular, oval- shaped lesions with a white-tan to brown-yellow appear on the margins of the bottom leaves. The lesions may progress to involve the entire interveinal area of the leaf as well as move up the plant, especially under dry conditions. With high concentrations of the chemical, the leaf edges may cup upward or curl downward, and the leaves may be narrow and arrow shaped. Stunting of the plants and premature flowering may also occur. Injury symptoms may be similar to those of manganese toxicity or triazine herbicide damage. Recommended rates and proper application may produce a mild flecking but rarely causes serious injury.
