Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type)
Description: Dry weather causes reduced leaf growth, along with wilting, yellowing, and subsequent "rimfire" or burning from the edges and between lateral veins of the lower leaves. Leaves tend to be more upright than normal, especially in the upper part of the stalk, giving the plant a "bunchy" appearance. Leaves become thicker than normal, and flowering is delayed. Leaves on older plants may develop whitish areas and take on a sunbaked appearance. Leaf maturity is delayed, and tobacco quality and yield may be greatly reduced. Symptoms may develop slowly as soil moisture is depleted. Plants on sandier portions of a field exhibit symptoms first.
