frenching

Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type) L.)
Descriptor: Damage
Description: Frenching is caused by a toxin produced by a nonpathogenic soil bacterium (Bacillus cereus). Yellowing begins along the edge of young leaves and may eventually include all the area between the veins which remain green. Plants are stunted and develop a large number of long, narrow leaves and suckers. Frenching normally occurs in small areas of the field, especially in poorly drained, high pH soils during cool, wet weather.
