Symptoms
Description:
Houseburn is also known as pole rot, barn rot, pole sweat, shed burn, vein rot, and stem mold. Symptoms include white mold on midveins, odor of rotting tobacco, and partial decay caused by several species of fungi and bacteria. Freshly harvested tobacco is not highly susceptible, but damage may begin when the cure progresses through the yellowing stage and portions of the leaf begin to die. Injury occurs when microorganisms attack leaves that become moist during periods of high humidity lasting longer than 24 hours. Damage is measured in weight loss and lowered leaf quality and can range from mild to severe. Conditions which favor harvest of immature tobacco and prolonged leaf wetness in the barn will encourage houseburn
