Insect, Pest and Disease Control - Tobacco
Black root rot has been one of the most costly diseases of tobacco in Tennessee. This disease attacks tobacco either in the plant bed or in the field. It is a serious problem where tobacco is grown repeatedly in the same bed or field. Rarely does black root rot cause spectacular damage in any one field. It is important that growers be able to recognize black root rot and take the necessary control measures.
