LEXINGTON, Ky. — Collar rot can be found in tobacco float beds each year in Kentucky, causing a great deal of concern when it makes its appearance. Severe losses to this disease tend to be rare but can occur if care is not taken to minimize risk of disease development and reduce spread after it appears.
This fact sheet, which was just revised, discusses symptoms, signs, cause, disease development, and disease management options. Color images are provided to aid in diagnosing this disease and differentiating it from other float bed problems.
Collar Rot in the Tobacco Float System (PPFS-AG-T-03) is available online.
