Symptoms and Variety Response to Phomopsis Boll Dangle in Louisiana

Boyd Padgett, Patrick Colyer and P. R. Vernon


 
ABSTRACT

Phomopsis boll dangle (PBD), also know as phomopsis boll rot, atypical boll shed, cotton blossom-boll rot, and vascular cavitation, is a condition in which small bolls (thumbnail size) mummify and remain attached to the plant. Affected bolls are light brown to reddish-brown and a sunken lesion extends from the base of the boll along the peduncle. The epidemiology and full impact of this condition is not fully understood; therefore, research has been initiated to provide additional information about PBD.
