Cotton leafroll dwarf virus symptoms (IMAGE) American Phytopathological Society Caption Reported from six counties in coastal Alabama in 2017, cotton blue disease affected approximately 25% of the state's cotton crop and caused a 4% yield loss. The disease was reported again in 2018, affecting 3-100% of cotton fields in Alabama but causing only a 1% yield loss. Symptoms, which include slowed plant growth, loss of chlorophyll, and dwarfing of infected leaves, usually do not appear until last August after full bloom. To date, there are no recommended strategies for management of this disease.
