Occurrence and Prevalence of Foliar Diseases on Blueberry in Georgia

Fig. 4. Diseases that contributed most to foliar disease severity on blueberry leaf samples, based on a field survey in Georgia in summer and fall of 2002 (n = 52) and 2003 (n = 83). Numbers of samples are lower than in Fig. 3 because 42 samples were affected primarily by non-pathogenic leaf damage and/or no primary pathogen was associated with disease symptoms.
