Significant differences were noted among 24 pecan cultivars being rated for susceptibility to fungal leaf scorch (FLS). Leaf samples were collected 20 September and complete mineral analyses were made. Correlation coefficients were determined for mineral content and FLS index. Significant negative γ values were obtained for FLS index when correlated with N, P, and Mn; and significant positive γ value for Ca content. Data indicate a need for additional research on fertility levels, mineral content, and reaction to FLS.
