Powdery mildew
This disease can rapidly cover leaves, causing reduced crop growth and premature defoliation. Subsequently, losses in fruit yield and quality (owing to sunburn) may occur. Repeated fungicide applications are often necessary to avoid economic damage owing to powdery mildew. Selection and rotation of effective fungicides is critical for controlling powdery mildew epidemics, especially in growing areas where fungicide resistance in the P. xanthii population has been reported
