●● AVOIDING powdery mildew APPLES are among the many crops affected by powdery mildew, a fungal disease of the foliage, stems and occasionally flowers and fruit where a superficial fungal growth covers the plant’s surface.
Other fruits affected include blackcurrants, gooseberries and grapes.
Symptoms include white, powdery spreading patches of fungus on upper or lower leaf surfaces, flowers and fruit and the tissues sometimes become stunted or distorted.
Destroying fallen infected leaves in autumn will reduce the amount of infectious spores next spring.
Mulching and watering reduces water stress and helps make plants less prone to infection.
Promptly pruning out infected shoots will reduce subsequent infection.
