Signs of damage
The first sign of powdery mildew on plants is pale yellow leaf spots. White powdery spots can form on both upper and lower leaf surfaces, and quickly expand into large blotches. The large blotches can cover entire leaf, petiole and stem surfaces. When powdery mildew infects the majority of the foliage, the plant weakens and the fruit ripens prematurely.
How to prevent
Control is possible with triadimefon and propiconazole. It is also possible with hexaconazole, myclobutanil, and penconazole.
Standard fungicides are an effective way to manage powdery mildew disease on plants. Spray programs of conventional fungicides are advised to begin when symptoms and early signs of powdery mildew are first noticed. Conventional fungicides should be applied on a regular basis for best results against the disease.
