Powdery mildew is a common fungal disease that affects vegetables, fruits, and ornamental crops, reducing yield and quality. A highly effective and eco-friendly biological solution is Ampelomyces quisqualis, a beneficial fungus that naturally attacks and destroys powdery mildew pathogens.
🌱 What is Ampelomyces quisqualis?
Ampelomyces quisqualis is a mycoparasitic fungus—meaning it parasitizes other fungi. It specifically targets powdery mildew fungi and destroys them from within.
It is widely used as a biofungicide in organic farming and Integrated Disease Management (IDM).
