Measures to control Powdery Mildew disease in Apple crop

It is a fungal disease that affects a wide range of plants, both indoor and outdoors. Powdery mildew covers the leaves of the apple tree with a white powdery growth, which reduces the amount of sunlight that can reach the leaves. This can reduce the tree's ability to photosynthesize. Powdery mildew can damage flower buds, which can reduce the number of apples that the tree produces. Powdery mildew can also affect the size and quality of the apples that are produced. Infected apples may be smaller, misshapen, and have blemishes on the skin.
