What is Powdery Mildew, and Why is it Harmful to Your Plants?
Powdery mildew is a fungal disease that affects various plants, including vegetables, fruits, ornamentals, and trees. It is caused by a number of different fungal species and is characterized by a white, powdery coating on the leaves and stems of plants.
It is often found in areas with high humidity and can spread quickly in warm, damp environments. Powdery mildew can stunt the growth of plants, cause leaves to yellow and curl, and reduce the quality and yield of fruits or vegetables. It can also make plants more susceptible to other diseases.
