While it’s easier to identify powdery mildew as this appears as gray or white powdery spots. This grows well in places with high humidity and dry climate. 

Although seldom fatal, it can rob nutrients and water if left on plants, leading to slower growth or withering.

Mildew affects not only the people but also their surroundings. Admittedly, it only grows on the surface of a material, so it doesn’t do severe damage.

Mildews would often develop in wet places around 24-48 hours, and then spores would be produced, leaving it traveling through the air.
