The optimum conditions for the fungi attack form during late summer, and that is why you will see these happening attacks way too common during this time.
During summer, the RH is very high, giving a good signal for white powdery mildew to attack. Strictly note that the fungi may happen anytime during the growing season of the plants, although late summer is the optimum period.
spores are usually blown by the mighty wind, giving birth to secondary infections. Secondary infections happen on new fruits, leaves, and shoots. Sometimes even when the shoot grows, fruits and leaves continue to get infected.
This infestation starts at night when the temperature is around 65 to 80 degrees Fahrenheit. The humidity during this period is about 70 per cent. It is a good time for this grayish-white fungus to quickly attack the leaf surfaces.
This infection usually starts from the underside and then appears on the upper part of the leaves. Infected leaves will have a silver-gray powdery look, while the fruit will look reddish brown. This disease may lead to no fruit formation when it attacks the buds.
Is powdery mildew apple tree contagious to other plants? If this is the question in your mind, then the short answer is yes! This is a more significant concern as this attack is famous for its spreading abilities. It makes the growth of the plants susceptible to secondary infestation attacks.
When it comes to treating powdery mildew, cultural methods are often the best approach. while some may suggest using fertilizers as a treatment for this disease, this is not recommended as it hinders the growth of new tissues, particularly during summer.

While chemical fungicides have negative impacts on the environment and may lead to resistance in the fungal population, Trichoderma harzianum is an effective and safe treatment for white mold on orchard that can promote healthy plant growth and suppress fungal growth.
Neem oil is a natural oil derived from the neem tree, with antifungal properties controlling powdery mildew on apple trees. To use neem oil, mix one tablespoon of oil with one gallon of water and spray the solution onto the affected areas of the tree. Repeat every seven to fourteen days until the white mold is gone.
