Survival and spread of Powdery Mildew on Mango

  • The powdery mildew fungus overwinters in dormant buds. When conditions are favourable for the growth of the fungus in spring, spores are produced, released, and cause new infections. Secondary spread of the disease can occur if spores are produced in these new infections

Favourable conditions of Powdery Mildew on Mango

  • Rains or mists accompanied by cooler nights during flowering are congenial for the disease spread.

This gives us a lot to think about and to continue with the series will be taking a look at another disease in the next blog.
