Mango FAQ

Powdery mildew is a fungal disease that can affect young mango leaves, flowers, and small fruit. A whitish powdery coating on flower clusters is a useful clue, although damaged flowers can later turn brown and lose that obvious coating. Affected bloom may fail to set fruit. Confirm the diagnosis rather than assuming every white deposit is mildew, and use locally appropriate disease-management guidance instead of guessing at a spray or chemical rate.

Look for pale, powdery growth on susceptible flower parts, especially while panicles are still developing. Examine living tissue before the cluster becomes uniformly brown, and use close photographs that show both the coating and the affected flowers. Dust, dried spray deposits, and insect wax can look similar from a distance. A sample from the advancing affected area is more informative than a handful of fallen, weathered flowers.
