Identification Symptoms

  • The characteristic symptom of the disease is the white superficial powdery fungal growth on leaves, stalks of panicles, flowers and young fruits.
  • The affected flowers and fruits drop pre-maturely reducing the crop load considerably or might even prevent the fruit set.
  • The fungus parasitizes young tissues of all parts of the inflorescence, leaves and fruits.
  • Young leaves are attacked on both the sides but it is more conspicuous on the grower surface. Often these patches coalesce and occupy larger areas turning into purplish brown in colour
