Powdery Mildew

Powdery mildew is a serious disease of okra, beans, southern peas, squash, cucumbers, muskmelons, and pumpkins in almost all the areas of the country. The disease is caused by the fungus Erysiphe cichoracearum DC ex Merat [Sphaerotheca fuliginea (Schlecht ex Fr.) Poll.)]. Other species of Erysiphe like E. polygoni causes powdery mildew in beans, southern peas, and English peas and Sphaerotheca macularis affects strawberries. Okra or Bhindi or Lady’s finger (Abelmoschus esculentus Moench) is an important vegetable crop. Most of the okra cultivars are susceptible to powdery mildew disease, and depending upon the age of the plant at the time of infection, yield losses range between 17 and 86.6%. The disease is favored by low temperature (11-28°C) and dry weather conditions and early infection has more effect on the plant growth and yield than late infection. Effective control of the disease is possible with fungicidal applications and the recommended fungicides are benomyl (0.1%), wettable sulfur (0.2, 0.3 and 0.5%).
