The Government of Maharashtra established the Konkan Krishi Vidyapeeth, Dapoli, Maharashtra on the 18th May 1972 to impart education, conduct research on location specific problems and disseminate the improved crop production technologies amongst the farming community.
We obtained diseased Okra samples from Konkan Krishi Vidyapeeth, Dapoli from Dr. Mahendra Bhairamkar (Extension training officer, Dept. of extension education, College of Agriculture, Dapoli).
Okra, Abelmoschus esculentus , is herbaceous hairy annual plant of the mallow family (Malvaceae). It is native to the tropics of the Eastern Hemisphere and is widely cultivated or naturalized in the tropics and subtropics of the Western Hemisphere for its edible fruit. Only the tender unripe fruit is eaten and it contains large amount of mucilage (gelatinous substance).

Later, spores were observed and the structure indicated that the disease causing fungus could be Colletotrichum spp.

(Colletotrichum spp. spores under Foldscope)
Species of Colletotrichum produce spores in tiny, sunken, saucer-shaped fruiting bodies known as acervuli. Symptoms include sunken spots or lesions (blight) of various colours in leaves, stems, fruits, or flowers, and some infections form cankers on twigs and branches.
