Papaya (Carica papaya)

Disease occurs both in field and in storage conditions.
The spots on fruits first appear as brown superficial discolouration of the skin which develops into circular, slightly sunken areas and 1 to 3 cm in diameter.
Gradually the lesions coalesce and sparse mycelia growth appears on the margins of the spots.
Under humid conditions, an encrustation of salmon pink spores is released.
Infection at early stages of fruit results in mummification and deformation.

Diseased leaves, twigs, gall midge infected leaves and fruits, should be collected and burnt.
Covering the fruits on trees, 15 days prior to harvest with news or brown paper bags.
