Elsinoë mangiferae, common name Mango Scab, is also known Denticularia mangiferae or Sphaceloma mangiferae (anamorph). It is an ascomycete plant pathogen native to tropical regions and specific for survival on only one host, the mango.
The disease initially presents as small dark brown or gray spots on the underside of leaves or fruit. These spots enlarge and darken over time, developing a velvety or cracked texture in the center of the lesion.
Hot water treatment:
Dipping newly harvested fruits in hot water (53°C for 5-10 minutes) minimizes anthracnose and stem-end rot infestations. Anthracnose will be reduced by 83% and stem-end rot by 100%.
To facilitate heat water treatment, you need dipping tank, thermometer, and wire baskets. The water should have a uniform temperature within the tank to be effective. After dipping the fruits in hot water, dip them in tap water to about two hours or place them in a well ventilated room to cool down.
