Nature of mango anthracnose in Ghana: Implications for the control of the disease
Abstract
Abstract
Mango anthracnose is a major disease hampering the production of quality fruits for export in Ghana. The nature of the disease and its spread were studied in 82 mango farms in the Greater Accra, Eastern, Volta, Ashanti, Brong Ahafo and Northern regions of Ghana in 2010 and 2011. Field visits were undertaken to mango farms, and the types of the disease symptoms and sources of inoculum were determined. A survey was also carried out to measure the disease incidence and severity at the preharvesting stage, whilst the incidence of the latent infection was also determined. Two types of symptoms were attributed to the disease. Leaves, dried panicles and mummified fruits were found to be the major sources of inoculum. The disease was not found in five of the districts surveyed. Comparatively, more of the disease was found at the postharvest stage than at the preharvest stage. The implications of the findings are discussed.
