How to cite this article: Several workers including Rawal and Sangchote implicated these three fungal species in earlier reports, to be the fungi responsible for postharvest diseases of mango associated with fruit rotting during ripening. Morphological and cultural studies indicated that these isolates varied in colony development uniform, concentric rings, irregular , colour white, grey, light- grey, orange, light-orange, yellowish-white and diameter 5. When unripe, the fruit is tart, crispy and somewhat dry just like the green apples Wijeratnam et al. Market survey carried out in four major markets in the study areas, revealed that anthracnose-infected fruits attracted low prices Table 3.

They were then described and classified based on conidia and colony morphology as described by Dugan and Mordue Assessment of effect of anthracnose infection on the yield of mango: In addition, mango fruiting in the zone usually coincides with rainy seasons and high humid conditions associated with high temperature s, which have been reported by other workers to favours infection and colonization of the crop by fungal pathogens and in turn predisposes mango production to serious fungal attack. Untreated trees retained least fruit mean of On the other hand, Botryodiplodia theobromae and Aspergillus niger showed rotting symptoms typical of soft brown rot and black mould rot on wounded fruits, respectively.

It was also to determine the effect of the disease on the juice quality of fruits and come up with appropriate control measures in the country.
