The sooty mould fungi present in sooty mass on the upper leaves of mango (Mangifera indica L.) were studied and identified. Altogether 18 species of sooty mould fungi belonging to 8 genera were found. The mealy bugs appeared first as white specks on the under surface of mango leaves and a causal connection between sooty moulds and mealy bugs on mango leaves have been explained. The blackening of the mango foliage was found due to the growth of sooty mould fungi. Its presence in the form of black spots and blemish on mango fruits reduce the value of mango fruits. Spraying of fungicide and insecticide separately on mango foliage reduced the incidence and spraying of the two together further decreased the level of incidence when applied at an early stage of the incidence of the disease. Repeated application of liquefied coal tar around the base of the stem was found cheap and effective than mineral oil mixed with starch for preventing the female mealy bugs from crawling and climbing on mango trees before flowering and formation of mango fruits.
