Abstract : Samples of infected mango leaves, twigs and fruits were collected from the experimental garden of the Horticulture Department, University of Agriculture, Faisalabad, Pakistan, in 1996-97. C. gloeosporioides [Glomerella cingulata] was isolated in high frequency from infected fruits. Pathogenicity tests revealed that infection only occurred in injured fruits. A number of fungicides, thiophanate-methyl (as Topsin M), mancozeb (as Dithane M-45), propineb (as Antracol), benomyl (as Benlate) copper hydroxide (as Nordox), hexaconazole (as Anvil), Darosal, fosetyl (as Aliette), fenarimol (as Rubigan), sulfur (as Thiovit) and penconazole (as Topas) were tested against G. cingulata. Thiophanate-methyl, mancozeb, propineb and benomyl were most effective in vitro against G. cingulata at all concentrations. The fungicides which were effective in vitro were also effective in vivo, with copper hydroxide also being effective.
