After 24 h, one branch out of the two inoculated with Colletotrichum gloeosporioides spore suspension was treated with Ferbam Ferric dimethyldithiocarbamate at 4. Abstract This study investigated the etiology of mango fruit anthracnose, its effect on yield and market values in humid Southern Nigeria. The first observable phenomenon on the field was unmanned mango orchards with most trees found infected with anthracnose and fruits produced on those trees severely infected Fig. It has been reported that the fruits can be processed into dry mango, mango pickle, mango jelly, or can be eaten cooked Crane et al. Isolated colonies were, sub-cultured into fresh plates until pure cultures were obtained. Publication Year Publication Year.
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. This present study was initiated to further investigate the etiology of mango fruit anthracnose, its effect on yield and market values in mango-growing areas of the humid forest region of Southwestern, Nigeria. Market survey of anthracnose infected mango fruits were conducted in the year , and during mango seasons, respectively. May ; p; Available online at http: Host specificity of Colletotrichum gloeosporioides and Botryodiplodia theobromae isolates from mango, papaya and rambutan and their response to Trichoderma harzianum.

Pathogenicity test revealed that symptoms appeared after hours of incubation. Man and microbes in a continuous battle. Standard Search Advanced Search.
The athracnose disease incidence and per cent disease index varied between From the result of the investigation, it was evident that Colletotrichum gloeosporioides was responsible for anthracnose disease in mango and was prevalent in all the study areas.
A significant reduction in the price of mango was found associated with anthracnose-infected fruits in all the major markets surveyed.

Mango Growing in the Florida Home Landscape. The Identification of Fungi: The severity index of the disease on a scale of ranged from 0 to 3. The result of the investigation revealed that 96 out of fungal isolates recovered from symptomatic mango parts were Colletotrichum gloeosporioides based on their whitish orange colony, hyaline; single-celled and cylindrical appearance and pathogenicity test.
After 24 h, one branch out of the two inoculated with Colletotrichum gloeosporioides spore suspension was treated with Ferbam Ferric dimethyldithiocarbamate at 4. Trees treated with Ferbam ferric dimethyldithiocarbamate fortnightly from fruiting to maturity retained more fruits with mean fruit retention record of Other fungi isolates recovered were Alternaria alternataAlternaria tenuissimaAspergillus flavusAspergillus fumigatusAspergillus nidulansAspergillus nigerBipolaris hawaiiensisBotryodiplodia theobromaeCochliobolus nodulosusCurvularia lunataEntyloma species, Fusarium dimerumFusarium longipesFusarium verticillioides Table 1.
Some of the pure cultures obtained, on potato dextrose agar, had colonies that were whitish to dark grey with thick to sparse lawns of aerial mycelium when viewed from the top of Petri dishes while the revised view appeared greenish to thesia or dark brown centre bordered by creamy surrounding.
The protein profiling of eleven isolates of the mango anthracnose pathogen C. The unmanned orchards predispose the crop to severe anthracnose infection especially in the years when rains are heavy during the fruiting season. Fruits retained at harvest were counted and anthracnose oj was assessed as a product of the difference in number of fruits retained in treatment from control using the following formula:.

Amongst 21 bio-control agents evaluated under in vitro conditions three namely T. The study identified the fungus responsible for fruit anthracnose in mango, its effect on yield as well as on market value of fresh mango fruits in Southwest, Nigeria. Eleven isolates of Colletotrichum were isolated from mango and four isolates were isolated from apple, pomegranate and anthradnose.
Therefore, the present investigation was undertaken with tehsis objectives to record the prevalence of this disease; study the variability of causal agent Colletotrichum isolates and evolve effective disease management strategy through the use of fungicides, botanicals, bio-agents and their combinations as well host resistance during the year – In most cases, symptoms were observed only on leaf edges while in some cases the mid-rib of the leaf onn also affected.
Alteration of post harvest diseases of mango Mangifera indica through production practices and climatic factors. Out of these 15 species, the three most frequently occurring species included Colletotrichum gloeosporioidesBotryodiplodia theobromae and Aspergillus niger.
The disease has presently become a menace to both farmers and home gardeners in the Southwestern region of Nigeria making mango production no longer attractive in the area. Characterisation of the casual agent of mango anthracnose disease in Ghana. Reference Number Reference Number. In this study, field survey of fruit rot showed that soft-brown rot of mango was widely encountered.
