THESIS ON MANGO ANTHRACNOSE

Please provide a name for this query: The effect of anthracnose on the market prices of mango fruits in four major markets in Southwestern Nigeria. A significant reduction in the price of mango was found associated with anthracnose-infected fruits in all the major markets surveyed. The assessment of the effect of anthracnose on yield conducted indicated that trees treated with fungicides had higher mean fruit yield than untreated trees. Pusa Pratibha behaved moderately resistant with PDI Two mango tree branches randomly selected at the upper canopy were sprayed with spore suspension of Colletotrichum gloeosporioides using hand sprayer.

Fruits retained at harvest were counted and anthracnose infection was assessed as a product of the difference in number of fruits retained in treatment from control using the following formula:. They were then described and classified based on conidia and colony morphology as described by Dugan and Mordue In vitro evaluation of nine plant extracts revealed that leaf water extract of A.

Pathogen manyo also differed in exhibiting activity of pectin degrading enzymes PG, PMEwhich corresponds to the lesion size produced by respective isolates on mango fruit being highest in mango isolate I4.

Executive Summary, March,pp: It also increased the level of total phenolic contents and activity of peroxidase, polyphenol oxidase and phenylalanine ammonia lyase manto to the maximum extent.

From the result of the investigation, it was evident that Colletotrichum gloeosporioides was responsible for anthracnose qnthracnose in mango and was prevalent in all the study areas. Samples of symptomatic leaves, panicles and fruits of mango were, collected from mango orchards and home gardens in Ayetoro, Ibadan, Ogbomosho anthacnose Lagos and taken to the laboratory.

A field survey was carried out in 12 administrative districts of Ghana in and to assess the disease incidence and severity. This result supports the reports of several workers implicating Colletotrichum gloeosporioides as the causal agent of anthracnose of mango Than et al. The total soluble solids and acidity content of infected fruits were measured as means of determining the effect of mangl disease on juice quality of the fruits.

In some panicles, all blossoms were completely dried up resulting in no fruit setting. Botany, Production and Uses, Litz, R.

Mango Mangifera indica L. Fruits produced from trees in those orchards are commonly found associated with anthracnose-infected fruits that rot so quickly soon after harvest.

Based on the findings of this study, mango grows abundantly in every part of Southwestern zone of Nigeria. The severity index of the disease on a scale of ranged from anhracnose to 3.

On leaves, observed symptoms were small dark brown spots that coalesce to form irregular lesions. Pure cultures obtained were identified by visual examinations and viewing under stereo and compound electronic microscopes. Close Go to Workspace.

Therefore, manto present investigation was undertaken with the 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 – Fruits anthracnoxe at harvest were counted and anthracnose infection was assessed as a product of the difference in number of fruits retained in treatment from control using the following formula: Two mango tree branches randomly selected at the upper canopy were sprayed with spore suspension of Colletotrichum gloeosporioides using hand sprayer.

The mean disease incidence and per cent disease index varied between Isolation was carried out in both the Nigeria Agricultural Quarantine Service and in International Institute of Tropical Agriculture, plant pathology laboratories. On panicles, symptom begins as minute anthracnowe spots usually beginning from the attachment end of the panicle to the tree stem progressing upward to the tip resulting in shriveled, blighted flowers and small fruits.
