MANGO ANTHRACNOSE THESIS

Department Florida Cooperative Extension Serv. The importance of having a technique that allows an efficient expression of symptoms of anthracnose is based on the early differentiation of cultivars and the optimization of genetic, material and financial resources. Por otro lado, el crecimiento de T. The pathogen was found to be highly susceptible to 8 different fungicides available on the Ghanaian market. Among ten culture media significantly maximum colony growth of C. Dried fruit and vegetables for urban and export market. Responses of fresh-cut products of four mango cultivars under two different storage conditions.

This pathogen spreads within tree canopies as water-borne conidia during rainfall, and causes symptoms on young flush leaves, flowers and fruit. Isolation was carried out in both the Nigeria Agricultural Quarantine Service and in International Institute of Tropical Agriculture, plant pathology laboratories. Reduction of anthracnose on ripened mango fruits by chemicals, fruit bagging, and postharvest treatments. Okigbo and Osuinde only reported the role of Colletotrichum gloeosporioides in fungal leaf spots of mango in Nigeria while the first report of this disease on mango fruits in Southwestern Nigeria was only recently, reported by Onyeani et al. It is an important fruit crop in most tropical regions of the world and most eaten in the developed countries Diedhiou et al. 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.

Glomerella cingulata Ploetz and Prakash, and C. Effect of horticultural practices on incidence of anthracnose on yield and quality of mango.

Characterisation of the casual agent of mango anthracnose dis..|INIS

Effect of fruit bagging, fruit position, cultivar and postharvest treatment on postharvest disease of mangoes. The core—shell structure was clearly observed in TEM micrographs. OnyeaniSamuel O. Chitosan and changes in gene expression during fruit-pathogen interaction at postharvest stage. Botany, Production and Uses, Litz, R. These fungal species affects fruit quality and causes significant pre-and post-harvest fruit losses, espe- cially during wet weather Prusky and Plumbey, ;Prusky, ; Arauz, ; Chrys, However, the orchards are not regularly attended to; given room to orchards over-grown with weeds.

All branches were then covered with sterile polyethylene bags for 24 h.

It causes leaf, blossom blight and tree die-back in the orchard and can subsequently give rise to rottened fruits during storage and thus poses several problems Arauz, ; Ploetz and Freeman, The experiment involved pre-harvest sprays of fungicides, bioagents and botanicals at three growth stages of mango fruit cv.

All bagging treatments increased the percentage of the skin area manto yellow colour at the eating soft stage.

In general, pooled data of two consecutive years and revealed better performance of fungicides over bioagents and botanicals in minimising anthracnose decay in storage and retaining quality of anthracnoss fruits.

In light of this research, small scale chili farmers will be able to lessen pesticide treadmill thereby escalating ecological safety and profitability. This result confirms Flores report on stem-end or soft-brown rot as a major problem anthhracnose storage and shelf life of mango fruits. Mango bacterial canker, or anthacnose black spot, is a major concern for the export market where high fruit quality is required.

Please use this identifier to cite or link to this item: Based on the findings of this study, mango grows abundantly in every part of Southwestern zone of Nigeria. The relative humidity was correlated with populations of Colletotrichum sp.

Chitosan is a natural, biodegradable, and nontoxic compound with fungicidal properties and it also induces defense mechanisms in fruit tissues during the postharvest period. Yunxie Wei Jinji Pu. The implication of these results is that, mango trees with anthracnose infection amthracnose fruiting are most likely to produce fewer fruits except treated with fungicides. Schists which were found to contain much of muscovite have higher gamma counts than quartzite which has little or no muscovite.

At 50 mg mL-1, the extract causes morphological changes by reducing the size of hyphae, which become shorter and more branched. At Jachh, five cultivars viz.

The study shows that the radiometric mapping anthrscnose Basement Complex rocks can help greatly in revealing the distribution of radioactive minerals and lithologic boundaries in the study area. This study involved the use of radiometric measurement in mapping Precambrian Basement crystalline rocks of Owo metropolis, southwestern Nigeria. We value your privacy. This model was used retrospectively to estimate infection levels in two field trials which had been established to compare pre- and post-harvest practices in the control of the disease.

Presence of Colletotrichum acutatum and Colletotrichum gloeosporioides on leatherleaf fern, key lime, papaya, star fruit and mango in Costa Rica and Florida United States. Of the 85 isolates obtained from mango, all 33 isolates from Florida were identified as C. The mechanisms of control and efficacy of Trichoderma harzianum strain DGA01 against anthracnose-causing pathogen Colletotrichum gloeosporioides in mango cv.

The instrument always measures the complete spectrum from which it evaluates the counts per second cps values readings were computed and radioactivity graphs plotted.

The data were collected ,ango placing the equipment at about 1.

Regarding the plant extracts group, Citrus sinensis kango C. DGA01 parasitised the pathogen by coiling its mycelia and spores on both artificial media and mango fruit surfaces.
