MANGO ANTHRACNOSE THESIS
Amongst the tested 75 EOs, four EOs showed remarkably higher antifungal activities. Out of these 15 species, the three most frequently occurring species included Colletotrichum gloeosporioides , Botryodiplodia theobromae and Aspergillus niger. Latent infections by plant pathogenic fungi in the field are the main reason of postharvest disease development during transit and storage. Present information regarding the Fusarium equiseti damage to citrus leaves can be used help identify the occurrence of pathogenic fungi in citrus fruit plantations. It is known to cause anthracnose in many crop plants, which ultimately leads to significant yield loss. The fungus was, identified to be Colletotrichum gloeosporioides Fig. Efficiency in vitro of five chemical fungicides, three plant extracts and three biocontrol products were evaluated by their inhibition of mycelial growth percentage and inhibition of fungal biomass percentage, for Colletotrichum gloeosporioides strain 52 and Colletotrichum acutatum strain
The severity index of the disease on a scale of ranged from 0 thesjs 3. There were significant differences in fruit yield among treated and untreated mango trees in the different mango-growing areas Table 2. Isolated colonies were, sub-cultured into fresh plates until pure cultures were obtained.

The purpose of this study was to identify Colletotrichum species associated with mango in different parts of Guangxi and examine their pathogenicity on leaves and fruits of mango in vitro. In the experiment with G. Therefore, the present investigation was undertaken with the objectives to record the prevalence of this disease; study the variability aanthracnose 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 – Molecular phylogenetic analysis of DNA sequences clustered 10 isolates of Colletotrichum into two clades i.
In most cases, blemished fruit failed to meet the required standard of choice and causes the economic loss in the global markets Arauz, This model was compared with a similarly derived model anthtacnose work in Australia; it appeared that the Philippine isolates of C. Evaluating effect of hot water treatment on development of anthracnose and quality of mango fruit is imperative.
Postharvest losses of fresh mango fruits are reported to be more than half of its production in some of the developing countries. A comparative study has been made of carbohydrates, proteins and amino acids in the bark of juvenile and mature mango plants Mangifera indica L.
Apparent infection rate of cv. These strains show mycelial growth at 2. It is concluded that attention should be given to develop effective strategy to control mango postharvest diseases and more focus should be given to stem end rot.
All fungicides reduced the severity of subsequent postharvest anthracnose, although none of the treatments reduced disease incidence. A moderate level of blossom blight developed in this orchard. Characterisation of the casual agent of mango anthracnose disease in Ghana. The epidemiology of the anthracnose pathogen of mango, Colletotrichum gloeosporioides, anthtacnose studied over two growing seasons in the Philippines.
Fresh mango fruits from the country hardly make it to the international market due to anthracnose infection. Guangxi itself has over 86, ha of mango production. The present chapter outlines the nutritional profiles, health benefits and industrial applications of mango and guava.
The effect of bagging of mango Mangifera indica fruit was evaluated in order to improve fruit quality of late maturing cultivars. Mango anthracnose was recorded to occur in moderate to severe form in different mango growing areas of districts Kangra, Mandi, Sirmour and Solan of Himachal Pradesh.
In advanced stages of the disease, the fungus produces acervuli, and orange to salmon pink masses of conidia appear on infected areas of the peel Arauz, Effect of anthracnose on the yield of mango in different mango-growing areas: A laccase gene LAC1, homologous to C.
Regarding the plant extracts group, Citrus sinensis and C. Chilli anthracnose disease caused by Colletotrichum species. El agente causal, Colletotrichum spp. Capsici in Southern Ethiopia.
This work comprised the isolation, anthracnosse and pathogenic assay from citrus fruit plantations Citrus nobilisTegal Wangi, Jember, Jawa Timur, Indonesia with 34 mold isolates obtained. Flowers show small brown lesions on the primary and secondary axis that result in a blight of the panicle Prusky, The study clearly showed the association of availability of phosphorus with floral induction.
Anthracnose disease of mango caused by Colletotrichum gloeosporioides var. Effect of anthracnose on market value of mango fruits:
