MANGO ANTHRACNOSE THESIS

The severity index and infection coefficients increased in function of time. Keitt fruit influences fruit quality and mineral composition. Plant extracts containing bio-active compounds with antimicrobial properties could be a good possible solution to deal with the fungi. These results were obtained 8 days after inoculation. This study was focused on pathological characterization of predominant postharvest diseases such as stem end rot of mango Mangifera indica caused by Lasiodiplodia theobromae, and evaluation of bio-control activity by different plant extracts. Anales Jardin Botanico Madrid,

Gro and Sin monosporic strains were isolated from leaves, flowers, fruits and branches with anthracnose symptoms from commercial mango orchards located in Guerrero and Sinaloa states, Mexico. Sprays of mg a. Effect of anthracnose on the yield of mango in different mango-growing areas: Botryodiplodia stem end rot of mango and its control. The presence of siloxane crosslinks in the shell was confirmed by FT-IR spectra.

DGA01 parasitised the pathogen by coiling its mycelia and spores on both artificial media and mango fruit surfaces. The coper fungicides alone or in combination with other fungicides are used worldwide for diseases control Anhhracnose, According to Wills et al, the increment of the respiration mahgo stimulates increased mango weight loss as well as a high con- centration of ethylene, which causes softening, colour changes, and production of aroma volatiles.

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.

Carotenoid compounds are considered potent antioxidants with beneficial effects on human health Gallicchio et al. Isolated colonies were, sub-cultured into fresh plates until pure cultures were obtained.

Mango Anthracnose: Economic Impact and Current Options For Integrated Managaement

The minimum, optimum and maximum temperatures for C. Presence of Colletotrichum acutatum and Colletotrichum gloeosporioides on leatherleaf fern, key lime, papaya, star fruit and mango in Costa Rica and Florida United States. It has been recognized by national and international organizations with innovation awards.

The trees were de-blossomed by pruning the stems 5 cm below the base of distal panicles and exposed to 3 temperature regimesand in 8 treatments under a h photopeAxillary flower induction was greatest on the mango trees subjected to the low-temperature treatment thexis for 2 or more weeks. All isolates from leatherleaf fern 25 isolates and Key lime 25 isolates were identified as C.

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

This result supports the reports of several workers implicating Colletotrichum gloeosporioides as the causal agent of anthracnose of mango Than et al. Out of 60 isolates obtained from starfruit, 3 isolates from Costa Rica were C. Anthracnose disease of mango caused by Colletotrichum gloeosporioides var. 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.

In the field, infections can take place from mangoo initiation until fruits are mature Daquioag and Quimio, The overall incidences of SER were Among the bacterial isolates tested, P.

Untreated trees retained least fruit mean of Effect of anthracnose on market value of mango fruits: The aim of this study was to evaluate changes in carotenoids and total phenolics of persimmon astringent fruits, cv. We evaluated the ability of fungicides to eradicate latent anthracnose infections and to protect young mango fruit from new infections in laboratory and field experiments in Thailand.

The lowest incidence was recorded for the treatment mangl which the fruits were submerged in NEW with 60 mg liter—1 active chlorine for anthrqcnose min.

We are sincerely grateful to God and to all the people who contributed in one way or the other to make this study a success. On immature fruits, symptom was not noticeable but on green-matured fruits, the symptom observed was dark brown to black spots of about 0.

Infection studies with leaves and fruit incubated at different temperatures and humidities led to the derivation of a logistic regression model of the percentage of conidia forming appressoria.

Gro and Sin monosporic strains were isolated from leaves, flowers, fruits and branches with anthracnose symptoms from commercial mango orchards located in Guerrero and Sinaloa states, Mexico. The most common fungal isolates were these three species: A second orchard, situated in an area less favourable to disease, was also monitored during 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.

Results of this study indicated that anthracnose in Tahiti lime and tamarillo are caused by Colletotrichun acutatum whereas symptoms on mango were induced by mangoo species Colletotrichum gloeosporioides, which was also founnd in few citrus samples.

Corn meal broth medium produced maximum dry anhracnose weight of test pathogen followed by Waksman’s and Czapek’s broth. A field survey was carried out in 12 administrative districts of Ghana in and to assess the disease incidence and severity. Most fruit species possess the natural ability to resist fungal invasion when they are unripe Adikaram,
