THESIS ON MANGO ANTHRACNOSE

Anthracnose has been reported in many parts of the world where the climate is suitable for mango production to be the most important field and postharvest disease of the crop Sangeetha and Rawal, ; Chowdhury et al. Fungi pathogens associated with mango fruit anthracnose: On panicles, symptom begins as minute dark 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.

Owuru and Olufemi S. Isolation and identification of anthracnose pathogen: Tropical Fruits in Asia: Abstract This study investigated the etiology of mango fruit anthracnose, its effect on yield and market values in humid Southern Nigeria. At the laboratory, the infected mango parts were, cut into small pieces. Morphological and cultural studies indicated that these isolates varied in colony development uniform, concentric rings, irregular , colour white, grey, light- grey, orange, light-orange, yellowish-white and diameter 5. Stem-end rot of mangoes in Australia:

In most cases, symptoms were observed only on leaf edges while in some cases the mid-rib of the leaf was also affected. This result supports the reports of several workers implicating Colletotrichum gloeosporioides as the causal agent of anthracnose of mango Than et al. The mang were, dropped on sterile paper towels, allowed to dry before plating them onto Potato Dextrose Agar PDA and incubated for 5 days at room temperature.

The disease was found to cause shriveling of fruit panicles and blemishes on skin of fruits resulting in yield loss of 4. When viewed under the microscope, conidia were hyaline; anthracnnose celled and cylindrical with obtuse ends. In Nigeria, mango production is limited by both man-caused factors unmanned orchards and natural factors disease pathogens despite the large expanse of land dedicated to its production.

If orchards are free of weeds, there could be greater aeration within the orchards, which will in-turn, reduce temperature and increase sunlight penetration, which could reduce the relative humidity within the orchards.

Effect of anthracnose on market value of mango fruits: The susceptibility of the different strains of the pathogen to fungicides available in Ghana was assessed using PDA amended with the fungicides after which efficacy of fungicides was evaluated in the field.

On panicles, ajthracnose begins as minute dark 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. The dietary contribution of mango fruits in the diet of most people in the tropics rank above anthrscnose of citrus fruits. The results show that two different symptoms, a sunken dark lesion and cracked skins were observable in Ghana.

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.

Amongst 21 bio-control agents evaluated under in vitro conditions three namely T. Mango anthracnose was recorded to occur in moderate to severe form in different mango growing areas of thdsis Kangra, Mandi, Sirmour and Solan of Himachal Pradesh.

The Identification of Fungi: Symptoms of anthracnose disease: Furthermore, the result revealed that the disease was the cause of mango yield loss and of rendering marketable fruits worthless in Southwestern, Nigeria.

Trees treated with fungicide during fruiting retained mean fruit of Fungal leaf spot diseases of mango Mangifera indica L. Fruits retained at harvest manog 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:
