Caused by Lasiodiplodia theobromae, affects mechanically-injured areas on the stem or skin. Endophytes cause mango stem end rot 227 1. 2010). Flesh CaFig. 1C). Stem end rot Symptoms â A dark rot develops from the stem end as the fruit ripens after fruit harvest. And a dark brown to black rot begins at the stem end as a dark brown ring and the rot proceeds towards the other end. Stem end rot severity continued to decline with increased duration of bagging, but there was no consistent effect on anthracnose severity after 56 days. 2013). The isolates reproduced the symptoms on mango fruits in an inoculation test and were reisolated from the inoculated fruits. Eleven species of Botryosphaeriaceae were associated with mango stemâend rot in Malaysia. Stem canker Phoma sp. They were wrapped Stem end rot (Botryosphaeria spp., Lasiodiplodia theobromae and other fungi) is a soft, watery rot that develops from the stem end as fruit ripens after harvest. To the best of our knowledge, four species, namely L. mahajangana, B. ramosa , N. ribis and P. violaceum are the first recorded Botryosphaeriaceae fungi associated with stem end rot of mango. Mango post harvest diseases minimize fruit quality and cause losses. A number of fungi including Ladiodiplodia theobromea, Coletritricum gloeosporiodes and Fotogercis mangiferea cause the stem end rot disease in mango. THE Department of Science and Technology (DoST) said it launched a three-year project to find mango strains resistant to scab and stem-end rot diseases. The major causes of mango fruit losses are postharvest diseases, including fruit rot (stem-end rot) disease caused by Lasiodiplodia theobromae and anthracnose caused by Colletotrichum gloeosporioides [3,4]. This research aimed to develop and evaluate pre- and postharvest management strategies to reduce stem end rot (SER) incidence and extend saleable life of 'Carabao' mango fruits in Southern Philippines. Five branches consisting of stem, inflorescence and fruit (if present) were detached from each tree and transported intact to the laboratory. â¦ Since 1986, over 6,000 mangoes cv. To develop an optimal method for controlling post-harvest stem-end rot of mango, we examined to inactivate fungi on peduncle by using the dielectric barrier discharge (DBD) or the high-concentration ozone gas. nonwrapped) were stored for 16-21 days In Sri Lanka, Stem-end rot (SER) disease in At a site with a history of high stem end rot â¦ If mango seed weevil, bacterial black spot, stem end rot or red banded caterpillar are detected during a department export inspection Australian mango exports to Korea work plan Date published Current version number20/01 Small, superficial lesions can develop on fruit in the grove, but the disease usually is apparent only on fruit that is very overmature, hanging on dead Botryodiplodia theobromae, the causal organism of stem end rot disease of mango was studied.Isolates of B.theobromae obtained from different sources induced different levels of disease on mango. The Department of Science and Technology (DoST) said it launched a three-year project to find mango strains resistant to scab and stem-end rot diseases. SER is considered to be the second most severe disease in mango fruit, the ï¬rst being anthracnose caused by Colletotrichum gloeo- Major post harvest diseases in the world are: Anthracnose Stem end rot Soft rot : Alternaria rot, Aspergillus rot â¦ Losses associated with stem end rot (SER) of avocado fruits have been reported in all avocado growing regions of the world. On samples from trees with a record of low stem end rot levels, colonisation did not extend into the most recently produced flush of stem tissue. The DoSTâs Philippine Council for Agriculture, Aquatic, and Natural Resources Research and Development (PCAARRD) announced a search for mango varieties and strains resistant to such diseases. Table 1. In Kenya, mature avocado fruits present SER symptoms during storage and marketing, but the disease causal agent(s) has not been established. This study aimed to identify the fungal pathogen(s) associated with avocado SER in Kenya and evaluate its pathogenicity. This report is the first of stem-end rot of mango caused by L. theobromae in Japan, and we propose the name "jikugusare-byo" in Japanese. It can be important, es-pecially when anthracnose, the most important post-harvest problem on fruit, is well con-trolled. Control measure of stem end rot disease, hot benomyl (52 deg C) 1000 ppm for 5 mins, dip and followed by prochloraz at 250 ppm for 30 sec were tested with mango infected with all stem end rot pathogens. Aspergillus rot is The mango fruit is susceptible tomany postharvest diseases caused by anthracnose (C. gloeosporioides) and stem end rot (L. theobromae) during storage under ambient conditions or even at low temperature. Abstract Mango malformation (MMD) is an economically significant disease of mango growing regions and a notifiable disease in Australia. M~or diseases of mango (those marked with an asterisk have been reported in Hawaii).Disease Fruit Diseases Anthracnose* Stem-end decay Bacterial black spot Rhizopus soft rot Soft brown rot Jelly seed* among others, stem-end rot (SER) pathogens (Prusky et al.

Sangchote, S. (1991). Bagging had no significant effect on disease incidence. The symptoms of Stem-end rot and anthracnose are the two major postharvest diseases of mango, which reduce the fruit quality, shelf life and marketability (Krishnapillai and Wijeratnam, 2013). gloeosporioides Penz., and stem-end rot, quarantine control of the mango seed After treatment, all fruit (wrapped and caused by Diplodia natalensis P. Evans weevil (Sternochetus mangiferae Fab.). Stem end rot is a well-established postharvest disease of mango caused by the fungi Neofusicoccum parvum (Pennycook & Samuels) Crous, Slippers and A.J.L. Stem-end rot is usually a post-harvest disease of mango fruit. 1. The fungus grows from the pedicel into a circular black lesion around the pedicel. Dothiorella dominicana has been the predominant cause of stem end rot at all sites. Diplodia Stem-end Rot of Mango Causal Organism: Lasiodiplodia theobromae Symptoms: The fungus enters through mechanically injured areas on the stem or skin. Stem end rot Botryosphaeria rhodina Dothiorella dominicana = Fusicoccum aesculi Botryosphaeria dothidea [teleomorph] Hendersonula toruloidea Lasiodiplodia theobromae = Botryodiplodia theobromae In general, the stem-ends of affected fruit appear Avocado fruit and stem-end rots are usually not obvious while fruit is on the tree. Stem End Rot A disease of importance in harvested fruit. Then Kensington Pride from twelve locations in Queensland and one in the Northern Territory have been monitored for stem end rot development. Post-harvest management The chemical fludioxonil is currently permitted for the management of stem end rot in mangoes.
