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. 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. 2013). 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. 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. Stem end rot severity continued to decline with increased duration of bagging, but there was no consistent effect on anthracnose severity after 56 days. 1C). Mango … Abstract Mango malformation (MMD) is an economically significant disease of mango growing regions and a notifiable disease in Australia. … マンゴー軸腐病および炭疽病の同時防除のための数種有効殺菌剤を用いた体系散布技術の確立 Systematic Application Technique using Several Effective Fungicides for Simultaneous Control of Stem-end Rot and Anthracnose Disease of Mango 2010).

Losses associated with stem end rot (SER) of avocado fruits have been reported in all avocado growing regions of the world. マンゴー軸腐病の防除手法の検討 (放電・プラズマ・パルスパワー研究会・放電・プラズマ・パルスパワー一般) Investigation of controlling stem-end rot of mango 電気学会研究会資料. 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* This study aimed to identify the fungal pathogen(s) associated with avocado SER in Kenya and evaluate its pathogenicity. Flesh CaFig. nonwrapped) were stored for 16-21 days 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. 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. Eleven species of Botryosphaeriaceae were associated with mango stem‐end rot in Malaysia. Major post harvest diseases in the world are: Anthracnose Stem end rot Soft rot : Alternaria rot, Aspergillus rot … SER is considered to be the second most severe disease in mango fruit, the first being anthracnose caused by Colletotrichum gloeo- 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. They were wrapped 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 Stem end rot Symptoms – A dark rot develops from the stem end as the fruit ripens after fruit harvest. Caused by Lasiodiplodia theobromae, affects mechanically-injured areas on the stem or skin. Mango post harvest diseases minimize fruit quality and cause losses. 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. 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). The symptoms of Stem canker Phoma sp. Stem-end rot is usually a post-harvest disease of mango fruit. The fungus grows from the pedicel into a circular black lesion around the pedicel. Aspergillus rot is among others, stem-end rot (SER) pathogens (Prusky et al. In Sri Lanka, Stem-end rot (SER) disease in 1. 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 DoST’s Philippine Council for Agriculture, Aquatic, and Natural Resources Research and Development (PCAARRD) announced a search for mango varieties and strains resistant to such diseases. A number of fungi including Ladiodiplodia theobromea, Coletritricum gloeosporiodes and Fotogercis mangiferea cause the stem end rot disease in mango. At a site with a history of high stem end rot … 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. 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]. In general, the stem-ends of affected fruit appear Stem end rot Botryosphaeria rhodina Dothiorella dominicana = Fusicoccum aesculi Botryosphaeria dothidea [teleomorph] Hendersonula toruloidea Lasiodiplodia theobromae = Botryodiplodia theobromae Kensington Pride from twelve locations in Queensland and one in the Northern Territory have been monitored for stem end rot development. Bagging had no significant effect on disease incidence. 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. The isolates reproduced the symptoms on mango fruits in an inoculation test and were reisolated from the inoculated fruits. 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. Title PATHOGENIC CHARACTERIZATION OF LASIODIPLODIA CAUSING STEM END ROT OF MANGO AND ITS CONTROL USING BOTANICALS Author … Endophytes cause mango stem end rot 227 1. Table 1. 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. It can be important, es-pecially when anthracnose, the most important post-harvest problem on fruit, is well con-trolled. In Kenya, mature avocado fruits present SER symptoms during storage and marketing, but the disease causal agent(s) has not been established.
