“…Lasiodiplodia theobromae was isolated at high rates from flowers, peduncles, fruit-bearing shoots, and fruiting mother shoots in Japan (Takushi et al, 2019) In the third week after flowering, the incidence of D. dominicana and D. mangiferae with the fruit-pedicel connection tissue of mango declined in coincidence with early fruit-fall, suggesting that early infections by Dothiorella spp. may cause fruitlet abortion (Johnson et al, 1991b). After remaining low levels for the next six weeks, the incidence of Dothiorella spp.…”

“…The earliest indicator of stem-end rot incidence at harvest was the infection level in peduncle tissue sampled 11 weeks after flowering (Johnson et al, 1991b). As the fruit ripens, some pathogenic fungi switch from endophytic colonization to necrotrophic stage and cause stem-end rot (Galsurker et al, 2020).…”

“…-Ayr (1989). At a site near Ayr, north Queensland, inflorescences and fruit were collected at random from five tagged trees used in previous surveys (Johnson et al, 1991) and consigned to Indooroopilly. Because of the delay (72 h) in the collecting of samples in Ayr and processing in Indooroopilly, it was expected that changes in the microflora of florets and fruit could occur in transit.…”

During flowering and fruit set of mango (Mangifera indica L.), colonisation by fungi (Alternaria alternata, Cladosporium cladosporioides, Dothiorella dominicana, Dothiorella mangiferae, Dothiorella sp., Epicoccum purpurascens and Pestalotiopsis sp.) increased as the flowers senesced and young fruit formed.In the third week after flowering, the incidence of Dothiorella dominicana and Dothiorella mangiferae associated with mango fruit-pedicel connection tissue declined coincidentally with early fruit-fall, suggesting that early infections by Dothiorella spp. may cause fruitlet abortion. Dothiorella spp. levels in fruit-pedicel connection tissue remained low for the subsequent 6 weeks, after which they increased. By 16 weeks after flowering, the incidence of Dothiorella spp., determined by isolation from fruit-pedicel connection tissue, was similar to the incidence of stem end rot caused by Dothiorella spp., which developed in fruit harvested at that time. By contrast, the frequency of detection of Dothiorella spp. in peduncle tissue peaked 11 weeks after flowering, when the levels of stem end rot developing in fruit were already similar to the levels recorded in fruit harvested at 16 weeks and later.The results suggest that in fruit and fruit-pedicel tissue, colonisation might arise from Dothiorella spp. occurring endophytically in the peduncle. The earliest indicator of stem end rot incidence at harvest was the infection level in peduncle tissue sampled 11 weeks after flowering. Early assays of peduncle tissue for Dothiorella spp. might prove useful for selecting crops with low stem end rot infection levels.

“…and stem end rot caused by Botryodiplodia theobromae Pat. were responsible for 26.7% decay (Jeffries et al 1990;Johnson et al 1991;Sharma et al 1994). Chemical fungicides provide the primary means for controlling post harvest fungal deterioration of fruits and vegetables.…”

The essential oil extracted from the leaves of Amomum subulatum Roxb. (Zingiberaceae) has been evaluated for efficacy in the control of mango fruit rotting due to fungal infections. The essential oil of A. subulatum exhibited absolute antifungal activity against two mango rotting fungi viz. Botryodiplodia theobromae Pat. and Colletotrichum gloeosporioides Penz, the common storage fungi causing stem end rot and anthracnose disease of mango fruits. The oil showed its absolute fungitoxicity at the minimum inhibitory concentration of 500 µL/L. Its fungitoxic potency did not alter even on a high inoculum density of the test fungi. The Amomum oil significantly enhanced the shelf life of mango fruits by controlling anthracnose disease as well as stem end rot for an additional five and six days, respectively. The oil also inhibited pectinase and cellulase enzymes secreted by the test fungi during pathogenesis and exhibited a wide range of fungitoxicity against 13 fungal isolates. Gas chromatography‐mass spectrometry analysis of the oil found 1, 8 cineole to be a major component. The LD50 of Amomum oil was found to be 22,070 mg/kg of body weight in mice (Mus musculus L.) when administered for acute oral toxicity. Keeping in view the side effects of synthetic fungicides, A. subulatum oil may be recommended as a botanical fungitoxicant of plant origin to control the rotting of mango fruits and to enhance their shelf life because of its nonmammalian toxicity and in vivo efficacy.
