“…causes anthracnose disease on mangoes {Mangifera indica L.) and various other fruits worldwide (Barkai-Golan 2001). In mangoes, it is a major postharvest disease (Dinh et al 2003), especially in the susceptible cultivar 'Nam Dok Mai' (Sangchote 1987) and it is a significant problem for Thai exports, which are well received in overseas markets. Fruit infection commonly occurs in the orchard and results in serious decay problems in transit, at the market and after sale.…”

The effects of chitosan on mycelial growth and spore germination of Colletotrichum gloeosporioides were investigated on potato dextrose agar (PDA) containing 0%, 0.5%, 1.0%, 1.5%, and 2.0% (w/v) chitosan dissolved in 0.5% acetic acid. Complete inhibition of mycelial growth and spore germination was observed in the medium containing only 0.5% acetic acid. Media containing chitosan were less inhibitory, but the highest concentrations of chitosan, at 1.5% and 2.0%, were more inhibitory than the lower concentrations (0.5% and 1.0%). Chitosan treatment (0.5%, 1.0%, 1.5%, and 2.0%) of mangoes {Mangifera indica) previously inoculated with C. gloeosporioides resulted in a lower rate of disease progression compared with the controls. Chitosan concentrations of 0.5% and 1.0% had stimulatory effects on chitinase and P-l,3-glucanase activities. Additionally, chitosan coatings in mangoes delayed ripening and reduced respiration rate, ethylene production, and the loss of weight, ascorbic acid, and total titratable acidity. However, the firmness of mangoes treated at concentrations above 1 % caused a perceptible decline in sensory quality.

Botrytis cinerea infects waxflower (Chamelaucium spp.) flowers and can induce them to abscise from their petioles before disease becomes evident. Botrytis cinerea infection of flowers was studied on two waxflower cultivars by light and electron microscopy. Pot-grown waxflower flowers were harvested, inoculated with aqueous suspensions of B. cinerea conidia, incubated at 20-22°C and >95% RH and examined within 96 h post-inoculation (hpi). Conidial germination on petals started 4 hpi, penetration via germ tube tips was 6 hpi and protoappressoria were formed 8 hpi. Germination on petals approximately doubled every 4-6 h to 18 hpi. Conidial germination was ca. 50% at 22-24 hpi. Botrytis cinerea infected most waxflower flower organs, including petals, anthers and filaments, stigma and hypanthium, within 24 hpi. Hyaline and lobate appressoria were observed 36 hpi. Infection cushions on stamen bases were formed 36 hpi by saprophytic hyphae that originated from anthers. This infection process can give rise to tan-coloured symptoms typical of botrytis disease that radiate from this part of the flower. Subcuticular hyphae were present at high density near stamen bases and evidently resulted from multiple penetrations from single infection cushions. The subcuticular hyphae grew within the hypanthium and towards the centre of the floral tube. When flower abscission occurred, floral tube tissues close to the abscission zone remained uninfected. This observation infers possible transmission of a signal (e.g. ethylene) upon B. cinerea infection. Thus, B. cinerea causes flower abscission apparently as a defence response.

“…'Keitt' and 'Kensington Pride', were classed as resistant, whereas 'R2E2', 'Nam Doc Mai', 'Kent', 'Calypso', and 'Honey Gold' were classed as susceptible (Donald, 2006). Many mango cultivars like 'Alphonso', ' Baramasi', 'Carabao', 'Carrie Early Gold', 'Keaw', 'Kent', 'Kishen Bhog', 'Rad', 'Saigon', 'Tommy Atkins', and 'Van Dyke' have been found to be more tolerant to anthracnose (Peterson, 1986;Dinh et al, 2003). Cultivar differences in susceptibility have been reported in India and other locations with maximum damage observed on 'Neelum' in Kerala and Tamil Nadu (Prabakar et al, 2005), whereas cultivars 'Edward', 'Mayaguazano', and 'Elamandi' were resistant to anthracnose (Sohi et al, 1973).…”
