Control of stem end rot (Dothiorella dominicana) and other postharvest diseases of mangoes ( cv. Kensington Pride) during short- and long-term storage.

Immersion in hot water (52 deg C for 5 min) plus benomyl (Benlate 50 WP 1 g/litre) provided good control of stem end rot on mangoes following inoculation with either D. dominicana or Lasiodiplodia [Botryodiplodia] theobromae during storage for 14 d at 25-30 deg . In the same storage conditions prochloraz (as Sportak 45EC), DPXH6573 (40EC), RH3866, (25EC) and calcium chloride did not control stem end rot (D. dominicana). During long-term storage in a controlled atmosphere (5% O2, 2% CO2, 13 deg for 26 d followed by air for 11 d at 20 deg ) hot benomyl (as above) followed by prochloraz (45 EC, 0.55 ml/litre, 25 deg , 30 s) provided effective control of stem end rot and anthracnose. The addition of guar gum to hot benomyl improved control of stem end rot in the combination treatment. Hot benomyl alone was ineffective. Other diseases, notably Alternaria rot (A. alternata) and dendritic spot (D. dominicana) emerged as problems during controlled atmosphere storage. A. alternata and dendritic spot were also controlled by hot benomyl followed by prochloraz. Penicillium expansum, Botrytis cinerea, Stemphylium vesicarium and Mucor circinelloides are reported as postharvest pathogens of mango, cv. Kensington Pride, for the first time.
