Another tree decline of unknown aetiology was also observed in north Queensland. A minor disease observed is leaf spot caused by the alga, Cephaleuros virescens. Harvesting and postharvest handling Most growers picked ripe fruits when they dropped from the tree. To reduce fruit damage caused by the fall, tarpaulins or nets can be erected below the tree during the ripening months. Selective harvest before the fruit is ripe, as is practised in Thailand, will extend the shelf life, but this needs a great deal of skill and experience.
Thai growers use a combination of harvesting indices in selective harvesting.
