The spots grow rapidly during wet weather, up to 200 mm, reaching the leaf tip. Finally, it should be noted that because of climate the pineapples from Uganda and Burundi are considered to be of higher quality in regard to flavor. This causes a soft, watery rot of the fruit flesh and makes the overlying skin glassy, water-soaked and brittle. In advanced cases, this leaves a fruit shell containing only a few black fibres. Wherever pineapples are grown. The spots grow rapidly during wet weather, up to 200 mm, reaching the leaf tip. associated with pineapple fruit rot and leaf spot mainly found on the fruits and leaves in Peninsular Malaysia. Pineapples that are cool-stored for prolonged periods can also develop other symptoms of chilling injury such as flaccid watery flesh, skin necrosis, crown wilting, and crown necrosis, but fruit with such injuries are often already damaged by internal chilling. Photo 2 Anna L Snowdon. The second issue is that farm-to-market transportation of pineapples is still carried out in rudimentary fashion in most cases and, together with the lack of a cold chain, this results in considerable losses of fruit and degradation of its average quality when it reaches markets. Biologically, pineapple has been studied for a number of health benefits and has been found effective in skin complications as an anticoagulant, in cardiovascular diseases as an analgesic enhancing the immune system, as a means of reducing gastric complications, as a uterine contractor in pregnancy, and as a tumor suppressor. Pineapple waste has been incorporated in up to 50% level in the feed of ruminants without any adverse effects (Makinde et al., 2011; Wadhwa and Bakshi, 2013).

Do not leave pieces of the fruit attached to the crowns when removing them from the plants; otherwise, this could lead to rapid infection at the base of the crown. Since the pineapple fruit develops from the fusion of fruitlets, those fruitlets near the stem end mature earlier than those at the stylar zone, leading to uneven ripening of the whole fruit. If harvested in wet weather, treat with fungicide. When the stylar zone pulp ripens, the stem zone pulp is overripe. It is a physiological disorder (i.e., not a pathogenic disease), known as chilling injury and caused by prolonged exposure to temperatures below 21 °C. It is the third most commercial important tropical fruit.

In pineapples, chilling injury is manifest most commonly by the fruit developing brown spots adjacent to the core; these are sometimes called endogenous brown spots. Pineapple has an anti-inflammatory effect, protects against colon cancer (Gani et al., 2015), macular degeneration, and arthritis. Figure 10.1. Temperatures of 15–18 °C induce the greatest injury but, as the fruits are usually shipped at 8 °C for 7–10 days from tropical production areas, they are usually consumed before any injury develops. Pineapple jam, which is perceived by the importer to possess a unique taste characteristic, comprises about half these exports, and guava and mixed fruit jam comprise the rest. Leaf rot in pineapples occurs when planting stock isn't kept dry.
