Greasy Spot, a Serious Endemic Problem for Citrus Production in the Caribbean Basin

摘要: siderable defoliation and is responsible for reduced yields fruit size, but those losses have been quantified in only one case. Whiteside (55) found that fungicide applications increased the yield of Pineapple oranges (Citrus sinensis) by 25%. In addition to incurred as a result greasy spot–induced defoliation, M. citri known cause rind blemish on citrus (46,49). Fruit infection produces symptom originally referred pink pitting. This disease was thought be caused Cercospora sp. (31). (47,49) demonstrated infected through stomata killed guard cells few surrounding stomata, producing tiny lesion. However, when high numbers infections occurred, significant developed which he termed spot blotch. Greasy blotch significantly reduces external quality fresh market. It serious problem grapefruit (C. paradisi), can also occur other citrus. Rind percentage acceptable market 5 10% annually.
