Black irregular-shaped spots on mango fruit, with cracks (right), caused by bacterial black spot, Xanthomonas axonopus pv. mangiferaeindicae The main symptoms of bacterial black spot of mango appear on leaves and fruits but twigs and branches may also be affected in severe cases. Initially, small black and water-soaked lesions occur on the leaves. These spots are surrounded by chlorotic margins and limited by the veins Bacterial black spot was first recorded in the NT in 1981 in the Darwin area. Since then it has appeared in most areas in the Top End where mangoes are grown. The bacterium that causes black spot is called Xanthomonas campestris pv. mangiferae-indicae. It can attack leaves, twigs and fruit Many small black water-soaked spots on mango fruits and leaves can be caused by bacteria. This is the so-called bacterial black spot disease. Spots appear on the leaves, stems and fruits. On the leaves the spots are black and water-soaked

The scab fungus attack leaves, panicles, blossoms, twigs, bark of stems and mango fruits. Spots are circular, slightly angular, elongated, 2-4 mm in diameter, brown but during rainy season, lesions differ in size, shape and colour. Symptoms produced by the disease are very much like those of anthracnose Mango bacterial black spot is a very serious disease of mango. In infected orchards, chemical control is difficult and on some farms in Australia, for example, 90% of the fruit has had to be thrown away because the spots on the fruit make them unacceptable to the market This is the first report of a X. arboricola pathovar on mango in China inducing a disease for which we propose the name of bacterial leaf spot to distinguish it form the bacterial black spot caused by Xcm. Further studies are needed for determining pathovar sta- tus of the strain
