Anthracnose. On breadfruit in Pacific usually found on leaves associated with leaf necrosis or large grey irregular leaf blotches, which are restricted by the main leaf veins, presumably following damage by wind or drought; also associated with a fruit rot. On mango found on leaves and commonly on fruit, which may become covered in black spots. On yams associated with black spots on leaves and stems, sometimes leading to rapid plant death and then sometimes given the name of ‘lightning strike’.
