Summary

  • Worldwide distribution. In sub-tropics and tropics. On mango and cashew. An important disease.
  • Black, angular greasy spots bordered by veins often with yellow halos. Spots merge. Similar on fruits. Flower infections occur; stem cankers cause dieback.
  • Spread in wind and rain, insects and via the nursery trade.
  • Cultural control: disease free rootstocks and scions; nurseries far from orchards; windbreaks to protect orchards; harvest by cutting fruit stalks; prune after harvest and burn cuttings; tolerant varieties.
  • Chemical control: copper every 2-4 weeks, except during flowering, when mancozeb used instead.
