Pacific Pests, Pathogens and Weeds

Summary

  • Worldwide distribution. On mango. Many other crops are hosts of this fungus, including avocado, capsicum, coffee, eggplant, papaya, tomato and yam. There are different strains, infecting different crops and weeds. An important disease.
  • A wet-weather fungal disease, common on mango and yam. On mango, a blight of flowers, and young shoots, causing leaf spots, and post-harvest rots of ripening fruit.
  • Masses of spores are formed, and these are spread in wind-driven rain.
  • Cultural control: prune trees (<4 m tall) to allow air to move freely through the canopy, reducing the time that leaves and flowers are wet; resistant varieties.
  • Chemical control: use copper or mancozeb, beginning when flowers appear until the pre-harvest waiting period. For fruit: post-harvest dip in carbendazim or hot water (both for 5 minutes at 52°C).
