Mango angular leaf spot (325)
Pacific Pests, Pathogens and Weeds
Pacific Pests, Pathogens and Weeds

Summary

  • Worldwide distribution (probably). On mango. Lack of information on importance; often with the more serious anthracnose (see Fact Sheet no.09).
  • Spots may merge in wet weather forming large black areas causing leaf fall.
  • Leaf spots, angular to circular, up to 6 mm diameter, with small dark centres and wide greenish halos. Dark underside where spores form.
  • Spread in wind and rain.
  • Cultural control: Similar to anthracnose: prune canopy allowing air movement so that leaves dry quickly, and keep height <4 m; if practical, remove dead shoots, and collect fallen leaves, and burn.
  • Chemical control: if required, use products as for anthracnose, e.g., copper or mancozeb, beginning when flowers first appear, continuing until the pre-harvest waiting period.
