Summary

  • Narrow distribution. Probably, a fungal disease of minor importance. Lack of research on control measures.
  • Spots roughly circular, up to 2 cm diameter, yellowish, grey or reddish brown with narrow red borders, and black fruiting bodies within. Centres of spots may fall out.
  • Spread occurs by rain splash or spores carried by wind.
  • Cultural control: plant at wider than normal spacing; collect and burn infected leaves; do not shade, i.e., grow beneath tall trees.
  • Chemical control: use copper, chlorothalonil or mancozeb.
