Cocoa sunscald & cherelle wilt (137)
Pacific Pests, Pathogens and Weeds
Pacific Pests, Pathogens and Weeds

Summary

  • Worldwide distribution. Natural processes occurring on cocoa, not diseases.
  • Sunscald – Either cocoa is grown without shade, or shade is removed and soil nutrients not sufficient to support healthy growth. Top leaves yellow, fall, and young stems dieback. Lower shoots develop.
  • Cherelle wilt – Young pods, 6-8 cm, first red or green, stop growing, lose colour and decay, turning black, but remaining attached. Although a natural process, it can be increased by Phytophthora black pod rot.
  • Cultural control: important factors are: spacing; a light shade preferably from a tree in the legume family, moist soils (not too wet or dry); mulch; control of black pod.
  • Chemical control: none recommended.
