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.
