<b>Anthracnose</b> <i>Colletotrichum gloeosporioides</i>
The disease attacks young plant tissues and can cause severe crop loss when it infects flowers, which turn black and die. Young leaves, cashew apples and nuts are similarly affected. Infected young terminal shoots die back. The disease is promoted by warm, damp conditions.
- Prune dead branches and twigs and remove from the field. They constitute the principal source of infection.
- Though pesticide application on cashews is not practiced in East Africa, copper based fungicides are known to be effective against anthracnose.
