Symptoms
- Anthracnose: Botryodiplodia palmarum
- This disease occurs in the nursery.
- It is recognized by regular or irregular brown to black leaf blotches surrounded by yellow haloes, which develop along the margin, centre or tip of the leaves.
- It causes heavy seedling loss.
Management
- The disease can be controlled by spraying Mancozeb or Captan at the rate of 200 g/100 litres of water.
- Copper fungicides should not be used because of the extreme susceptibility of oil palm seedlings to copper burn (scorching).
