Summary
The incidence of stem splitting and breaking is widespread in areca. This is not caused by the use of Bordeaux mixture for the control of fruit rot as was presumed by some growers. Exposure to the hot afternoon sun and the consequent scorching of the tender portions is the prime cause. Further damage is caused by the invasion of the affected tissues by more than one species of wound parasitic fungi. Provision of adequate shade is the best method of preventing this. The damaged portion is invariably between the western and southern sides of the stem. Any neglect in providing for shade at the planting time cannot be rectified easily later.
