Abstract

Kiln dried coconut lumber with 16 percent average moisture content were subjected to five common wood working processes composed of planing, boring, shaping, turning and sanding. Tungsten carbide cutters were used in each process except in sanding where silicon no. 60 sandpaper was employed. The coconut lumber measuring 25 mm thick by 125 mm wide by 1.25 m long have density range of 200 to 900 kg. per cubic meter.

Abstract

Marine exposure tests of sawn coconut lumber were carried out for three years to determine the resistance, of treated coconut timber to marine borers. The test panels measuzing 50 mm x 100 mm x 450 mm, were installed in sea water between October, 1981 and September, 1984. Results showed three promising treatments. These were the vacuum/pressure method using chromated copper arsenate, the modifted double diffusion treatment employing mixture of copper adphate, sodium dichromate and arsenic pentoxide, and the hot and cold bath treatment with coal tar creosote. The specimens treated by these preservative systems showed trace or slight sur­face infestation while the untreated wood panels indicated from deep and extensive infestation to failure due to attack of marine borers. The perfomance of the treated medium density specimens appeared to be inferior than the hard samples indicating that only the latter materials should be used for marine structures.

Abstract

The root absorption technique has been shown to be very ef­fective method for the control of coconut leef feeding caterpillars. However, this method, in order to be effective, requires a good system for monitoring the population level of the pest and a well organized and coordinated pest control teams. Like the trunk injection method the root absorption tech­nique has also many advantages: high effectiveness, good distribu­tion of insecticides in the leaves, efficient, less harmful, long remanence does not affect the natural enen‑des, thus a good method to use for integrated pest control. Furthermore, unlike the trunk injection method, the root absorption technique utilizes the root, not the trunk, of the coconut palm for introducing the pesticide. Hence, not injurious to the tree as well.
