| Abstract | ||||
| The effectiveness of some mineral salts, as wood preservative, againstPalm powder post beetle, Enneadesmus trispinosus Oliv., were studied under laboratory conditions. The obtained results detected that sodium fluoride and copper sulfate are good materials for protection palm fronds from the infestation by bostrychid beetle, E. trispinosus . Dipping technique of palm fronds cutting revealed high toxic effect and complete protection against palm frond beetle, E. trispinosus, at the concentration 8% (8 x 104 ppm) of sodium fluoride gave 100% protection, while copper sulfate appeared 100 % reduction at concentration 12% (12 x 104 ppm).The lost wood weight resulting from infested cuttings with this borer was decreased with increasing the salt concentration, the percentages of loss wood of palm fronds was 9.05 % at concentration of 0.8% of sodium fluoride, and was 29.49% at the concentration of 0.25%sodium fluoride. As well as, t he percentage of lost wood weight was 9.17% at the concentration of 12% of copper sulfate, and 30.34% at the concentration of 0.25% of copper sulfate. | ||||
