| Chemicals are applied to trees for many reasons such as insecticides repel or kill damaging insects. chemical is more effective when placed inside the tree. Tree injection are alternative methods of applying chemicals to trees that can be more efficient and targeted. The systemic insecticides imidacloprid and emamectin benzoate are available and labeled for soil drenching and/or soil or trunk injection. In a nursery of ornamental trees. Trees were treated through soil drench with imidacloprid 35% solution at rate of three ml concentrated insecticide/tree aged three years. After 2 months from the treatment, the canopy was recovered. New leaves were emerged from buds on the live parts of the tree. The outstanding Trunk injection technique was applied to control Red Palm Weevil, Rhynchophorus ferrugineus infesting ornamental palms in landscapes. Imidacloprid 35% was used at rate 2 ml concentrated insecticide/length meter of the palm. Recovery of palm canopy was observed after three months from injection and protection the palm extended three successive years. | ||
