Study the effect of mechanical injection technique on controlling red palm weevil

الملخص EN

Field experiments were carried out to develop and evaluate a hydraulic injection device at El-Kasassen Horticultural Research Station, Ismailia Governorate, Egypt, and El-Salehia farms, Sharkia Governorate, Egypt.

A hydraulic injection device has been developed to be suitable for controlling Red Palm Weevil (RPW) at young date palm also to determine and control the injection dose in young date palms and offshoots especially at top infestation.

The performance was conducted under the following parameters: four injection pressures ١٠٠, ١٥٠, ٢٠٠, and ٢٥٠ kPa., three different diameters < ٣٠, ٣٠-٤٠, and ٤٠-٥٠ cm, three different materials for controlling, two insecticides (chlorpyrifos and profenofos (٤٨%) and natural material (Neem extract) on three different palm tree varieties, i.e., Hayani, Samani and Zaghlool.

The performance of the developed hydraulic injection device was evaluated taking into consideration: controlling spent time and productivity, controlling efficiency, total consumed power, and controlling cost.

From the obtained data it was concluded that, the proper values for red palm controlling at Hayani variety were obtained under injection pressure of ١٥٠ kPa, palm tree diameter of ٣٠-٤٠ cm and chlorpyrifos insecticide.
