Abstract
Field experiments were carried out to evaluate the efficiency of five manual trunk injection methods for controlling red palm weevil, Rhynchophorus ferrugienus (Olivier). Fifteen date palms with different status of infestation (5 limited, 5 moderated and 5 severe) for each method was injected by Chloropyrifos 48% EC at rate of 0.3%.
One of the most effective manual injection methods was compared with a mechanical device using Phenothoate 50% EC solution at the rate of 0.3%. Data showed that, the manual method was more successful than mechanical device. The manual method caused 100% recovery in the lowest level of infestation only, while it caused 80% recovery at the other two levels of infestation.
