- Abstract
The article evaluates trunk injection of azadirachtin into elm trees using the Ecoject Microinjection System to cut the emergence numbers of red elm bark weevil. Weevil activity was monitored at weekly intervals in four weeks using sticky traps placed in the canopies. Results reveal a significant reduction of 55%-60% in weevil activity in early summer in the treated tree canopies versus the control. This indicates the method may be an effective management tool for this pest.
