Efficacy: Oakville 2008-2010Heavily infested tree


20/23

Conclusions: TreeAzinNo direct mortality of feeding

adults;

Some gallery formation;

Highly active at inhibiting larvaldevelopment and preventing adult

emergence at very low dosages;

Reduced fertility and fecundity ofadults feeding on leaves.


21/23

CFS Conclusions: TreeAzin

Early summer injections at 12.5ml/in.

(5ml/cm) dbh at early stages of an

infestation should provide very effective

control of EAB.
