[CANUFNET] Cottony Ash Psyllid

[Sarah Regent via CANUFNET]

Hello Everyone

I have discovered a cottony ash psyllid problem on the Manchurian ash in downtown Moose Jaw. All of the trees are about 20-30 cm diameter at breast height and in tree wells. The leaves aren't showing much distortion, maybe 5% of leaves are distorted on the worst tree. From what I can tell it's mostly second generation psyllids creating a lot of cotton, so I have hope we can get the psyllid population under control before they do serious damage.
What are other municipalities doing to control cottony ash psyllid? What are your thoughts on the efficacy of the treatments you've tried?

Thank you in advance.
