Levi, I doubt EAB is restricted to Boulder city limits and you are just down the road a bit from there. I have heard of wood infested material that was transported to Gunbarrel and probably beyond. My guess is EAB is in Longmont. Our Ash are moisture stressed and our late/early frosts have further stressed them. I think a real challenge will be getting good uptake. I took a tour of Boulder with Kathleen and saw a row of great looking healthy Ash trees, when I commented on it she told me they were part of Whitney's trial group. From my colleagues in the Midwest, everyone it telling me not to try to fight this from behind.
In the housing complex where EAB CO tree #1 was found they have treated other trees which were infested, they are alive but don't look great. The other issue is detection, these insects are very difficult to detect even for those that have extensive experience and thus confirmation of their presence lags about 3 - 5 years behind initial infestation. Down here in Denver Metro we are getting ready for the inevitable confirmation.
I was recently in Tucson and talking to people about treatments from all over the country and it's going to be interesting. Some companies did not have good luck treating with Imidacloprid and suffered huge losses when pressure increased. Tree-Age is the way to go and maybe as others here said down to 12 or 10 or less DBH. They might be able to treat a 50% tree in the Midwest but I doubt we can out here. With 4 native borers of Ash, low precipitation, and erratic climatic conditions we are at a distinct disadvantage. I think a solid nutrient program would also help uptake and wound closure but not too much high nitrogen.
Success will depend on timing, tree health, and proper treatment (type and application), in the Midwest there are still many healthy Ash and success rates high when properly managed.
