I say this because even if you get rid of all the cedar on your property, they're still going to be around on neighboring properties. And if yours had cedar apple rust, those likely do too.
Eliminate completely? No, not if it's endemic to the area.
However, the resources I pulled up re this
thread indicated that the high risk of infection happened in a fairly small zone. It dropped off substantially with distance. (I'll try to find the resource and post a link.)
Still, I agree, it's a game of whack-a-mole. Or cat and
mouse. You have to be on top of it. And the close cedars that are infected have to go.
How much work would be involved in creating a "no cedar" buffer zone?
EDIT:
It seems there is a range of opinion regarding the distance the rust spores will travel in high concentrations. The more optimistic sources say a few hundred yards against the prevailing wind and at least 1 mile upwind. So local control may or may not be effective. Personally, that woudn't stop me from trying though.
