FRISCO — Colorado forest experts are documenting an unprecedented outbreak of pine needle scale on conifer trees in Grand, Summit and Eagle counties that may be linked with the widespread application of pesticides used several years ago to try and kill mountain pine beetles.
The intensive use of those pesticides may have wiped out beneficial insects like predatory wasps and beetles that keep pine needle scale in check, said Granby-based Ron Cousineau, district forester for the Colorado State Forest Service.

GR: Similar unintended consequences of pesticide use are commonplace. With everything else we’ve learned about the dangers of pesticides, it appears that the people in federal regulatory are either dopes or stooges.
