What is the treatment for the white pine weevil, now that Methoxychlor has been taken off of the market?



Answers:
"At present, dimethoate is the only product
registered to control the white pine weevil. It
is registered for use on Sitka spruce trees.
Dimethoate is a systemic insecticide. It should
be applied as a liquid, to the leader stem, to
the point of runoff. Spray at the time of egg
laying, generally early May.
It is advisable to spray a single branch or dip
several needles in the spray solution and wait
for three to four days to check trees for
sensitivity to the product."
