This is time of year I spray my chestnuts to protect them from the
chestnut weevil. Carbaryl is the only recommended pesticide for this
weevil. Now I find that Sevin has been reformulated and does not
contain carbaryl. I read the label and the new stuff is not recommended
for the chestnut weevil.
I find this to be a bait and switch type situation and it irritates me.
