Our pressure here in Zone 5 is very heavy.
I usually leave 1 tree untreated with anything on our most wooded orchard edge
asa a control. Each season almost every apple has ovipositioning on
it. I set a trap in hte tree using a lure of plum essence and pheremones
to attract them to that tree and have trapped PC each season in it as
well. When I trap the first PC, usually prior to any ovipositioning since
the females are ready to lay eggs prior to fruit set, I know I have them
and will need to get some protection on the new fruit pronto. I do hold
out to coincide with my first CM spray.
A new video was jsut posted to the Growing
Produce web site on Optimizing
Insecticide Performance To Control Plum Curculio at http://www.growingproduce.com/gptv/?cid=2 . It is the best I have seen in describing the various
products for PC control.
