[NAFEX] Inexpensive Plum Curculio lure

Your comments are always worth a lot.  You used the tall Tedders traps,
along with a pheromone/plum scent lure?  Were the tree trunks painted white?
Did you use Surround?

I'm hoping that that combination will be fairly effective.  There are new
lures in development that may improve things.  

I was also impressed by a study that burned away the underbrush, cooking the
curculios - but there is the obvious danger, and no major trials.

Before our coop was able to go all organic, we permitted IPM foods where
that was the best option - timed pesticide exposures for the lowest use.  On
a realistic level, IPM can test cleaner for pesticides and herbicides than
organic, depending on degree of drift from other spray operations.  One
local grocery pays for produce testing and markets foods that have no
detectible residues.  Those are usually IPM.  

There's not much out here now that can't be grown organically.  I wonder if
IPM (limited use of Imidan, for example) is as respected back east as it
used to be here in the land of fruits and nuts?

This season we thought we would use the Great Lakes traps and lures on 
recommendation of our contracted entomologist.  Spent several hundred 
dollars and never caught a single PC but had plenty of fruit damage.  In the

past 15 years, Royal Oak Farm has never found a good trap and lure that 
works.  The good ole "shake the tree and see what falls" method has proved 
more valuable than any trap we have used.  We got more damage using the 
traps this year than ever before.  Next year, we go back to shakin'!

For what it's worth!!
