Due to the adverse weather conditions and loss of fruit in many areas, there 
will be the initial response of thinking one does not need to be too 
concerned about pest control.  Actually, one will need to be a bit more 
diligent in monitoring, especially for fungal and bacterial diseases.  After 
any kind of weather related injury, fungicides still need to be considered. 
Damage breeds disease.  In fact, a good copper spray just prior to a light 
frost will add protection against that frost.

In the case of plum curculio, there is a great deal of information available 
at http://web1.msue.msu.edu/vanburen/plumcurc.htm.  I am also in the process 
of developing an early detection trap that will capture adults as they are 
flying into the orchard, rather than the previous trunk or triangle traps 
that generally do not work.  I will be starting my trials this spring with 
the use of a plum curculio lure and plum essence combination in a Trece 
Delta Pherocon VI trap.  I will continue to post results as they become
