Christmas Tree IPM Update 3.9.16

Coming out of hibernation?  No, coming out of education season so I am actually in my office all week.  Winter aconite and snowdrops at my house and crocuses at Cornell!

Woo Hoo!  The new 2016 Cornell Pest Management Guide for Commercial Production and Maintenance of Trees and Shrubs (we don’t mind if you call it the Cornell guidelines for trees and shrubs) is out! Hard copies are available from the Cornell Bookstore in the next couple of days.   Have a photo that you think is cover-worthy?  Send it along and if it is chosen for next year, we’ll credit you (and I’ll send you a free copy of the 2017 guidelines!)

A (very small) shout-out for deer!  What?  Well, they don’t spread Lyme disease, although they do spread ticks.  Ticks can pick up the disease organism from mice, chipmunks, voles, etc. though, and they are out NOW.

Warm spring, early white pine weevil?  I expect so.  7-58 GDD (don’t know what that means?  Shoot me an email!) And one place to get your GDD is NEWA.

A couple of growers have told me that they are trying Tedders’ traps to monitor for white pine weevil.  I hope they keep me posted and I’ll keep you posted. Information on how to build your own – or buy them (there may be other sources, this one seems to pop up)

Enjoy the weather and have a great week!
