Snow 🙁 Sun 🙂 Just like life, we are getting some of each! Pretty philosophical for a Friday afternoon!
MSU has the NEW third edition of the USDA Christmas Tree Pest Manual for sale
I’ll let you know if I figure out why theirs is $5 and Amazon has it for $29.
The previous edition is a wonderful resource and I suspect this will be, too. I ordered mine today!
While you are there, check out their IPM Pocket Guide for Weed ID in Christmas Trees.
So – what do growing degree days mean for insect pest development in a year like this? I’ve got that question out to some entomologists. Do we use January 1 or March 1 as a baseline date? This year, both would tell you you could be spraying for white pine weevil now. Does that make sense with the temperature still bouncing around? I don’t think so. But you might want to be ready as soon as the weather smooths out a bit (it is spring and variation is what we expect after all). Do I know for sure? Nope! But I’ll let you know what I find out.
Questions, comments, information you need? Let me know!
