Subject: buckthorn is visible
Importance: High

NOW IS THE TIME TO FIND BUCKTHORN, the overwintering host for soybean
aphid.

This year, I've finally remembered to send an email. Most trees and 
shrubs have changed color and leaves are dropping.  Buckthorn is 
still dark green and covered with leaves - very obvious even at 70 
mph.  So if you are interested in mapping buckthorn in your area, now 
is the time.

For tips on ID, check out the bulletin that Steve Gower and I wrote in
2002
E2803, Buckthorn in the Landscape: Identification and Control
