 This will be our last regular Pest Alerts of the season thanks to grant funding provided by the Northeastern IPM Center for 2014 and 2015. Funding paid for field scouts in Rhode Island, Massachusetts and Vermont to scout vegetable farms in each state and publish findings to a regional farmer audienceeach week throughout the season. Special thanks goes to: Andy Radin and Lauren Breene at URI; Ann Hazelrigg, Mollie Klepack and Anya Rose at UVM; and Ruth Hazzard, Sue Scheufele and Lisa McKeag at UMass for diligent scouting and careful reporting.
