Manage Weeds On Your Farm - SARE

“I am most pleased to share the good news that our long-awaited SARE-sponsored book “Manage Weeds on Your Farm – A Guide to Ecological Strategies” by the late Chuck Mohler, John Teasdale, and me has now been published online and is freely available for download from the SARE website link below. This is a great resource that took Chuck and I (and many student assistants) numerous years to complete. The coming onboard of John Teasdale as a co-author during the last two years was enormously helpful especially given Chuck's failing eyesight and his untimely passing.”--Toni DiTommaso, Professor and Chair, School of Integrative Plant Science Soil and Crop Sciences Section, Cornell University
