Glyphosate Trends in Agriculture

The herbicide glyphosate has been in use for over 40 years.  It is non-selective (kills all plants), it is inexpensive and has extremely low toxicity.  These attributes made it an important tool for municipalities, farmers, and homeowners. Use increased starting in 1996 with the advent of glyphosate-tolerant (marketed under the brand name “Roundup Ready”) crops, which have expanded in acreage ever since. Rob Saik (@rsaik) is an agronomist with significant experience and accolades in Canadian agriculture.  Along with his collaborator Chris Dufault, they compiled and analyzed Ontario government data on glyphosate use, and reported these trends. Rob describes the report and its findings.
