Glyphosate Management – Part 1 of 3

Last week Matt Gosling went to Monsanto Canada headquarters in Winnipeg, The following 3 part series is a summation of glyphosate management in the prairies. 


Last week 13 agronomists, including myself, took in 2 days in Winnipeg with Monsanto to learn more about their company and their products.  I can’t remember ever knowing a day where Monsanto wasn’t put in some sort of ‘bad-guy’ spot-light from collecting TUA’s 14 years ago as a summer crop-scout, and even today with glyphosate resistance being common conversation in our Alberta backyards.  Historically, glyphosate has been one of the more significant tools producers have had for weed control and harvest management.  Easy to use, cheaper over time, and it worked.  Heck, even cowboys started growing canola up here & no offense, I was one of them!

With the ease of growing Round-Up Ready crops fueled by hot commodity prices and cheap glyphosate, resistance has shown up in kochia the last 2 years in Alberta.  The good news is, that of the almost 30 sites in Alberta and SW Saskatchewan, most, if not all were all on chem-fallow.  As Ieuan Evans told me once, “80-90% of weed control is based on competitive crops”.  Fallow acres in the province are shrinking with these grain prices and moisture conditions, so this is a good step.  Some quick facts about weed resistance – 98-99% of the Wild Oats are controlled by Group 1&2 products… 96% on pulses; 17 genus and 24 species world wide are glyphosate resistance; there’s 58 weeds resistant to herbicide in Canada as of 2012; 40-60% of Wild Oats are Group 1 resistant; and 85-95% of Kochia has some sort of Group 2 resistance. Part of those last facts I gathered from BASF during their grower meeting in Strathmore.


Stay posted for parts 2 and 3.
