Early harvest opens options for fall weed control
Spraying tips to use once the combine is parked
[UPDATED: Oct. 11, 2023] An early harvest gives farmers the opportunity to get ahead of weeds for next season, says Manitoba Agriculture weed specialist Kim Brown. Weeds have had ample time to grow after harvest, making them prime targets for herbicide. Why it matters: As harvest winds down, attention turns to field preparation for 2024.
Waterhemp on the rise
Manitoba’s list of affected municipalities keeps growing
Manitoba’s ag sector is trying to hold the line against big yield-killing threats like waterhemp and Palmer amaranth. Unfortunately, the number of municipalities where waterhemp has been found just grew by two. “Waterhemp and Palmer amaranth are Tier 1 weeds regulated under the Noxious Weeds Act. They must be destroyed when they’re found,” said Manitoba Agriculture weed extension specialist Kim
Redekop pitches combine-mounted weed seed control
Manufacturer says combine-mounted unit will pulverize weed seeds
Farmer reaction to herbicide-resistant weeds may trend towards, “kill it with fire,” but the latest harvest tool out of Redekop Manufacturing has a different answer for weed seeds: pound them to oblivion. The Saskatoon-based manufacturer recently unveiled its seed control unit, compatible with John Deere combines. With resistant weed pressure and certain herbicides increasingly in
Transplanting herbicide-resistance advice from Down Under
Australia has something to teach Canadian farmers about herbicide resistance, at least, according to BASF’s latest online resource
On the other side of the world, farmers have learned some valuable insights about herbicide resistance that you can share. In Australia they’ve long been fighting this battle and the land Down Under has learned some tough lessons. The International Survey of Herbicide Resistant Weeds found Canada is third in the world in terms of
Monsanto aims to give farmers better information in weed resistance fight
The company is countering its competitors who tout their herbicides as tools in the fight to avoid herbicide-tolerant weeds
Monsanto Canada is fighting what it says is “fear-based rhetoric floating around about farming practices and (weed) resistance in Canada.” In a recent full-page advertisement in several farm newspapers, including the Manitoba Co-operator, Michiel De Jongh, Monsanto Canada’s president and general manager, said Monsanto should’ve addressed herbicide-resistant weeds sooner. “When you began to battle herbicide
Farm groups reject anti-GM crop report claims
The Canadian Biotechnology Action Network questions whether yield gains are due to GM technology
A report that claims genetically modified crops are no more productive than conventional ones doesn’t match the reality of what Canadian farmers find in their fields every year, farm groups say. The Canadian Biotechnology Action Network, which opposes GM crops, says in a report that yields of GM and conventional crop varieties “have increased at
Tank mixing weed killers helps delay herbicide-resistant weeds
But don’t forget to rotate crops, including fall seeded and perennials, advises AAFC’s Hugh Beckie
Tank mixing two herbicides with different modes of action targeting the same weed is a good way to delay the development of herbicide-resistent weeds, a study by weed scientists at the University of Illinois and United States Department of Agriculture concludes. “We don’t say that mixing is the end-all solution,” study co-author Pat Tranel of
Glyphosate resistance: Change now or pay later
A USDA-ERS report shows managing glyphosate resistance is more cost effective than ignoring resistance and farmers need to work together
The United States Department of Agriculture Economic Research Service recently published the results of a study into the economics of glyphosate-resistance management on U.S. corn and soybean farms. Through surveys and computer models it determined the relative costs of ignoring the problem versus taking action to address it. The following is an excerpt from that
