New dicamba- and glyphosate-tolerant soybeans offer more weed control options and are another tool to address herbicide-tolerant weeds, but farmers need to take steps to avoid dicamba drift and spray tank residue, Manitoba officials say. What’s been happening in Arkansas underscores the risk dicamba drift presents. The U.S. state of Arkansas on Friday announced a […] Read more

‘Wake-up call’ needed for resistance
Provincial crop expert says it’s time to stop pretending it’s not ‘a huge issue’
Reading Time: 3 minutes Weed resistance has been an issue in crop production for many years, but is coming to the forefront as increasing numbers of weeds are no longer responding to herbicides. “Most producers are aware of the issue, but unless it affects them directly, don’t see it as a huge issue,” said provincial crop specialist Harry Brook.

Know your enemy and its destructive potential, says provincial crop specialist
There’s a critical window for controlling weeds, but it depends on both the crop and the threat posed by individual species
Reading Time: 2 minutes All crops have a critical weed control period when they are most susceptible to significant yield loss from weed competition. The critical weed control period for canola is around 17 to 38 days after emergence. Peas can be as early as two weeks after emergence. “Other, more competitive crops, like the cereals, have a less […] Read more
EU to propose 10-year licence renewal for glyphosate

Herbicide resistance is everywhere you look
This year it’s Alberta’s turn to be surveyed by Ag Canada — but researchers already know the news won’t be good
Reading Time: 3 minutes If you’ve found herbicide-tolerant weeds in your field, you’re not in the minority. Weed resistance is increasing worldwide, so it’s really important that Prairie growers understand growing herbicide tolerance, says one of the country’s top resistance experts. “Group 2 really overshadows all the other groups in terms of weed resistance,” said Hugh Beckie, a research […] Read more
