At Ag in Motion: Harvest weed control still in the mix

'You’re not going to spray your way out of this'

It’s a relatively new solution to the age-old problem of trying to get rid of weeds without broadcasting the seed or using increasingly less effective herbicides — mechanical separation and pulverization of weed seed. Harvest weed seed control might not be a golden bullet to tackle glyphosate-, fluroxypyr- and dicamba-resistant weeds, but according to Agriculture […] Read more
Timing of post-harvest spray applications is an important factor to consider. For example, some perennial weeds like Canada thistle require four to six weeks to regrow for a post-harvest herbicide application to be effective, which can be difficult in areas that receive early snowfalls.

Get out and get those boots on the […] Read more

Know why you apply: tips for assessing the need for pre-harvest aids

By
Canola can be a challenge to harvest if stands are too thin or too weedy or if there’s uneven ripening due to crop stage differences. Green stalks and weeds not only hinder harvest but can cause problems in storage too. In situations like these, many Prairie farmers opt to use pre-harvest aids as a late-season […] Read more

Franck Groeneweg and his family moved to Montana after 18 years of farming at Edgeley, Sask. It’s just over a year now since the family settled on their new 15,000-acre grain farm. This year, Groeneweg plans to apply a pre-seed burnoff, which may include glyphosate likely tank mixed with 2,4-D, or he may apply a Fortress-type product that includes dicamba and tribenuron, but it will all depend on the weed spectrum in the field.
