The best time to manage weeds post-harvest

The best time to manage weeds post-harvest

Reading Time: < 1 minute Fall is a good time to spray perennials and winter annual weed species because pre-winter management can help preserve critical soil moisture for the following spring. Controlling winter annuals when they are small also offers better control. That said, spraying immediately after harvest will not offer the best results. Perennials that are chopped to stubble […] Read more


The bud stage, when Canada thistle is most palatable to livestock, occurs when purple flowers start opening.

The time to attack Canada thistle is now (or soon)

A herbicide application after a hard frost can hit the noxious weed where it lives

Reading Time: 3 minutes Of all the weeds beef producers should focus on, Canada thistle is high on the list. Livestock avoid the prickly plant and it’s said to cost Canadian ag and forestry $7.5 billion in lost revenue annually. Fall control on pasture might be one of the most effective tools in stopping growth of the noxious weed, […] Read more

Pre-harvest is the time to protect the crop’s marketability for international markets

Reading Time: 4 minutes Maximum residue limits can affect the marketability of a crop, so farmers need to heed them, say crop market experts. “Because we produce so much beyond what we need for our domestic demand for food, we really do need to keep in mind market access and those requirements that we see with our export partners,” […] Read more

At Ag in Motion: Herbicide resistance fight needs integrated seed management

'Those seedlings we don’t manage to kill (are) probably the most herbicide-resistant'

Harvest weed-seed control takes aim at reducing herbicide-resistant weeds that western Canadian farmers find more and more every year. At the Ag in Motion outdoor farm show this week, field residue management manufacturer Redekop won the Innovations Award for Environmental Sustainability for its harvest Seed Control Unit, which destroys more than 95 per cent of […] Read more

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
