Waterhemp on the rise

Manitoba’s list of affected municipalities keeps growing

By
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

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

By
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,”

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'

By
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

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

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

By
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
“When you’re looking at the sprayer, how it’s physically put together in terms of the structure and how it’s operated, we want to understand how that impacts the potential for spray drift.” – Lorne Grieger , PAMI.

Air disturbance from the sprayer itself may be affecting your drift risk

We’ve come a long way with sprayers. We’ve made them bigger, we’ve made them faster and with new visual technology and artificial intelligence, we’ve even made them smarter. Now, research by the Prairie Agricultural Machinery Institute (PAMI) along with the College of Agriculture at the University of Saskatchewan and Agrimetrix in Saskatoon is asking, ‘Can

Keeping your herbicides on target

Herbicide resistance, seed technologies add complexity to spray decisions

By
Glacier FarmMedia – Off-target movement of herbicides carries a risk to your crops, the neighbour’s crop and insurance premiums. With the arrival of Group 4 and Group 9 herbicide technologies, growers may think weed management is simpler. But resistant weed biotypes confound that notion and challenge growers and their advisors with tank-mix solutions and application

French court bans sale of two Touchdown glyphosates

Court cites lack of analysis of effects on wildlife

By ,
Paris | Reuters — A French court has banned the sale of two glyphosate-based herbicides produced by Swiss chemical group Syngenta because of a lack of analysis on the chemical’s potential harm to some wildlife. “The decision on Sept. 30, 2020 by French health security agency ANSES to renew the marketing authorization for the chemical

Is the water in your sprayer neutering your herbicide?

Calcium, magnesium, sodium, iron and potassium cations in sprayer water will bond with herbicide molecules, such as glyphosate, making them ineffective

What’s on your spring burnoff checklist?

Set yourself, and your crop, up for success from the get-go

By
It’s been a long, cool spring and farmers have had extra time for field preparations. Sprayers and seeders are poised and ready for action and, when the temperature hits growing degrees, everything will happen fast. The first happening should be the spring burn-off. “I’m a big fan of burn-off spraying,” said Manitoba Agriculture weed specialist
