Troubling gaps within PMRA

An interview with crop protection expert Craig Hunter on the avalanche of change that may be heading toward Canadian farmers

By
Reading Time: 5 minutes Last year, calls rang out for growers and their organizations to voice their concerns about an ongoing review of hundreds of crop protection formulations. The lobbying effort carried added urgency over and above similar efforts from the previous two years. The Pest Management Regulatory Agency (PMRA) began conducting these reviews similar to those required in […] Read more
Rotary hoe and inter-row cultivation reduced weed biomass by 75 to 85 per cent in field pea and lentil, as seen in this photo of lentils after inter-row cultivation. When seeding rate was boosted, weed biomass in lentils was reduced an extra 16 per cent.

New methods of mechanical weed control show promise, but don’t expect a yield increase the first year

By
Reading Time: 8 minutes With the high and growing percentage of Prairie cropland infested with herbicide-resistant weeds, researchers are turning their attention back to mechanical control, but that doesn’t necessarily mean tillage. The Alberta Wheat Commission and Saskatchewan Pulse Growers are partnering on a three-year research project at the University of Saskatchewan which is evaluating in-crop weed clipping as […] Read more

By
Reading Time: < 1 minute Q: I’ve been battling hemp dogbane in my soybean fields. It produces a milky juice that can stain my beans. What can I do to knock back the top growth so it won’t affect crop quality? A: It’s good that your expectations are for top growth control of hemp dogbane (see figure 1), since it’s […] Read more

Agrimetrix takes aim at exploding sprayer myths

Farmers today need to spray several times a year, and two former AAFC researchers have formed a company to help them get the product to the right place at the right time

By
Reading Time: 7 minutes If Tom Wolf is the face of agricultural spraying in Western Canada, then Brian Caldwell is the hands. The two co-owners of Agrimetrix, an agricultural spray research and training company based in Saskatoon, share an overlapping skillset, but they have carved distinctive individual niches. Wolf spends much of his time talking about spraying in a […] Read more

Pest Patrol: Tackling prostrate knotweed on today’s farms

#PestPatrol with Mike Cowbrough, OMAFRA

By
Reading Time: 2 minutes Q: How do I get rid of prostrate knotweed in each of my major crops? A: In Ontario, prostrate knotweed is more frequently found in Huron County and on Brookston clay-loam soils under no-till or minimum-till production systems (Frick, 1990). It can thrive in compacted soils where other plants will struggle to grow well. Below […] Read more

The challenge of early weeds in soybeans

A two-pass weed control strategy makes a lot of economic sense

By
Reading Time: 5 minutes In an ideal world, it might not matter when a field of soybeans is sprayed, or whether it’s a soil-applied or post-emergence herbicide that’s used. But this isn’t an ideal world and application timing can be very important. So is the crop. In Country Guide’s spring Corn Guide, Dr. Peter Sikkema discussed the impacts of […] Read more

Pest Patrol: Dealing with willowherb

#PestPatrol with Mike Cowbrough, OMAFRA

By
Reading Time: 2 minutes Q: I’ve noticed small patches of a plant that was identified as “northern willowherb” in some of my fields. It seems tolerant to glyphosate. How do I control this before it becomes a bigger problem? A: This perennial weed has traditionally been found along roadsides and waste areas. In the last five years, more farmers […] Read more
In some parts of Eastern Canada, the problem weed can vary from ragweed to horsetail (pictured in soybeans).

The problem with problem weeds

Different regions, different crops and different species turn ‘control’ into ‘management’

By
Reading Time: 5 minutes It’s a message filled with contrasts. Weed management is simple yet complex. It’s all about improving your bottom line, but it adds a cost. And although it’s all about controlling all your weeds, it often gets judged on a single weed species. In spite of all the differences that come with farming in different regions, […] Read more

Pest Patrol: Dealing with cleavers

#PestPatrol with Mike Cowbrough, OMAFRA

By
Reading Time: 2 minutes Q: I had a field of winter wheat with cleavers in it and it was a pain. What is the best way to get rid of this weed in winter wheat? A: I can’t think of a redeeming quality for cleavers, although apparently the fruit is considered one of the best substitutes for coffee (Malik […] Read more
Pre-plant applications of dicamba at the high rate and to emerged fleabane rosettes have provided the most effective control of glyphosate-resistant Canada fleabane (left) compared to an unsprayed strip (right) when planting Xtend soybean varieties. A followup, post-emergence application of dicamba may be necessary when new seedlings have germinated following crop emergence.

Pest Patrol: Control of Canada fleabane

#PestPatrol with Mike Cowbrough, OMAFRA

By
Reading Time: 2 minutes Q: Canada fleabane has shown up in various places on our farm this year. I assume it is glyphosate resistant. Do I have any other options for soybeans other than Xtend beans? A: Yes, research conducted by the University of Guelph (Ridgetown Campus) has shown that the addition of Eragon LQ (30 ml/acre) + Sencor […] Read more
