Applicators need relevant and timely information regarding chemical applications for the best performance.

Better labels

This new initiative aims to create crop protection labels producers will actually want to use to make spraying decisions

It’s a familiar spot to find yourself in. You want to spray a new product. Or maybe you want to tank mix two chemistries that you’ve never sprayed together before. The crop is ready, the sprayer is set, but now you see there are label questions about specific rates, ground speeds, buffer zones, clean-out procedures […] Read more

Pest Patrol: Weed control in identity-preserved, non-GMO soybeans

#PestPatrol with Mike Cowbrough, OMAFRA

A decade of public research trials evaluating weed control in non-GMO soybeans at the University of Guelph has demonstrated that the key to success is to start with a soil-applied herbicide program that has three or more different modes of action. In Ontario, there are a number of common weeds (e.g. common ragweed, lamb’s-quarters, foxtail […] Read more

Pest Patrol: The continuing fight against glyphosate-resistant Canada fleabane

#PestPatrol with Mike Cowbrough, OMAFRA

Glyphosate-resistant Canada fleabane is found in 30 counties across Ontario and can cause yield losses exceeding 50 per cent in both corn and soybeans. Since there are only a few other herbicides that are effective at controlling it, this glyphosate-resistant weed has been one of the most troublesome weeds in Ontario. So, what if you […] Read more

U.S. appeals court orders EPA to ban pesticide said to harm children

New York | Reuters – A divided federal appeals court on Thursday ordered the U.S. Environmental Protection Agency to ban a widely-used pesticide that critics say can endanger children and farmers. The 2-1 decision by the 9th U.S. Circuit Court of Appeals in Seattle overturned former EPA administrator Scott Pruitt’s March 2017 denial of a petition by […] Read more

Pest Patrol: New herbicide names may not mean new chemistry

#PestPatrol with Mike Cowbrough, OMAFRA

Q: Do I have new opportunities in weed control in 2018? A: This is the question I’ve been asked a lot this past winter meeting season, and one I always struggle to answer. There are some legitimately promising concepts being tested such as robotic weeders (Figure 1 at top) and weed seed destruction tools, but […] Read more


More than the cost of herbicide, growers need to consider how the cost of yield losses will affect future cropping plans.

Rotation refresher

More than crops, more than herbicides, it comes down to planning for success — with everything

The past two to three years have seen some encouraging signs of change for the better across Eastern Canada. Commodity prices are cyclically low yet corn, soybean and wheat yields have been trending upwards. There’s renewed interest in cover crops, and more growers have a renewed appreciation for soil health too, including a keener sense […] Read more

Re-evaluation of crop protection formulas has the potential to seriously restrict access to many tools farmers have come to rely on.

Troubling gaps within PMRA

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

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


Tom Wolf says “stronger, faster, higher” may not be the right approach for sprayers to provide maximum efficiency.

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

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

Soybean is more tolerant and resilient when it comes to early weed interference, compared to corn.

The challenge of early weeds in soybeans

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

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
