Agricultural plastics not part of federal ban

The federal government’s plan to halt Canada’s consumption of single-use plastics such as shopping bags, straws and stir sticks over the next couple of years won’t extend to farm chemical containers and grain bags. Cleanfarms, the national industry stewardship body operating waste management and recycling programs for agricultural packaging, said Thursday that plastic products such […] Read more

Several factors relating to water quality can affect product performance in the field, often to the detriment of the crop.

Keep an eye on water quality

Water can play havoc with spray performance, especially with the rise in tank mixing

The 2019 growing season is now within sight and with it, another season’s worth of herbicide, fungicide and insecticide applications. Given the challenges that can arise with sprayers and their products, it’s worth revisiting the subject of water quality and the potential impact of factors such as temperature, hardness and pH on product performance. With […] Read more


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
