As much as companies have been communicating on stewardship, there are still issues in using newer technologies.

Are crop trait technologies simplifying your life, or complicating it?

Deciding how to use the technologies can turn into more of a challenge than deciding which of them to use

Reading Time: 6 minutes The arrival of a new herbicide-resistant technology is often greeted as an opportunity for growers and the industry. That isn’t really new. Roughly 30 years ago, Group 2 herbicides solved the problem of atrazine resistance, then LibertyLink and Roundup Ready technologies enabled growers to push beyond Group 2 resistance. Now that Xtend and Enlist systems […] Read more

Pest Patrol: Plan to manage waterhemp in 2020

Reading Time: 2 minutes Waterhemp has spread further across Ontario during the 2019 season and can now be found in eight counties (Bruce, Chatham-Kent, Essex, Haldimand, Lambton, Middlesex, Norfolk and Northumberland). A close relative of pigweed, waterhemp is a competitive annual broadleaf weed that has been found resistant in the province to four different herbicide groups (Group 9: Roundup, […] Read more


“We are in a complex herbicide and insect-tolerant landscape now,” says Drew Thompson of PRIDE Seeds.

The growing body of science for corn growers

There’s nothing easy about producing new traits and hybrids in corn, or about how to get the most out of them

Reading Time: 6 minutes When your parents got their start, farming was relatively uncomplicated. The farm season was pretty much divided into plowing, planting, cultivation and harvest. Weed management meant getting on top of quackgrass, Canada thistle and mustard, and soil organic matter was out-of-sight, out-of-mind. And transgenics was a word no one had ever heard. Some things make […] Read more

#PestPatrol with Mike Cowbrough, OMAFRA

Reading Time: 3 minutes Q: I’m seeing more henbit and/or purple deadnettle in my winter wheat crop. Should it be controlled, and how? A: Henbit and purple deadnettle are often discussed interchangeably because they look similar, are from the same genus (Lamium) and have similar emergence patterns (mainly in the fall, but henbit will also emerge in spring). Both […] Read more


Bayer cancels plans to sell U.S. crop product in 2020 over safety concerns

Reading Time: 2 minutes Chicago | Reuters – Bayer AG has scrapped plans for wide sales next year of a chemical that is intended to protect U.S. crops from yield-robbing worms, citing ongoing safety concerns. The decision is the latest setback for Germany-based Bayer following its acquisition of Monsanto for $63 billion in 2018. Bayer is separately battling thousands of lawsuits claiming Monsanto’s glyphosate-based […] Read more

U.S., Canada, 14 others slam EU farm product regulation at WTO

Reading Time: 2 minutes Geneva | Reuters — The United States and 15 other countries launched a broadside of criticism at the European Union on Thursday, saying its “hazard-based” approach to regulating pesticides and other “critical tools” used by farmers was damaging livelihoods worldwide. Their statement, submitted to the World Trade Organization, said the EU’s approach created great uncertainty […] Read more


Agricultural plastics not part of federal ban

Reading Time: 2 minutes 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

Reading Time: 5 minutes 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

Reading Time: 6 minutes 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

Reading Time: 2 minutes 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
