Pest Patrol: The importance of doing a ‘jar test’ with fertilizers and herbicides

#PestPatrol with Mike Cowbrough, OMAFRA

Reading Time: 4 minutes Each year I get more questions about mixing the liquid fertilizer, ammonium thiosulphate (ATS), with herbicides. With reductions in atmospheric sulphur deposits, Ontario research has shown positive yield responses in some crops when sulphur fertilizers are applied, so it makes sense that farmers are looking at ways to add sulphur to their crop in an […] Read more

Robotic weed management takes to the fields

The potential for cost savings and precise control is enormous

Reading Time: 6 minutes Extraordinary. Revolutionary. Game-changing. Those are just some of the adjectives being used to describe robotic weed management, a technology that is generating considerable anticipation based on the initial research into its benefits in a row-crop environment. The list of key players and systems includes WEEDit, Xarvio, Bosch, Agrifac and Einböck. And the potential is large […] Read more


Competition Bureau probing big ag chem companies

Probe to look at firms' response to FBN's arrival in Canada

Reading Time: 2 minutes Reuters — The Canadian Competition Bureau said on Thursday it was investigating certain agriculture companies for alleged anticompetitive practices over allegations of trying to block an online farm-supply startup from doing business in Western Canada. The regulator did not provide details on specific companies involved in the probe, but documents filed on Jan. 30 in […] Read more

Trump administration scales back U.S. water protections

Reading Time: 2 minutes Washington | Reuters — The Trump administration finalized a rule on Thursday to pare back the types of waterways protected from pollution under federal law, easing burdens on industries such as agriculture and mining but angering environmental groups. The Navigable Waters Protection Rule could win political points ahead of the November election for Republican President […] Read more


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

#PestPatrol with Mike Cowbrough, OMAFRA

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

PHOTOS: Pest Patrol: Purple deadnettle and henbit control in winter wheat

#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
