Final words on dicamba

The big concern for herbicide companies is to keep Xtend technology for years to come

Reading Time: 4 minutes In farming circles, 2017 may be remembered for a profound addition to our technology with the launch of the Roundup Ready 2 Xtend soybean system and its companion herbicides, XtendiMax with VaporGrip technology and Engenia. Long anticipated, the Roundup Ready 2 Xtend Crop System brings with it the potential to solve many issues with glyphosate-resistant […] Read more

Treated and untreated soybeans at Ridgetown, about a week after application. Plots were 30-inch centres, treated as per label instructions at the right stage for application, and under very dry conditions.

The Xtend balancing act

Dicamba-resistant technology works, but it’s not simple and it requires more learning than glyphosate-tolerant systems

Reading Time: 5 minutes The 2016 growing season saw the advent of a new technology — Roundup Ready 2 Xtend soybeans, along with its herbicide companion, XtendiMax. The technology had been anticipated for more than five years, particularly by growers in the southern U.S. where resistant weed species and continual use of Roundup Ready soybeans and cotton have been […] Read more

EU chemical agency says glyphosate not carcinogenic

Reading Time: 2 minutes Helsinki | Reuters — Glyphosate, the key ingredient in Monsanto’s Roundup herbicide, should not be classified as a substance causing cancer, the European Chemical Agency concluded on Wednesday, potentially paving the way for its licence renewal in the EU. A transatlantic row over possible risks to human health has prompted investigations by congressional committees in […] Read more

Monsanto ghostwrote Roundup studies, plaintiffs in U.S. suit say

Reading Time: 2 minutes Reuters — Employees of Monsanto ghostwrote scientific reports that U.S. regulators relied on to determine that a chemical in its Roundup herbicide does not cause cancer, farmers and others suing the company claimed in court filings. The documents, made public Tuesday, are part of a mass litigation in federal court in San Francisco claiming Monsanto […] Read more

Pest Patrol: How do I get better control of lamb’s quarters?

#PestPatrol with Mike Cowbrough, OMAFRA

Reading Time: 2 minutes Lamb’s quarters has consistently been identified as the most abundant and most problematic weed affecting field crop production in Ontario. Yet the Pest Management Regulatory Agency database contains hundreds of herbicides that list lamb’s quarters as either suppressed or controlled. It’s safe to say there is an arsenal of products available to farmers, but our […] Read more

Rebate roundup for Eastern Canada

A quick glimpse at programs and opportunities available to growers for 2017

Reading Time: 6 minutes With the planting season just weeks away, we’re putting together a “Rebate Roundup” for eastern Canadian growers with our overview of the rebates offered by industry. Some of the companies contacted for our new annual “Rebate Roundup” feature say they don’t offer rebates — they prefer to stick to simple prices. Other farm input suppliers […] Read more


Mowing that patch before it went to seed might have been a better strategy that using an ineffective herbicide.

The more you spend, the less they work

If you want to keep using herbicides, give them an occasional rest and try a winter cereal or a heavier seeding rate

Reading Time: 3 minutes Neil Harker says that when you no longer have the big hammers in the tool box, it’s time to use the little ones. For the Agriculture and Agri-Food Canada (AAFC) weed scientist, wild oat herbicides are the big hammers, and the little ones are integrated weed management practices. Harker says that although western Canadian producers […] Read more

Goodbye glyphosate?

A flood of cancer suits in the U.S. threatens to topple farmers’ most valuable herbicide

Reading Time: 6 minutes Last September I warned readers of a growing public backlash against glyphosate herbicide, and I wrote of the co-ordinated attack on glyphosate by Avaaz, an online activist community that is claiming credit for the refusal by European regulators to renew the licence for glyphosate, instead only granting an 18-month extension to the expiring licence. But […] Read more

Pest Patrol: Xtend soybeans, spray drift and controlling glyphosate-resistant fleabane

#PestPatrol with Mike Cowbrough, OMAFRA

Reading Time: 2 minutes I want to plant Roundup Ready 2 Xtend soybeans this season to control my glyphosate-resistant Canada fleabane. But I keep hearing about the increased risk of drift with the dicamba-based herbicides. Is this fear mongering, or do I need to pay special attention when applying herbicides containing dicamba? We can learn a lot about the […] Read more

Pest Patrol: Enlist vs. Extend

#PestPatrol with Mike Cowbrough, OMAFRA

Reading Time: 2 minutes What is the difference between Enlist and Roundup Ready 2 Xtend soybeans, and how good are they at controlling glyphosate-resistant weeds? The key selling point of each new seed system is that they have tolerance to specific “auxinic” herbicides that traditionally have been used to control weeds in corn and cereals, and in theory should […] Read more
