Raven Industries has joined AGCO and BASF as the newest Operation Weed Eradication coalition member, to support farmers in their weed control efforts. Operation Weed Eradication is an industry-wide mission with the goal of enlisting tough-minded farmers and industry leaders whose approach is that the last weed standing is the strongest, most capable and the… Read More
Glyphosate-resistant waterhemp was first identified in Ontario in 2014. Since that time the weed, which hails from the pigweed family, has spread across the province with confirmed sightings in 14 counties in 2019. To make matters more troubling, waterhemp resistance continues to grow beyond glyphosate, and now includes multiple resistance to Group 2, 5, 9… Read More
Do you need to manage herbicide-resistant weeds? Could you use more flexibility during the busy planting season? Does heavy weed pressure make it difficult to keep fields clean early in the season? These are all questions growers should be asking as they plan their 2021 soybean weed control programs, says BASF technical development manager Rob… Read More
It’s time for Day 3 of the virtual Ontario Diagnostic Days! This week, we’re joined by Dr. Peter Sikkema with the University of Guelph, and Mike Cowbrough, weed specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs. This episode focuses on weed management, specifically on glyphosate resistant Canada fleabane and waterhemp, and the… Read More
As of 2019, glyphosate resistant waterhemp has been confirmed in 13 counties in Ontario. Christian Willemse, a master of science student at the University of Guelph, under the supervision of Dr. Peter Sikkema, will continue a survey on glyphosate resistant waterhemp this fall as part of his master’s project. Farmers and agronomists are encouraged to… Read More
After wreaking havoc in the U.S. and parts of Ontario, herbicide-resistant waterhemp has arrived on the scene on the eastern side of the Canadian Prairies. Patches of the prolific weed — a cousin to Palmer amaranth — were found in multiple fields in five municipalities in Manitoba last year. In one case, over 30 acres… Read More
Earlier this year, Dr. Peter Sikkema, professor with the University of Guelph and his research team confirmed Group 14 resistance in waterhemp at multiple locations in Ontario. Sikkema’s research team, including graduate student Lauren Benoit, has also confirmed waterhemp with cross-resistance to Groups 2, 5, and 9, as well as 14. In this episode of the Resistance Management… Read More
If you’ve ever been frustrated by a weed’s seemingly amazing ability to survive and even thrive after being knocked back, cut down, or sprayed, this discussion is for you. You’re not imagining things — weeds really do have adaptations that make them harder to kill and allow them to spread faster and easier than desired… Read More
For all the talk of a late, late spring, we sure have caught up in a hurry. While there are areas hurting for moisture nearly across Canada, some regions have had near-ideal planting conditions and even a timely rain or two, post-seeding. What’s got croppers curious this week? Peter Johnson, host of Wheat Pete’s Word,… Read More
It’s not necessarily the happiest of discoveries, but it’s a first-of-its-kind discovery, nonetheless. Work out of the University of Guelph has confirmed Group 14 resistance in waterhemp at multiple locations in Ontario. What’s more, Dr. Peter Sikkema’s research team, including graduate student Lauren Benoit, has also confirmed waterhemp with cross-resistance to Groups 2, 5, and… Read More
Waterhemp has set down roots across Ontario, from Essex and Lambton County, and reports indicate it may have migrated as far east as Quebec. Controlling the invader poses several challenges for growers, says BASF agronomist Richard Anderson. The first problem is a high level of herbicide resistance. Some waterhemp is resistant to up to three… Read More
