“Herbicide layering” looks to be an effective approach to managing hard-to-control cleavers in pulses. As Eric Johnson, weed scientist at the University of Saskatchewan, explains in this Pulse School episode, herbicide layering is the application of different modes of action sequentially. It usually involves a pre-seed soil-applied herbicide, such as sulfentrazone, ethalflurolin or pyroxasulfone, ,… Read More

This year, the organizers of the Crop Diagnostic School in Carman, Manitoba, decided to do something a little old-school. “We decided to demo soil-applied herbicides here at the farm this year for the Diagnostic School, in part because we’re seeing an increased use in the products,” Jeanette Gaultier explains in the following interview. Gaultier (who may or… Read More

Pulse growers looking for control of grassy and broadleaf weeds will have new options from Syngenta Canada. The first is Nelatic pulse herbicide, a pre-mix formula that combines imazamox and bentazon for systemic and contact control of grasses and broadleaf weeds found in Western Canada field peas. Nelatic offers built-in resistance management support with two… Read More

Common ragweed’s ability to resist the control efforts of different herbicide groups continues to grow across Ontario. Last winter, University of Guelph weed scientist Dr. Peter Sikkema confirmed the presence of Group 14 resistance in common ragweed, making the broadleaf pest resistant to enzyme inhibitors, including branded weed control products such as Reflex and Blazer,… Read More

Pop quiz: do dry conditions automatically mean a dialling back of nitrogen rates on corn? This is a tricky question to answer as very dry conditions for prolonged periods can impact yield potential, but dry conditions also mean nitrogen is less available to the plant, so it’s a tough call. For the answer to why… Read More

Wheat and barley growers in Western Canada have a new herbicide to aid in the fight to control troublesome weeds, such as herbicide resistant kochia. Corteva Agriscience has announced registration of OnDeck herbicide, a product that provides post-emergent weed control for wheat (durum spring and winter) and barley farmers in the brown soil zones. OnDeck… Read More

The advent of herbicide-resistant weeds was bad enough, but the expansion of type, area, and mode-of-action resistance has left nearly no field untouched across the all regions of Canada. What can we do and how did we get here? To tackle that question, host Lyndsey Smith is joined by Dr. Charles Geddes, Agriculture and Agri-Food Canada… Read More

Most prairie growers know that adding another herbicide to their spring glyphosate application pays big dividends. First, they’ll see better and more consistent weed control. Second, starting with a clean field helps protect yield potential and third, having another mode of action (or two or three) in the tank will help avoid resistance and thus… Read More

Waterhemp that’s resistant to multiple herbicide groups continues to march across Ontario, but growers still have options to control the weed. There’s also emerging proof that integrated management could help growers take the fight to the spreading yield robber, says University of Guelph weed scientist Dr. Peter Sikkema. At the Ontario Agricultural Conference earlier this… Read More

Fungicides are integral for preventing disease in many pulse crops, however, just like how weeds have become resistant to certain herbicides, diseases can become resistant to commonly-used fungicide chemistries. The majority of pulse fungicides on the market in Western Canada contain a Group 11 — the category of fungicide most likely to be overcome by… Read More

Whether you’re a first-time lentil grower or an experienced farmer, using a complete-solution herbicide is key to maximizing yield. India has dropped in-bound tariffs on lentils which means lentil acres could be more profitable this year. Lentils, however, are not the easiest crop to grow. One of the key problems for growers is a lack… Read More

Wheat growers looking to manage resistance without compromising their crop rotation have a new herbicide to add to their management toolbox. Syngenta Canada has launched Erebus Xtreme, a grass and broadleaf cereal herbicide that combines Group 2 and Group 4 active ingredients in a pre-mixed liquid formulation. When using Erebus Xtreme, Syngenta says cereal growers will be able to effectively… Read More
