“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 »

The Potential Role of Pyroxasulfone in Managing Foxtail Barley
Foxtail barley, or Hordeum jubatum, is a perennial bunchgrass with good tolerance to both salinity and spring flooding. Because of its relatively shallow root system, foxtail barley is quite susceptible to tillage as a management tool, however, due to the shift to low-till or no-till cropping techniques, this method isn’t always an option. Increasing seeding rates and… Read more »
Pulse School – Dealing with Herbicide Resistance in your Pulse Crops
Weed control in pulse crops is an area that has to be managed well in order for your crop to reach its potential. Pulse crops are not very competitive once put into the ring with invasive weed species. While they’re not exactly the 98-lb weakling of the agricultural world, they do need the playing field… Read more »
Pulse School – Pulse Management – The Weed Free Period, Seeding Rates & Dry Down Products
Spray timing, plant population and desiccants are very important elements to manage when it comes to weed control and the proper development of your pulse crop. According to Weed Biologist Eric Johnson of Agriculture & Agri-Food Canada, producers should start to plan weed control 2 to 3 years ahead. What that means is that in… Read more »
Canola School – The Relationship of Chem Fallow and Glyphosate Resistance
The issue of herbicide resistance is something producers will have to continue to be vigilant about. Careful consideration needs to go into the “when” “how” and “what” to use of your individual weed control strategy. That strategy in turn needs to be balanced with a good sense of corporate responsibility about producer issues like herbicide… Read more »
