Although food labels are generally intended to inform consumers, some food labels such as non-GMO labels continue to cause confusion and debate in the marketplace. Building on earlier work, the objective of this study was to gain insights into the connection between consumer responses to...
The reduction of crop yield and quality, and the increase in additional weed management expenditures were estimated to cost Manitoba farmers $77 million annually. The confirmation of herbicide-resistant weeds continues to grow in Manitoba, across the Prairies, and worldwide. As of 2025 in Canada, 77 herbicide-resistant...
Mowing and chaff mulch were the most effective and least costly non-herbicide kochia patch management treatments. Kochia herbicide resistance has become widespread on the Canadian Prairies. Kochia populations have now been identified as having resistance to Groups 2, 4, 9 and 14, with some Group 2+4+9...
Light-activated sensor-controlled sprayer reduced the overall chemical use by 23% to 55% and resulted in cost savings of $2.36/ac to $12.48/ac ($5.83 to $30.83/ha) across herbicide treatments for kochia and prickly lettuce control. In recent years, light-activated sensor-controlled (LASC) sprayers have become more popular with custom...
Early maturing crop rotations that included winter wheat had reduced wild oat populations compared to normal or late maturing rotations. This was likely because of increased crop competitiveness, rotational diversity and possibly harvest weed seed control. The evolution of herbicide-resistant wild oats has made wild oat...
Two grower submitted samples were confirmed to have Group 14 PPO inhibitor-resistant kochia from the RM of Newcombe in Saskatchewan and Forty Mile County in Alberta. Dose response bioassays confirmed high resistance to foliar applied Group 14 active ingredients saflufenacil and carfentrazone in a kochia population...
Dose response bioassays confirmed high resistance to foliar applied Group 14 active ingredients saflufenacil and carfentrazone in a kochia population from Kindersley and two populations from North Dakota. Herbicide-resistant kochia has become a serious problem for Prairie farmers over the last two decades. Currently, all kochia...
Fine-tune carfentrazone-ethyl application to kochia at a weed growth stage of up to 5 cm with no branches to help avoid nonlethal herbicide dosing, which can help to reduce the risk of non-target site herbicide resistance evolution. Kochia is one of the most troublesome weed on...
Combine harvesting spread wild oat seeds up to 475 feet (145 m) at population levels of more than 1 seed per square foot (10 seeds/m2). This compared to less than 1 seed/ft2 at 150 feet (45 m) with chaff collection. Wild oat distribution is typically patchy...
Two weeks after metribuzin treatment, chickpea mortality was 25% at the full label rate, and 56% for the 2X rate. Accumulated chlorosis and necrosis were similar for the control and 1/2X rate. The 1X rate significantly reduced pod production by 75% and was similar to...
