Reducing early season weed pressure is key to reducing competition from weeds that can rob moisture, nutrients and sunlight from your crop, which can negatively impact crop yield.
University of Saskatchewan research shows that where weed competition is significant, an early burnoff application can have a greater influence on crop yield than an early seeding date.
Herbicide resistance costs Canadian growers an estimated $1.1 to $1.5 billion annually due to increased herbicide use and decreased yield and quality.
In Canada, 46 per cent of all glyphosate applied in 2015 was at pre-plant/pre-emergence. In Western Canada, 69 per cent of that glyphosate was applied alone, increasing the risk of selection of resistant weeds. 
When it comes to preventing herbicide resistance, using tank mix partners can be more effective than alternating single-mode applications. Selecting an add-in with a different mode of action is one of the most effective ways to prevent the development and spread of herbicide resistance.
Pre-seed timing is one of the easiest opportunities to include a tank mix partner in your herbicide application and is an excellent time to diversify your herbicide program.
The team of agronomic experts at P&H are here to help you find the best tank mix options to help you start your growing season with a clean field and prevent the spread of herbicide resistance.
Always read and follow label instructions including application rates, precautions and restrictions.
With tighter rotations leading to increased issues such as blackleg and clubroot in canola, we need to do our part to make sure glyphosate-resistant weeds don’t become the next hurdle for canola growers.
For your pre-seed herbicide application before canola, consider a tank mix partner such as:
Adding diversity to your herbicide program is an important step in controlling resistance. When planning your pre-seed burndown before planting wheat or barley, make sure you include a tank mix partner with your glyphosate. The agronomy team at P&H can help you identify which add-in is the best fit for your farm.
Weeds that emerge prior to or at planting are the most competitive with corn and soybeans. Early competition from weeds within the first weeks after planting can have a significant impact on yield potential. Reduce that competition by planning a pre-seed burndown.
