Pre-seed burnoff: Glyphosate alone or tank mix?

Growers often see a clear economic benefit from a pre-seed burnoff of weeds, especially if winter annuals and perennials are growing strong and seeding is still a few days or weeks away. The pre-seed burnoff stops weeds from taking up moisture and nutrients the crop could use.

Before spraying, check the weeds present and their sizes. Then look at the preseed burnoff options ahead of canola to see which options will best manage those weeds. Ultimately, another group with your glyphosate will help combat difficult weeds. Multiple groups in one pass have been shown to delay herbicide resistance – but the tank mix has to be effective. Add a group that will work on the target weeds, including consideration for potential herbicide resistance within that weed population.
