Managing your pre-seed burnoff in a tight market

The research and experience in the field is unequivocal: The right pre-seed burnoff is critical to guarding yield potential.

Lack of moisture was a big challenge in 2021. Among other things, a pre-seed burnoff takes out weeds before they can rob the crop of soil moisture and nutrients.

Research also suggests that plants detect neighbouring plants by constantly analyzing the spectrum of light reflected from surrounding surfaces. When there’s competition from weeds early on, the crop will compensate by changing its growth pattern, throwing more energy into growing roots or branching out faster.

If your crop isn’t clean through the early, critical weed-free period you’re throwing away significant yield potential. But the odds are stacked against achieving that clean field when weeds like kochia, volunteer canola, flixweed, lamb’s-quarters, redroot pigweed and cleavers are present.

Aim for a quick, enhanced burnoff of the hardest-to-control weeds

A pre-seed burnoff is key to guarding yield in canola, pulse and cereals acres. Aim® EC herbicide has become the go-to tank-mix partner for the hottest burnoff. It has a convenient concentrated formulation and unique Group-14 activity.

Finding a way to maximize your glyphosate application is important for resistance management and weed control.

Aim EC herbicide also has a long list of tank-mix partners including Express® brand herbicides for faster burnoff and an even longer list of weeds. It can also be tank-mixed with 2,4-D, Bromoxynil, and MCPA when you need increased control of GT canola or larger volunteer canola.

Adding Aim EC herbicide to a tank-mix with an Express® brand herbicides offers some additional savings through the ACE Resistant Weeds program. The Group 14 mode of action in Aim EC herbicide speeds up contact control, showing faster results. The Express herbicide brings systemic activity for complete control. When you use Aim EC herbicide and Express brand herbicides in a tank mix, you earn a $2.50 rebate. Ask your retailer more for information.

Pre-seed burnoff in canola

The Canola Council of Canada says growers should rely on early weed control. According to the Canola Council, “Canola that gets off to a good start with weed competition reduced early in the season rarely sees an economic benefit to a second in-crop application of herbicide.”

Winter annuals like cleavers are best controlled in the pre-seed window, especially plants that germinated in the fall and were able to establish a large root system. They are best controlled when they are as small as possible in the spring. Volunteer canola is another weed you want to eliminate early. Those plants don’t contribute to yield and, since they don’t have a seed treatment, they can introduce seedling diseases and increase flea beetle pressure.

Also, the Canola Council says a tank-mix partner is a way to improve weed control and reduce selection of herbicide-resistant weeds.

Pre-seed burnoff in cereals

Researchers and producers now know the value of early weed control in getting a crop established in the spring. Wheat producers have learned that even a slight growth advantage on weeds really benefits the crop.

Glyphosate is often used as a pre-seed burnoff with another product added as a tank-mix to control weeds that glyphosate misses. The right tank-mix partner can add extended control to get the crop through the critical weed free period and reduce the risk of weed resistance.

The research and field-scale results are undeniable: A pre-seed burnoff is critical to protecting yield.
