If you’re evaluating weed-control options in soybeans this season, take a look at new Tendovo herbicide from Syngenta.
It is now approved for use by the U.S. Environmental Protection Agency (EPA) and ready to tackle tough weed issues, notes Pete Eure, herbicide technical product lead for the company.
Eure says Tendovo is a three-way premix that offers early-season preemergence weed control that “stops early-season weeds without slowing down soybean growth.”
He highlighted a variety of features and benefits for the product in a recent webinar and noted the herbicide offers:
- Robust rates of S-metolachlor, metribuzin and cloransulam-methyl in a convenient ZC formulation.
- Broad-spectrum residual control of 70 small- and large-seeded broadleaf weeds as well as grasses, including Palmer amaranth, waterhemp, giant ragweed, common ragweed, nutsedge, kochia, marestail and lambsquarters.
- Excellent crop safety across soil types and environments in all regions of the country.
- Flexibility for use across tillage systems and compatibility with non-selective burndown herbicides.
- Regardless of the soybean trait platform, the product protects soybean yield by providing early-season weed management when used preplant or preemergence.
Syngenta recommends using Tendovo as part of a planned, two-pass program, which will help delay the development of weed resistance and protect yield potential, adds Dane Bowers, herbicide technical product lead for the company.
“It’s really important that we utilize best management practices, so we can prevent future development of resistance,” Bowers says. “One of the things we need to think about is considering using overlapping residual herbicides to prevent weeds from emerging. Germinating seedlings are much easier to control than those weeds that have already emerged.”
In addition, Bowers encourages farmers to start this season with clean fields—even if that requires using some tillage.
“We want to start with a clean seedbed wherever possible,” he says. “We don’t want to have large weeds in a field when we go to plant and then have to come in and clean those up.”
Using all the available tools in your toolbox to control weeds is more important than ever this year, adds Larry Steckel, University of Tennessee Extension weed specialist.
He cites herbicide supply and cost as major concerns. In addition, he says pigweed species, Palmer amaranth in particular, are exhibiting resistance to auxin herbicides in Tennessee and Arkansas, and also in parts of Illinois and possibly Indiana.
“Integrated weed management is more important than ever – not just relying on a post herbicide in particular,” Steckel says. “We need to be looking at a lot of different tactics and putting them all together in the field.”
