Managing herbicide resistant weeds

There may be snow on the ground, but Joe Armstrong, Dow AgroSciences field scientist says it isn’t too early to start thinking about weed management.

“Early season weed control is important regardless of the crop, but in a crop like soybeans, eliminating that early season weed competition is what sets you up for success for the rest of the year,” he says.

Armstrong tells Brownfield, weed management is critical in weeds like waterhemp, giant ragweed, marestail and Palmer Amaranth or Palmer Pigweed, which he says continues to creep further into the Midwest. “One of the best ways to manage herbicide resistant weeds is to get after them before they even germinate and emerge from the soil,” he says.  “That’s where that pre-emergence timing is so important.”

And, Armstrong adds, that’s where a product like Sonic herbicide is beneficial to growers.  “It has two herbicide modes of action,” he says.  “It’s going to give you a one-two punch when it comes to weed management – particularly for herbicide resistant weeds,” he says.  “That will help you control those weeds early in the season when they’re most susceptible.”

And give farmers another mode of action later in the season if needed.
