The Environmental Protection Agency recently registered Syngenta’s Acuron GT, a post-emergence herbicide for use on glyphosate-tolerant corn. State registrations are pending. Acuron GT combines the active ingredients in Halex GT corn herbicide — glyphosate, mesotrione and S-metolachlor — with the active ingredient bicyclopyrone added. This helps helps Acuron GT provide enhanced post-emergence control of yield-robbing weeds and longer-lasting residual in ... Read More »

• By Daniel Stephenson •  Managing weeds in corn can be divided into three phases: preplant, in-crop and post-harvest, but I’ll save the post-harvest phase until later in the year. Preplant is otherwise known as burndown. We suggested applying a burndown herbicide four to six weeks prior to planting. Typically, glyphosate at 1 to 1.25 lb ae/A is the first ... Read More »

Weeds are the bane of most growers’ existence. In a growing class of “superweeds,” Palmer amaranth continues to frustrate farmers with its dogged resistance to commonly used herbicides. Research has shown that left unchecked Palmer amaranth can reduce corn yield by 91%. Different chemistries have been brought to market and enjoyed some control against the weed, yet many are no ...

Helm Agro US Inc. has received federal registration from the U.S. Environmental Protection Agency for Katagon, an HPPD premix herbicide for psotemergence use in field corn. It contains two modes of action — tolpyralate and nicosulfuron — with the added benefits of a low use-rate formulation, crop safety profile and a wide application window. When used as a tankmix with ... Read More »

As the 2020 corn-growing season draws to a close, Syngenta engaged university agricultural researchers from across the United States to analyze the agronomic challenges farmers encountered this season and offer tips on how they can best control weeds and preserve yields heading into 2021. Although weed pressures vary by geography, weed management fundamentals remain consistent throughout the United States. Researchers ... Read More »

• By Tom Barber • Weed control in Arkansas corn production has become more difficult over the past several years with the onset of glyphosate-resistant pigweed, marestail and ryegrass. Each of these weeds, if not controlled prior to planting, can rob corn of yield potential. To make matters worse, pigweed populations have been found resistant to six herbicide modes of ...
