With resistant weed control far and away the issue of greatest importance to ag retailers serving corn farmers, AMVAC has a wide portfolio of herbicides to help address weed resistance in corn – including Impact Core® and Sinate® Herbicide, both introduced to the market for 2021.

Impact Core provides control of emerged grass and broadleaf weeds with punishing takedown and lasting residual. It provides the proven power of topramezone in Impact® Herbicide and an industry-leading level of acetochlor to control the toughest weeds and grasses. Impact Core is Strong to the Core™.

Sinate postemergence corn herbicide controls herbicide-resistant and important driver weeds in LibertyLink® corn with outstanding crop safety. The powerful one-two punch of Impact and glufosinate provides punishing efficacy in the fight against herbicide-resistant weeds like waterhemp, Palmer amaranth, and giant ragweed. Sinate is Gentle on LibertyLink Corn, Wicked on Weeds™.

Rounding out AMVAC’s full lineup of corn herbicides are:

• Impact Herbicide – a powerful force labeled for postemergence use in all corn types that offers outstanding control of emerged broadleaf weeds along with remarkable grass control. It is The Standard in Corn Safety®. Impact has received federal EPA approval allowing expanded control of several weeds and extends Impact’s flexibility to more application situations.
• ImpactZ® Herbicide – a premix of two modes of action in one easy-to-use formulation for control of emerged broadleaf weeds and grasses.
• Hornet® Herbicide – a preferred tank-mix partner for postemergence control of glyphosate-resistant and key hard-to-manage broadleaf weeds like giant ragweed, cocklebur, and sunflower.
• Assure® II Herbicide – a postemergence grass herbicide formulated to protect a wide variety of crops including Enlist® corn hybrids by controlling a broad spectrum of problem grass weeds.

“In a time of continuing concern about weed resistance, corn farmers are always on the lookout for a combination of solutions to ensure they achieve the best weed control they can,” said Nathaniel Quinn, AMVAC Marketing Manager for Corn, Soybeans, and Sugar Beets. “AMVAC’s wide corn herbicide portfolio can help corn farmers address a greater number of weed control challenges including herbicide-resistant weeds.”
