Waterhemp Beware: Multiple Modes of Action Deliver Control
Missouri: Growers in Clarksdale and Pattonsburg, MO, named waterhemp as one of their toughest weeds in corn. Waterhemp is difficult to control because it:
- Germinates throughout the season
- Grows up to one inch per day
- Produces up to one million seeds per plant
Left uncontrolled, a few waterhemp plants can easily become hundreds or thousands of waterhemp plants in subsequent seasons.

Managing difficult weeds like waterhemp requires herbicides with multiple, effective modes of action. Multiple, effective modes of action ensure that corn fields stay clean and remain clean throughout the season, protecting yield and the long-term viability and profitability of your farm.

We recommend Acuron® corn herbicide to control tough weeds like waterhemp. Acuron controls more than 70 broadleaf weeds and annual grasses, even resistant biotypes, with its combination of 4 active ingredients and 3 effective modes of action (Groups 5, 15 and 27). One of its active ingredients, bicyclopyrone, complements mesotrione and works in conjunction with atrazine and S-metolachlor to deliver long-lasting residual weed control. A wide window of application, from 28 days pre-plant up to 12-inch corn, provides the additional benefit of flexibility.
