Combine Clean Out Can Help Reduce Weed Spread

August 25, 2021
With increasing pressure from herbicide-resistant weeds such as kochia and introduced herbicide-resistant weeds such as Palmer amaranth and waterhemp, it is important to reduce spreading of weed seed. Doing a limited cleaning between fields and choosing which fields to harvest first can be an important factor in this endeavor.

Management of ALS-Resistant Palmer Amaranth and Waterhemp in the Panhandle

January 6, 2017
Palmer amaranth and waterhemp in the Panhandle are resistant to ALS-inhibiting herbicides. While control of these weeds in dry bean can be challenging, corn, irrigated small grains, and sugarbeet make good rotation options for control. A combined pre/post treatment strategy controls weeds in the early part of the season when crop yield is most impacted and weed species are most susceptible to control inputs.
