Panhandle researchers are conducting 16 field trials this year to test six new herbicides and various management strategies to help producers control surging Palmer amaranth populations in sugarbeets and dry beans.
Results of a 2020-21 study investigating the impact of uncontrolled Palmer amaranth in dry beans. Using pinto beans, researchers were able to pinpoint yield loss and potential seed production of Palmer amaranth.
Results of a study evaluating the efficacy and crop safety of labeled post-emergence herbicides to control velvetleaf, a major agricultural weed in Nebraska that reduces yields in popcorn if not controlled.
Corn is the most common rotational crop planted the year before dry bean in western NE. However, herbicide programs must be chosen with foresight as many corn herbicides can injure dry beans the next season due to crop rotation restrictions.
In order to calculate an herbicide resistance risk score, four years of crops need to be entered. Once herbicides are chosen for all four years and a weed species is selected, the model will calculate an herbicide resistance risk score for each herbicide site of action that was selected.
