Research

My research program focuses on developing sustainable weed management programs in agronomic crops, especially sugarbeet, winter wheat, corn, and dry beans. Recent research projects include:

  • long-term management of jointed goatgrass in imidazolinone-resistant (Clearfield) winter wheat
  • synergistic herbicide combinations for management of feral rye
  • new herbicide options in proso millet
  • effect of long-term glyphosate use in glyphosate-resistant (Roundup Ready) cropping systems,
  • use of ethofumesate in glyphosate-resistant (Roundup Ready) sugarbeet,
  • management of volunteer corn in dry beans and sugarbeet.
