Research Emphasis

  • Conduct innovative research that will lead to reduction in herbicide reliance,
    expenditures, and usage or improve weed management efficiency in crops in Arkansas,
    providing alternatives to those herbicides that pose the greatest environmental risks.
  • Modeling temporal weed emergence;
  • Population dynamics of weeds in agricultural systems;
  • Modeling growth and development of important weeds;
  • Assessing weed populations for herbicide resistance;
  • Evaluating short- and long-term impact of production practices on weed species shifts
    and profitability;
  • Quantifying the diversity and composition of glucosinolates produced by Brassicaceae
    plants from around the world;
  • Assessing the use of synthetic isothiocyanates as replacements for methyl bromide.
