My research program has two major focuses: 1) evaluation of herbicides for use in turfgrass management, and, 2) weed genomics and herbicide resistance. Synthetic herbicides are the most widely used method of weed control in turfgrass management. New herbicides are being developed to replace older herbicides that have problems with environmental, human, and other non-target toxicity. New herbicide chemistries have lower active ingredient use rates per area, are more targeted toward plant physiology, and have less chance of non-target contamination. In general, I conduct research evaluating turfgrass species tolerance and effectiveness of herbicides in controlling major weeds in Alabama. One specific research focus is controlling annual bluegrass in golf course turfgrass. Annual bluegrass is one of the most problematic weeds in golf course turf, reducing aesthetic quality and playability. New herbicides currently being tested could reduce triazine herbicide (atrazine, simazine) use, materials which have been implicated in amphibian reproductive malformations. Also, research is focused on control of bermudagrass (Cynodon dactylon). Bermudagrass, while an excellent turfgrass species, is also one of the state’s worst weeds in turfgrass and agriculture in general. Bermudagrass control is difficult because few selective herbicides are available and control can take up to two to three years. My research has focused on new chemical control measures for bermudagrass, alternative soil sterilization techniques, and the influence of non-chemical management practices.
