The weed science program is many faceted. There are opportunities to conduct research in herbicide-soil interactions to limit herbicide contamination of off-site areas and to understand the fate of herbicides in the soil, vadose zone and aquifer. Understanding weed ecology in crop and rangeland systems is also an important component of the program. Nonchemical options for weed control including the use of crop rotation and biological control techniques also are developing as important part of the weed science program. Dr. Clay teaches the course, "Weed Science", that has a laboratory section to develop understanding of weeds, herbicides, and their fate in the environment.
