the rate and amount of crop growth as well as salability (Berchielli-Robertson, Gilliam, and Fare 1990; Norcini and Stamps 1994). Weed management in nursery production is most effectively achieved through preventative practices, primarily with preemergent herbicides (Gallitano and Skroch 1993; Gilliam et al. 1990).
