| Abstract/Contents: | "Quinclorac, a synthetic auxin that possesses unique grass-in-grass selectivity, is especially beneficial in providing Digitaria spp. control. Digitaria spp. are considered one of the most problematic weeds in turf, and among Digitaria species, Digitaria ischaemum (smooth crabgrass), confounds this issue with the evolution of resistance to quinclorac. A potential resistant smooth crabgrass population, we refer to as "Tier17", was identified at the Auburn University Sports Surface Field Laboratory and a dose-response experiment was conducted to confirm its resistance status. An increasing rate of quinclorac (Drive XLR8) was applied to the putative resistant population and to a known susceptible population, referred to as "College". Percent injury ratings were taken at 7, 14, 21, 28, and 35 days after treatment (DAT) and above ground biomass was taken at 35 DAT. Based on the data collected, the Tier17 population was deemed resistant and utilized for further molecular studies." |
