| Abstract/Contents: | "Herbicide resistance has been used quite successfully as a tool for the control of weeds in various agricultural crops. Most often herbicide resistant cultivars have been developed using genetic modification (GM). However, the commercialization of GM herbicide resistant turfgrass has thus far been unsuccessful. A tissue culture technique was used as a non-GM approach to develop a sethoxydim resistant Agrostis stolonifera. This sethoxydim resistant bentgrass line, known as SR1-A, was confirmed to contain a mutation (Ile-1781-Leu) known to confer the resistance to Acetyl coenzyme A carboxylase (ACCase) inhibiting herbicides. Plant material of this line was propagated and a whole plant herbicide dose response experiment was conducted. The experiment included two lines, SR1-A and PennA4, a resistant and susceptible control, respectively. Three ACCase inhibiting herbicides were included at eight rates ranging from 0-3200 grams active ingredient per hectare(g ai ha-1). Each herbicide block was a completely random design replicated four times. Visual herbicide injury percentage ratings were taken at 21 and 28 days. The SR1-A line had significantly lower injury at 400 g ai ha-1 and above rates for all three herbicides at 21 and 28 days at alpha=0.05. Also the 21 day I20 values (amount of herbicide to cause 20% injury) were greater than 3200 g ai ha-1 for SR1-A compared to values ranging from 74-180 g ai ha-1 for the susceptible PennA4. The resistant SR1-A bentgrass has great potential for use in an herbicide resistant weed control system in turfgrass." |
