Outputs
Target Audience:The target audience inlcudes turgrass managers, forage and hay producers, vegetation managers, and farmers. Changes/Problems:Major changes are not necessary but an increased emphasis on preventing the development of herbicide resistance will be a priority. Herbicide resistance in turfgrass systems is not as prevalent as the general agricultural industry but herbicide resistance in increasing in turfgrasses and must be addressed in a more comprehensive manner. What opportunities for training and professional development has the project provided?Multiple training approaches have been utilized for clientele. They include an average of about 35 extension meetings per year. In addition, a turfgrass short course is offered yearly to help disseminate the research findings. Training for extension agents has occured on a regular basis. Presentations are also made at our annual turfgrass field day in August. Over 800 industry personnel and end users attend. Multiple annual publications are published that incorporate the research findings. The publications are readily available to end users at www.turffiles.ncsu.edu How have the results been disseminated to communities of interest?See previous section What do you plan to do during the next reporting period to accomplish the goals?Research trials will be initiated at our Turfgrass Field Laboratory on campus that will evaluate pesticide use that encompasses efficacy, environmental fate, and bioremediation of pesticide residues in soil and water. Funding will be primarily via our Center for Turfgrass Environmental Research and Education. Currently, one graduate student is being funded to investigate terrestial and aquatic plants to removed pesticides from soil and water. Reserach trials are also planned to help prevent further development of herbicide resistance in turfgrass weeds. This includes maximizing available herbicide chemistry to prevent repeated use of the same mode of action for weed management.
Impacts
What was accomplished under these goals?
Data from research trials have been posted on our turffiles website (www.turffiles.ncsu.edu). In addition, a turfgrass weed decision aid was developed from efficacy trials and placed on turffiles. Our turffiles website is the most visited educational website for turfgrass science and reaches a worldwide audience. In addition, a turf alerts section of turffiles has been established. When a turf alert is posted, those who have provided their email addresses will get a notification of the turf alert. This is routinely used for weed related issues. When a new weed invasion in documented, or other significant weed related issues occur, a turf alert is posted. Another great electronic tool is posting powerpoint presentations on turffiles for audiences to look at the latest reserach information presented to end users. In addition to turffiles, refereed journal articles are published as noted in a previous section.
