Accomplishments

Accomplishments: The NCERA 221 multi-state research project on Turfgrass and the Environment has continued to make progress towards collaborative projects and the objective associated with the working group.   NCERA 221 Objectives: <ol> <li>A search of the CRIS database identified much turfgrass sustainability research being conducted by NCERA 221 members… In addition, these, and other NCERA 221 members conduct collaborative and institutionally based turfgrass sustainability research that will advance our understanding of how to maintain the millions of acres of turfgrass in the region in more sustainable approaches. </li> <li>Members of NCERA 221 will deliver the findings of this research to academic, professional, and citizen stakeholders through a variety of approaches including academic publications, field days, printed media, and online information.</li> </ol> Collaborative Research Projects: <ol> <li>Regional Roadside Turfgrass Evaluation Program. Numerous projects have been initiated and completed investigating turfgrass varies on various roadside conditions. These projects have been conducted in conjunction with Department of Transportation and participating universities. Research projects have allowed universities to recommend varieties for DOT roadside blends in urban and rural areas. Evaluations included turfgrass varieties, salt tolerance, establishment and roadside stability for erosion control. Development of online educational tools for contractors that are installing roadside turfgrass is currently being explored.</li> <li>Regional Weed Control Publication. A regional weed control publication for turfgrass professionals has been created to include 14 states. In 2017, 2,100 copies in total were printed. An overwhelming positive response to the publication was received for the 2nd year of this group effort. The 2019 edition is currently being edited and will include; minor text/ratings, cover photo, addition of new herbicides, addition of approx. two weeds in the identification section and addition of Maryland to the publication. Other completed project efforts include a Weed ID poster and the creation of a Turf Management Mobile Pesticide Recommendation website (turfpests.wisc.edu) by P. Koch (Univ. of Wisconsin).</li> <li>Organic Weed Control. 11-13 states including site outside of Maryland have been identified and research trials have been initiated to explore the weed control with organic products. The next treatment applications will be conducted mid-September. Data collection will continue through Spring 2019.</li> <li>Growth Potential Model Validation Project. Field studies across multiple universities have been conducted over the past could years to collect baseline data. Several plant growth regulator (PGR) growing degree day (GDD) models for turfgrass with collaboration at the University of Wisconsin and four other universities in the Southeast US have been created. Currently research is being conducted on the greenhouse and growth chambers to create models that are to be cross-referenced with field research data. Fertilizers, temperatures as well as clipping volume are being evaluated.</li> </ol> Please attached file for NERCA221's full report for Accomplishments and Impacts.

Brief Summary of Minutes

Brief summary of minutes of annual meeting: The 2019 NCERA 221 meetings were held June 24-26, 2019 at the University of Missouri, Columbia, Missouri. We achieved our goal for these meetings by continuing collaborations between researchers in the NCERA 221 working group. On June 25, 2019, the meeting started with three presentations. Topics covered included turf diseases and management strategies developed at the University of Missouri, integrating drone-based technologies to detect turf stresses, and an update of the regional organic weed control project. In the afternoon hours, the group travelled to St. Louis, which is about 2 hours away, and visited Busch Stadium and Budweiser Brewery. The following day NCERA held a business meeting, which started with updates on a numbers of collaborative projects within this group, including low-input sod production, fine fescue development project, and the regional zoysiagrass evaluation program. State reports followed the updates, before the administrative update and historian report. Before the meeting was adjourned at noon, our group also discussed new collaborative projects, including an organic herbicide evaluation project and possible replacement of glyphosate. Complete annual meeting minutes are also listed below.

Accomplishments

The NCERA 221 multi-state research project on Turfgrass and the Environment has continued to make progress on collaborative projects and the objective associated with the working group.   NCERA 221 Objectives: <ol> <li>A search of the CRIS database identified much turfgrass sustainability research being conducted by NCERA 221 members… In addition, these, and other NCERA 221 members conduct collaborative and institutionally based turfgrass sustainability research that will advance our understanding of how to maintain the millions of acres of turfgrass in the region in more sustainable approaches. </li> <li>Members of NCERA 221 will deliver the findings of this research to academic, professional, and citizen stakeholders through a variety of approaches including academic publications, field days, printed media, and online information.</li> </ol>   Collaborative Research Projects: <ol> <li>Regional Roadside Turfgrass Evaluation Program. Numerous projects have been initiated and accomplished aiming at improving turfgrass stands on various roadside conditions. This multi-state project involved turfgrass researchers at Universities in four other states (Wisconsin, Nebraska, Michigan, and New Jersey) is in its final year, studying a number of turfgrasses for performance on both rural and urban roadside sites. The roadside irrigation system research has found that it is practical to establish sod in these environments by the use of fire hydrants. An online course for roadside turfgrass installers that covers the basics of turfgrass management with a focus on roadside-specific challenges has also been developed from these projects. Subsequently, a new USDA-SCRI project, led by UMN with collaborators at UW-Madison, Rutgers, Purdue, Oregon St., and USDA-ARS Logan UT began in September 2017, focusing on fine fescue germplasm improvement.</li> <li>Regional Weed Control Publication. In the past year, this regional weed control publication, initiated in 2012, now has expanded to include 16 states with Maryland and North Dakota being the new additions. New weed species and new herbicides have been added to the new version of this publication, resulting a total of 118 weeds included. In addition to herbicides, PGRs were added to the new edition as well. An overwhelming positive response to the publication was received for this group effort. Over the past 7 years, Over 12,300 hard or electronic copies were purchased and distributed, and 76% of responses in a survey commented that this publication improved their weed control practice.</li> <li>Organic Weed Control. Relevant studies have been conducted in 10 states within this NCERA working group during both the spring and autumn of 2018 that evaluated the effectiveness of several different organic herbicides for the control of dandelion and white clover compared to a conventional herbicide standard. Our results indicated that autumn is the better time to use these products and that, while there was some variation in efficacy, some of the products tested were similar to control provided by the standard herbicide.</li> <li>Regional zoysiagrass evaluation project. Research done by K-State and Purdue (along with Texas A&M) evaluated more than 2,800 zoysiagrass progeny, all having a single parent in common that exhibited tolerance to large patch. Selected progenies were futher evaluated in several transition zone states for quality characteristics and large patch tolerance. From these evaluations conducted over several years, 10 progeny have been identified for further evaluation that have good quality and large patch tolerance that is superior to Meyer zoysiagrass.</li> </ol>
