At the recent Trisociety meetings (The American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America ) in Phoenix, Arizona, several NC State turfgrass students received awards for competing in poster and oral presentation competitions. Congratulations to these outstanding students:

Title: Predict Atrazine Sorption: Meta-Analysis versus Experimental Study
Award and Division: Third place in the Soils and Environmental Quality Division
Summary: The research used meta-analysis approach as well as experimental study for atrazine sorption prediction, and found out that organic carbon is the best predictor globally and regionally. Meta-analysis and experimental study approaches complement each other and can be applied in environmental fate studies and pesticide risk assessment.

Title: Comparison of Color Parameters of Green Turf Colorants Applied to Bermudagrass
Division and Award: Second place in the Golf Turf Management of the CSSA C5 Turfgrass Science Division
Summary: The evaluation of a number of green turf colorants revealed that there are a number of parameters that must be considered in order to achieve an aesthetically pleasing turfgrass surface throughout the winter season. Our evaluation concluded that turfgrass managers should focus on a select group of products in order to achieve a quality green color.
Title: Quantitative Trait Loci (QTL) Analysis of Freezing Tolerance in Zoysiagrass
Award and Division: Third place in the Turfgrass Breeders Association - Genetics and Molecular Techniques
Author: H. McCamy Pruitt(1), Jeffrey C Dunne(1), Xingwang Yu(1), Brian M. Schwartz(2),
Aaron J. Patton(3), Consuelo Arellano(4) and Susana R. Milla-Lewis(1) (1)Crop & Soil Science and (4) Statistics, Depts. North Carolina State University, Raleigh, NC (2)Dept. of Crop and Soil Sciences, University of Georgia - Tifton, Tifton, GA (3)Dept. of Horticulture and Landscape Architecture, Purdue University, West Lafayette, IN
Summary:This research is investigating genomic regions associated with winter hardiness in a 'Meyer' x 'Victoria' mapping population that has been evaluated in the field in Laurel Spring, NC and West Lafayette, IN. During this study, a dense DNA marker map of Zoysia japonica was created, and used to identify molecular markers associated with winter hardiness. These markers can be used in the future for development of zoysiagrass cultivars with increased winter hardiness.
Title: Proteomics of Cold Acclimation in Zoysiagrass
Award and Division: Third Place in the Turfgrass Breeders Association - Genetics and Molecular Techniques
Authors: H. McCamy Pruitt(1), Michelle DaCosta(2), Aaron J. Patton(3), Rachael Bernstein(2), Tan D. Tuong(4), Consuelo Arellano(5), David P. Livingston(4) and Susana R. Milla-Lewis(1)(1)Crop Science, North Carolina State University, Raleigh, NC (Stockbridge School of Agriculture, University of Massachusetts-Amherst, Amherst, MA, (3)Agronomy, Purdue University, West Lafayette, IN (4) Plant Science Research, USDA-ARS, Raleigh, NC (5)Statistics, North Carolina State University, Raleigh, NC
Summary:This project focuses on examining protein accumulation changes in zoysiagrass cultivars 'Meyer' and 'Victoria' (Z. japonica) during cold acclimation. Controlled environment freeze tests were used to evaluate freeze response. Protein accumulation in acclimated versus non-acclimated plants was quantified in order to possibly identify the role of certain proteins in increasing freeze response. This could provide a target for selection and ultimately increase our efficiency in breeding zoysiagrass cultivars with improved freeze tolerance.

Title: Adsorption of Chlorantraniliprole: Which Soil Factors Affect Sorbent Affinity?
Division and Award: Second place in the "Soils and Soil Health" division of the undergraduate research poster competition.
Summary: This research was part of a larger project to analyze the movement of chlorantraniliprole, a termiticide, through soil. A batch experiment was conducted which enabled the creation of soil-sorption isotherms and the calculation of Freundlich coefficients for four soils with varying textures and concentrations of OM.
Said Crop and Soil Sciences Department Head Dr. Jeff Mullahey, “Congratulations to all students and to the faculty mentors. Your achievements and success make all of us proud in this department.”
