North Dakota State University Department of Plant Sciences head, Dr. Richard Horsley, recently announced the retirement of Extension weed specialist, Dr. Rich Zollinger.

Zollinger has worked almost 28 years as a professor and Extension specialist in weed control. During his tenure, he received numerous awards and was active in many professional organizations. He published more than 200 reports of his research, averaged over 100 presentations annually at stakeholder meetings and scientific conferences, and mentored and advised numerous NDSU graduate students.

Dr. Horsley’s full announcement is below.

Dr. Rich Zollinger announced his retirement from the North Dakota State University Extension Service and the faculty of the Department of Plant Sciences, effective December 31, 2017. At that time, Rich had completed almost 28 years as the NDSU Extension Weed Specialist. Rich joined the Department of Plant Sciences in 1990 as an Assistant Professor with responsibilities in Extension weed science, weed control and herbicide research. He earned his Ph.D. in Weed Science from Michigan State University in 1988; and his M.S. and B.S. degrees from Utah State University in 1985 and 1983, respectively. Rich was raised on a family farming operation with livestock and crop production farms in Utah, Idaho, Montana, and an 18,000-acre farm in the Peace River Region of British Columbia, Canada.

As the NDSU Extension weed specialist, Rich’s statewide educational efforts covered most crops except sugarbeet and potato. Every year, Rich would oversee the updating and compiling of the North Dakota Weed Control Guide (W-253). Over 20,000 copies of this publication are printed each year and it is considered by many as the flagship publication of the NDSU Extension Service. Dr. Zollinger conducted weed control and herbicide research primarily in corn, soybean, dry edible beans, and sunflower. His main research interest was in adjuvants and formulations. His weed science project conducted over 70 field trials each year in these areas. In addition, the project also had a dynamic greenhouse testing program which allowed them to adapt to many different testing objectives. Rich was successful in writing over 140 Section 18 herbicide registrations in minor acreage crops, serving as the IR-4 liaison for North Dakota and successfully competing with California and ‘rim’ states for over 100 IR-4 pesticide research projects.

Rich was active in publishing the results of his Extension and research activities in over 200 publications distributed by the American Society of Agronomy, American Society of Testing Materials (ASTM), North Central Weed Science Society, the NDSU Experiment Station, the NDSU Extension Service, Weed Science Society of America, and the Western Society of Weed Science. Additionally, Rich averaged over 100 presentations annually at stakeholder meetings and scientific conferences. Rich mentored and advised numerous graduate students that earned their degrees at NDSU.

Rich won numerous awards and recognitions during his tenure at NDSU, including Weed Science Society Fellow in 2017, ASTM – E35 Committee on Pesticides and Adjuvants Outstanding Service Award in 2010, inducted into the Gamma Sigma Delta national honor society for agriculture in 2009, North Central Weed Science Society Distinguished Extension award in 2006, NDSU College of Agriculture Excellence in Extension Award – Senior Career in 2004, American Society of Agronomy Excellence in Educational Materials Award in 2003, IR-4 SAES/ARS Meritorious Service Award in 2002, and the Weed Science Society of America Outstanding Extension award in 2001.

Rich is active in several professional organizations such as Agricultural Consultants Association of North Dakota/Advance Crop Advisor Association, ASTM, Council for Agriculture Science and Technology (CAST), Epsilon Sigma Phi (ESP) –the honor society of Extension, Gamma Sigma Delta (GSD) – the honor society of agriculture, IR-4 – SAES/ARS, the International Society of Adjuvants for Agrochemicals (ISAA), National Sunflower Association, North Central Weed Science Society, Weed Science Society of America, and the Western Society of Weed Science.

After a very rewarding, challenging, demanding and fulfilling career, please join me in wishing Dr. Rich Zollinger a long and enjoyable retirement!
