Dr. Shunping Ding is an assistant professor in the Wine and Viticulture and Horticulture and Crop Science departments at California Polytechnic State University in San Luis Obispo. She is a microbiologist and plant pathologist who studies grapevine diseases and plant disease management on the Central Coast.
Dr. Ding is a researcher in plant disease diagnosis, plant pathology, and the detection of fungicide resistance in pathogens. She gained interest in pursuing plant pathology as a child due to her plant ecologist father's work in the forest in China. She has a B.S. in Biological Sciences from Henan University, China, a Master of Philosophy in Microbiology from The University of Hong Kong, and a Ph.D. in Plant Pathology from the University of Wisconsin-Madison. She has four published research papers in peer-reviewed publications. Through her three main research projects, she emphasizes and supports the ultimate practices of sustainable agriculture.
Sustainable agriculture includes a system that is environmentally sound, economically viable, and socially just.
Dr. Ding's first research project is identifying and treating a deadly complex called Trunk Disease. There are a number of pathogens identified so far, such as pathogens in the genera of Eutypa, Botryosphaeria, and Diplodia. This disease causes the vines to decline in production and threatens the longevity of the vineyard. It is very hard to identify and growers generally do not know which pathogen causes the disease. Dr. Ding's research is on finding the pathogen responsible for this disease and trying to figure out which ones are more prevalent in the Central Coast.
Another study that Dr. Ding is working on is the study of how fungicides can lose their efficacy over pathogens. She says that "over time in the population, the resistance portion is becoming dominant, and that's when the fungicide will lose its efficacy". To study this area of resistance, Dr. Ding collects Powdery Mildew pathogens from all over the Central Coast to see if the pathogen population carries the mutation that confer the fungicide resistance. Then, she will give the information to the growers to assist them in better fungicide selections.
Dr. Ding's main key message to the public is the importance of sustainable agriculture. She is passionate about making sure growers and winemakers know the impact of managing and mitigating fungicide resistance. She stated that "It’s also important to know what fungicide your pathogens are resistant to so you don’t overspray and waste resources." Dr. Ding is considerate of growers economic stability, as well as passionate about maintaining a sustainable practice of agriculture.
Dr. Ding's future plans include a few projects. Dr. Ding and her students will be working on Botrytis bunch rot and management and will again be a mentor for the summer research program that occurs every summer at Cal Poly. Dr. Ding continues to be excited for not only her research, but the possibility of sharing it with the scientific and agricultural community.
