Dr. Marisol Quintanilla is an Applied Nematologist at Michigan State University.   Marisol grew up in a family farm in Chile that produces table grapes and diverse other crops.  Marisol received her master’s and doctoral degrees at MSU with nematologist Dr. George Bird. After leaving MSU, she spent two years at Northern Marianas College and then moved to the University of Hawaii.  Her work included nematode identification and analysis of trials with Dr. Koon-Hui Wang and gained extensive experience in working with specialty crop growers. Most recently, she has studied nematode community structure, soil health and pest management in edible crops as part of her research and extension work.

Marisol collaborates with faculty in finding applied solutions to plant parasitic nematode problems in the state’s key crops. Nematodes are microscopic and worm-like. While some are beneficial, others are plant parasites and are causing significant losses for Michigan’s field, vegetable, fruit and ornamental crops. The developed management practices aim to increase soil health and beneficial organism populations. Additionally, Quintanilla will research biorational and conventional products for nematode control and possibly test resistant varieties. She shares the research-based results with growers and agricultural professionals through multiple extension methods.

Program Description


Marisol’s research interest will be finding applied solutions to plant parasitic nematodes in Michigan’s field, vegetable, fruit, and ornamental crops.  Existing and potential nematode control products and strategies will be tested, and their effect on soil health will also be considered. 


Nematode research produced by faculty will be communicated to farmers and agricultural professionals. Knowledge gained regarding sustainable management practices evaluated by our research efforts in cooperation with department faculty and statewide team will be passed on to the growers.

Dissemination of research information regarding nematode exclusion, sustainable management, control, and host resistance will be done through extension meetings, personal farm visits, talks, videos, website, extension publications, and scholarly publications.  Nematode education programs will be organized in collaboration with other faculty and extension agents.
