Mark J. VanGessel
- Ph.D., Weed Science, Crop Science Department, North Carolina State University. Spring 1992.
- M.Sc., Weed Science, Crop and Soil Sciences Department, Michigan State University. Spring 1989.
- B.A., Political Science, Hope College, Holland, MI. Spring 1982.
- My extension program focuses on developing and disseminating weed control recommendations and other technical information appropriate to agronomic and commercial vegetable crops. Technical information emphasizes weed biology and ecology. Extension responsibilities include weed management for agronomic crops in New Jersey.
- Research efforts fall into five main areas: weed biology and ecology, integrated pest management, perennial weed management, herbicide-resistant weeds, and herbicide evaluation. Research has focused on agronomic and commercial vegetable crops important to the mid-Atlantic region.
