Weeds Research Programs


Approximately 22 million acres of crops are harvested each year in Kansas. Essentially all require some form of weed management for reliable, economic crop production. In addition, weed control measures are needed on the 20 million acres used for grazing each year.

Weed Research 

Research Objectives

The overall objective of the Weed Science program is to develop new technologies and integrate weed management strategies to enhance sustainable farming and ranching systems. Investigations consist of basic research to increase knowledge and understanding of weeds, agronomic crops, their interactions, and ramifications of new technologies; and applied research to develop, evaluate, and/or refine new methods and technology, including testing and developing experimental herbicides, and the integration of multiple weed management strategies to improve weed control and reduce crop and environmental risks.

Contributions from basic research have national and international application, while contributions from applied research are applicable throughout major portions of the Midwest, Great Plains, Intermountain region, and western U.S. Extension and technology transfer to provide unbiased evaluations of herbicide products and cultural/biological control methods are vital since 75% of the pesticides used in Kansas are herbicides.
