Due to the state’s response to COVID-19, the staff at the Kansas Department of Agriculture continues to work in a limited capacity with much of the staff working remotely. The KDA headquarters office in Manhattan is now open to the public, with changes to a number of practices in place to protect the health of staff and visitors. 

  • All staff and visitors are required to wear face coverings in public areas of the building.
  • Social distancing must be maintained while in the building.
  • Many meetings are being held as online meetings or conference calls.

We appreciate your patience as we work through these changing times.

The KDA coronavirus page has guidance documents and ag-related industry links. For more information about the State of Kansas response to COVID-19, please consult the KDHE Resource Center.

Plant Protection and Weed Control

Purple and yellow chrysanthemums Plant Protection and Weed Control staff work to ensure the health of  the state’s native and cultivated plants by excluding or controlling  destructive pests, diseases and weeds. Staff examine and analyze pest conditions in crop fields, rangelands, greenhouses and  nurseries. Action taken to control potential infestations of new pests,  whether they are insects, plants diseases or weeds, is beneficial to  the economy and the environment.

 Our mission is to: 

  • Exclude or control harmful insects, plant diseases and weeds;
  • Ensure Kansas plants and plant products entering commerce are free from quarantine pests;
  • Provide customers with inspection and certification services.
