Welcome to UD Cooperative Extension


In 1869, the University of Delaware (UD) College of Agriculture and Natural Resources was established as the state’s land-grant university with a mission consisting of three elements: teaching, research and “extension”.

Cooperative Extension fulfills the third part of this mission: bringing knowledge to the people of Delaware. Today, we offer university knowledge, research and resources — just for you! You have questions. We have expert answers.

From nutrition classes and Master Naturalist courses to 4-H youth clubs and programs that support local agriculture — UD Cooperative Extension has something for everyone.

COVID-19: We are facing this challenge together

As the current coronavirus (COVID-19) situation continues to rapidly evolve our goal, as your local Cooperative Extension service, is to assist you in protecting the health and safety of your families, friends and community.
