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!

UD Extension had a busy (and unprecedented) year yet again in 2021. Check out our 2021 Year in Review recap slideshow to see just some of this excellent work!

Managing Spotted Lanternflies
 

This destructive, invasive insect poses a threat to Delaware's agricultural economy. This winter and spring, it is important to watch for and destroy their eggs by scraping them into a plastic bag with rubbing alcohol.
