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.

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.
