Managing Spotted Lanternflies
This destructive, invasive insect poses a threat to Delaware's agricultural economy.
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 , Master Naturalist , Master Gardeners to 4-H youth clubs and programs that support local agriculture — UD Cooperative Extension has something for everyone!
Make a DIFFerence
Getting involved with UD Cooperative Extension is an excellent way to support and improve your Delaware community. Whether you're volunteering as a 4-H Adult Leader or donating to supporting an Extension Scholar, your local Master Gardener program, UD Cooperative Extension is grateful to have your involvement!

Beauty and Invasion - The Double Edge Sword of Bradford Pears
April 03, 2025 | Written by Sue Barton, Professor - Plant & Soil Sciences, Edited by Michele Walfred and Jackie Czachorowski. Photos by Jackie CzachorowskiWe are on the brink of Callery pear bloom in early April. Our roadsides and abandoned fields have since exploded into a sea of white blossoms.
