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!

    From the development of rudimentary tools to today’s cutting-edge machinery, technological innovation in agriculture has steadily improved the efficiency of food and livestock production. Tools such as reapers, sickles, animal-drawn plows, seed drills, threshing machines, and a host of others from the early ages helped transform farming practices, with newer technology evolving from earlier ones or ideas. Even though tractors have come to symbolize mechanized agriculture, more advanced equipment, such as combines, has been part of the agricultural landscape over the past two centuries, further pushing the frontiers of what is possible on the farm.
