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!

Weather-Based Tools to Help Delaware Farmers Make Management Decisions
March 25, 2024 | Written by Emmalea Ernest, Phd, Extension Fruit and Vegetable Specialist, Assistant Professor, Department of Plant & Soil SciencesDelaware has a dense network of weather stations that is maintained by Delaware Environmental Observing System (DEOS).

We should let that soak in a little while so we realize the time for spring planting and the insects associated with them is almost here. We will see a variety of springtime insects such as bumble, honey and carpenter bees; also, aphids, caterpillars, and beetles appear in the landscape. In addition to these common insects, we need to watch for some of the exotic invasive insects relatively new to our area – the spotted lanternfly and crape myrtle bark scale. -
