The mission of the Delaware Department of Agriculture is to sustain and promote the viability of food, fiber, and agricultural industries in Delaware through quality services that protect and enhance the environment, health and welfare of the general public. The agency includes the following sections:

Food Products Inspection plays a vital role for agriculture in support of the animal and vegetable segments of our state's agricultural economy.

The Forest Service also offers Smokey Bear, Project Learning Tree and other education programs. Professional foresters provide financial and technical assistance to communities for urban forestry projects. In addition, foresters diagnose forest pest problems and recommend treatments; develop woodland management programs; conduct forest inventories and inspections; provide information on selecting timber buyers; supervise harvesting, reforestation, and timber stand improvement activities; and assist with wildfire suppression and training programs.
