806 Regulations for Invasive Plants
Summary
Pursuant to the authority granted by Title 3 chapter 29 of the Delaware Code, the Department of Agriculture proposes to amend its regulations.

The Delaware Department of Agriculture is approving these exemptions in order to allow the import, export, purchase, sale, transport, distribution, and/or propagation of these cultivars as they have been conditionally determined as noninvasive as they will not propagate and spread throughout the state. The Delaware Department of Agriculture has presented these exemptions to the Delaware Nursery and Landscapers Association (DNLA) and Delaware Native Species Commission (DNSC). These regulatory amendments with additionally assist the Nursery Industry and small business within the state to increase sales.
The Department of Agriculture is issuing these proposed regulations in accordance with Title 3 of the Delaware Code. This notice is issued pursuant to the requirements of Chapter 101 of Title 29 of the Delaware Code.
