Maintaining high quality plant material involves carefully and routinely observing plants and looking for early signs of infestation or problems with plant material. Correctly diagnosing the problem is also key to an TPM/IPM plant management approach. Commercial plant samples suspected of having disease problems can be sent to the Plant Diagnostic Lab.

This Web Site is designed to help commercial horticulturists and IPM scouts involved with nursery, greenhouse and landscape management to correctly identify and address problems with diseases, insects, mites, and fertility management. The website is a cooperative effort among regional specialists and extension educators, and it is maintained through the Central Maryland Research and Education Center.

Information for  homeowners is available at the Home and Garden Information Center website or call within Maryland on their toll free number at 800-342-2507 (weekdays 8 a.m. to 1 p.m.).
