Disease Pest Identification
Identifying plant disease in the garden, lawn, and landscape begins by investigating the host plant and looking for clues. The following resources provide information, many through pictures, that aid in identifying the disease pest.
Garden
Lawn
- Plant Disease Diagnostics - Turf (Yard and Garden Line, University of Minnesota Extension)
- Turfgrass Diseases in Georgia: Identification and Control (University of Georgia Cooperative Extension)
Landscape
Image Resources
Pictures can be an important tool in helping you diagnose problems in the landscape.
- Oregon State University Image Index (Oregon State University Extension) provides a searchable index of plant disease images
- Integrated Pest Management Images (ipmimages.org[1]) offers an extensive collection of images on many topic, including diseases, insects, and other pests
- Invasive Diseases (www.invasive.org[2]) documents many of the most troublesome diseases that originated in other parts of the world
Local Diagnostic Laboratories
If you cannot identify your disease problem with the resources provided, you may be able to submit information to your state diagnostic plant laboratory using:
- University Plant Diagnostic Clinic Web Addresses (Maintained by the American Phytopathological Society)
Fungicide Use and Products
While plant diseases may be caused by a number of organisms, such as bacteria, fungi, viruses, or phytoplasmas, only fungal plant diseases can be effectively controlled through the use of chemical pesticides. A fungal pesticide is called a fungicide. Fungicides and their use vary by state.
Fungicides for Disease Control
- Oregon State University Extension: Fungicides for Disease Control in the Home Landscape (Oregon State University Extension) is an up-to-date article on fungicide use; explains the categories of fungicides generally available to the home gardener, including major common names, notes on uses, and cautions (Most of the information is broadly applicable but some is specific to the Pacific Northwest)
Fungicide Chemical Information
The fungicide label is a legal document that provides instructions for proper fungicide usage. All pesticide containers are required by law to have a pesticide label. Another important document, the material safety data sheet (MSDS), informs the user about the chemical's physical properties and safe work practices. Label and MSDS information can also be found by using the Web sites listed below. Some of these sites may require you to register free of charge before using.
- Home Use Pesticide Database (Colorado State Extension)
- Pesticide Information (Center for Urban Ecology and Sustainability, University of Minnesota)
- CDMS Agro-chemical Database (Crop Data Management Systems Inc.)
- Greenbook.net (Greenbook, Vance Publishing Corporation) - use the search feature to find labels and material data safety sheets for insecticides
Find State Regulatory Data for your state:
- KRSNetwork (Kelly Registration Systems Inc.)
- -User hint: Under the "Our Services" tab, scroll down to find the Information Resources, then State Regulatory Data section, and select a state from the drop-down menu.
