This page is devoted to information for identifying and managing weed pests.
A more focused reference for nursery production in the Northwest is the website developed by Dr. James Altland, formerly OSU Nursery Extension (now USDA-ARS). While some information is dated, this site still has lots of good information and wonderful images.
Weed Management in Nursery Crops
Another container weed reference site is Weeds of Container Nurseries in the United States by Joseph C. Neal, North Carolina State University and Jeffrey F. Derr, Virginia Tec.
The UC IPM website has a herbicide damage to ornamentals photo database.
Interested in herbicide resistance? You might find the following site useful: International Survey of Herbicide Resistant Weeds.
Particularly useful is the list of resistant weeds by state.
