How to Manage PestsAbout Pest Management Guidelines and Other Identification Databases
The UC Statewide IPM Program developed the Pest Management Guidelines, Pest Notes, Natural Enemies Gallery, and Weed Photo Gallery to provide practical information on pest management techniques and identification for a broad range of California pests. Management suggestions apply to California, but also may be useful in other areas. This information is frequently modified and expanded to reflect recent changes in pest management techniques, pesticide registrations, and pest status. The primary sources of information for all three databases are scientists at the University of California's Division of Agriculture and Natural Resources (ANR). These databases are maintained by the Statewide IPM Program. Pest Management Guidelines and Pest NotesThese databases are authored primarily by University of California scientists. Authors are noted on each document. Before publication, each manuscript goes through an ANR peer-review process and receives a ANR publication number. Once published, each document is reviewed periodically—at least every three years—but usually more often. For Pest Management Guidelines, "updated" and "reviewed" dates appear beneath the name of each pest. Reviewed indicates when the guideline was last reviewed for completeness and current information. Updated indicates when the document was last changed. Often a review will reveal no need for changes so the review date may be more recent than the update date. Occasionally (especially when pesticide registrations change), a guideline will be updated to reflect a minor change, but the entire guideline will not be reviewed. PesticidesPlease note that the pesticides listed in Pest Management Guidelines and Pest Notes conformed to the registered California pesticide labels at the time the guidelines were written and entered or last reviewed. Pesticide registrations change frequently at both the state and federal levels, and IPM staff update the databases when notified. Ultimately, users are responsible for ensuring that their usage conforms to current labels and local regulations. This system is not an index of state or federal pesticide registrations. It lists only those pesticides specifically suggested by the authors as being effective against the pest and compatible with the goals of the pest management program. It does not provide labels, complete label directions, or complete label information. Before each pesticide application, make sure you have a current pesticide label and be sure to follow its instructions. Check with your county agricultural commissioner for the latest restricted interval requirements. To simplify information, trade names of products (and, in some cases, specific formulations) may be used. No endorsements of named products are intended, nor is criticism implied of similar products that are not mentioned. Natural Enemies GalleryThe Natural Enemies Gallery includes photographs and descriptions of natural enemy species commonly found on California farms and in landscapes. Natural enemies are organisms that kill, decrease the reproductive potential or otherwise reduce the numbers of another organism. They include predators, parasites, and pathogens. In the gallery, they are identified by order and family, and common and scientific names. The information was compiled largely from the Natural Enemies Handbook: The Illustrated Guide to Biological Pest Control. Weed Photo GalleryThe Weed Photo Gallery includes photographs and brief descriptions of more than 125 weed species in the Pest Management Guidelines. The weeds are identified by their common, scientific, and family names. In addition, each agricultural crop has an individual weed gallery, as does the guideline for turfgrass. Members of the UC Davis Weed Group, including Joseph DiTomaso, Clyde Elmore, Thomas Lanini, and Robert Norris, along with UC IPM Advisor Cheryl Wilen, reviewed each weed species collage. DiTomaso also provided guidance on the usage of the common, scientific, and family names.
