USDA PPRL

Functionality & Mechanism

Developed by the USDA Poisonous Plant Research Laboratory (PPRL), this application functions as a mobile reference guide. It leverages content from Agriculture Information Bulletin No. 415, enabling users to search for detailed information on poisonous plants and their associated livestock poisoning symptoms. The interface is structured for rapid plant identification based on visual and textual data. A dedicated module also facilitates the direct submission of suspected livestock poisoning reports to the PPRL for expert review and data collection.

Evidence & Research Context

• The application's core content is derived from Agriculture Information Bulletin No. 415, which synthesizes federal research on over 30 principal poisonous plants affecting western rangelands.
• The associated research documents that poisonous plants adversely affect 3% to 5% of cattle, sheep, and horses grazing these ranges, causing significant economic losses.
• The app is developed and maintained by the USDA-ARS Poisonous Plant Research Laboratory, a federal institution with a mission to identify plant toxins and develop management strategies.
• The laboratory's interdisciplinary research provides the scientific foundation for the information delivered through the application, supporting veterinarians, producers, and land managers.

Intended Use & Scope

This tool is designed for livestock producers, ranchers, and agricultural professionals as a preliminary field reference for plant identification and risk assessment. Its primary utility is to augment awareness and support initial decision-making. The application is not a substitute for formal veterinary diagnosis, toxicological analysis, or definitive botanical identification of plant species. Professional consultation is required for animal treatment.
