Plant Protection and Quarantine

PPQ protects crops, fields, forests, and other natural plant resources. Among its many services in Indian Country, PPQ can: Provide early detection of potentially damaging foreign weeds, diseases, and insects. Suppress outbreaks of rangeland grasshoppers and Mormon crickets. Combat invasive species that attack forests, such as emerald ash borers and Asian long horned beetles. Train Tribal members to respond rapidly to plant disease and pest outbreaks.

Open to all. 

Plant Protection and Quarantine (PPQ) is responsible for safeguarding and promoting U.S. agricultural health. PPQ is constantly working to defend U.S. agricultural and forest resources from plant pests and diseases. In the face of an increasingly variable climate and more erratic weather conditions, PPQ will continue to play a central role in responding to risk and managing vulnerabilities. In this capacity, PPQ operates on the international and national levels, with regional emphasis as needed, to address and divert plant pest incursions. PPQ is tasked with assessing risk and predicting where an invasive plant pest may be introduced, establish, and spread; these assessments are often based on climatic conditions and host availability. As climate changes, host distribution and landscape conditions deviate from what is considered “normal.” PPQ assessments are based on available data that often reflect past conditions. As climate changes, the actual relevance of these data may lessen our ability to accurately predict and understand risk.
