Where can one send plant samples for identification?

The best choice for sending plant samples for identification is the Plant Pest Diagnostics Center at the California Department of Food and Agriculture. This facility is specifically designed for pest and plant disease diagnostics. It has the expertise, tools, and experience necessary to provide accurate identifications and analyses of plant samples. By utilizing specialized knowledge, such facilities can ensure the identification process is thorough and scientifically grounded, which is crucial for addressing any pest issues or plant health concerns effectively.

In contrast, while local universities may have departments that study plant biology or agriculture, they may not universally offer identification services or may not have the specific focus on diagnostics that a dedicated center has. The Environmental Protection Agency generally focuses on regulatory matters and environmental protection rather than direct identification of plant samples. Local agricultural suppliers might have knowledge about regional plants and pests, but they typically lack the comprehensive diagnostic capabilities that a specialized center provides, which makes the Plant Pest Diagnostics Center the most reliable option.
