Plant disease testing saves New Mexico growers money
Plant diseases threaten crop yields, farm profitability and export markets. Most New Mexico farms are small or family-owned and lack access to private diagnostic services, increasing vulnerability to disease outbreaks and unnecessary pesticide use.
The New Mexico State University Plant Diagnostic Clinic provides New Mexico farmers with free diagnostic services using culture-based and molecular testing to identify plant diseases and recommend integrated pest management strategies. The clinic expanded testing capacity and outreach to meet increasing regulatory and industry needs.
In 2025, the clinic processed over 1,200 samples—an increase of nearly 30%. Free diagnostic services through Extension saved producers an estimated $36,000 in testing fees while supporting biosecurity, export compliance and improved disease management. Over 90% of program participants reported improved disease management knowledge.
Accurate and timely plant diagnostics protect New Mexico’s $4 billion agricultural economy by preventing disease spread, reducing unnecessary chemical use and supporting export compliance.
