Information from Dr. Alejandra Jimenez Madrid (Director of the UGA Plant Molecular Diagnostic Laboratory in Tifton):

I am happy to announce that the Plant Molecular Diagnostic Laboratory is currently a USDA-certified lab to perform Huanglongbing (HLB or citrus greening) testing. We are excited to provide this advanced testing to commercial growers, homeowners, nurseries, Extension and research personnel, and the Georgia Department of Agriculture.

Since Candidatus Liberibacter species associated with HLB are regulatory pathogens and subject to PPQ regulatory and permit conditions, we will perform the test according to USDA-APHIS standardized real-time PCR protocols and policies.

Check here for instructions of sample selection, collection, and shipping. Molecular test per sample is $80.00

We look forward to serve our stakeholders in Georgia. If you have any questions, please contact the laboratory director (Dr. Jimenez Madrid) by email ( or phone (229-386-3372).
