The CREI laboratory focuses on conducting a wide range of tests for citrus diseases that if allowed to spread would have a devastating impact throughout the industry. These laboratory tests are done to support three programmes that CREI implements:
- Belize Citrus nursery Certification Programme (BCCP) - testing nursery budwood and seed source trees for the presence of citrus tristeza virus, exocortis viroids, Ttatterleaf, blight, cachexia, and psorosis.
- Programme to control the spread of HLB-greening disease.
- Surveillance for exotic diseases - citrus leprosis virus, citrus canker, citrus variegated chlorosis - that is conducted three times each year.
