Sample Submission


Sample submissions from commercial and backyard growers are free for a limited time.
This program is funded through a competitive grant from the National Institute of Food and Agriculture–Agriculture and Food Research Initiative for Global Food Security, awarded to researchers at the UH College of Tropical Agriculture and Human Resources, in collaboration with Agricultural Diagnostic Service Center.

When do I collect my samples?
Collect FRESH samples late on a Monday or early Tuesday morning for drop-off by 9:00 A.M. on Tuesday.

What do I need for sample collection?
  • Download the HLB sample submission form at and complete for each sample. Provide detailed sample location so the plant can be located again. GPS coordinates are preferred, but not mandatory. Forms are also available at  CES offices.
  • You will also need pruning shears, zip-lock bags, and cool blocks or ice. KEEP YOUR SAMPLES COOL and out of the sun, but DO NOT freeze. Cool blocks will be returned.

What plant parts do I collect?
  • Collect 3-4 stems with 5-8 symptomatic leaves attached to each stem. If including fruit, leave attached to the stem.
  • Place sample in a zip-lock bag and seal. Place sample in a second zip-lock bag, insert folded sample submission form between  inner and outer bag and seal. Repeat for each sample. 
  • Pruning shears can be dipped in 10% bleach for 2-5 minutes, rinsed in water, and dried, between samples. Spread by shears has not been reported.
