What is the concern?
- The disease will kill trees in as little as five years.
- There is no cure or effective control method for HLB.
- Reducing the psyllid population helps to slow the spread of the disease.
Inspect your citrus trees for psyllids.
- From spring through fall, look for psyllid eggs, nymphs, and adults on new leaves.
- Adults are about the size of an aphid. The feed with their heads down and their “tails”
in the air.
- Nymphs are tiny and yellowish and they excrete white waxy tubules.
What are the symptoms of HLB disease?
- Leaves show yellow mottling with patches of green.
- Fruit is small, lopsided, and falls off the tree easily, while the juice is bitter.
What should you do if you think you have the Asian citrus psyllid or HLB?
- Put a sample in a locking bag and bring it to your local UC Master Gardener office or your local Agricultural Commissioner office.
- DO NOT move plants or clippings out of psyllid-infested areas, because they can spread the insect and disease.
