Based on the lessons learned by the Florida-HLB experience, Brlansky offered these suggestions for citrus growers in California, Texas, and Arizona (when the disease is not widespread).

Keep the pathogen out. Regulate propagating materials to prevent introduction.

  • Eradication if found early. Use good available detection systems.
  • Reduce the psyllid populations; this is a big challenge.
  • Manage the grove as if HLB is already present.
  • Always use disease-free nursery stock.
  • If HLB is found, remove the infected tree and treat the stump to prevent sprouts.
  • If HLB is present, remove alternative host plants, including orange jasmine (Murraya paniculata) and box orange (Severinia buxifolia).
