Citrus greening in leaves
Asymmetrical yellowing on citrus leaves can be symptomatic of citrus greening, or Huanglongbing. This kind of yellowing is different from the symmetrical yellowing that can be indicative of nutrient deficiencies in the tree.

New state rules allow citrus shipments from quarantine zones

Bulk citrus shipments allowed from Huanglongbing quarantine zones, with specific conditions

California regulators will now allow bulk citrus grown in a Huanglongbing quarantine area to be shipped for final packing outside of that original zone.

To do this, all growers, packers and transporters must operate under a signed compliance agreement with the Asian citrus psyllid/HLB program.

Growers in an HLB quarantine who send fruit for packing outside the original quarantine must meet the following requirements:

  • Fruit must be processed through a wet wash, which includes thoroughly wetting the fruit by spraying, dunking and drenching with water, and brushing and cleaning.

If this is not done, both of the following must be completed before fruit can be moved:

  • Groves must be treated with a state-approved pre-harvest product effective against psyllids within 14 days of treatment, and,
  • Fruit must be field-cleaned and free from all stems, leaves and other extraneous host material prior to leaving the grove of origin.

Packers and processors outside an HLB quarantine that receive citrus grown within a quarantine zone “shall give priority” to such shipments for receiving, unloading and cleaning.

The pest exclusion advisory related to these restrictions is available online.

Questions about this can be directed to Anmol Joshi, southern California quarantine supervisor with the CDFA at [email protected].
