Current Insect and Disease Quarantines in Santa Clara County
Asian Citrus Psyllid
Quarantine on citrus fruits, leaves, and trees; also Indian curry leaf, an alternative host
Indian curry leaf (Murraya koenigii) can also host this insect, so falls under the quarantine as well.
This Citrus Research Board presentation explains the relationship between the Asian Citrus Psyllid (ACP) and the HLB disease, how to recognize the different stages of the ACP insect, how the HLB disease affects citrus, and the many ways that the insect can accidentally be transported into California. See also the UC IPM Pest Note on the Asian Citrus Psyllid.
Much of California, including Santa Clara County, is under quarantine for the ACP insect (CDFA quarantine map). As yet, there are no local areas under quarantine for the HLB disease. (An HLB quarantine is in effect in parts of Southern California.)
What the quarantine means
Clean fruits can be moved out of the quarantine zone
Homegrown citrus fruit that is clean of all stem and leaf material can be moved out of the quarantine area. Washing the fruit is a good extra precaution to take.
Plants and fruit can be moved within the quarantine zone
Plant material (whole plants, leaves) from backyard citrus or curry leaf plants may be transported within the quarantine area.
Plants can NOT be moved out of the quarantine zone
Plant material other than fruit (whole plants, leaves) from backyard citrus or curry leaf plants can NOT be transported out of the area. However, it CAN be put into local green waste collection.
