Second Case In A Month Of Citrus Greening In California
July 24, 2015 A second case of citrus greening, also known as huanglongbing (HLB), has been detected in at least one more tree following the identification of the second case of disease in a tree in California. The first case was discovered in 2012.
The California Department of Food And Agriculture has expanded the existing HLB quarantine in Hacienda Heights area of Los Angeles County following the detection of the citrus disease.
HLB has been confirmed four times in San Gabriel. First in a kumquat tree on a residential property; second in a lime tree on an adjacent residential property; and finally in calamondin and mandarin trees on residential properties in close proximity to the original find.
The new quarantine will prohibit the movement of all host nursery stock out of the area, while maintaining existing provisions allowing the movement of only commercially cleaned and packed citrus fruit. Any fruit that is not commercially cleaned and packed, including residential citrus, must not be removed from the property on which it is grown, although it may be processed and/or consumed on the premises.
“The success of any quarantine depends on cooperation from those affected, said CDFA Secretary Karen Ross. “The stakes couldn’t be higher for California citrus. We urge residents in the San Gabriel area to do all they can to comply.”
The Asian citrus psyllid, the vector of HLB, was first detected in California in 2008, and quarantines are now in place in 17 California counties.
