U.S.: Citrus greening detected in San Bernardino County

Regions in California have quarantined the citrus greening disease was found on a single citrus tree in San Bernardino County.

This led to an expansion of already quarantined areas of citrus in the state.

The CDFA said in a statement that the quarantine area spans 93 miles and will link up with existing quarantines in Los Angeles and Orange Counties. In total, the citrus trees quarantined represent a 1,015 square-mile area.

Along with revealing suggestions for tree owners, CDFA staff announced it will remove infected trees and is currently coming up with a treatment program.

As the disease is spread by the Asian citrus psyllid, the project is also concerned with "knocking out" the insect infestations.

The governmental bodies detailed that the movement of citrus nursery stock or plant out of the quarantined area is prohibited. This applies to fruits such as oranges, lemons, grapefruits and kumquats. Further, orchards have provisional stock of fruit that will allow the movement of commercially cleaned and packed citrus fruit.

CDFA also stated that fruit that is not commercially cleaned and packed will not be moved from the property on which it is grown.

Also known as Huanglongbing (HLB), greening is a bacterial disease that impacts the vascular system of citrus trees and plants.

It is spread by the Asian citrus psyllid and there is no cure once the tree is infected. The resulting fruit of an infected plant is bitter and misshaped. After a few years with the disease, the tree will die.

Also called citrus greening disease, it has never been detected in the county before. California's agriculture authority - CDFA-  is working with the U.S. Department of Agriculture (USDA) and local agricultural groups in the quarantine project.
