SAN DIEGO — A potentially threatening citrus tree disease was detected in Rancho Bernardo this week, said the County of San Diego Communications Office.
The bacterial disease, known as Huanglongbing (HLB), is a threat to San Diego’s annual citrus crop, which the county says is worth around $115 million. The disease is spread by tiny insects that feed on citrus trees. Urban farming: Why San Diegans should raise chickens at home
In response to the disease, which was found in a residential lime tree, the California Department of Food and Agriculture has declared a new citrus quarantine in a 95 square-mile area. This is in addition to a quarantine that was already in place for the City of Oceanside, the county said.

The county said the quarantine order is meant to protect the region’s food supply and support the agricultural economy, along environmental sustainability.
“Unfortunately, Huanglongbing is fatal to citrus,” said San Diego Agricultural Commissioner Ha Dang. “Our goal is to prevent this disease from spreading any further. By working together, we can all protect our food supply, local agriculture, and environment from this devastating disease.”
Plant quarantine explained
What exactly is a citrus quarantine? To reduce the spread of HLB, residents and business owners are restricted from moving citrus nursery stock, plant parts and fruit outside the quarantine boundaries or off their properties.
The only exception, according to the county, is for agricultural businesses that must follow specific requirements for treatment, cleaning and packing commercial fruit before moving it. California trees are dying by the tens of millions

— Consider removing your citrus tree if you no longer need it.
