Citrus pest spreads to Jurupa Valley

Issue 16, Volume 16.

JURUPA VALLEY - The Asian citrus psyllid has spread to Riverside County, and state agricultural officials said today they will start spraying small doses of insecticide to try to halt the spread of the insect and the devastating citrus tree disease that it spreads.

State Department of Food and Agriculture officials say emergency action is needed to protect California's $2 billion per year citrus industry from enormous impact should the tree-killing pest spread"citrus greening disease" to commercial groves and backyard trees.

The state found the pest in a trap this month in Jurupa Valley, a semi- rural area northwest of Riverside. That's about 30 miles east of Hacienda Heights, were similar bugs were found March 30 in a lemon tree that had been grafted with an infected pomello grafting.

The pomello branch was likely smuggled into the United States from Asia, agriculture experts have said. That infected tree has been destroyed and other trees are being sprayed from the ground with insecticide to try to retard transmission of the disease Advertisement

by the pest.

State officials have implemented quarantines in Hacienda Heights and Jurupa Valley, where people are instructed not to give away fruit or cuttings.

Agriculture agents will contact homeowners and spray small amounts of an insecticide called cyfluthrin to kill psyllids on contact. A second insecticide, imidacloprid, will be applied to soil beneath trees to control immature psyllids.

Residents of properties scheduled for treatment will be notified at least 48 hours prior to the application.

The pest sucks fluids out of citrus trees and in the process transmits the "citrus greening disease," formally called huanglongbing, It is considered one of the most deadly diseases of citrus in the world.

The California Department of Food and Agriculture scheduled an open house for Wednesday for Jurupa Valley residents to ask questions about the eradication program. It will be from 5:30 to 7 p.m. in the West museum room of the Jurupa Mountains Discovery Center, 7621 Granite Hills Drive.

People who want additional information can call the state's pest hotline at (800) 491-1899.

I don't know, I don't eat them but is an avocado a fruit or veggie? Will this pest effect the avocado groves?

huanglongbing, sounds like some city in Viet Nam.

Wake up California Citrus Growers! As a Florida citrus grower decimated by HLB, I implore that California Growers must take charge; the bureaucrats, regulators, and academics can't solve HLB without your strong oversight! There are already thousands of HLB infected trees in California. They have just not been detected yet. People FedEx in HLB infected Citrus and curry from Asia and plant them in their backyards. This does not matter without the vector. Now that you have the vector, these latent, hidden, infected trees will spread HLB throughout California.  Regulatory exclusion, spraying, and quarantines will totally fail, providing a false sense of security and accomplishment until your doom.  You need to invest serious money into ramping up your scientific research effort to shut down either the bacteria, the vector, or citrus HLB disease expression.  Ultimately if you don't find real solutions via expensive hard science research you will not have a citrus industry. Your current research program is not remotely strong enough on HLB to solve the problem.  As Coach Wooden would say "Be quick, don't hurry!"
