California's citrus plants could be in trouble if a disease known as "citrus greening" spreads.

In the face of a huanglongbing outbreak, growers are being required to monitor groves for pests, even if they've abandoned them because of the high cost of irrigation, say agricultural officials.

Farmers in Northern San Diego County have reportedly been shutting down orchards in the Valley Center area because of rising water costs. Some trees, however, have survived on rainfall, and officials do not want them to become pest infested.

Sometimes called "citrus greening," huanglongbing disease -- an incurable citrus massacring contagion spread via the Asian Citrus Psyllid-- was discovered last week in Hacienda Heights prompting 93-square mile quarantine in Los Angeles and Orange counties.

The county's agriculture department is preparing a letter to growers reminding them of their responsibility, reports the North County Times. The outbreak threatens to decimate the state's $2 billion citrus industry.

93-square-miles of Los Angeles County is under citrus quarantine, state agricultural officials announced late Tuesday night.

The quarantine prohibits removing any citrus fruit from the area that is not commercially cleaned and packed. No fruit may be removed from property on which it is grown (although it may be consumed onsite).

The deadly citrus disease, huanglongbing (also know as "citrus greening"), has had bug detectives itching for months in anticipation of the seemingly imminent infestation. Recent discoveries in the the Hacienda Heights area had CA officials walking door-to-door collecting samples from backyards just days ago.

The quarantine area -- centered near State Route 60 -- extends south into Orange County, north into Baldwin Park and West Covina, west into South El Monte and Whittier and east into Walnut and Rowland Heights, said the California Department of Food and Agriculture said in a statement.
