This week the USDA has launched a new effort to raise awareness of the threat posed by citrus greening disease in California. 
Californians in Los Angeles and Orange counties will soon see mobile advertisements in English and Spanish proclaiming “Don’t Go Green!” because “Greening Disease (HLB) Kills Citrus.”
Citrus tree owners are encouraged to “Learn, Check, Report” suspected citrus diseases. Residential growers can learn about the diseases on the Save Our Citrus website. They should check citrus plants regularly for signs of disease. And they can report suspicious symptoms through the website or by using the free Save Our Citrus iPhone App available for download from the iTunes store. Residents can also call the California Department of Food and Agriculture hotline 800-491-1899.
