Citrus tree disease expands in LA and Orange counties
Topline:
Sweet orange scab, a plant disease that can harm citrus trees, continues to expand in our region. The California Department of Food and Agriculture recently expanded a quarantine in parts of L.A. and Orange counties.
What is it? SOS is a fungal pathogen that causes young citrus fruit to look scarred. The disease can lead to premature fruit drop and stunt the growth of young trees. Tangerines, sweet oranges and other citrus are at risk.
Where is it? After it was previously found in L.A. and Ventura counties last year, sweet orange scab has expanded into both the Irvine and La Puente areas. Officials expanded the quarantine zone to include those areas, which means residents should not move plants.
You can visit the CDFA’s website to see a map of currently quarantined areas.
What if your tree has it? There isn’t currently a treatment for SOS, but you don’t have to pull your tree out and can still eat the fruit. You can call the CDFA’s pest hotline at (800) 491-1899 to report any trees you suspect have the disease.
Why it matters: The CDFA said quarantine areas have expanded to try to keep the disease away from commercial growers. SOS can cause blemishes, lesions and other symptoms on citrus fruit, and no one wants to buy scabbed fruit.
