A researcher at UC Riverside has found a naturally occurring protein molecule that appears to 'cure' huanglongbing (HLB), otherwise known as citrus greening disease, which has devastated Florida's citrus industry and threatens California's.
Here at L.A. Times Plants, we love “plantfluencers” — people whose Instagram feeds and stories are abundantly verdant. We’ve launched a new series, PLANT PPL, where we interview people of color in the plant world, such as the voice behind @LatinxWithPlants, Andi Xoch of Boyle Heights.
After HLB disease appeared in Florida in 2005, it destroyed half the citrus industry’s acreage and production, and pretty much eliminated residential citrus, according to UC Riverside entomologist Elizabeth Grafton-Cardwell, director of the Lindcove Research and Extension Center in Exeter. That’s why California’s $1.
But Grafton-Cardwell said untended residential citrus trees are one of the biggest threats. About 60% of California’s homes have at least one citrus tree, she said , and the industry has been trying to keep people from planting more to reduce the threat to commercial growers.that identifies hot zones of infection. In Southern California they’re mostly where Los Angeles, Orange, Riverside and San Bernardino counties meet. Enter your address to see how close your home is to those infection areas.
If you have an infected tree, Jin said the best approach is to remove it because her antibiotic won’t be available soon. “If you leave a positive tree anywhere, it can serve as a reservoir for psyllid to spread the disease,” she said. “It’s like a malaria-positive person. If one person has malaria in a village, mosquitoes can carry the disease to every other person and infect the entire village. These psyllid can fly pretty far, miles away from an infected tree, so you have to get rid of the source.”
