Mature citrus trees affected by the bacterial disease huanglongbing (HLB) typically need about 25 percent less irrigation than their healthy counterparts However, that doesn’t necessarily mean young trees with the disease will benefit from water deficits, according to a preliminary greenhouse study by researchers with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Experiments on 1-year-old orange … Read More
Citrus Tree Covers Keep Deadly Psyllids Away
University of Florida (UF) scientists are finding that by covering new citrus trees with mesh, they can keep disease-carrying insects from harming the plants. That could be a big step toward stemming the deadly citrus greening disease, UF Institute of Food and Agricultural Sciences (IFAS) researchers say. Asian citrus psyllids can infect the citrus trees with greening, also known as … Read More
Control of Citrus Flush Timing Could Improve Psyllid Control
They say timing is everything in life, and that’s certainly true of the Asian citrus psyllid, which has devastated Florida agriculture for the past decade by transmitting citrus greening disease, also known as huanglongbing or HLB. To reproduce, this small, flying insect must lay eggs on citrus “flush” – the tender new leaves and shoots that citrus trees produce several … Read More
New Florida Citrus Production Guide Debuts at Citrus Expo
Beginning this week, Florida citrus growers will have an updated resource to help them keep groves productive despite the ever-present threat of huanglongbing, the bacterial malady also known as HLB or citrus greening disease. Experts with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) have just completed a 180-page technical handbook, “Florida Citrus Production Guide 2018-2019.” It … Read More
Single Breakthrough Discovery for HLB in Florida Unlikely
A single breakthrough discovery for managing citrus greening in Florida in the future is unlikely, says a new report by the National Academies of Sciences, Engineering, and Medicine. The committee that wrote the report called for a systems approach to prioritize research on the disease and strategically distribute resources for research to effectively manage the disease, which is the most … Read More
Research Reveals a New Direction for Halting HLB
New clues to how the bacteria associated with citrus greening infects the only insect that carries it could lead to a way to block the microbes’ spread from tree to tree, according to a study in Infection and Immunity by Agricultural Research Service (ARS) and Boyce Thompson Institute (BTI) scientists. Citrus greening, also known as huanglongbing (HLB), is a serious disease dramatically … Read More
OJ May Soon Come from HLB-Tolerant Fruit
Some people like to wake up and drink a glass of fresh Florida orange juice. With the greening disease ravaging Florida’s citrus industry, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers want to make orange juice from disease-tolerant fruit. Huanglongbing (HLB), or citrus greening as it’s commonly called, has destroyed 80 percent of citrus in Florida, a … Read More
