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 …
By Len Wilcox University of California Davis (UC Davis) researchers have identified the sex pheromone of the Asian citrus psyllid (ACP), a discovery which will lead to better methods of controlling the pest. The ACP is a major threat to citrus around the world. The psyllid is a tiny insect with the potential to wreak havoc as it spreads the …
Huanglongbing (HLB), or citrus greening disease, was a hot topic at the recent Georgia Citrus Association Conference held in Tifton. As the Georgia citrus industry continues to grow, it is taking precautions to prevent the spread of HLB. Lindy Savelle, president of the Georgia Citrus Association, said although HLB has not been detected yet in Georgia, the industry is preparing …
By Rhuanito S. Ferrarezi, Alan L. Wright, Kelly T. Morgan, Philip A. Stansly, Monica Ozores-Hampton and Robert Ebel Huanglongbing (HLB) or citrus greening is endemic in Florida, resulting in billions of dollars of losses since the state’s first detection in 2005. The disease induces visual symptoms in leaves and branches, while severely impacting citrus fruit yield and quality. Fibrous root …
Although the Florida and California citrus industries may differ, they are both vulnerable to citrus greening disease. The brightest minds from both states are working to detect, manage and control this devastating disease. Most recently, University of California researchers have been working to find methods for early detection of huanglongbing (HLB), or citrus greening disease. AgNet West’s Taylor Hillman has …
The sixth International Research Conference on Huanglongbing (IRCHLB VI) will be held in California. The conference has been scheduled for March 12-16, 2019, at the Riverside Convention Center in Riverside. This is the first time the conference will be held in California. Sponsored by the California Citrus Research Board (CRB) with the support of California’s citrus industry partners, the gathering …
By Len Wilcox Early detection of citrus trees infected with huanglongbing (HLB) has become the target of researchers around the world, and scientists from the University of California (UC) now believe they have the answer. Early detection is vital for identifying HLB-positive trees before physical symptoms of the disease appear and it spreads throughout a grove. SMELLING THE SICKNESS UC …
By Megan M. Dewdney, Tripti Vashisth and Ariel Singerman In 2017, the damage from postbloom fruit drop (PFD) was lower than the previous three years. This was mainly due to the low rainfall accumulation in late winter and early spring. The long bloom with relatively few flowers at any one time made the decision of when to apply a fungicide …
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 …
After 100 years of assertions about the roots of citrus, a global group of scientists — including a University of Florida professor — has traced the evolutionary history of Florida’s signature crop up to 8 million years ago in the Himalayas of Southeast Asia. Through analyses of 60 types of citrus whose genomes they sequenced, scientists identified 10 natural citrus …
By Jawwad A. Qureshi, Philip A. Stansly and Lukasz L. Stelinski Pest management has always been important for citrus production in Florida. It has become even more critical following invasion of the Asian citrus psyllid (ACP) and citrus leafminer (CLM), due to their association with huanglongbing (HLB or citrus greening) and canker diseases, respectively. ACP and CLM develop and reproduce …
By Robin Koestoyo, University of Florida Institute of Food and Agricultural Sciences An inventive fruit tree researcher has joined the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center. Lorenzo Rossi is the center’s first-ever root biology professor and will support the university’s statewide Institute of Food and Agricultural Sciences’ commitment to restore Florida’s $9 …
With citrus greening devastating Florida’s $8.6 billion-a-year citrus industry, three University of Florida scientists will use $10.52 million in federal grants to study ways to help growers cope with the disease, including research on genetic editing that may produce potentially resistant fruit and trees. Since greening — or huanglongbing (HLB) — was first reported in Florida in 2005, Florida’s citrus …
The U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA) announced awards to combat citrus greening disease. The funding to support research and Extension programs is made through the emergency Citrus Disease Research and Extension Program (CDRE). CDRE was authorized as part of the 2014 Farm Bill. “The need to advance research and Extension to develop management …
On Jan. 1, 2018, the California Department of Food and Agriculture (CDFA) implemented an emergency regional quarantine to more effectively protect California citrus from huanglongbing (HLB) disease. The quarantine created seven zones: 1) counties where HLB has not been detected and are not next to citrus-producing counties or the Mexican border; 2, 3 and 4) counties widely infested with ACP …
By Len Wilcox The grower-funded California Citrus Research Board (CRB) is celebrating its 50th anniversary this year. Headquartered in the Central Valley city of Visalia, under the direction of president/CEO Gary Schulz, the CRB awards more than $7 million each year to researchers throughout California. Since 2008, CRB has focused much of its efforts on huanglongbing (HLB), with approximately $33 …
University of California Riverside (UCR) is committed to a major offensive against huanglongbing (HLB, or citrus greening disease), as the threat is marching ever closer to commercial citrus orchards in California. The only confirmed cases in Southern California have been in residential trees in Los Angeles and Orange counties, including near the UCR campus. But some experts believe it is …
Grafted orange trees showcased at the 100th anniversary of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) may give the state’s citrus growers new reason to hope the industry can cope with the citrus greening crisis, UF/IFAS researchers say. University of Florida scientists and Tropicana are teaming up to test promising new UF/IFAS-bred …
