Below you'll see everything we could locate for your search of “Asian citrus psyllid”
An innovative way to manage huanglongbing (HLB) disease is producing impressive results in University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research. According to Arnold Schumann, UF/IFAS professor at the Citrus Research and Education Center (CREC), citrus under protective screen (CUPS) production systems have increased yields with zero effect from HLB. He shared research results during a recent …
Florida citrus growers have known for several years that individual protective covers (IPCs) do a good job of excluding HLB-spreading Asian citrus psyllids from young trees. “But those protective covers also protect from things like Diaprepes abbreviatus,” researcher Larry Duncan told the recent Citrus Expo audience. Duncan is a nematologist at the University of Florida Institute of Food and Agricultural …
The glassy-winged sharpshooter (GWSS) is a pest that made California headlines from the late 1980s until its suppression at the turn of the new century. Unfortunately, it made a fast comeback in 2020, probably due to unusually warm winter weather. A warm winter and spring caused populations in the southern San Joaquin Valley to surge. Kern County traps showed a …
A modified way of producing citrus in Florida to protect against the Asian citrus psyllid may provide shelter for another pest — chilli thrips. Citrus under protective screen (CUPS) production systems protect against the psyllid and the huanglongbing (HLB) disease the pest transmits. However, according to University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lauren Diepenbrock, the …
By Fernando Alferez, Ozgur Batuman, Susmita Gaire, Ute Albrecht and Jawwad Qureshi In previous and ongoing research performed at the Southwest Florida Research and Education Center (SWFREC), we have demonstrated that individual protective covers (IPCs) are effective in keeping psyllids off newly planted citrus trees. Trees have been HLB-free for more than two years after planting, and the IPCs provide …
The California Department of Food and Agriculture (CDFA) has declared a quarantine in north San Diego County following the detection of the citrus disease huanglongbing (HLB), known as citrus greening. The disease was found in two citrus trees on one residential property in the city of Oceanside. This is the first time the plant disease, which does not harm people …
California’s efforts to keep huanglongbing (HLB) at bay have been largely successful. So far, the state’s huge citrus industry has avoided the devastating loss of trees that has occurred in Florida, South America and other commercial citrus-growing regions around the world. However, those efforts have come with a cost to citrus growers. Bruce Babcock, professor of public policy at University …
By Rhuanito S. Ferrarezi, J. Martin Zapien-Macias, Mac Hossain, Tom James, Ronald D. Cave, Peter Spyke, William S. Castle, Jude W. Grosser, Fred Gmitter and Ed Stover In the last decade, huanglongbing (HLB) has reduced production of Florida grapefruit by 75%, mandarin by 78% and sweet orange by 52%. This decrease is significant for the Indian River District, which produces …
Rick Dantzler did not follow normal protocol in providing an update about his organization’s efforts. Dantzler, chief operating officer of the Citrus Research and Development Foundation (CRDF), didn’t talk glowingly about CRDF’s accomplishments. Rather, he started off by telling how far the Florida citrus industry has declined since CRDF was formed in 2009 primarily to find a solution to HLB. …
The recent annual report from California’s Citrus Pest & Disease Prevention Program (CPDPP) offered insights into ways the state’s citrus industry has kept HLB out of commercial groves. Jim Gorden, chair of the group’s Citrus Pest & Disease Prevention Committee, stated that the California industry has “invested countless hours, leveraged millions of dollars and created dozens of innovative partnerships” in …
Shifting consumer trends have helped dictate which varieties are most popular among California citrus growers. Bruce Babcock, professor in the School of Public Policy at University of California, Riverside, explained that over the past 15 years or so, there have been some notable changes in California citrus acreage. “What we’ve seen is just explosive growth in acreage devoted to mandarins. …
By Davie Kadyampakeni and Sandra Guzmán Young citrus trees require optimal irrigation management for vigorous vegetative growth, leaf flushing and the establishment of a dense canopy. Poor practices such as infrequent irrigation or not using irrigation scheduling tools could be costly. Young tree growth also could be impacted by excessive water and nutrient losses. Crop water stress in young trees …
Hardee County, Florida, orange grower Kenny Sanders saw his orange production dip in the 2020-21 season compared to the prior year. However, he still made a good profit, thanks to strong fruit prices. “I went down from 400 boxes an acre to 308 boxes, which I can live with, but it’s not as nice,” Sanders said. “We had a good …
Beneficial insects could be a citrus grower’s best friend. In a time when producers are applying insecticides to control the Asian citrus psyllid, the vector of citrus greening disease, it’s important to preserve the psyllids’ natural enemies, like lady beetles and lacewings. Jawwad Qureshi, University of Florida entomologist, implores growers to scout their groves periodically to see what insects are …
By Lauren Diepenbrock Lebbeck mealybugs (Nipaecoccus viridis) have quickly made an impact on citrus groves in Central and South Florida since the pest was first found in 2019. While management techniques are still being studied, this article describes actions growers can take to find this pest before it becomes a problem. SOOTY MOLDLebbeck mealybugs excrete sugary honeydew, much like many …
Florida growers are being asked to take a survey on the use of cover crops and reflective mulch in citrus production. These systems are being investigated as potential means to improve soil health and reduce pest pressure from Asian citrus psyllids, which transmit the destructive citrus disease HLB. The survey is being conducted by researchers with the University of Florida Institute …
As temperatures increase across Florida, so does the risk for huanglongbing (HLB) disease, known as citrus greening. While the southern and central portions of the state remain vulnerable to HLB and Asian citrus psyllids (ACP) that spread the disease, growers in North Florida and South Georgia have so far been spared. But Xavier Martini, University of Florida entomologist at the …
Two Florida citrus grower associations expressed disappointment over the recent Florida Department of Agriculture and Consumer Services’ (FDACS) decision to deny the use of the pesticide aldicarb in Florida citrus. “We are frustrated in the decision as we believe aldicarb will provide a powerful tool in the fight against citrus greening and can be used safely,” said Florida Citrus Mutual …
By Owen “Sonny” Conner The two greatest challenges of the last 20 years, for me as a citrus grower, have been HLB and foreign competition depressing prices. Citrus growers had never faced a disease threat even approaching the devastating effects HLB has had on the industry. It was the industry killer we all feared would one day raise its ugly …
Two growers expressed different views about the recent decision to deny the use of the pesticide aldicarb in Florida citrus. The denial was made by the Florida Department of Agriculture and Consumer Services (FDACS). One termed the decision “disappointing.” The other referred to it as a “a blessing.” “It is disappointing to lose any tool that would strengthen our existing …
