The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) recently hosted a citrus under protective screen (CUPS) and individual protective covers (IPCs) field day at the Citrus Research and Education Center in Lake Alfred. The two approaches have proven effective in excluding the Asian citrus psyllid and HLB disease from trees. During the event, a panel discussion featured …
Controlled-release fertilizers (CRFs) may help improve leaf nutrition in citrus trees affected by huanglongbing (HLB), but choosing the right fertilizer program is critical to maintaining yields, according to new research. A University of Florida Institute of Food and Agricultural Sciences study compared two CRF programs with a conventional fertilizer program in mature Valencia sweet orange trees growing in Florida’s sandy …
Sponsored Content The world today is experiencing significant geopolitical turmoil. For the Florida citrus industry, one important question is how to turn this uncertainty into an opportunity. While the United States is certainly not immune to global challenges, our country remains in a relatively strong position compared to many others. The United States has become the world’s largest producer of …
A new study suggests that tackling both the bacterium responsible for huanglongbing (HLB) and the tree’s own response to infection may offer a better path for managing the disease. A report on the research — “Combating citrus greening disease by simultaneously targeting the pathogen and callose-mediated phloem occlusion” — examines how the disease disrupts the movement of sugars through citrus …
On the cusp of another harvest season, Lindy Savelle, executive director of the Georgia Citrus Association, believes there will be a bumper crop in the South Georgia, North Florida and South Alabama areas. “I’ve not talked to a single person who has said, ‘I’m not going to have fruit this year’ — not with satsumas and not with Cara Caras. …
Florida Citrus Mutual and the Citrus Research and Field Trial (CRAFT) Foundation held joint board and field meetings in Fort Pierce on Oct. 15.

The day began at Picos Farm, an experimental research site at the …
The 2026 Citrus Achievement Award winner, Ned Hancock, has seen his groves and acreage decline over the past 20 years as HLB has ravaged the Florida citrus industry. But he believes there are some positive signs pointing the industry in the right direction. This year’s final crop estimate, putting production slightly ahead of the previous year, was among those positive …
Citrus growers and researchers know that oxytetracycline (OTC) trunk injection can reduce the amount of the bacterium associated with huanglongbing (HLB) disease and improve fruit production and juice quality. However, new research shows the treatment also causes changes in microbial functions around citrus roots. Researchers conducted a field study in a commercial Southwest Florida orchard containing 8-year-old Valencia sweet orange …
In 2025, high school student Tanishka Aglave regaled the Highlands County Citrus Growers Association (HCCGA) annual meeting with a discussion of her prize-winning investigation into a natural alternative treatment for HLB. Instead of using the standard HLB treatment oxytetracycline (OTC) as a trunk injection, she injected HLB-infected trees with an extract from the Indian curry leaf plant. She reported that …

Efficient nutrient management is an important strategy for maintaining the health and productivity of HLB-affected …
By Peter Chaires Growers and nurserymen have come to understand that citrus breeding is a continuum. It can’t be turned on and off like a light switch. Though priorities of emphasis, available techniques, tools and technologies may change, large shifts in breeding objectives take time and can produce delays and inefficiencies. Making crosses is a relatively quick process. Knowledgeable breeders …
In the long battle against HLB, there have been no tactics as successful at safeguarding citrus trees as protective screen. Citrus under protective screen (CUPS) structures can exclude the Asian citrus psyllid (ACP) and HLB from entire blocks, while individual protective covers (IPCs) can keep individual trees free of HLB for the critical first few years after planting. In early …
