GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have found a new way to detect immature citrus 83 percent of the time, which lets growers know where to apply fertilizer and water and perhaps save on labor costs for the $10.9 billion-a-year Florida industry. By detecting green, immature citrus more accurately and efficiently, …
GAINESVILLE, Fla. — A University of Florida Institute of Food and Agricultural Sciences researcher who uses steam to help treat citrus trees infected by greening will receive this year’s Citrus Engineer of the Year Award. Reza Ehsani, a UF/IFAS associate professor of agricultural and biological engineering, will receive the award June 21 at the 59th Biennial Citrus Engineering Symposium at …

Following an international search for a …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) recently hosted a field day and seminar on citrus under protective screen (CUPS) and individual protective covers at the Citrus Research and Education Center in Lake Alfred. While CUPS exclude the HLB-spreading Asian citrus psyllids from the structures, other pests can slip through the mesh barrier and cause problems. …
The November issue of Specialty Crop Grower magazine features a Citrus Industry section with insights on protected production, promising citrus genetics, industry research priorities and more. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers explore how the microclimate inside citrus under protective screen structures contributes to higher yields and better fruit quality. Research shows that the screens …
Citrus under protective screen (CUPS) provides citrus growers with a way to overcome the challenges of huanglongbing (HLB) disease. While grapefruit is the predominant variety grown in CUPS, research is underway to expand the varieties grown under screen. That’s one of the remaining CUPS research hurdles for Arnold Schumann, professor of soil fertility and water quality at the University of …
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 …
Citrus under protective screen (CUPS) has proven its effectiveness in helping Florida citrus producers overcome citrus greening disease. Its place in the cold-hardy citrus region remains a question, however. Arnold Schumann, professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center and leading CUPS researcher, discussed the potential for CUPS in the …
By Noor Ul Basar, Muhammad Adnan Shahid, Duplicate Sambani and Davie M. Kadyampakeni Huanglongbing (HLB) remains the greatest challenge facing citrus production in Florida. While there is currently no cure for HLB, effective management of affected trees remains a primary focus for Florida citrus growers. Efficient nutrient management is an important strategy for maintaining the health and productivity of HLB-affected …
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 …
By Megan M. Dewdney, Eva L. Mulandesa and Mark A. Ritenour Greasy-green began to be reported as a problem in Florida by fresh fruit packers and growers around 2020. The disorder, with green blotches on the grapefruit surface, appeared to be different from other known rind disorders. The effect was costly for growers and packers, with reported losses between $20,000 …
By Tripti Vashisth, Mary Sutton and Taylor Livingston Author’s note: This Tip of the Week applies to HLB-affected sweet oranges in Florida. Preharvest fruit drop remains a major concern for HLB-affected sweet oranges. Research shows that both gibberellic acid (GA) and 2,4-D can help reduce fruit drop, but the combination of GA and 2,4-D provides the greatest reduction. In a …
A new initiative aims to strengthen the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) ability to respond rapidly when a new invasive pest or plant disease threatens. Edward “Gilly” Evans, director of the UF/IFAS Tropical Research and Education Center (TREC), launched the Challenge 250 initiative. Named in recognition of the nation’s 250th anniversary, it aims to raise …

Despite cancer-related ills in recent years, citrus breeder Fred Gmitter continued his work passion, which included development of trees that were more tolerant of or resistant to HLB. “That was our mission,” said Jude Grosser, his fellow citrus breeder at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center. Grosser said Gmitter continued …
By Christopher Vincent and Rashmi Kumari Florida summers come with intense sunlight, high temperatures and frequent rain. Just as people use sunscreen to protect exposed skin from intense sunlight, plants can benefit from a protective coating on exposed leaf and fruit surfaces. One way to provide this protection is by spraying a kaolin clay particle film on the tree. Although …
