The U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA) announced an investment of nearly $11 million for research to combat HLB. “NIFA’s Emergency Citrus Disease Research and Extension program brings the nation’s top scientists together with citrus industry representatives to find scientifically sound solutions to combat and prevent HLB at the farm-level,” said NIFA Director Carrie …
By Ariel Singerman, Stephen H. Futch and Brandon Page This article provides estimates on the performance of different rootstocks grafted with Valencia sweet orange scions in commercial field conditions. These are the first estimates obtained from side-by-side trials that compare the performance of rootstocks developed by two breeding programs: The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) …
The important process that gets new citrus varieties in the hands of growers is the main topic of the November episode of the All In For Citrus podcast. Michael Rogers, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) director, discusses the recent CREC open house where breeders displayed potential new varieties for …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers gave a crowd of growers suggestions that can help keep citrus trees healthy. The panel discussion was part of the Nov. 16 open house and field day at the UF/IFAS Citrus Research and Education Center in Lake Alfred. HLB-affected trees need enhanced nutrition “throughout the growing season,” said horticulturist …
Lebbeck mealybug was first found causing damage in Florida citrus in Highlands County in 2019. As of this writing, it has now been found on citrus in 14 counties in Florida. This pest likely gains some dispersal assistance from wind events, either being blown on infested plant material or as crawlers on wind currents as has been noted for scale …
Fred Gmitter and Jude Grosser discuss some relatively new varieties they like – a mandarin, some oranges and a pummelo-grapefruit hybrid.

By Chris Oswalt The weather folks are predicting weak to moderate La Niña conditions this winter. Typically, having either the La Niña or El Niño conditions during the winter in Florida is a good thing. There is a historically lower probability of having severe freezing temperatures during either of these El Niño-Southern Oscillation (ENSO) conditions in Florida. What this means …
By Ramdas Kanissery, Nirmal Timilsina and Mongi Zekri Weed control is crucial for the growth and establishment of young citrus trees. Chemical weed control with herbicides is an efficient and cost-effective method for managing weeds in newly planted groves. However, before applying herbicide products, care must be taken to avoid damaging young trees and newly planted resets. Every so often, …
Information to help growers find and control citrus black spot (CBS), as well as CBS regulatory procedures, were provided in an Oct. 26 training workshop in Arcadia.

University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) plant pathologist Megan Dewdney discussed the pest’s lifecycle, potential spread due to …
Plant breeders Fred Gmitter and Jude Grosser report on their efforts to develop rootstocks that perform well in Florida from several perspectives. In addition to seeking tolerance to HLB, they are working on rootstocks that might control tree size, deal with other diseases and pests and perform in a range of soils. Gmitter and Grosser are University of Florida Institute …
Planting of new improved citrus scion/rootstock combinations to demonstrate sustainable and profitable citriculture is one of eight new research projects slated for the 27,000-acre DeLuca Preserve in Osceola County, Florida. The rootstocks and scions will come from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center citrus breeding program. The eight projects are …
In the search for solutions to HLB, a formulation based on oak leaf extract has been developed by citrus growers Travis Murphy and Tom Thayer, the Indian River Citrus League’s October River Ramblings newsletter reported.

By Yiannis Ampatzidis and Ute Albrecht Optimizing nutrition is important for tree health and productivity and can improve tolerance to stresses and diseases. Good nutrient management requires regular field monitoring to identify problems and examine crop responses. Leaves need to be collected and sent to a specialized laboratory for detailed information on macronutrients and micronutrients, which is time-consuming and costly. …
One of the unique ways of managing citrus greening disease developed by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers is not for all producers. Citrus under protective screen (CUPS) is just too expensive for all growers to take advantage of, says Fred Gmitter, a UF/IFAS citrus breeder. “It’s an extremely expensive investment,” Gmitter says. “For that …
