Summer Tree Care Practices to Improve Fruit Quality and Yield
By Fernando Alferez and Tripti Vashisth As summer approaches and citrus trees bear developing fruit, growers can engage in several practices to improve fruit quality and yield. As temperatures rise and daylength increases, conditions are conducive for enhanced photosynthesis and accumulation of soluble sugars in the fruit. It is important to note that, in general, the temperature is negatively correlated …
Psyllids May Give a Year’s Warning of HLB
Although huanglongbing (HLB) disease was detected in Florida citrus in 2005, the HLB bacterium wasn’t found in Texas until 2011, when scientists detected it in Asian citrus psyllids (ACP). The disease wasn’t found in Texas citrus trees until 2012, suggesting that the HLB-spreading psyllids may be used for early detection of the pathogen in newly invaded areas. Factors influencing the spread …
How Growers Can Protect Pollinators
Florida’s U.S. Department of Agriculture Natural Resources Conservation Service (USDA/NRCS) recently recognized pollinators and the growers who create and maintain their habitat. “Pollinators, such as honeybees, bumblebees, butterflies, birds, bats, flies and many others, play a critical role in crop production,” Florida’s USDA/NRCS stated in a media release. The recognition came as National Pollinator Week, June 22-28, approaches. The week …
Bill Aims to Prohibit Citrus Imports From China
Florida Congressman Greg Steube on June 11 introduced the U.S. Citrus Protection Act, legislation that would prohibit the importation of commercially produced fresh citrus fruit from China. “As farmers and ranchers in Florida and across the country are struggling to cope with the decreased demand for their products as a result of the economic shutdowns, more than ever we need to put …
Battling the Bacteria Inside Psyllids
Kirsten Pelz-Stelinski, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor, recently discussed her research on bacteria associated with Asian citrus psyllids. This includes endosymbiotic bacteria that live inside of psyllids as well as the liberibacter that causes citrus greening disease. Her research is looking at how these microorganisms can be targeted inside the psyllid to reduce …
Soil Organic Matter Helps Fight HLB
By Sean Stokes, Thomas Borch and Pankaj Trivedi The benefits of soil organic matter (SOM) in agriculture have been well documented and include both improved water and nutrient retention. SOM is also essential for a properly functioning rhizosphere microbiome. However, the natural level of SOM in the sandy, acidic soil of Florida’s citrus grove regions is often around 1 percent, …
Consumer Response to OJ During COVID-19
Yan Heng, Marisa Zansler and Lisa House have authored a new study on consumer response to orange juice (OJ) during the COVID-19 outbreak.

Zansler is the director of the Economic and …
Cost-Effective Psyllid Control Strategies
Lukasz Stelinski makes the case that reducing HLB-spreading Asian citrus psyllid (ACP) populations improves tree health — even when trees already have HLB. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist offers several tips about psyllid control in a new presentation available online. Keeping ACP populations down seems to help yield, Stelinski states. His hypothesis is …
New Opportunity for Citrus Growers to Earn CEUs Online
When the annual 2020 Florida Citrus Growers’ Institute was canceled due to the stay-at-home guidelines recommended by the state, growers were shut out of learning the latest research updates from University of Florida citrus scientists. In addition, they were denied access to earning valuable continuing education units (CEUs) needed to renew pesticide licenses. University of Florida/Institute of Food and Agricultural …
Opposition to South African Citrus Imports Into Georgia
Two associations representing Georgia citrus growers expressed strong concerns about a federal proposal to remove restrictions on the ports of entry into which South African citrus may enter the United States. Removal of port restrictions would allow the importation of the citrus into all U.S. ports, including Savannah, Georgia. The restriction removal was proposed by the U.S. Department of Agriculture’s …
A Case for an OJ Tax Hike
Florida Citrus Commission Chairman Ned Hancock on June 5 made a case for increasing the Florida Department of Citrus’ (FDOC) grower tax on oranges processed for juice. “With a new season ahead of us, we have an opportunity to not only adjust our marketing approach to fit the needs of the ever-changing consumer but also best support the Florida grower,” …
Fruit Drop of Citrus in Summer Months
By Tripti Vashisth, Megan Dewdney and Lauren Diepenbrock This article summarizes what is known about summer fruit drop in healthy citrus trees and those with huanglongbing (HLB). Also discussed is how HLB can affect early fruit development and exacerbate fruit drop. Additionally, strategies to reduce summer fruit drop are included. Citrus flowers profusely, but less than 2 percent of the …
