PIECES OF THE PAST: Marching On
By Brenda Eubanks Burnette March usually signals the annual Florida Citrus Hall of Fame Induction Luncheon, honoring those individuals who have made significant contributions to the state’s citrus industry. Like so many other things, COVID-19 changed that. This year, the celebration has been postponed to Friday, Nov. 5. Although it will still be at Florida Southern College, it will be …
Protect Young Citrus from Weeds
Protect Young Citrus from Grasses, Broadleaf Weeds & Nutsedge Weeds in citrus groves can cause yield loss of up to 33%, according to research published by the University of Florida (UF) Citrus Research & Education Center. This significant – yet largely preventable – level of yield loss can be due to weeds that interfere with harvesting, serve as alternate hosts …
OJ Sales One Year into the Pandemic
Florida Citrus Commission Chairman Steve Johnson recently discussed the COVID-19 pandemic’s impact on sales of Florida orange juice (OJ). “We witnessed sales (of OJ) soar in the initial weeks (of the pandemic) as consumers stockpiled their pantries with kitchen staples and sought out healthy foods and beverages that provide immune support,” Johnson reported in an email to members of …
HLB Control: A New Potential Method
A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher has found a material that can be used to silence essential genes within Asian citrus psyllids and in the HLB-causing bacterial pathogen that the psyllids spread. The material is 2’-deoxy-2’-flouro-d-arabinonucleic acid antisense oligonucleotides (FANA ASO), small-sized single-stranded nucleic acids. The discovery was made by Kirsten Pelz-Stelinski, an associate …
Panhandle Growers Experience Scales
Many citrus growers in Florida’s panhandle were experiencing high populations of scales early this year, particularly Florida red scale and false Florida red scale, Jefferson County Extension agent Danielle Sprague announced in a recent issue of the Cold Hardy Citrus Connection newsletter. The newsletter is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension publication. Sprague pointed …
Time to Check Under the Hood for Nematodes
By Larry Duncan Monitoring population levels of plant parasitic nematodes and phytophthora is best done in springtime prior to the rainy season. Peak population density of the citrus nematode (Tylenchulus semipentrans) occurs at that time, and the accuracy of sample results increases with population density. The sampled population levels of this nematode and those of Phytophthora spp. can be compared …
Biological Controls for Lebbeck Mealybug
Lebbeck mealybug (Nipaecoccus viridis) was first identified in Florida citrus in 2019 in Highlands County. It has now been documented in commercial citrus groves in 11 counties and in dooryard citrus plantings in two counties. While lebbeck mealybug can feed on most of the above-ground parts of a citrus tree, it is most damaging in the canopy, where it feeds …
Field Trials for Cultivar Evaluation; Soil and Root Health
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus researchers are collaborating on ground-breaking research projects to fight against HLB. They are working with researchers at the University of California-Riverside (UC-Riverside), Texas A&M and Washington State University on a project to field-test new citrus cultivars for tolerance or resistance to HLB. The research is funded by the U.S. …
Decline in 100% Fruit Juice Consumption
A new research report shows that Americans continue to consume fewer fruits and vegetables despite consistent dietary advice to the contrary. An accompanying decline in the consumption of 100% fruit juice, such as orange juice (OJ), is likely a significant contributor to the issue. The Produce for Better Health Foundation (PBH) reported in its “State of the Plate: America’s Fruit …
Irrigation and Nutrition Management in the Era of HLB
A solid nutrition and irrigation program can enhance the productivity of HLB-affected trees and improve citrus tree health, potentially making production profitable even under HLB conditions. This was the subject of Davie Kadyampakeni’s talk during a March 9 OJ Break virtual meeting held for citrus growers. Kadyampakeni is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant …
Conservation Program Improvements
The application deadline for the U.S. Department of Agriculture’s (USDA) Conservation Stewardship Program (CSP) is March 26 for fiscal year 2021. Through CSP, USDA’s Natural Resources Conservation Service (NRCS) helps agricultural producers and forest landowners earn payments for expanding conservation activities while maintaining agricultural production on their land. CSP also encourages adoption of new technologies and management techniques. Changes …
Canopy Management to Improve Fresh Fruit
A new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) document, Management of Citrus Tree Canopies for Fresh-Fruit Production, addresses the principles of citrus pruning and canopy management. It tells how applying those principles can improve the quality and quantity of fresh fruit production in Florida. Here is an excerpt from the document: “Canopy management has three goals …
Grapefruit Part of Tariff Suspension
Florida grapefruit grower and packer Dan Richey hopes a recently announced four-month suspension of tariffs on U.S. products shipped to the European Union (EU), including grapefruit, will become permanent. The EU and the United States on March 5 agreed on the mutual four-month suspension of the tariffs related to World Trade Organization (WTO) aircraft disputes. The suspension will cover all …
Groups Sue EPA Over Aldicarb Decision
Three organizations on March 3 sued the U.S. Environmental Protection Agency (EPA) over its decision in the final days of the Trump administration to reapprove previously cancelled uses of the pesticide aldicarb on Florida oranges and grapefruit. The Farmworker Association of Florida, the Center for Biological Diversity and the Environmental Working Group filed the suit in the District of Columbia …
Changes to U.S. Orange Crop Forecast
Florida’s orange crop forecast was reduced by 500,000 boxes to 55.5 million boxes in the U.S. Department of Agriculture’s (USDA) March 9 citrus crop forecast. This represents a 1% reduction from the February forecast. If the March projection is realized, it will be 18% lower than last season’s final production. Florida’s Valencia orange crop forecast was reduced by 1 million …
Disaster Assistance Programs for Citrus
Two disaster assistance programs available to citrus growers were discussed during the virtual 2021 Louisiana State University AgCenter Citrus Symposium. The Noninsured Crop Disaster Assistance Program (NAP) and the Tree Assistance Program (TAP) are both offered by the U.S. Department of Agriculture’s Farm Services Agency (USDA-FSA). Jamie Rodreguez, a USDA-FSA county executive director in Louisiana, made the presentation. Rodreguez said …
Scout for Scale and Mealybug Crawlers
By Lauren Diepenbrock While scale and mealybug pests commonly found in citrus have historically been controlled by predators and parasites, management advice for this group of insects is often requested. There are likely several underlying factors to these insects becoming more frequently encountered. This includes changes in insecticide management practices, changes in nutritional management, and increased scouting due to the …
