The U.S. Department of Agriculture (USDA) is soliciting continuous nominations for membership to its National Agricultural Research, Extension, Education and Economics (NAREEE) Advisory Board and its committees. The NAREEE board is comprised of 15 members representing a specific category of U.S. agricultural stakeholders. The board’s three committees include the Specialty Crop Committee, Citrus Disease Subcommittee and National Genetic Resources Advisory …
By Ben Albritton Florida’s farmers depend on healthy soil and clean water to produce crops. It’s how my family has grown citrus, strawberries and cattle for more than four generations. The quality of our natural resources has a direct impact on our crops and livelihood. I am a fifth-generation Floridian who was raised by a line of farmers, ranchers and …
Citrus acreage continues to increase across the North Florida, South Georgia and South Alabama regions. Interest has expanded to large row crop farmers, who see citrus as a viable alternative crop, said Kim Jones at the Feb. 17 Citrus Health Forum meeting at the University of Florida Institute of Food and Agricultural Sciences North Florida Research and Education Center. Jones …
By Megan Dewdney Spring is around the corner, and Florida’s first wave of bloom is here. But there is no time to relax and enjoy the flowers because citrus diseases wait for no grower. Young fruitlets become susceptible to canker toward the end of March to the beginning of April. Missing that key window of protection — if the weather …
The pathogen phytophthora has long presented problems for Florida citrus growers. But the HLB disease that has plagued Florida since 2005 reduces the efficacy of phytophthora management, citrus pathologist Ozgur Batuman reported in a recent virtual seminar. Batuman, who works for the University of Florida Institute of Food and Agricultural Sciences, said improved fungicide timing, number of applications and rates …
By Megan Dewdney Mid-summer to fall has become algal spot season in my office. The disease is re-emerging in Florida for unknown reasons. While much of the year algal spot is low key and hard to spot, between June and September it is very obvious. So, what is algal spot, should you be concerned, and what can you do about …
The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has revised the conditions for interstate movement of citrus fruit from areas quarantined for both sweet orange scab (Elsinöe australis, SOS) and citrus canker (Xanthomonas axonopodis, CC). The revisions allow for the movement of fruit to packinghouses located in contiguous states that are not quarantined for either disease. …
Alabama Cooperative Extension implores growers to be on the lookout for symptoms of citrus canker disease in their trees. Commercial growers need to scout their trees regularly to stop the disease’s potential spread, says Kassie Conner, Alabama Extension specialist. “What we need people to do right now is look for these symptoms and report it if they find it,” Conner …
By Christopher Vincent, Megan Dewdney and Liliana Cano Bingo is a relatively new and unfamiliar variety, which growers initially sought as a positive alternative. However, it presents some unique production challenges. Bingo is desirable because its high-quality, low-seeded fruits are ripe in October, a valuable harvest window for Florida growers. But in the early years of its propagation, some nurseries …
By Lindy Savelle Earlier this year, a small grove owner in Grady County, Georgia, noticed some odd-looking trees in his grove. The leaves, having an asymmetrical discoloration, appeared to be nutritionally deficient. In an attempt to remedy the problem, the grower reached out to the Grady County Extension office for help. The Extension agent began his quest to figure out …
By Ozgur Batuman, Sanju Kunwar and Ana Redondo There are new products that potentially can be added to a grower’s toolbox in coming seasons for managing citrus bacterial canker. Citrus canker is an infection by a species of bacteria (Xanthomonas citri subsp. citri) that causes fruit blemishes and fruit drop. It makes fruit unsightly and lowers its marketability. Every year, …
There are many materials that will kill the bacteria (Candidatus Liberibacter asiaticus) that causes HLB. The challenge has been getting these materials to the place where the bacteria lives in citrus trees — the phloem. Some believe trunk injection might do the trick, but it is an expensive and labor-intensive practice that has limited any breakthroughs so far. During the …
A new study published by the Centers for Disease Control and Prevention (CDC) found that only a small percentage of U.S. adults consume the recommended amount of fruits and vegetables. On average only 12% of U.S. adults meet fruit-intake and only 10% meet vegetable-intake recommendations outlined in the 2020-2025 Dietary Guidelines for Americans (DGA). Low intakes may put Americans at increased risk …
Alico, Inc. has seen an increase in the price per pound solids for oranges from $2.25 to $2.58 so far this season. A significant reason for the price improvement is the continued strength of consumption of not-from-concentrate orange juice by retail consumers, the company stated. Average pound solids per box were down for the fiscal quarter that ended Dec. 31, 2021. The pounds …
By Megan M. Dewdney Postbloom fruit drop (PFD) is a flower disease mainly caused by the fungus Colletotrichum acutatum. The fungus is present on citrus trees throughout the year but survives by producing resting structures on leaves and stems. The fungus becomes stimulated to produce spores by substances from the early flowers. These early spores infect the initial flowers and …
The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) and the Texas Department of Agriculture (TDA) have established five new quarantine areas for citrus canker in Brazoria, Galveston and Harris counties, Texas. They also expanded two existing quarantine areas for citrus canker in Brazoria, Fort Bend and Harris Counties, Texas, to prevent the spread of the disease. …
Rick Dantzler, chief operating officer of the Citrus Research and Development Foundation (CRDF), gave an update at the recent Florida Citrus Show on the latest efforts to find solutions to the HLB problem. Dantzler acknowledged the frustration growers have expressed in the long battle against the disease and the challenge it has presented to the research community. Because of this, …
Individual protective covers (IPCs) on citrus trees have become a more common sight in Florida groves in recent years. The bags that cover young trees exclude the Asian citrus psyllid (ACP) from feeding on the plants, thus protecting them from HLB. Some estimates suggest that more than 1 million IPCs are now deployed in the state’s citrus groves. During the …
Citrus leprosis has not been reported in Florida since 1968, but researcher Ozgur Batuman called it “an approaching threat to Florida citrus” in a recent virtual seminar. Batuman, a citrus pathologist at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center, urged growers to be on the lookout for the disease. According …
