The February Florida orange forecast released by the U.S. Department of Agriculture (USDA) is 56 million boxes, up 2 million boxes from the January forecast. This represents a 4 percent increase from the January forecast. If realized, it will be 17 percent less than last season’s final production. ORANGESThe forecast change was for non-Valencia production, which now stands at 22 …
Florida’s citrus growers are counting on research to help sustain what’s left of an industry decimated by huanglongbing (HLB). The disease remains a focal point of research at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Scott Angle, vice president for agriculture and natural resources at UF/IFAS, understands the ramifications if improved HLB management options aren’t available …
By Andre B. Gama and Megan M. Dewdney Postbloom fruit drop (PFD) of citrus is a disease caused mostly by the fungus Colletotrichum acutatum. This fungus survives by producing resting structures on leaves and stems. When flowers start to appear in groves, these resting structures produce spores that can cause PFD. However, the fungus requires specific weather conditions to be …
The Cold Hardy Citrus Association (CHCA), founded in 2017, was established to ensure all growers, large and small, have a unified voice in an emerging industry and to provide education on best management practices in light of HLB. CHCA members include growers, packers, processors, industry suppliers, nurseries, consultants, homeowners and academia representing Florida, Georgia, Alabama, Louisiana and Mississippi. Kim Jones …
By Megan Dewdney There were many challenges in 2020, but fortunately the Florida season for foliar citrus diseases was relatively normal. Little to no postbloom fruit drop (PFD) was reported during the 2020 bloom because of a sudden dry spell as the flowers opened. As spring 2021 approaches, the forecast is for a La Niña weather pattern with slightly warmer …
Field tests of numerous antibacterial products and plant-derived compounds are underway with the goal of eliminating the HLB-causing bacteria in citrus and reversing plant damage to restore tree health. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) plant root biologist Lorenzo Rossi discusses a new research project funded by the U.S. Department of Agriculture’s (USDA) National Institute of …
Two University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers will study citrus roots and stems to improve photosynthesis in plant leaves. Christopher Vincent and Fred Gmitter hope to find the optimal relationship between citrus tree “sources” and “sinks” so that plant breeders can select varieties — and growers can use practices — that lead to faster-growing plants. …
By Brenda Eubanks Burnette In January, the Florida Department of Agriculture and Consumer Services (FDACS) hosted virtual “Florida Citrus Squeeze” events at elementary schools throughout Florida with Chef Paula Kendrick and Miss Florida Citrus Leila Sabet. The program was announced in December to Florida food service personnel and teachers that participate in the division’s Harvest of the Month Program. Participating …
The citrus industry is expanding in Georgia. With that growth comes the need to slow the spread of the Asian citrus psyllid (ACP), the vector of HLB disease. Although not yet found in Georgia’s commercial citrus production, there have been confirmed HLB-positive residential citrus trees. The disease has the potential to greatly hinder the state’s citrus industry. Therefore, University of …
Citrus fruit drop before harvest has been a perennial problem for Florida growers but has been particularly challenging this season. Tripti Vashisth and Fernando Alferez of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) will present their latest research on fruit drop and answer questions from growers in a Zoom seminar on Feb. 16. The seminar is …
Citrus Extension agent Chris Oswalt reports the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is determining the acclimation of Florida citrus trees to cold weather by measuring citrus leaf freezing temperatures. “Certain environmental conditions will initiate this acclimation process,” says Oswalt. “These environmental cues will cause physiological changes to occur within the plant that will depress the …
By Megan Dewdney, Tripti Vashisth and Lauren Diepenbrock Dead wood has long been challenging for fresh citrus fruit production. Spores in twigs can form which cause blemishing diseases that downgrade fruit for lower profits. More recently, it has come to light that there are horticultural and entomological reasons to remove this wood as well. Many growers are familiar with melanose, …
By Clint Thompson Increased interest in biologicals stems from their long-term sustainability and the belief that synthetic materials have reached their ceiling of productivity. Tate McPherson, vice president of marketing and business development at Douglas Plant Health (DPH), shares those sentiments about biologicals, which represent a group of products derived from living organisms. Farmers utilize these environmentally friendly products in …
By Ajia Paolillo Editor’s note: This article grants one continuing education unit (CEU) in the Core category toward the renewal of a Florida Department of Agriculture and Consumer Services restricted-use pesticide license when the accompanying test is submitted and approved. Integrated pest management (IPM) uses a combination of methods to keep pest populations at an acceptable level, which are economical …
Mike Sparks, Florida Citrus Mutual executive vice president/CEO, reported that the U.S. Department of Agriculture (USDA) announced another round of citrus purchases totaling almost $48 million. The breakdown includes $10 million worth of orange juice, $7.5 million worth of grapefruit juice, $25 million in fresh oranges and $5 million in fresh grapefruit. The USDA purchases will be for distribution to …
Visual identification of nutrient deficiencies and leaf damage is an important diagnostic tool for fine-tuning management of citrus. Arnold Schumann, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor, shared how UF/IFAS researchers have used artificial intelligence (AI) to diagnose citrus nutritional deficiencies, diseases and pest damage. According to Schumann, disease and pest symptoms on leaves may cause …
By Brenda Eubanks Burnette I grew up in Winter Haven and have driven by Waverly Growers Cooperative countless times when traveling around Polk County. But I never knew that at one time there was a formal garden and picnic grounds adjacent to the Waverly Welcome House. Founded in 1914 by a group of local growers led by Charles Hillery Walker …
The Citrus Research and Development Foundation (CRDF) directors recently ratified the rootstock selections for the planned rootstock field trials and discussed the organization’s involvement in future research, CRDF Chief Operating Officer Rick Dantzler reported. The board ratified 10 rootstock selections for the new field trials, overseen by CRDF’s Select Committee on Plant Improvement. According to Dantzler, the field trials will evaluate …
By Lauren M. Diepenbrock While there are many species of ants in Florida, the invasive fire ant (Solenopsis invicta) is the one most people are familiar with. These ants can be pests in agriculture, landscapes and structures. The pest’s ability to use a variety of habitats and resources makes it challenging to manage. In citrus groves, fire ants can be …
While everyone strives to protect themselves from coronavirus disease, growers have an additional concern: protecting their trees from citrus disease. While HLB is of course the most damaging disease of citrus, there are other diseases that should not be overlooked. Disease management is the theme of the February 2021 issue of Citrus Industry magazine. University of Florida Institute of Food …
