Florida researcher Ute Albrecht shared information about citrus tree roots at the recent Georgia Citrus Association annual conference. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor specializing in plant physiology discussed rootstocks and soils, suggested transplanting tips and touched briefly on freeze tolerance. Albrecht works at the UF/IFAS Southwest Florida Research and Education Center in …
Summer is “a field day for weeds,” Ramdas Kanissery said in a March 29 presentation about weed control for citrus. The University of Florida Institute of Food and Agricultural Sciences assistant professor provided a progressive step-by-step approach to suppressing weeds during the summer. CONTROL EXISTING WEEDSGrowers can get off to a good start by controlling existing weeds with post-emergent herbicides. …
By Lauren Diepenbrock Recently, several articles have highlighted a potential new threat to the citrus industry in Florida, the lime swallowtail. While it is true that this pest has been found in residential citrus plantings in Key West, it is unlikely that lime swallowtail will have much of an impact, if any, on Florida’s commercial citrus industry. Lime swallowtail is …
How much life lives in a tiny bit of soil? A lot, according to Sarah Strauss, assistant professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). “The estimate I often mention is there can be over a billion microorganisms in a gram of soil, which is about this size of a quarter,” she said during the …
In Brazil’s São Paulo citrus belt, infections of fruit by black spot usually occur from petal fall, in September/October, until the end of the rainy season, usually in April. Black spot can reduce production by up to 85%. Some studies have shown that the amount of fungicide applications to control black spot can be established according to the orange variety. …
The objective of a new study published in HortScience was to evaluate and understand the nutrient uptake potential of citrus rootstocks. Conducted by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers, it is one of the first citrus studies to report nutrient uptake efficiency and the potential of rootstocks. The information presented in the study can be …
Morgan McKenna Porter brings new energy to the Citrus Research and Development Foundation. By Ernie Neff New Citrus Research and Development Foundation (CRDF) board President Morgan McKenna Porter was born Feb. 29, 1992. There’s only a Feb. 29 every fourth year, a leap year. “So,” she quipped, “CRDF has a seven-year-old president if we go by my leap year age.” …
The use of individual protective covers (IPCs) to safeguard young citrus trees from HLB has become a common practice in Florida groves in recent years. Fernando Alferez, an assistant professor of citrus horticulture with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), has led the research effort to study IPCs and their effectiveness in preventing HLB. He …
By Gary England, Fred Gmitter and Manjul Dutt In 2014, most groves in Central Florida had citrus greening infection rates approaching 100%, but a Lake County grower reported that some trees in his Hamlin on Swingle blocks seemed to be relatively healthy. Some visual HLB symptoms were observed on these “surviving” trees, but they did not have the massive fall …
By Marisa L. Zansler The Florida citrus industry has endured many challenges throughout its storied history, but never more so than over the past 18 years. During this time, the devastating impact of HLB has become more apparent and entrenched as the root cause of declines in the production of oranges, grapefruit and specialty citrus. HLB, combined with recent weather-related …
Trees in the Sweet Valley Citrus region have been in high demand in recent years. Plantings of satsuma mandarins and other citrus varieties have steadily risen the past few years in Georgia, Alabama and North Florida. That steady climb is expected to stall this year, however. Following the Christmas freeze event that rattled the industry in the Southeast in December …
HLB has yet to become a major problem for Georgia’s citrus producers. Jonathan Oliver, University of Georgia assistant professor and small fruits pathologist, attributes the disease’s lack of presence in Georgia’s commercial groves to multiple factors. “It still comes down to the fact that, number one, you don’t see symptoms for a while. A lot of our trees are young,” …
By Megan Dewdney For foliar diseases, 2022 started off easily with limited outbreaks in Florida because the spring was dryer than average. The same La Niña weather pattern responsible for the dry conditions of the last two springs is predicted to occur again this winter into early spring. The weather pattern is then predicted to become a neutral pattern with …
Chinese production of tangerines/mandarins and grapefruit/pomelos in 2022–23 are both forecast to dip slightly from prior year levels. The forecast was issued by the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS). TANGERINES AND MANDARINSProduction of tangerines and mandarins is forecast at 26.5 million metric tons (MMT) in 2022–23, compared to 27 MMT the prior year. The forecast reflects …
By Ramdas Kanissery and Mahesh Bashyal Using compost and soil amendments is beneficial to Florida citrus groves. Florida soils are sandy and have a low organic matter and cation exchange capacity. Adding compost and organic amendments (e.g., humic acid) can enhance the soil’s ability to retain water and nutrients. These practices can also boost soil microbial activity and improve soil …
When commercial citrus acreage started migrating north some years ago, the big question was: To what extent would Asian citrus psyllids (ACP) and HLB migrate with the crop? With citrus getting well established in South Georgia, the pest and disease are there, but not yet at devastating levels like in Florida. Johnathan Oliver, an assistant professor of fruit pathology with …
Due to a drought, lemon production in Argentina is forecast to decline to 1.77 million metric tons (MMT) in 2022–23, down 130,000 metric tons (MT) from the prior year. The drought is expected to continue through the Southern Hemisphere summer of 2023 due in part to the third La Niña weather pattern in a row. The forecast was issued by …
The Parson Brown is an early-season sweet orange that J.L. Carney identified in 1875. By the 1920s, the variety had become a popular cultivar among growers, but eventually plantings declined as Hamlin became the go-to selection for the early season. However, because of its apparent tolerance to HLB, Parson Brown is again stirring interest among growers. Manjul Dutt, assistant professor …
Some Florida citrus growers have recently started oxytetracycline hydrochloride (OTC-HCl) injection into tree trunks to help manage HLB. Other growers are considering it. Researcher Ute Albrecht offered a list of best practices for the product’s use during a Jan. 31 presentation in Immokalee. The presentation was made at the University of Florida Institute of Food and Agricultural Sciences Southwest Florida …
Production increases are forecast for Israeli mandarins/tangerines, grapefruit and lemons in 2022–23 compared to the prior year, while orange production is projected to decline sharply. The forecast is from the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS). MANDARIN/TANGERINETotal mandarin and tangerine production in 2022–23 is forecast at 170,000 metric tons (MT), up from 159,000 MT the prior season. …
