By Tripti Vashisth and Mary Sutton Prolonged water deficits can negatively impact flowering, fruit growth, crop load and fruit quality. Unfortunately, HLB-affected trees are more susceptible to water deficits than healthy trees due to extensive root loss. Observing HLB-affected trees throughout the dry season showed that severely symptomatic trees consistently had lower leaf water potential than mildly symptomatic trees. This …
Fundecitrus has launched Evaluate Psyllid, a tool that will help citrus growers choose insecticides to manage the pest that spreads citrus greening disease. Evaluate Psyllid will make available the results of insecticide efficacy experiments on field psyllid populations in different regions of Brazil’s citrus belt. The insecticide efficacy data will be constantly updated as experiments are carried out. It will …
Bill Lennon is working with researchers to learn more about survivor trees that are standing up to HLB. Bill Lennon is a fifth-generation citrus grower who can recall the industry’s glory days when Central Florida had hundreds of thousands of citrus acres before the 1980s freezes pushed production southward in the state. But he’s remained dedicated to the area, managing …
Florida Southern College (FSC) in Lakeland will offer a new horticulture, land and resource management major in August for incoming students and current students who want to add a major or switch majors. It consists of 28 credit hours (without general education courses). Sixteen of those hours come from horticulture science, and the rest are business oriented with a focus …
Tangerine production in 2023–24 in Türkiye (previously known as Turkey) is forecast to increase 55% to 2.88 million metric tons (MMT), according to the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS). The huge increase is due to favorable spring rains and temperature conditions during blossoming in March 2023. The yield in Türkiye’s Aegean region is expected to increase …
Federal and Texas agriculture officials announced they are establishing four new quarantine areas for citrus canker in Brazoria and Harris counties, Texas. They are also expanding three existing quarantine areas for citrus canker in Brazoria, Fort Bend, Galveston and Harris counties. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) and the Texas Department of Agriculture …
By Brenda Eubanks Burnette In his book, “The Cultivation of Citrus Fruits,” first published in 1926 by The MacMillan Company, H. Harold Hume covers a variety of topics, including the use of fertilizers and the different needs of young trees versus bearing trees. Following are insightful excerpts: “Young adult trees differ in their fertilizer requirements. Young trees use their food …
Total U.S. citrus production levels are projected to continue their long-term decline before stabilizing through 2033, the U.S. Department of Agriculture’s (USDA) Office of the Chief Economist recently reported. The trend is attributed to declining orange and grapefruit production alongside increasing production of lemons and tangerines. In the report, USDA Agricultural Projections to 2033, total U.S. citrus production is projected …
By Clara Diekman, Taylor O’Bannon and Michelle Danyluk Many citrus packers already rely on product lot codes to aid in the traceability of their product in the case of a contamination event. These product lots can be determined in a variety of ways, including the date of harvest, field, harvest crew, etc. Regardless of the method used to assign lot …
Using the plant growth regulators (PGRs) cytokinin in spring, gibberellic acid (GA) in summer and 2,4-D in late fall can be helpful for HLB-affected trees, horticulturist Tripti Vashisth reported. Her PGR update came during a Feb. 21 OJ Break. Multi-county citrus Extension agent Chris Oswalt hosted the event at the University of Florida Institute of Food and Agricultural Sciences Citrus …
Global lemon/lime production in 2023–24 is forecast up 225,000 tons from the prior year to 10 million tons, the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) reported. Higher production in the European Union, South Africa and Turkey more than offsets lower production in Mexico and the United States. Here are the regional lemon/lime forecasts for 2023–24: Turkey production …
Georgia’s citrus industry started with the help of University of Georgia (UGA) Extension. Research assistance from UGA could help the industry flourish. Georgia citrus growers will have an opportunity to vote on a marketing order that will help fund potential research, explains Ken Corbett, chairman of the Georgia Agricultural Commodity Commission for Citrus Fruits and a producer at Corbett Brothers …
Studies with psyllid pheromones show that the insect’s behavior is altered when it is infected by the HLB-causing bacterium Candidatus Liberibacter (CLas). This makes it difficult to produce a commercial psyllid-control product based on the insect pheromone, Brazil’s Fundecitrus has concluded. “The sexual pheromone is an attractant produced by the female of the species, which promotes behavioral changes in male …
Growers have largely adopted new trunk-injection therapies to fight the effects of HLB in citrus groves. In addition, plant growth regulators have helped improve tree health and fruit retention. One University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) scientist reminds growers to maintain their fertilizer programs as the new therapies are deployed. Davie Kadyampakeni, UF/IFAS associate professor of …
By Brett Bultemeier, Mike Aerts and Lauren Diepenbrock On Dec. 28, 2023, the U.S. Court of Appeals for the Eighth Circuit revoked a previous decision related to chlorpyrifos tolerances for food. Chlorpyrifos is a broad-spectrum insecticide used in a variety of crops, including citrus. The original decision revoked all food tolerances, whereas this new ruling essentially reinstates them. This means …
By Marisa L. Zansler The landscape of the Florida citrus industry has undergone significant transformations throughout its history. Over the past decade, it has faced substantial challenges in both supply and demand. Florida orange juice (OJ) production dropped by 85%, from 615 million gallons in the 2013–14 season to an estimated 94 million gallons in 2023–24. Even as imports increased …
Global grapefruit production in 2023–24 is estimated up slightly from the prior year to 6.9 million tons, the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) reported. A slight increase in China more than offset lower production in South Africa. World exports of grapefruit are projected to increase while fruit for processing is forecast to be lower. Here are …
In the face of HLB in Florida, a recent study delved into the economic viability of incorporating cover crops in citrus groves to enhance soil health and overall tree well-being. Shourish Chakravarty and Tara Wade wrote an article, Cost Analysis of Using Cover Crops in Citrus Production, about the study. Both authors are with the University of Florida Institute of …
Conditions for the movement of fresh citrus fruit from the Redlands Oriental fruit fly (OFF) quarantine area of San Bernardino and Riverside counties in California have been temporarily modified for the duration of the 2024 harvest season. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) announced the modification on Feb. 5. Due to the imminent …
South African orange and orange juice (OJ) production are both forecast to decline slightly in 2023–24 compared to the prior season, according to the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA FAS). FRESH ORANGES Orange production in South Africa is forecast at 1.62 million metric tons (MMT). That’s a decrease of 1% from the prior season based on a …
