Pest Incidence and Management in CUPS
By Jawwad A. Qureshi and Salman Al-Shami The citrus under protective screen (CUPS, Figure 1) system is designed so citrus can grow inside screened enclosures to protect it from huanglongbing (HLB) and the Asian citrus psyllid (ACP, Diaphorina citri). ACP is the primary vector of the pathogen responsible for causing HLB, known as citrus greening disease. This vector-pathogen combination is …
CUPS Grower: ‘It Is a Calculated Risk’
Although it was National OJ Day, the Southwest Florida Small Farmers Network held its spring meeting May 4 at a Polk County facility growing citrus for the fresh market. The Story Companies and Dundee Citrus Growers Association (CGA) conducted a tour of Story’s 11-acre citrus under protective screen (CUPS) pod. The Story pod is one of numerous such pods at …
Grower and Researcher CUPS Collaboration
The spread of HLB in Florida citrus groves has forced growers and researchers to try all sorts of practices to fight off the disease’s devastating effects. One of the most successful methods has been planting citrus under protective screen (CUPS). The screen excludes the Asian citrus psyllid (ACP) and keeps HLB out of plantings. CUPS also is a great example …
Don’t Forget Citrus Black Spot in Florida
While HLB tops the agenda, Megan Dewdney, an associate professor of plant pathology and an Extension specialist with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), reminded growers that citrus black spot (CBS) remains a concern. This was the topic of a presentation she made during the Florida Citrus Growers’ Institute held in Avon Park in April. …
Hunt Bros. Packinghouse Closing
The Hunt Bros. citrus packinghouse in Lake Wales will close for good at the end of this season, primarily due to the impacts of Hurricane Irma on company groves in 2017. The family-owned packinghouse opened in 1928. Frank Hunt III, an owner, discussed the closing in an April 22 letter to employees: “It was certainly our desire to keep it …
Drone Aids Brazil in HLB Battle
The use of a drone for chemical control of the psyllid that spreads HLB adds to Brazil’s efforts to battle the citrus disease, recent research indicates. The research was conducted by Fundecitrus in partnership with the startup Anáhata Serviços Agronômicos. Drones are ideal for complementing terrestrial applications and for emergency applications that need to be made quickly. For example, a …
U.S. Orange Juice Output to Hit 50-Year Low
Total U.S. orange juice (OJ) production in the current 2021–22 season is forecast at 286 million single-strength equivalent (SSE) gallons, the U.S. Department of Agriculture’s Economic Research Service reported recently. If realized, this volume will be the lowest in more than 50 years. To compensate for lower production, U.S. OJ imports are expected to increase over last year, reaching more …
Further Cuts to Florida Citrus Forecast
On March 9, the U.S. Department of Agriculture’s National Agricultural Statistics Service (NASS) reduced Florida’s orange and grapefruit crop forecasts again. Valencia oranges took the biggest hit, dropping 3 million boxes, or 12%, to 23 million boxes. The forecast for the non-Valencia crop, which is virtually all harvested, actually rose 500,000 boxes, or 4%, to 18.2 million boxes. That means …
Which Rootstock to Select
Valencia trees on high-vigor (left) and low-vigor (right) inducing rootstocks in a Central Ridge field trial. Note the higher yield efficiency of the smaller trees on the right and the leaning of these trees due to Hurricane Irma. By Ute Albrecht Rootstock selection is critical for longevity and productivity of a grove. The decision should be based on compatibility with …
U.S. Citrus Processing Report
In 2020-21, 57% of U.S. citrus was used for processing, and most of the processed fruit was oranges, the U.S. Department of Agriculture’s Economic Research Service reported in September. Florida produced 81% of all U.S. oranges for processing, while California and Texas produced the remainder. Florida and Texas had smaller orange crops for the processed market in 2020-21 compared with …
Black Spot Management Strategies Updated
The title of Megan Dewdney’s Citrus Expo presentation was, “Shorten the skirts? Whether skirting improves citrus black spot fungicidal management.” The answer was “no,” based on trials she conducted to make that determination. But while skirting doesn’t appear to improve citrus black spot (CBS) fungicide programs, she pointed out that “there are other good disease management reasons to skirt.” Dewdney …
Lessons on Yield and Root Health From Modified Nutrition
By Davie Kadyampakeni, Evan Johnson, Kelly Morgan and Ali Atta Citrus production in Florida has been decreasing over the last 15 years due to several factors, with huanglongbing (HLB) a major driver. This disease has severe effects on citrus growth and production, including stunted vegetative growth, misshapen small fruits and poor color development, root mortality, stunted branches, excessive fruit drop, …

OLDER, LESS PRODUCTIVE TREESSpreen, University of Florida Institute of Food and Agricultural Sciences professor emeritus, cited an older tree inventory and declining fruit per tree as contributors to projected yield declines. He said …
Maximizing Rootstock Seed Production
By Fernando Alferez, Deived Uilian de Carvalho, Daniel Boakye, Tim Gast and Manjul Dutt Endemic HLB in Florida has provoked increased pressure to replant and reset infected groves. This has resulted in concern from citrus growers and nursery operators about seed availability for the most popular rootstocks in the state. In the past, all rootstock fruit (both early and late …
Florida Citrus Industry Continues Decline
Florida citrus production has decreased for almost two decades. According to Marisa Zansler, director of economic and market research at the Florida Department of Citrus, the two main factors for the state’s steady decline are citrus greening (huanglongbing, known as HLB) and Hurricane Irma. Zansler presented staggering statistics during the Florida Agricultural Policy Outlook Conference on Feb. 26 that showed …
