The success of citrus under protective screen (CUPS) in protecting Florida citrus from citrus greening, also known as huanglongbing or HLB, was not surprising to Arnold Schumann. The professor of soil fertility and water quality at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center is thankful research had yielded a temporary solution …
A Nov. 22 Lake County farm tour, hosted by University of Florida Institute of Food and Agricultural Sciences Extension, included a visit to the 13-acre citrus under protective screen (CUPS) site owned by IMG Citrus. Located in Groveland, the facility consists of Ruby Red grapefruit on Swingle rootstock planted in May 2022. Clint Updike, IMG citrus production manager, told farm …
The benefits of implementing citrus under protective screen (CUPS) could be major for growers in the cold-hardy region. But they first must overcome the major limiting factor associated with the system — its cost. Arnold Schumann, a professor of soil fertility and water quality at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education …
The U.S. Department of Agriculture National Institute of Food and Agriculture (USDA/NIFA) has invested more than $250 million to find a solution for HLB. One example of USDA NIFA-funded research is citrus under protective screen (CUPS). University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) scientist Arnold Schumann and colleagues began testing CUPS at the Citrus Research and Education Center …
Chilli thrips (Scirtothrips dorsalis) has been documented in Florida since 1991. This pest has a history of impacting ornamentals, some vegetables, grapes and berry crops. Most recently, chilli thrips has affected citrus, but only in nurseries and in citrus under protective screens (CUPS). Feeding damage includes death of young flush (Figure 1), leaf damage on expanded flush that results in …
By Ariel Singerman and Arnold W. Schumann To exclude the Asian citrus psyllid (ACP, Diaphorina citri) vector of huanglongbing (HLB) and thereby produce disease-free healthy fruit, fresh citrus can be grown under protective screen structures. The expected economic benefit from adopting citrus under protective screen (CUPS) and excluding the ACP is increased yield and quality of fruit, which in turn, are …
Positive results from experiments with photoselective shadecloth for color break and with plant growth-promoting bacteria for tree health were reported at a June 14 citrus under protective screen (CUPS) seminar. Presenter Arnold Schumann also gave an update on the generous fruit yields being generated in CUPS. Schumann is a University of Florida Institute of Food and Agricultural Sciences Citrus Research …
Arnold Schumann, a professor of soil fertility and water quality with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), led the effort to study the effectiveness of citrus under protective screen (CUPS) in protecting trees from HLB. The work resulted in growers having confidence in the practice. Today, Florida CUPS plantings are closing in on 1,000 commercial …
Mixon family members were pioneers in the Florida blueberry industry. Brothers Jerry and Keith Mixon planted their first berries in 1993. Over the years, they grew their business and became worldwide marketers, eventually adding blackberries, raspberries and strawberries to their portfolio. BACK TO CITRUSIn 2011, they sold their berry business to the Dole Food Company. But the brothers still had …
Some growers are taking a closer look at citrus under protective screen (CUPS), while others have already adopted the production system. CUPS has been proven to protect trees from HLB and hurricane damage. The May issue of Citrus Industry magazine features grower brothers who are early adopters of CUPS. Jerry and Keith Mixon have 150 acres of CUPS production in …
By Rhuanito S. Ferrarezi and Mark A. Ritenour Citrus under protective screen (CUPS) is a modern production system that excludes the Asian citrus psyllid and, consequently, the devastating disease citrus greening (huanglongbing or HLB) from plants cultivated in screenhouses. A recent study investigated the effect of different irrigation management strategies on fruit yield and quality of grapefruit grown in CUPS. …
Foliar sprays of insecticides timed to citrus flushing provided a significant reduction in Asian citrus psyllid (ACP) populations compared to standard grower practices, researcher Jawwad Qureshi reported. Timing sprays to flushing also led to a reduction in sprays, the University of Florida Institute of Food and Agricultural Sciences associate professor of entomology said in a virtual presentation on Feb. 22. …
By Rhuanito S. Ferrarezi and Mark A. Ritenour Two independent trials were conducted under a commercial citrus under protective screen (CUPS) system. The first trial was to investigate canopy management strategies to improve fruit yield and quality of mandarins. Canopy management is essential for CUPS since the environment stimulates vigorous vegetative growth, posing operational challenges to mechanization that can be …
High yields of HLB-free fruit can hypothetically be sustainably produced in citrus under protective screen (CUPS), Arnold Schumann said at a Dec. 14 field day at the Citrus Research and Education Center (CREC). He backed that up with data showing high yields from Ray Ruby grapefruit planted at high densities and fertigated in CUPS. Trees in his CUPS facility are …
In the search for ways to survive citrus greening, some growers have chosen the citrus under protective screen (CUPS) system as their solution. While CUPS can be costly to construct, it has proven to effectively prevent the deadly disease. But some have asked if the structures would hold up in extreme weather and adequately protect the trees. Hurricane Ian helped …
By Emilie Demard Mites are pests of economic importance in traditional groves and citrus under protective screen (CUPS). Results from a two-year survey in CUPS at the Indian River Research and Education Center (IRREC) in Fort Pierce, Florida, showed that the citrus rust mite and the citrus red mite populations can reach high levels resulting in leaf and fruit damage. …
The focus of citrus breeding at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) differs for fruit produced for the juice market vs. fruit for the fresh market. Citrus breeder Jude Grosser, a UF/IFAS professor of plant cell genetics, spoke during the Cold-Hardy Citrus Field Day at the North Florida Research and Education Center in Quincy on …
By Arnold Schumann, Laura Waldo, Chris Oswalt, Napoleon Mariner, Timothy Ebert, Perseveranca Mungofa, Shankar Shrestha and Laura Cano-Castro Florida grapefruit production for the 2021–22 season was 92% less than in 2003–04, which was prior to the arrival of huanglongbing (HLB) disease [Source: U.S. Department of Agriculture National Agricultural Statistics Service, (USDA NASS)]. The decrease in Florida tangerine production for the …
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 …
By Fernando Alferez, Daniel Boakye, Susmita Gaire and Tim Gast Growing citrus under protective screen (CUPS) structures for fresh fruit production is effective in controlling HLB disease by completely excluding the Asian citrus psyllid (ACP, Diaphorina citri). After several years of research on CUPS to grow HLB-free trees in Florida, and with commercial growers increasingly adopting this technology, there is …
