Jim Rogers All In For Citrus Podcast, CUPS, HLB Management

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 …

Let’s Talk About CUPS

Jim Rogers CUPS, Economics, Florida Department of Citrus

By Thomas H. Spreen Citrus under protective screen (CUPS) is a relatively new technology being adopted to help spur expansion of fresh citrus production in Florida. Large screen houses (approximately 10 acres) are constructed. In the current arrangement, several screen houses are located together to facilitate caretaking and harvest. Trees are planted at high densities (more than 300 trees per …

Improving Color Break and Brix in CUPS

Jim Rogers CUPS, Production, Research

Arnold Schumann recently reported on what he called “the most successful and practical intervention for improving color break and quality in CUPS fresh fruit.” CUPS stands for citrus under protective screen, a growing technique that Schumann, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher, helped pioneer in Florida. He reported on his work at a Feb. …

Scout for Problems, Even in CUPS

Ernie Neff CUPS, Pests

Growers should monitor for pests and diseases, even in the citrus under protective screen (CUPS) systems designed to keep HLB-spreading psyllids out of trees, according to entomologist Jawwad Qureshi. He told more than 25 people participating in a Dec. 1 virtual seminar that CUPS “are not foolproof systems,” and said citrus can’t be grown successfully without pest management. Qureshi works …

CUPS Not for All Citrus Growers

Tacy Callies CUPS

One of the unique ways of managing citrus greening disease developed by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers is not for all producers. Citrus under protective screen (CUPS) is just too expensive for all growers to take advantage of, says Fred Gmitter, a UF/IFAS citrus breeder. “It’s an extremely expensive investment,” Gmitter says. “For that …

CUPS Pest Management Pointers

Ernie Neff CUPS, Pests

Citrus under protective screen (CUPS) systems in Florida provide trees significant protection from the Asian citrus psyllid (ACP) and the HLB it spreads. Several other pests are also significantly reduced in CUPS, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers reported. For instance, citrus leafminer (CLM) populations were reduced by more than 80%. Large predators such as …

CUPS Yielding Positive Results for Grapefruit

Tacy Callies CUPS

An innovative way to manage huanglongbing (HLB) disease is producing impressive results in University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research. According to Arnold Schumann, UF/IFAS professor at the Citrus Research and Education Center (CREC), citrus under protective screen (CUPS) production systems have increased yields with zero effect from HLB. He shared research results during a recent …

Chilli Thrips a Potential Problem in CUPS

Tacy Callies All In For Citrus Podcast, CUPS, Pests

A modified way of producing citrus in Florida to protect against the Asian citrus psyllid may provide shelter for another pest — chilli thrips. Citrus under protective screen (CUPS) production systems protect against the psyllid and the huanglongbing (HLB) disease the pest transmits. However, according to University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lauren Diepenbrock, the …

Brothers Jerry and Keith Mixon have been surprised by how well trees grow in their citrus under protective screen (CUPS) facilities in Alturas, Florida. “All of the varieties we are growing have responded amazingly,” they said recently about their CUPS experience. Though each brother has his own CUPS structures, they jointly discussed their results. The brothers have a combined 130 …

Psyllid Exclusion and Screen Selection

Tacy Callies CUPS, Tip of the Week

By Arnold Schumann and Timothy Ebert As the adage goes, “necessity is the mother of invention.” Since the presence of huanglongbing (citrus greening) in Florida, new methods of managing the Asian citrus psyllid that transmits the bacteria have resulted in the growing of citrus in screen houses (CUPS, citrus under protective screen) and the use of individual protective covers (IPCs), …

Techniques for Improving CUPS-Grown Fruit

Ashley Robinson CUPS, Research

For a citrus under protective screen (CUPS) production system to be profitable, the cost of the system must be offset by high yields of premium-quality fresh fruit with strong market prices. Researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) have expanded their CUPS research trials to investigate management strategies that improve fruit quality and yield. …

Managing Pests in a CUPS System

Ashley Robinson CUPS

Citrus under protective screen (CUPS) does a great job of safeguarding trees from the HLB-spreading Asian citrus psyllids. However, CUPS does not protect trees from all other pests. The benefits of eliminating HLB are immediate and include rapid, normal tree growth, higher yields of premium-quality fruit and less fruit drop. Since CUPS is a relatively new system, researchers are still …

Pests in CUPS and IPCs

Ernie Neff CUPS, Pests

Citrus under protective screen (CUPS) and young trees covered with individual protective covers (IPCs) have generally been well protected from HLB-spreading Asian citrus psyllids, but not from all other pests. Entomologist Jawwad Qureshi says the psyllids only get to trees when a CUPS structure or IPC is damaged, as happened to CUPS during Hurricane Irma in 2017. “Otherwise they do …

CUPS: Managing Small Fruit Size
