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 …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has appointed internationally acclaimed entomologist and ecologist Matthew Thomas as director of the new Invasion Science Research Initiative (ISRI). Thomas will establish the framework for ISRI, which will bring together more than 120 UF/IFAS scientists from more than 20 departments currently dedicated to the detection, diversion, tracking and control …
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 …
Controlling fire ants in groves aids in the control of HLB-spreading Asian citrus psyllids (ACP), entomologist Lukasz Stelinski reported at the Citrus & Specialty Crop Expo. Fire ant control was just one way that Stelinski suggested for growers to manage ACP while reducing costs. The University of Florida Institute of Food and Agricultural Sciences entomologist said ACP populations drop when …
All commercial citrus producers in California are invited to apply for participation in the Citrus Research Board’s (CRB) California-focused Citrus Research and Field Trials (CA-CRaFT) project. The overarching goal of CA-CRaFT is to demonstrate the effects of additional mitigations on Asian citrus psyllid control within commercial citrus groves across the various citrus-growing regions in California. The project is supported by …
By Bryony C. Bonning and Lukasz L. Stelinski Asian citrus psyllids (ACP) transfer the pathogen that causes citrus greening from plant to plant as they feed. After confirmation of citrus greening in Florida in 2005, growers intensified their use of insecticides against ACP to try to stop disease spread. However, this method alone has yielded variable success and increased costs. …
The San Joaquin Valley ACP (Asian citrus psyllid)/HLB Area-Wide Task Force in California is recommending growers participate in a coordinated treatment application in commercial citrus orchards. This recommendation is for orchards located east and south of Bakersfield and includes young, non-bearing trees. The recommendation comes as a result of higher than normal HLB-spreading ACP finds in traps earlier this summer. …
An Asian citrus psyllid (ACP) sample confirmed positive for Candidatus Liberibacter asiaticus (CLas) — the bacteria that causes huanglongbing (HLB) — was collected from a commercial citrus grove in the Pauma Valley area of California’s San Diego County. This confirmation marks the first CLas-positive ACP found in a commercial grove in San Diego County and only the second grove detection …
Research studies show that about 60% of Florida citrus trees are infected by HLB disease within six months of planting. By one year, 100% of citrus trees are infected. For that reason, the use of individual protective covers (IPCs) has become very popular to protect young citrus trees from the Asian citrus psyllid (ACP). The covers have proven to be …
California’s commercial citrus groves remain free of HLB disease 14 years after Asian citrus psyllids (ACP) were first detected there. The state’s Citrus Pest and Disease Prevention Program (CPDPP) described that as “no small feat” in its recently released 2020-21 annual report. “The past fiscal year presented its fair share of headwinds for citrus-growing operations,” the report stated. “From pandemic-induced …
By Lauren Diepenbrock, Megan Dewdney, Fernando Alferez, Jawwad Qureshi and Ozgur Batuman Individual protective covers (IPCs) are becoming commonplace in citrus production to support the development of young trees after planting. IPCs are made of fine mesh and are intended to keep Asian citrus psyllids (ACP) off young plants. Because ACP can transmit the pathogen that causes citrus greening/huanglongbing, preventing …
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 …
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 …
Excelsior Aerospace Corporation announced it is pursuing funding from the U.S. Department of Agriculture (USDA) to build a free tool that can rapidly detect, track and manage huanglongbing (HLB) disease. “On one end, our tool would serve growers in states such as Texas and California to detect early symptoms of ACP (Asian citrus psyllid) and HLB infection and take measures …
In the latest episode of the All In For Citrus podcast, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Kirsten Pelz-Stelinski discussed her research on the Asian citrus psyllid (ACP) and a new grant from the National Institute of Food and Agriculture to further her work. The goal of the research is to use bacteria already present …
The Florida legislative session is well underway in Tallahassee. The University of Florida hosted its annual Gator Day at the Capitol in February to remind lawmakers of all that the school does for its students and stakeholders. Michael Rogers, director of the Citrus Research and Education Center, and fellow citrus team members from the University of Florida Institute of Food …
The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has revised the conditions for interstate movement of citrus fruit from areas quarantined for both sweet orange scab (Elsinöe australis, SOS) and citrus canker (Xanthomonas axonopodis, CC). The revisions allow for the movement of fruit to packinghouses located in contiguous states that are not quarantined for either disease. …
Individual protective covers (IPCs) on citrus trees have become a more common sight in Florida groves in recent years. The bags that cover young trees exclude the Asian citrus psyllid (ACP) from feeding on the plants, thus protecting them from HLB. Some estimates suggest that more than 1 million IPCs are now deployed in the state’s citrus groves. During the …
By Jawwad A. Qureshi and Azhar A. Khan The Asian citrus psyllid (ACP), Diaphorina citri, invaded Florida over two decades ago. The need to consistently suppress it became apparent soon after detection and particularly after discovering huanglongbing (HLB) disease, which it spreads. Managing HLB depends strongly on vector control to either reduce disease transmission of healthy trees or reinoculation. Single …
