The September issue of Citrus Industry magazine centers on two topics: citrus under protective screen (CUPS) research and a wrap-up from the Citrus & Specialty Crop Expo. Three articles cover the latest CUPS findings from the University of Florida Institute of Food and Agricultural Sciences. An article by Arnold Schumann and his colleagues includes a summary of seven seasons of …
Federal and Alabama agriculture authorities recently established a citrus canker quarantine for all of Baldwin County, Alabama, to prevent the spread of the disease. The quarantine was established on July 25 by the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) and the Alabama Department of Agriculture and Industries (ADAI). On June 22, 2021, APHIS confirmed …
The sweltering heat being felt across the Southeast has done little to dampen the optimism shared by one citrus grower who believes this year’s crop is “very promising.” Kim Jones, who owns a citrus packing facility in Monticello, Florida, and is part-owner of a similar facility in Tifton, Georgia, discusses the state of this year’s crop in North Florida and …
A prolonged dry spell across the Southeast should have citrus growers ensuring their young trees are properly irrigated. But Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist, cautions growers about applying too much water. “The real young trees don’t have much of a root system, of course. It has been pretty dry. But you don’t want …
While sending citrus tissue samples to the lab for analysis remains important, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has developed a smartphone application (app) that can supplement lab analysis to identify leaf symptoms of key nutrient deficiencies and certain pests and diseases. Arnold Schumann, a professor of soil and water science with UF/IFAS, demonstrated how …
While many citrus growers use similar strategies to cope with HLB, no two approaches are exactly the same. One grower who uses a very different method to manage citrus greening is Chip Henry. In the May cover story of Citrus Industry magazine, he tells how growing organically has helped him successfully fight the disease. Sometimes, production practices aimed at protecting …
By Lauren Diepenbrock, Megan Dewdney, Christopher Vincent and Davie Kadyampakeni As the threat of potential shutdowns loomed in March 2020, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) team put the final plants in the ground, individual protective covers (IPCs) on trees, and kaolin and pesticide applications on a 2.7-acre planting at the Citrus Research and Education …
Alabama Cooperative Extension implores growers to be on the lookout for symptoms of citrus canker disease in their trees. Commercial growers need to scout their trees regularly to stop the disease’s potential spread, says Kassie Conner, Alabama Extension specialist. “What we need people to do right now is look for these symptoms and report it if they find it,” Conner …
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 …
By Emilie Demard and Jawwad Qureshi Managing the Asian citrus psyllid (ACP), a vector of huanglongbing (HLB), is critical for reducing disease incidence and improving tree health. Growing citrus under screened structures, referred to as citrus under protective screen (CUPS), protects trees from ACP and HLB. CUPS provides an opportunity to produce premium-quality fresh fruit by preventing psyllids and HLB …
By Jawwad Qureshi Managing the Asian citrus psyllid (ACP) is critical because of its role in spreading huanglongbing (HLB). Biological control is one method for ACP control. It is essential for developing integrated and sustainable pest management strategies. Biological control has always been a vital component of citrus pest management in Florida; understanding its contribution to the mortality of ACP …
By Xavier Martini and Danielle Sprague Cold-hardy citrus, that is, citrus grown above the 30th parallel north, is a blooming industry. In less than 10 years, the acreage in North Florida has gone from almost nonexistent to approximately 1,000 acres. Growers in the region plan to plant more in the coming years. In Georgia, there are approximately 2,000 acres across …
By Lukasz Stelinski The citrus leafminer (CLM) remains a major pest of citrus throughout Florida. The adults are small, white/silver-colored moths about half the size of a typical mosquito (Figure 1). Adults are difficult to spot due to their small size and because they are active only in the evening (dusk) and early pre-dawn hours. CLM adults can be monitored …
As the Georgia citrus industry continues to grow and prosper, growers should be aware of the potential signs of citrus pests and diseases that could be looming in their groves. Bill Barber, Certified Crop Advisor and owner of Barber Ag Services, delivered a presentation during the 2021 virtual Southeast Regional Fruit and Vegetable Conference. He addressed pests and diseases presently …
By Jawwad Qureshi Several studies have documented the positive effects of controlling the Asian citrus psyllid (ACP, Figure 1) for citrus tree health and sustainability in Florida. The mature blocks established before and after the discovery of huanglongbing (HLB) in 2005 continue to benefit from psyllid control. One psyllid is enough to infect a tree with HLB for life, and …
Now is the time of year for gifting fresh citrus to family and friends to enjoy. Unfortunately, people are not the only ones who enjoy eating citrus. Numerous pests can be found feasting on various plant parts in the grove. Keeping pests under control is the theme of the January issue of Citrus Industry magazine. Of course, the most concerning …
The use of chemicals for HLB-spreading Asian citrus psyllids (ACP) and other pests has raised several concerns, Jawwad Qureshi reported in a virtual Florida Citrus Growers Institute presentation. Those concerns include pest resistance, costs and diminishing biological control of pests, as well as concerns about health and the environment. Qureshi, a University of Florida Institute of Food and Agricultural Sciences …
By Lauren Diepenbrock While Asian citrus psyllids (ACP) are an ongoing concern in Florida citrus due to their role in spreading the bacterium associated with citrus greening, they are not the only pest of concern to growers. Citrus leafminer (CLM) and root weevils are two pests that have been raising concerns and adding to the challenge of managing productive citrus …
It’s no secret that the most damaging pest in Florida citrus is the Asian citrus psyllid. But there are other bugs growers need to watch out for, too. The January issue of Citrus Industry magazine takes a look at current pests of concern and offers management methods. An article on HLB reduction strategies focuses on tools growers can use to …
By Arnold Schumann, Laura Waldo, William Holmes, Gary Test and Tim Ebert Artificial intelligence (AI) is increasingly common in electronic devices at home or work, in social media, video streaming services, electronic commerce, and in internet search engines. Now, AI is rapidly entering the farming scene. Growers using modern precision agriculture tools and techniques often face a barrage of high …
