By Christopher Vincent, Megan Dewdney and Liliana Cano Bingo mandarin hybrid is a variety with many promising characteristics, but it brings specific challenges to profitable production. One challenge identified early in the push to plant Bingo was stem dieback that led to tree loss. After looking into this problem for the past four years, University of Florida Institute of Food …
By Megan Dewdney Editor’s note: This article originally stated that citrus black spot was in Hardee County. It should have said Hendry County, and has now been corrected. Citrus growers in Florida continue to battle new pests and diseases. They have been learning to manage citrus black spot for the last 12 years. The disease is still localized mainly in …
University scientists, engineers, producers, government agencies and industry officials across the Southeast recently met to brainstorm ways to use artificial intelligence (AI) to help growers. They concluded that they could empower growers and equip farms to increase their economic and environmental sustainability and develop resilient solutions to address climate change by using AI. The three-day conference, Envisioning 2050 in the …
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 …
The state legislative session was among the topics discussed at the March 21 Florida Agricultural Policy Outlook Conference. The annual event was held at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Mid-Florida Research and Education Center in Apopka. More than 100 people attended the conference, either in-person or virtually. John Walt Boatright, director of national affairs …
The Australian finger lime has created a buzz among chefs and mixologists for its caviar-like texture and flavorful pulp. The fruit also has captured interest among growers for its seemingly high tolerance to HLB. On March 23, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a half-day online symposium on finger limes to provide growers with …
By Fernando Alferez, Ute Albrecht, Susmita Gaire, Ozgur Batuman, Jawwad Qureshi and Mongi Zekri University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers established a field trial in February 2018 to evaluate the efficacy of individual protective covers (IPCs) to prevent Asian citrus psyllids from spreading HLB and to study the effects on tree growth and physiology. The …
Nabil Killiny, an associate professor of plant pathology for the University of Florida Institute of Food and Agricultural Sciences, has been studying the relationship between the bacterium that causes HLB (Candidatus Liberibacter asiaticus) and its vector the Asian citrus psyllid (ACP). Globally, insect-borne vector pathogens are responsible for more than 700 plant diseases. HLB ranks high among those in terms …
The size of fruit that should be sprayed, the spraying interval and ways to avoid copper phytotoxicity were among the citrus canker topics plant pathologist Megan Dewdney offered growers recently. Dewdney said fruit are most susceptible to canker when they are between 3/8 inch and 1.5 inches in diameter. The fruit rind becomes much more resistant when the fruit is …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has committed to updating nutrition recommendations for citrus now that HLB is endemic across the state. Some of this ongoing research was discussed during the February All In For Citrus podcast. Growers will be interested to hear from Davie Kadyampakeni, a UF/IFAS assistant professor of soil and water science, …
In late February, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted its second annual Flavor Summit. The hybrid in-person/online event was held at the Citrus Research and Education Center (CREC) in Lake Alfred. CREC and the UF Center for Smell and Taste hosted the event that took a deep dive into the science of how flavors …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP It’s not unusual for the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) to have a dozen contacts with Peter Chaires in a day, between the emails, calls and visits. Chaires serves as executive director of the New Varieties Development & Management Corp. (NVDMC), executive vice president of Florida Citrus Packers and …
Recent research describes in detail how HLB causes damage to citrus trees and presents the case that HLB is a pathogen-triggered immune disease. A pathogen-triggered immune disease results from the activation of an organism’s immune cells fighting a pathogen. Nian Wang, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor, took part in the research. This is the …
Emilie Demard is working to control mites and other pests that damage fresh grapefruit growing as citrus under protective screens (CUPS) at the Indian River Research and Education Center in Fort Pierce. “I look at biological control — in this case, predatory mites controlling pest mites to minimize the need for agrochemicals,” said Demard, a Ph.D. entomology graduate with the …
In the latest episode of the All In For Citrus podcast, Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, previews two upcoming events citrus growers will want to attend. The first is a Finger Lime Symposium. The half-day event will be held virtually from 1 p.m. to 5 …
The horticultural characteristics of new citrus varieties are important, especially in the era of HLB when disease tolerance is critical. But how the fruit tastes and other consumer attributes are equally important. That’s why citrus variety display days are vital in citrus breeding. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in …
Fire ant management is essential to the long-term sustainability of citrus groves. This is particularly true for young trees still trying to develop root systems, said Xavier Martini, assistant professor of entomology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center (NFREC). Martini spoke on insect management at the recent UF/IFAS …
By Brett Bultemeier and Lauren Diepenbrock The revocation of chlorpyrifos residues and tolerances that became effective on Feb. 28, 2022, caused some confusion and concern when it was first announced. The legal description provided by the Environmental Protection Agency is challenging to fully understand. Therefore, the Pesticide Information Office from the University of Florida Institute of Food and Agricultural Sciences …
A La Niña weather pattern is most likely this spring, with higher-than-average temperatures and below-average rain predicted in Florida, researcher Megan Dewdney reported in a Feb. 24 presentation about postbloom fruit drop (PFD). That could have some influence on the severity of PFD, since its preferred climate is humid and subtropical, and the fungus moves with rain splash and wind-borne …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers emphasized the importance of efficient irrigation and nutrient management at a workshop earlier this month at the Citrus Research and Education Center in Lake Alfred. In Florida, the citrus industry accounts for about 30% of irrigated cropland acreage, reported UF/IFAS researcher Alisheikh Atta. Worldwide, the agriculture industry consumes about …
