(UF/IFAS) —The coronavirus has upended daily routines, events and schedules. From work to schools to shopping, every aspect of life changed overnight and continues to change with each passing day. Even with a global pandemic, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus researchers plow forward in their quest to find answers to fighting the devastating disease …
(UF/IFAS) — University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are working toward establishing a new biological method that may help growers control the insect that transmits the deadly greening disease into citrus trees. Greening is present in about 95 percent of the citrus trees in Florida, so by using a virus that may kill the insect, …
By Tripti Vashisth Constant supply and soil application of macronutrients and micronutrients can improve the health and productivity of HLB-affected citrus. A 20 to 50 percent higher than University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) recommended rate of micronutrients is beneficial for HLB-affected trees. However, the nutrition program should be customized for each grove, as no one …
(UF/IFAS) — When you meet Ajia Paolillo, you might think that everything old is new again. That’s because Paolillo, the new University of Florida Institute of Food and Agricultural Sciences Extension (UF/IFAS) citrus agent for DeSoto, Hardee and Manatee counties, leans heavily on the experience of faculty colleagues from previous experiences. “I learned so much working with Stephen Futch, Bill …
Cover crop research in Southwest Florida will include looking into the effectiveness of eco-mowing, or moving mowed clippings under the tree canopy rather than leaving clippings in row middles. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) soil microbiologist Sarah Strauss discusses numerous aspects of cover crop and compost research being conducted by her and other UF/IFAS scientists. …
By Nabil Killiny A dynamic research collaboration between several labs at Washington State University (Gang, Beyenal and Omsland labs), University of Arizona (Brown lab) and University of Florida (Killiny lab) recently reported an important step in the long-sought culture of the bacterium [Candidatus Liberibacter asiaticus (CLas)] associated with huanglongbing (HLB). The work, published in the journal Biofilm, describes a new …
Barbara Thompson worked approximately 37 years helping Citrus Research and Education Center (CREC) scientists publish manuscripts that aided growers and others in Florida’s citrus industry. For the last several years, she also took over the CREC reception area. She greeted visitors, answered phones and helped growers locate the proper researcher or other agency that could answer their questions. She retired …
By Ozgur Batuman and Amit Levy Management options for huanglongbing (HLB) are limited and rely heavily on insecticides for controlling Asian citrus psyllid (ACP) populations, even when integrated with other cultural control methods. Chemical strategies are expensive and, if not rotated, can contribute to the development of chemical resistance among ACP populations. In some cases, long-term chemical applications may have …
University of California, Riverside (UCR) professor Georgios Vidalakis recently provided an update on the state of California citrus for researchers in Florida. Vidalakis is a noted professor and Extension specialist in UCR’s Microbiology and Plant Pathology Department. Among other honors, he was recently named Presidential Researcher for Sustainable Citrus Clonal Protection. Vidalakis pointed out that California has benefited greatly from …
By Jawwad Qureshi Management of the Asian citrus psyllid (ACP) is needed in multiple environments, such as organic and conventional production systems and urban areas. However, the tools and approach may be different depending on the circumstances. Chemical control is the primary method used in commercial production to reduce psyllid populations, but the increased use of insecticides negatively affects the …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) will host a field day focused on improving citrus soil health, a topic of growing interest to researchers and growers. With the challenges of citrus greening, there is an increased need for understanding overall tree health, including the soil, Juanita Popenoe, UF/IFAS Extension multi-county agent, said. The field day …
At Citrus Expo in August, Rhuanito “Johnny” Ferrarezi reported on research into planting densities, irrigation and fertilization that might allow growers to better produce oranges in the Indian River area. He is a researcher with the University of Florida Institute of Food and Agricultural Sciences at the Indian River Research and Education Center in Fort Pierce. The Indian River region …
Like many farmers nationwide, citrus growers are looking for any edge in their fight against weeds, and they’d rather use fewer chemicals to control the plants, says a University of Florida scientist. That’s because chemicals can get into groundwater, surface water and plants themselves. Weed scientist Ramdas Kanissery and his colleagues at the University of Florida Institute of Food and …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) faculty members play the lead role in citrus research, but they depend heavily on graduate students to get the work done. Kelly Morgan, director of the UF/IFAS Southwest Florida Research and Education Center (SWFREC), explains the graduate students’ role in research, after first discussing new graduate student housing being constructed …
By Christopher Vincent Particle films can both increase tree growth and reduce Asian citrus psyllid populations. University of Florida (UF) research has found particle films delay infection with the CLas bacterium, which causes HLB. They also enhance growth rates and yield. Particle films do have limitations to efficacy, including being washed off in frequent or heavy rains. Overall, particle films …
The world’s peerless grapefruit grows in the Indian River Citrus District. Balanced with sugar and tart, and a thin rind for easy peeling, the fruit is sold mostly for export to European and Asian markets, where it is a high-price delicacy. But the once-thriving industry is in decline, and a plant pathogen is present in all of the state’s grapefruit …
Sept. 26 will be the official opening day for a new bio-safety citrus research facility at the University of California, Riverside (UCR). A ribbon-cutting ceremony and other activities are scheduled to highlight the day. Members of the California Citrus Research Foundation, California Citrus Mutual (CCM) and the Citrus Research Board will be in attendance. The facility was funded by California …
By Yu Wang, Charles Sims, Zhifeng Gao, Lisa House, Frederick Gmitter and Jude Grosser The citrus industry has faced significant declines in both production and consumption during the huanglongbing (HLB) era. For example, Florida orange production has dropped about 70 percent over the last two decades. In the absence of effective interventions, the spread of HLB will continue to reduce the …
Money provided by the Florida Legislature allows research into the positive impact of shade on trees, Bingo tree dieback and additional areas not funded by other sources. “The University of Florida (UF) each year gets legislative appropriations from the state, and these are Citrus Initiative legislative funds,” says Michael Rogers, director of the Citrus Research and Education Center (CREC). The …
By Karla Arboleda University of Florida Institute of Food and Agricultural Sciences researchers are getting ready to conduct several trials on tools used to protect young citrus trees from HLB. The team of five researchers will receive $665,471 in funding from the U.S. Department of Agriculture for experiments at the Citrus Research and Education Center (CREC) in Lake Alfred. Lauren …
