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 …
By Tripti Vashisth, Garima Singh and Megan Dewdney Citrus trees grown in the field undergo various types and levels of stress continuously. The stressors can be several things, including heat, cold, drought, soil pH, chemicals, pests and diseases. The constant presence of huanglongbing (HLB) and psyllid infestation adds stress to the trees, which compromises the plant response and makes the …
The Citrus Research and Field Trial (CRAFT) Foundation Board held its initial meeting on July 31 at Florida Citrus Mutual (FCM) headquarters in Bartow. FCM President Tom Mitchell as well as FCM board members Glenn Beck and Mark Wheeler serve on the CRAFT board along with Harold Browning, Premier Citrus; John Updike Jr., Florida citrus grower; Phillip Rucks, Phillip Rucks …
Since 2016, federal authorities have allowed Florida citrus growers to spray oxytetracycline solutions on their trees to combat citrus greening disease. A newly published University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) study suggests that the bactericide would be more effective if it were injected into citrus tree trunks, a practice not currently approved under U.S. law. Citrus …
By Ariel Singerman This article summarizes the major changes in the cost of production for processed oranges in Florida since the outbreak of huanglongbing (HLB). To deal with the disease, growers have significantly changed their cultural practices. Those changes have had a considerable impact on the cost of production per acre. NOMINAL COSTS VS. REAL COSTSHowever, given that inflation also …
A new study suggesting a link between sugary drink consumption, including 100% fruit juice, and increased cancer risk was recently published in a medical journal. The study has spurred a series of news media stories. Researchers of the study, who are based in France, assessed the associations between the consumption of sugary drinks (sugar sweetened beverages and 100% fruit juices), …
Amid ongoing struggles in Florida’s citrus industry, the Florida Department of Citrus appears to be turning attention to studying orange juice consumption. The department said Tuesday it is looking for three separate studies that would assess various aspects of orange juice consumption, including how it can affect people’s moods when drinking it as a snack. According to a bid notice, …
By Tripti Vashisth, Lisa Tang and Sukhdeep Singh In citrus, huanglongbing (HLB) causes an increase in the mature fruit drop rate up to three months prior to commercial harvest. This preharvest fruit drop results in a great reduction in yield and overall grove productivity. Since the plant growth regulators that improve fruit retention on healthy trees do not have consistent …
Southwest Florida Research and Education Center (SWFREC) Director Kelly Morgan provides an update on citrus research being conducted at the center. SWFREC is operated by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Morgan says most of the research is “related to greening, but not all of it.” Greening is another term for huanglongbing (HLB), the citrus …
Researchers with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are already trying to help growers figure out how to effectively manage the problems created by an invasive pest – confirmed last week in Highlands County — that could further erode citrus production at a time when growers are just beginning to turn the corner on managing …
By Ramdas Kanissery, Steve Futch, Brent Sellers and Camille McAvoy Glyphosate is a popular post-emergent herbicide among Florida citrus growers for its broad-spectrum of weed control under trees and in row middles. The use of glyphosate as a “burn-down” application alone, or in combination with other herbicides, is a standard practice in citrus groves. Various glyphosate-containing product formulations are available …
While citrus growers continue to look for best management approaches to deal with the deadly greening disease, scientists will take an integrated look at how to protect young trees by using existing tools growers can use. Five scientists from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) will compare insect management tools, including insect-proof netting. Researchers also …
After serving nearly 10 years as the senior vice president for agriculture and natural resources with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), Jack Payne announced he will retire next year. His last day with UF/IFAS will be July 1, 2020. Payne has overseen Extension offices across Florida and its 12 research and education centers since …
By Fernando Alferez, Christopher Vincent and Tripti Vashisth Brassinosteroids (BR), a relatively newly discovered class of plant hormone, regulate several developmental and physiological processes in fruit crops such as grapes, pears and cherries and in some non-edible plants. BR also induce disease resistance against different pathogens in a great number of crop plants. A form of BR (epibrassinolide) was shown …
