A Citrus Expo presentation about best management practices (BMPs) focused on what growers should be doing now in their irrigation and nutrient management programs. The presentation noted that current BMPs were developed prior to HLB’s discovery in Florida in 2005, and that studies are underway to revise the citrus BMPs for nitrogen and phosphorus. The presentation was created by University …
The Asian citrus psyllid (ACP) is not yet well established in Georgia. University of Georgia (UGA) assistant professor and small fruits pathologist Jonathan Oliver wants to keep it that way. The ACP vectors citrus greening disease (HLB), which has decimated Florida’s citrus production. Oliver encourages producers to scout their groves regularly to avoid a similar fate happening in Georgia. “It’s …
Andra Johnson, associate director of Penn State Extension, will be the next dean of University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension and director of the Florida Cooperative Extension Service. He will assume the role on Nov. 1. Johnson will lead UF/IFAS’ statewide network of more than 650 faculty educators and scientists, whose programs support economic, environmental …
Fundecitrus and its cooperators announced on Sept. 10 that Brazil’s 2021-22 orange crop forecast has decreased to 267.87 million boxes. This is a decrease of 8.9% from May’s initial forecast of 294.17 million boxes. While Brazil was initially expecting a larger orange crop this season, the updated forecast is less than the 268.63 million boxes Brazil produced in 2020-2021. The …
The next key to winning the battle against citrus diseases such as citrus canker may be in the tiniest microbes that live inside the citrus tree. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers hope to discover how these microbes may benefit citrus trees in their natural fight against diseases. The end result may be an environmentally …
By Evan G. Johnson It is time to start thinking about protecting the fall root flush that will start soon and continue through November/December. This is the largest root flush of the year that stores carbohydrate reserves for next spring. Coming out of the rainy season, phytophthora has had the chance to build up plenty of inoculum, especially in groves …
The Florida Citrus Commission (FCC) recently heard presentations about the history and current work of both the New Varieties Development and Management Corporation (NVDMC) and the Citrus Research and Development Foundation (CRDF). NVDMCRosa Walsh, Florida Department of Citrus (FDOC) director of scientific research, said from 2003 to 2005, the FCC discussed the need for a program that would develop, license …
Five Citrus Research and Field Trial (CRAFT) Technical Working Group leaders on Aug. 31 discussed the types of projects they’d like to see CRAFT Cycle III growers pursue. The types of projects the leaders expressed interest in will, to some extent, fill gaps in knowledge expected to be gained from previous cycles. CRAFT pays Florida growers to plant trees on …
By Yiannis Ampatzidis and Ute Albrecht Nutrient management is important for citrus production. Regular nutrient assessments should be conducted to optimize nutrient balance and prevent deficiencies or over-fertilization. Optimizing nutrition is important for tree health and can improve tolerance to stresses and diseases. Good nutrient management requires regular field monitoring to identify problems and examine crop responses. Leaves need to …
A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher recently determined how bacterium causes the devastating citrus disease HLB. Information about further research into ways the discovery can help growers reverse the effects of HLB and improve tree health will be presented this fall. MORE DETAILS TO COMEUF/IFAS Citrus Research and Education Center (CREC) Director Michael …
The economic trends of Florida’s citrus industry and how the impacts of a natural disaster are determined were discussed recently by a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) economist. Christa Court, assistant professor of regional economics and director of the UF/IFAS Economic Impact Analysis Program, said Florida citrus production and yield are trending downward. “But we …
Editor’s Note: Tripti Vashisth with share new information on the use of gibberellic acid treatments to improve health and yield of HLB-diseased trees in a virtual seminar on Sept. 21. Register here. Researcher Tripti Vashisth told the recent Citrus Expo audience how fruit drop might be reduced through the use of nutrition and irrigation strategies, gibberellic acid and increased fruit …
Australia’s New South Wales (NSW) government is growing citrus on trellis systems in an effort to reduce vigor, increase flowering and fruit production, and potentially open the way to robotic harvesting. The trial being conducted by NSW’s Department of Primary Industries (DPI) at the Dareton research center is part of the National Tree Crop Intensification in Horticulture project. The …
According to researchers in Florida and California, kaolin clay, especially red kaolin, aids in the management of Asian citrus pysllids (ACP) and the HLB they spread, among other attributes. Christopher Vincent of the University of Florida Institute of Food and Agricultural Sciences and Monique Rivera of the University of California at Riverside recently presented a webinar about kaolin. The University …
Scientists from Nanyang Technological University (NTU) in Singapore have identified a key mechanism by which the dangerous plant bacteria Xanthomonas can infect crops. The Xanthomonas bacteria, known as the “crop killer,” is a globally prevalent bacterium capable of infecting 400 different plant species. Citrus canker is caused by the bacterial pathogen Xanthomonas citri subsp. The NTU researchers identified the exact …
By Ben Chapman, Taylor O’Bannon, Matt Krug and Michelle Danyluk If you would have asked us last September if there would still be a need to write a tip about COVID-19 a year later, our answer would have been, “We sure hope not.” So, what’s changed? The simplest explanation is the emergence of the Delta variant. When you hear us …
An innovative way to manage huanglongbing (HLB) disease is producing impressive results in University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research. According to Arnold Schumann, UF/IFAS professor at the Citrus Research and Education Center (CREC), citrus under protective screen (CUPS) production systems have increased yields with zero effect from HLB. He shared research results during a recent …
In late August, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) removed a portion of Harris County within the Braeswood area of Houston, Texas, from citrus canker regulations. APHIS reported that the successful partnership between itself and the Texas Department of Agriculture (TDA) has resulted in a citrus canker-free status in the area since 2016. On …
Fabric mulch landscape covers, typically used to block weeds in nurseries, can aid in diaprepes root weevil control, Larry Duncan reported at the recent Citrus Expo. “Some of these products, not all of them, are extremely effective at blocking the diaprepes weevil larvae from getting into the soil” after falling from a citrus tree, Duncan said. Duncan is a University …
