A solid nutrition and irrigation program can enhance the productivity of HLB-affected trees and improve citrus tree health, potentially making production profitable even under HLB conditions. This was the subject of Davie Kadyampakeni’s talk during a March 9 OJ Break virtual meeting held for citrus growers. Kadyampakeni is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant …
Fertilizers help crops reach maximum yields while fungicides prevent diseases. But what if there were products available that could further enhance the fruiting qualities all growers hope to achieve every season? IMPROVED FRUIT PRODUCTIONIf growers can increase the level of flowering hormones in their crops, this will allow for a better fertilization process that will generate improved fruit set and …
An article in the January Cold Hardy Citrus Connection newsletter offered basic nutrition management information for North Florida growers. It was written by Lisa Strange with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Taylor County Extension and Clay Olson, UF/IFAS Extension faculty, emeritus. A grower’s first nutrient management consideration is to have a soil test, the …
By Clint Thompson Increased interest in biologicals stems from their long-term sustainability and the belief that synthetic materials have reached their ceiling of productivity. Tate McPherson, vice president of marketing and business development at Douglas Plant Health (DPH), shares those sentiments about biologicals, which represent a group of products derived from living organisms. Farmers utilize these environmentally friendly products in …
By Brenda Eubanks Burnette I grew up in Winter Haven and have driven by Waverly Growers Cooperative countless times when traveling around Polk County. But I never knew that at one time there was a formal garden and picnic grounds adjacent to the Waverly Welcome House. Founded in 1914 by a group of local growers led by Charles Hillery Walker …
By Yiannis Ampatzidis and Tara Wade Traditional sensing technologies in citrus production for pest and disease detection and field phenotyping rely on manual sampling, which is time consuming and labor intensive. Since availability of personnel trained for field scouting is a major problem, small unmanned aerial vehicles (UAVs) equipped with various sensors and artificial intelligence (AI) can simplify the surveying …
By Ajia Paolillo Editor’s note: This article grants one continuing education unit (CEU) in the Core category toward the renewal of a Florida Department of Agriculture and Consumer Services restricted-use pesticide license when the accompanying test is submitted and approved. Pesticides are widely used in the citrus industry and are important tools in agricultural production. Safety precautions should be taken …
By Sarah Strauss, Antonio Castellano-Hinojosa, Davie Kadyampakeni, Ramdas Kanissery and Tara Wade Soil health is generally synonymous with soil quality and refers to the capacity of a soil to sustain biological productivity, maintain environmental quality and promote plant health. Soils are complicated ecosystems, and discussions of soil health must consider the links between soil functions and soil-based ecosystem services, such …
By Davie Kadyampakeni Proper irrigation scheduling applies an appropriate volume of water to a citrus grove at the appropriate time based on tree need, soil properties and weather conditions. Applying water in the right amount, right quantity and at the right time is very important for getting the best out of citrus trees. Several tools are available for determining when …
“Our climate is changing and, with that, comes more extreme events,” said Ashley Smyth, an assistant professor of soil and water science at the Tropical Research and Education Center in Homestead. The center is part of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). “Just look at the most recent hurricanes. As they cross the Gulf, they …
UF Innovate | Tech Licensing recently recognized an artificial intelligence (AI) system known as Agroview as a UF Invention of the Year. The AI system was invented by Yiannis Ampatzidis and his research team at the University of Florida Institute of Food and Agricultural Sciences Southwest Florida Research and Education Center (SWFREC). The system utilizes images from drones and satellites …
HLB-affected citrus trees benefit from micronutrients at higher-than-recommended rates, Tripti Vashisth reported in a virtual Florida Citrus Growers’ Institute presentation. Vashisth, a University of Florida Institute of Food and Agricultural Sciences researcher, said that a 20 percent higher-than-recommended rate of micronutrients can improve productivity in trees with HLB. The Florida Citrus Growers’ Institute is normally held in Avon Park in …
Florida’s new Clean Waterways Act impacts agricultural landowners and producers enrolled in the Florida Department of Agriculture and Consumer Services (FDACS) Best Management Practices (BMPs) program. The act went into effect July 1. FDACS is required to undertake implementation verification (IV) site visits on properties enrolled in the BMP program every two years. During these IV site visits, FDACS Office …
By Ariel Singerman Four reports summarizing Florida citrus industry survey-collected data during the 2019–2020 season are available at https://crec.ifas.ufl.edu/economics/. The reports include the average cost of production for processed oranges, harvesting charges, custom rate (or caretaking) charges and packing charges. The estimates presented in those reports, as well as those available for previous seasons, document the changes in the industry …
By Manjul Dutt and Jude Grosser Finger lime, a distant relative of sweet orange and grapefruit, is a relatively new crop species for Florida. It is an Australian native species that has been gaining in popularity and importance in the last few years because of its unique fruit characteristics and disease tolerance, which sets it apart from conventional sweet orange …
By Yu Wang, Fred Gmitter and Jude Grosser A major concern for the citrus industry is a significant decline in production due to huanglongbing (HLB). In addition to the production shortfalls are losses due to fruit rejection by packinghouses and juice processing plants as a result of inadequate size and low sugar content. Bitterness and metallic off flavors in the …
By Rhuanito S. Ferrarezi, William S. Castle, Kim D. Bowman, Jude W. Grosser, Stephen H. Futch, Steve Rogers and Andres Gonzalez First published in 1989 as Rootstocks for Florida Citrus, the work of William Castle and his colleagues remains relevant 30 years later. The purpose of the fourth edition of the Florida Citrus Rootstock Selection Guide is to provide timely …
By Fernando Alferez and Tripti Vashisth As summer approaches and citrus trees bear developing fruit, growers can engage in several practices to improve fruit quality and yield. As temperatures rise and daylength increases, conditions are conducive for enhanced photosynthesis and accumulation of soluble sugars in the fruit. It is important to note that, in general, the temperature is negatively correlated …
By Sean Stokes, Thomas Borch and Pankaj Trivedi The benefits of soil organic matter (SOM) in agriculture have been well documented and include both improved water and nutrient retention. SOM is also essential for a properly functioning rhizosphere microbiome. However, the natural level of SOM in the sandy, acidic soil of Florida’s citrus grove regions is often around 1 percent, …
In his quest to find the right drone and other artificial intelligence to help ensure citrus growers get an accurate count of their crop, Yiannis Ampatzidis and his research team have developed a system known as Agroview. The technology saves farmers time and money and helps them accurately count their trees, which is important for insurance purposes. The latest results …
