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 …
Fermented Food Waste for Fertilizing Citrus
Fermented food waste converted to liquid fertilizer and fed through drip irrigation can boost bacteria that increase crop growth, according to a new University of California Riverside (UCR) study. The treatment may also make plants more resistant to pathogens. “Beneficial microbes increased dramatically when we added fermented food waste to plant growing systems,” said UCR microbiologist Deborah Pagliaccia, who led …
Time to Cut the Dead Wood
By Megan Dewdney, Tripti Vashisth and Lauren Diepenbrock Dead wood has long been challenging for fresh citrus fruit production. Spores in twigs can form which cause blemishing diseases that downgrade fruit for lower profits. More recently, it has come to light that there are horticultural and entomological reasons to remove this wood as well. Many growers are familiar with melanose, …
Making Sense of Biologicals: Interest Increasing in Biologicals
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 …
Pieces of the Past: Waverly’s Window
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 …
Compost Use and Weed Management
By Ramdas Kanissery Application of compost as a soil amendment could be an integral part of citrus production’s best management practices. Compost application can potentially improve soil quality and provide additional nourishment to trees. Citrus-producing soils in Florida are generally sandy and low in soil organic matter. Compost addition tends to enhance the soil’s ability to retain both nutrients and …
Flowering Intensity, Shoot Dieback and HLB
Citrus trees grown in Florida continuously undergo various types and levels of stress. Stressors can include severe weather conditions, soil pH, chemicals, pests and diseases. The constant presence of HLB and psyllid infestation adds further stress to the tree, compromising overall tree health. Off-season flowering and prolonged flowering are common responses of trees when undergoing various stress conditions. Off-season and …
High-Tech Scouting in Citrus Production
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 …
Grower Discusses Conservation Steps
Travis Miller, part owner and manager of the 330-acre DeSoto Grove in DeSoto County, was recently recognized by the Florida Farm Bureau Federation for his natural resource conservation efforts. Miller and 22 other Florida farmers and ranchers received the Farm Bureau’s County Alliance for Responsible Environmental Stewardship (CARES) award. Miller reports on the conservation steps taken at DeSoto Grove: “We …
Citrus Growers Honored for Conservation
Two citrus growers are among 22 farmers and ranchers recently honored by the Florida Farm Bureau Federation (FFBF) in recognition of their superior natural resource conservation efforts. They are Travis Miller of DeSoto Grove in DeSoto County and Marlon Pendergrass of The Groves of Peace River in Hardee County. Each received the Farm Bureau’s County Alliance for Responsible Environmental Stewardship …
The Effect of the Clean Waterways Act on Ag
The Clean Waterways Act (Senate Bill 712) was signed into law on June 30 by Gov. Ron DeSantis. The act discusses several mechanisms and provisions to protect waterways by reducing water pollution. It includes a few changes that directly affect the agriculture industry. The law requires the Florida Department of Agriculture and Consumer Services (FDACS) to perform onsite implementation verification …
Proper storage of pesticides
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 …
Enhancing Soil Health With Cover Crops
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 …
Irrigation Problem Prevention
By Ajia Paolillo To keep your irrigation system running efficiently, it is important to perform routine maintenance throughout the year. There are many types of issues that can affect your irrigation system, causing it to run poorly. Poly tubing and emitters can become clogged. Emitters can be blocked by weeds or broken through normal wear and tear. When these issues …
Irrigation Scheduling to Optimize Tree Performance
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 …
Get the Science on Climate Change
“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 …
Artificial Intelligence System Wins UF Honors
UF Innovate | Tech Licensing recently recognized an artificial intelligence (AI) system known as Agroview as a UF Invention of the Year.

The system utilizes images from drones and satellites …
Use More Micronutrients for HLB
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 …
Growers Sustain Losses
Not many watching a recent virtual Citrus Expo presentation were surprised by Ariel Singerman’s declaration that “taking into account total cost, on average, growers sustained a loss” in the 2019-20 Florida citrus season. Singerman, a University of Florida Institute of Food and Agricultural Sciences economist, pegged the average per-acre losses at $1,606 for early-midseason oranges and $1,254 for Valencias. Singerman …
