Where to Watch for Diaprepes Root Weevil
By Larry Duncan Prior to the introduction of citrus greening disease in Florida, certain conventions applied to the occurrence and impact of diaprepes root weevil in groves across the state. The abundance and damage potential of this major pest were greatest in some Flatwoods habitats, such as parts of the inland East Coast where newly planted trees sustained major damage. …
Phytophthora: A Complex Problem
While the recent Florida Citrus Growers’ Institute presentations focused mainly on HLB, other topics were addressed, including phytophthora root rot. This disease has become more problematic in recent years. Megan Dewdney, University of Florida Institute of Food and Agricultural Sciences associate professor of plant pathology, spoke on the topic. She noted that phytophthora already is a complex problem and that …
Finger Lime Field Day Draws Mostly Non-Citrus Crowd
Only a few Florida commercial citrus growers were on hand for an April 24 finger lime field day at the Citrus Research and Education Center (CREC) in Lake Alfred. Most of the more than 40 attendees did not own citrus groves, and about half were women — definitely not the standard crowd for a CREC event. Those in attendance had …
Big Yields Expected in Georgia
A December 2022 freeze in Georgia significantly reduced the state’s 2023 citrus production, but many growers anticipate a large crop in 2024. “With less fruit production in 2023, trees added a lot more vegetative growth and increased their canopy volume,” University of Georgia Extension citrus agent Jake Price noted. “The satsuma bloom at the research plot was very large and …
Sneak Peek: May 2024 Citrus Industry
Inside the May issue of Citrus Industry magazine, you’ll find photos and coverage from the Florida Citrus Show. The annual grower-focused event was held in Fort Pierce on April 3.

Grove First Project Seeks More Grower Cooperators
The Grove First project plans to expand next year and is seeking additional growers as cooperators. The project tests molecules directly in the field for their ability to treat HLB via trunk injection. The Grove First project differs from the common practice of starting HLB research in the laboratory, then moving to the greenhouse to be confirmed before going into …
Covering the Basics of Summer Cover Crops
By Sarah Strauss The recent rising temperatures are a reminder that summer is approaching, and the beginning of the rainy season is a great time to start planting cover crops. If you are looking for a method to invest in your soil health, cover crops are one option. By definition, cover crops are planted to improve soil health and are …
Irrigation Frequency Critical to Fight Tree Stress
During the month of April, Florida rainfall has been scarce. Groves are drying out after some areas enjoyed more rain than normal during the El Niño winter. The dry weather has growers busy running irrigation. Keeping HLB-infected trees well-watered is especially important to reduce plant stress. That was the message Tripti Vashisth, University of Florida Institute of Food and Agricultural …
The Effect of Soil pH on Nutrient Availability
By Chris Oswalt Soil pH influences nutrient availability. This article considers the specific fate of nitrogen, phosphorus and potassium in soils with elevated pH values. The discussion also assumes that these effects would be similar to conditions in the wetted zone where micro-sprinkler irrigation has raised soil pH. NITROGEN Soil pH can affect several reactions involving nitrogen in the soil …
All In For Citrus Podcast, April 2024
April was a busy month for citrus events. The Florida Citrus Show was held April 3 in Fort Pierce followed by the Florida Citrus Growers’ Institute in Avon Park on April 9. These events were a topic of discussion between All In For Citrus podcast host Frank Giles and Michael Rogers, director of the University of Florida Institute of Food …
In Georgia Owari Trial, Yields Peaked in 2021
University of Georgia Extension agent Jake Price recently summarized yields for three recent seasons from Owari satsuma trees in a rootstock trial. Last year, 2023, was the last harvest year for data collection in the trial. Price reported that yield in the trial plot peaked in 2021 with a yield of about 20,300 pounds on 60 trees, which would be …
PIECES OF THE PAST: Citrus Sprayer Innovation
By Brenda Eubanks Burnette In the early 1900s, there were a number of inventions made to help the growing citrus industry flourish. One of those inventions took place in Winter Haven at the Van Fleet Company in Florence Villa. The company manufactured the Van Fleet sprayer. An article in the May 1920 issue of The Citrus Industry magazine described it …
Managing the Eastern Lubber Grasshopper
Eastern lubber grasshoppers are out in force in some parts of Florida, munching away on citrus, vegetable crops and landscape plants. They can be found from March or April to about October or November in North Florida and the state’s Gulf Coast. They can be economically important throughout Florida. Eastern lubber grasshoppers can completely strip foliage from plants. More commonly, …
Grower Panel: OTC a Net Positive So Far
Florida Citrus Mutual recently hosted a roundtable discussion about the performance of trunk-injection therapies as growers are making their second round of applications. The grower participants included Jim Snively, Southern Gardens Citrus; Glenn Beck, Beck Bros. Citrus and Wes Soria, Sorrells Citrus. University of Florida scientist Ute Albrecht also joined the panel to provide a research update. Rick Dantzler, chief …
California Citrus Breeding Program Gets More Funds
The presidents of the Citrus Research Board (CRB) and California Citrus Mutual (CCM) applauded congressional leaders for recently approving additional funds for the new citrus breeding program in Parlier, California. Congress is allocating an additional $500,000 in federal funding on top of the $1 million granted last year to expand the program into California. The program will now receive $1.5 million in …
Optimizing Organic Nutrient Sources
By Davie Kadyampakeni The use of certified organic nutrient sources (manures, composts, biochar, biosolids, etc.) should be considered by Florida commercial citrus growers to improve the soil properties and long-term nutrient availability of the predominantly sandy soils. Use of the organic residues could be incorporated in the soil during tillage to plan a new grove or periodically to an existing …
Determining Planting Density
As growers grapple with planting new blocks in the HLB era, there has been considerable discussion about planting densities to optimize growth and yield. John Chater, assistant professor of horticultural sciences with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), has been working with growers in evaluating new varieties and rootstocks as trees are planted. TRENDING HIGHER …
