University of Florida Institute of Food and Agricultural Sciences researcher Rhuanito “Johnny” Ferrarezi reports on research leading to fertilizer recommendations for grapefruit, especially in the Indian River area. Grapefruit has been especially hard hit by HLB, the devastating citrus disease discovered in Florida in 2005. “We are entering the second season (of the research project) and we hope to have …
By Ernie Neff It’s common belief — and probably true — that small Florida citrus growers have suffered more than larger growers as a result of HLB. Del Murphy might agree, but his family’s 66-acre citrus grove east of Avon Park is doing well by any Florida standard. He says the Murphy Partnership production program seems to be working “as …
“A bigger gorilla by far than HLB, going into the future, is slumping market demand for citrus products from Florida and apparently from other producing areas in the United States as well,” declares Apopka citrus grower Chip Henry of McGuire Groves. He believes the decline in demand for Florida citrus products is related to HLB reducing fruit quality. “Consumers are …
Laboratory tests of tricalcium phosphate (TCP) indicate it has potential use as a fertilizer that might help citrus growers cope with HLB, says Laura Waldo, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) laboratory manager. “The hope is that it can help a tree by inducing root hair development and thereby allowing the tree to uptake nutrients …
By Stephen H. Futch and Ariel Singerman As home to three of the world’s major religions, Israel is one of the most diverse countries in the world. Besides its cultural diversity and historical importance, Israel is also a major citrus producer and exporter. Israel’s citrus industry began in 1882. As new immigrants moved to the country, they established many very …
Growers of one of Florida’s signature citrus crops may see more production and possibly less of the deadly citrus greening disease. Researchers have worked for four years growing grapefruit under protective screens on a 1-acre experimental plot at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), and they’re seeing encouraging results. UF/IFAS scientists and a few commercial …
By Tripti Vashisth, Davie Kadyampakeni and Lushan Ghimire In the past few years, horticultural citrus grove management practices have changed significantly in Florida. It is a common observation across the state that huanglongbing (HLB)-affected trees respond well to complete and balanced nutrition programs. Therefore, citrus growers are currently focusing on intensive management of irrigation and nutrition. HLB-affected trees suffer a …
By Arnold Schumann, Laura Waldo, Tripti Vashisth, Alan Wright and Kelly Morgan Huanglongbing (HLB) disease severely impacts the nutrient status of citrus trees, particularly by stunting the feeder roots and causing measurable deficiencies of nutrients in the roots and canopies. Visible symptoms of nutrient deficiencies on citrus foliage are characteristic but not diagnostic of HLB disease. Recent HLB research efforts …
By Sarah Strauss, Davie Kadyampakeni, Ramdas Kanissery, Tara Wade, Lauren Diepenbrock and Juanita Popenoe Cover crops are specific crops not intended for sale but for soil improvement and sustainability. They are increasingly common in the agricultural fields of the Midwest and other grain-producing regions because of the wide range of benefits not just for the soil, but also the cash …
By Juanita Popenoe and Lauren Diepenbrock Ed James has citrus in his veins. He has been working and thriving in the citrus business since he was a teenager — from hoeing orange trees to owning a caretaking business that serviced thousands of acres. That is, until about eight years ago. In 2010, James looked around his personal 45-acre citrus grove …
By Lorenzo Rossi, Ute Albrecht and Evan Johnson Citrus root systems are confronted with many challenges that limit resource availability needed for tree productivity. Challenges are compounded by huanglongbing (HLB), which now affects nearly all citrus trees throughout Florida’s production areas. Contrary to the above-ground portion of the tree, study of the below-ground portion is considerably more difficult. This article …
By Brenda Eubanks Burnette I found the first issue (January 1920) of Citrus Industry, courtesy of Jen Dawson at the Citrus Research and Education Center in Lake Alfred, Florida. As I looked through the issue, I came across an article on soil tillage. Unfortunately, the pages had stuck together and only the last part was readable, but I wanted to …
Many things are improving in Florida citrus groves, and Tripti Vashisth gives most of the credit to constant and balanced fertilization. Vashisth is an assistant professor at the University of Florida Institute of Food and Agricultural Sciences Citrus Research and Education Center in Lake Alfred. “You can see that tree health seems to be improving; growth is improving,” Vashisth said. …
Citrus growers discuss production practices to improve root health. By Tacy Callies What began as an experiment in Ben Krupski’s 10-acre grove in Howey-in-the-Hills, Florida, is now a common practice he uses as production manager for Lennon Grove Service. Four years ago, Krupski started testing the use of compost in his small leased block of Hamlin trees. In the first …
By Brenda Eubanks Burnette The headline of a Wilson & Toomer Fertilizer Company advertisement in a 1949 Citrus Industry magazine read “how to think UPSIDE DOWN — and make more money!” It included the following copy: “If a tree can be said to think at all — it thinks from the bottom up — just opposite to Man. To make …
Citrus Expo is just six months away, which means the planning process has started for the seminar program. Growers of citrus, vegetables and specialty crops will once again have the opportunity to earn continuing education units and Certified Crop Adviser credits at the event. Citrus Expo will kick off with a general session on top agricultural issues of importance to …
Among other topics she discussed in her part of the latest All In For Citrus podcast, Laurie Hurner emphasized that HLB is here to stay. Hurner is the Highlands County Extension director and a citrus Extension agent. “At some point we do have to make the decision in the field, at the grower production level and at the higher levels …
Coalitions of San Joaquin Valley growers created to help comply with water quality regulations have reached a settlement agreement with the State Water Resources Control Board (SWRCB). The coalitions include the Kaweah Basin Water Quality Association, Tule Basin Water Quality Coalition and Kings River Watershed Coalition Authority. As part of the agreement, the coalitions will install kiosks to ensure safe drinking …
Grower Roy Petteway told fellow growers attending a recent grower roundtable meeting in Arcadia that his 400 acres of citrus groves in three counties are averaging production of 325 boxes per acre. That’s approximately double the production level of the average Florida citrus acre hammered by HLB, though far below pre-HLB production levels. Petteway grows fruit for processing in DeSoto, …
