Below you'll see everything we could locate for your search of “rootstock”
HLB continued to contribute to reduced production and lower quality fruit for Florida growers this season. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are working to help alleviate these problems by delivering improved rootstocks and varieties. The July issue of Citrus Industry magazine includes an in-depth look at this work. Read “Juice for Florida’s future” to …
By Ute Albrecht, Gabriel Pugina, Antonio Castellano-Hinojosa and Sarah Strauss Root health is important for tree growth and directly affects a tree’s ability to cope with adverse biotic and abiotic stresses. Most citrus production in Florida occurs on natural infertile sands with very little organic matter and a low cation exchange capacity (CEC), resulting in minimal amounts of soluble nutrients …
By Anirban Guha and Christopher Vincent A quick body temperature test is common these days before entering many workplaces, hospitals and clinics due to the ongoing COVID-19 pandemic. The purpose is to screen people for fevers, usually with a non-contact infrared thermometer. Measurement of plant body temperatures also has become common for many field crops, not to screen for infectious …
By Amit Levy Citrus tristeza virus (CTV) infects the citrus phloem. CTV infects almost all citrus varieties, but it causes different disease symptoms depending on the virus isolate, the citrus variety and scion-rootstock combination. Florida has three dominant strains of CTV: T36, a decline-causing strain T30, which normally does not cause severe disease VT, a stem-pitting causing strain CTV is …
The Citrus Research and Development Foundation (CRDF) held its April board of directors meeting to hear reports on projects involving 2,4-D, gibberellic acid, brassinosteroids and zinc. According to Rick Dantzler, chief operating officer of CRDF, the foundation is conducting a full-court press to study how these materials can combat fruit drop and improve quality. CRDF staff also presented a proposal …
Jake Price with University of Georgia Extension in Lowndes County provided an update on pruning of South Georgia citrus trees in a recent Cold Hardy Citrus Connection newsletter. The newsletter is published by the University of Florida Institute of Food and Agricultural Sciences. His report follows: In February 2021, we pruned the Owari rootstock trial trees to where most limbs …
Muhammad Adnan Shahid in January joined the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) North Florida Research and Education Center (NFREC) as assistant professor of horticulture/fruit crops specialist. His Extension goal is providing fruit producers, particularly cold-hardy citrus growers, with relevant, research-based information for improving productivity, profitability and produce quality. Shahid is interested in evaluating new early …
By Davie Kadyampakeni and Evan Johnson In the era of citrus greening disease (huanglongbing, HLB), maintaining optimal nutrition and disease/pest management strategies is critical for avoiding adverse effects on tree performance. Use of the right fertilization rate, timing and placement are important for optimal citrus production. In a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research study, …
The area of Falfurrias, Texas, was a very prosperous citrus-growing region from 1909 until 1951, according to Romulo Montilla, who has a ranch there. “However, in 1951 there was a freezing temperature that killed close to 90% of the citrus. In 1967, the remaining citrus was eliminated with another terrible freeze.” Montilla and others recently began working to return citrus …
By Kelly T. Morgan and Davie Kadyampakeni Most information provided in the 2020 3rd edition of Nutrition of Florida Citrus Trees is still sound for healthy citrus trees under Florida production conditions. Past information on nutrients, application methods, leaf and soil sampling, and irrigation scheduling are also effective for management of huanglongbing (HLB)-affected trees. However, research conducted since HLB was …
John Chater joined the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) in January as an assistant professor of horticultural sciences. His mission is to act as a conduit between citrus plant breeders and growers to find fits for new rootstock and scion selections. Chater’s love of plants was inspired by his grandfather who was a plant breeder …
By Ajia Paolillo Managing diaprepes root weevils in the grove is essential for root health and overall tree health. The most concerning root weevil for citrus growers is Diaprepes abbreviatus. Diaprepes larval feeding causes significant injury and damage to citrus root systems. LIFE CYCLE AND FEEDING Let’s begin with the life cycle stages of the diaprepes root weevils. Adults emerge …
Early results from a large-scale citrus trial looking for solutions to HLB, also called citrus greening, show tree size does not seem to affect citrus susceptibility to the disease. The trial is being conducted in the Indian River region by researchers with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). They are testing which citrus rootstock and …
During the March All In For Citrus podcast, Michael Rogers, director of the Citrus Research and Education Center, gave props to graduate students in the citrus program at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). There are 65 students currently enrolled in the program carrying out their studies across the state. “Graduate students play a huge …
The Australian finger lime has created a buzz among chefs and mixologists for its caviar-like texture and flavorful pulp. The fruit also has captured interest among growers for its seemingly high tolerance to HLB. On March 23, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a half-day online symposium on finger limes to provide growers with …
March means spring break for many, and Florida is a favorite destination for students looking to celebrate the time off. Michael Rogers, director of the Citrus Research and Education Center in Lake Alfred, took the occasion to shine the light on the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus graduate program. Sixty-five students are currently engaged …
By Fernando Alferez, Ute Albrecht, Susmita Gaire, Ozgur Batuman, Jawwad Qureshi and Mongi Zekri University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers established a field trial in February 2018 to evaluate the efficacy of individual protective covers (IPCs) to prevent Asian citrus psyllids from spreading HLB and to study the effects on tree growth and physiology. The …
There has been quite a bit of interest in the Citrus Research and Field Trials (CRAFT) program. During the Florida Citrus Show held in Fort Pierce in late January, a panel of citrus growers discussed projects they have been approved to conduct under CRAFT. Tamara Wood, executive director of the CRAFT Foundation, moderated the panel and provided an update on …
The pathogen phytophthora has long presented problems for Florida citrus growers. But the HLB disease that has plagued Florida since 2005 reduces the efficacy of phytophthora management, citrus pathologist Ozgur Batuman reported in a recent virtual seminar. Batuman, who works for the University of Florida Institute of Food and Agricultural Sciences, said improved fungicide timing, number of applications and rates …
