By Ute Albrecht, Anas Fadli and Chandrika Ramadugu Most commercially available citrus scion cultivars are highly attractive to the Asian citrus psyllid and susceptible to HLB. There are some citrus species, however, that are HLB tolerant or resistant. This may be because they are less attractive to the psyllids and/or because they restrict pathogen proliferation and therefore HLB disease development. …
By Anirban Guha Heat stress could take a toll on citrus tree health and fruit yield. In Florida, the hot season lasts more than four months. Long, hot, oppressive summer days can heat up leaves and fruit and make the trees extra thirsty. Also, high soil evaporation, irregular rainfall and poor soil water-holding capacity can often lead to summer drought …
By Sarah Strauss, Antonio Castellano-Hinojosa, Davie Kadyampakeni, Ramdas Kanissery and Tara Wade Cover crops, which are planted specifically for soil enhancement and not for sale or harvest, can improve soil conditions and production for a variety of crops. However, there have not been many studies documenting changes to soil conditions and production when using cover crops in citrus. The University …
By Ajia Paolillo Florida citrus growers are undoubtedly under pressure while they work daily to maintain tree health and produce quality fruit that is profitable. Growers are constantly switching gears to budget increasing production costs, address labor issues and, of course, fight HLB and other problems in the grove. Growers are fighting HLB from many different directions, including enhanced nutrition, …
By Brad Turner Cover cropping and composting in Florida citrus production are not new concepts. Our ancestors understood the basic principles and implemented these practices just a couple of generations ago. YESTERDAY AND TODAYAs a boy, I can remember an old citrus grower telling me how beggarweed and crotalaria, both native nitrogen-fixing legumes, growing wild in neighboring fields would be …
By Brandon White This time of year is the end of the peak nutrient demand for citrus trees. Regardless of the types of fertilizer or inputs applied in the groves, trees have been taking up nutrients while growing in full tilt during the spring season. One of the greatest factors determining how well trees take up nutrients is soil pH. …
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 …
By Lauren Diepenbrock, Megan Dewdney, Fernando Alferez, Jawwad Qureshi and Ozgur Batuman Individual protective covers (IPCs) are becoming commonplace in citrus production to support the development of young trees after planting. IPCs are made of fine mesh and are intended to keep Asian citrus psyllids (ACP) off young plants. Because ACP can transmit the pathogen that causes citrus greening/huanglongbing, preventing …
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 …
After being presented virtually for the past two years as a result of COVID-19, the 2022 Florida Citrus Growers’ Institute will once again be an in-person event on April 5. The event will be held from 8:30 a.m. to 3 p.m. at South Florida State College’s Alan Jay Wildstein Center for the Performing Arts in Avon Park. The institute is …
Increased attention on nutrition has become part of the overall strategy for managing HLB. The April issue of Citrus Industry magazine includes several articles on nutrient management designed to help growers keep trees productive in the HLB era. Mandarin growers will want to take note of new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research on how …
By Lauren Diepenbrock, Megan Dewdney, Christopher Vincent and Davie Kadyampakeni As the threat of potential shutdowns loomed in March 2020, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) team put the final plants in the ground, individual protective covers (IPCs) on trees, and kaolin and pesticide applications on a 2.7-acre planting at the Citrus Research and Education …
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 …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has committed to updating nutrition recommendations for citrus now that HLB is endemic across the state. Some of this ongoing research was discussed during the February All In For Citrus podcast. Growers will be interested to hear from Davie Kadyampakeni, a UF/IFAS assistant professor of soil and water science, …
By Chris Oswalt, Mongi Zekri, Ajia Paolillo and Lourdes Pérez Cordero Huanglongbing (HLB) continues to impact citrus-producing areas of Florida. The 2022 Florida Citrus Growers’ Institute is an opportunity for Florida citrus growers to come together to learn about effective management of HLB and other challenges affecting the industry. This year’s event will be held Tuesday, April 5 from 8:30 …
By Brad Turner As I started my regenerative journey five years ago, it conjured up memories of walking the family groves in the 1970s with my freshly sharpened eye hoe. I would follow the tractor as it pulled the offset chopper, crisscrossing between the widely spaced trees in all directions. The native grasses and broadleaf plants — including legumes like …
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 …
Fire ant management is essential to the long-term sustainability of citrus groves. This is particularly true for young trees still trying to develop root systems, said Xavier Martini, assistant professor of entomology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center (NFREC). Martini spoke on insect management at the recent UF/IFAS …
Rick Dantzler, chief operating officer of the Citrus Research and Development Foundation (CRDF), gave an update at the recent Florida Citrus Show on the latest efforts to find solutions to the HLB problem. Dantzler acknowledged the frustration growers have expressed in the long battle against the disease and the challenge it has presented to the research community. Because of this, …
A $1.5 million emergency grant is enabling scientists in citrus-producing states to find trees tolerant to the devastating citrus disease HLB. The disease has crippled Florida’s citrus industry and has already been detected in California, which grows 80% of America’s fresh citrus. The National Institute of Food and Agriculture is supporting scientists at the University of California, Riverside (UCR); the University …
