By Davie Kadyampakeni, Alisheikh Atta and Edilaine Traspadini Citrus trees require optimal nutrition to be able to maintain high fruit yields, canopy size and good root health. Adequate nutrition supports not only yield and growth, but also tree resilience to disease and environmental stress, which is particularly important in HLB-affected groves. A balanced mix of macronutrients and micronutrients is needed …
In the latest All In For Citrus podcast, Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, discussed a statewide citrus workshop hosted at the Southwest Florida Research and Education Center in January. The event provided a day full of educational presentations covering a wide range of topics. Rogers …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have long extolled the virtues of individual protective covers (IPCs). Multi-county citrus Extension agent Edwin Gutierrez-Rodriguez does the same but also warns of potential risks. Following is information from a recent UF/IFAS blog article he authored. In the ongoing battle against huanglongbing (HLB), also known as citrus greening disease, …
By Muhammad A. Shahid, KeAndre Leaks and Davie M. Kadyampakeni Right after a freeze, you may notice new growth turning black and leaves hardening, yellowing or looking water-soaked. About a week after a severe freeze, leaves may start to curl and turn brown. Leaves and fruits may begin to drop. Do not attempt any recovery treatments immediately after a freeze. …
Chinese researchers have delved into the complex interactions between transcription processes and metabolism in sweet orange plants deficient in boron. Boron deficiency can lead to reduced yields and compromised fruit quality. Authors of the research are Xiuyao Yang, Ke Wen, Xiujia Yang, Mengjie Zhang, Ling Zhu, Yinqiang Zi, Tuo Yin, Xulin Li, Xiaozhen Liu and Hanyao Zhang, all with the …
Noting that magnesium (Mg) deficiency is a problem in Florida citrus, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) offers the following information about its symptoms, cause and solutions. SYMPTOMS AND CAUSE Trees with inadequate Mg supply have no symptoms in the new spring flush, but leaf symptoms will develop as the leaves age and the fruit …
California Citrus Mutual (CCM) recently reported on the changes to citrus tariffs as a result of President Trump’s executive order modifying the scope of the administration’s reciprocal tariffs. Lemons and mandarins remain subject to reciprocal tariffs, ensuring continued tariff parity during the domestic growing season. Oranges and limes were newly exempted, and grapefruit was exempted only during the month of …
By Michael Rogers It has now been two decades since huanglongbing (HLB), or citrus greening, was first detected in Florida. That announcement in August 2005 changed everything for the Florida citrus industry. At the time, Florida citrus was still a global powerhouse. Less than a year earlier, HLB had been confirmed in Brazil, and we were aware of its devastating …
Mountain Valley MD Holdings Inc. (MVMD) recently reported positive results from ongoing citrus field trials in Brazil for its Agrarius™ signaling technology. Agrarius™ is designed to organically increase crop yields, reduce fertilizer and pesticide usage and enhance plant health. MVMD has been working with a client-directed third-party agricultural partner, FARM ATAC, in Brazil to assess the impact of the application …
In a recent study, Chinese researchers found that citrus seedlings clearly prefer nitrate over ammonium as a nitrogen source. The researchers — Hao Xu, Wenlang Hu, Kaiyuan Du, Yan Dong, Qingru Fan, Zengrong Huang, Lin-Tong Yang, Li-Song Chen and Jiuxin Guo — are with the Fujan Agriculture and Forestry University. In their study, the researchers compared two citrus cultivars (C. reticulata …
A recent tour of Brazilian citrus provided Georgia growers with valuable information on how to capitalize on production amid huanglongbing (HLB) disease. Lindy Savelle, executive director of the Georgia Citrus Association and owner of JoNina Farm, was one of seven producers who attended the week-long tour this fall. One of the main observations was Brazil’s strong production despite the prevalence …
By Muhammad A. Shahid, Shahid Iqbal and Davie Kadyampakeni As temperatures begin to drop across citrus-growing regions, now is the time for growers to prepare their groves for potential freeze events. Citrus trees, especially young plantings, are susceptible to cold temperatures. Damage from a single freeze event can result in canopy dieback, fruit loss and even tree death. Proper planning …
By Edwin Gutierrez-Rodriguez and Bosques Jonael Replanting a citrus grove can be an exciting prospect, but it’s not as simple as swapping trees. New cultivars, for example, may require a different setup. Here are some aspects to consider before jumping in: First steps: Newly released cultivars and rootstocks as wells as the Citrus Research and Field Trial programs are refreshing the …
Sponsored Content Question: Previous questions have been asked about increases in yield and quality of the citrus crop as groves begin to recover from HLB. Why does it take additional time to get quality to improve? Answer: The ability of any crop to produce both high yield and high quality is an agronomic function of a plant’s ability to intake …
Agromillora, in collaboration with the Valencian Institute of Agricultural Research (IVIA), has introduced CIVAC-19, a new citrus rootstock. CIVAC-19 is the result of more than a decade of research between IVIA and Agromillora. It is a hybrid rootstock of Citrus reshni (Cleopatra mandarin) and Poncirus trifoliata (trifoliate orange). Its semi-dwarfing nature provides medium vigor, key for maintaining compact canopies and …
By Mongi Zekri 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. A minimum score of 70% is required to receive credit. Pesticides should not be considered the first line of defense against …
By Davie Kadyampakeni, Alisheikh Atta, Jonas Pereira de Souza Junior, Christopher Vincent and Tripti Vashisth Typically, citrus water requirements are low in the winter and spring due to cooler temperatures but peak in summer and early fall due to rising temperatures. Thus, improved irrigation management is critical in these times of the year for improved production. Because most citrus trees …
A bed system used in citrus groves is still under research at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center (NFREC) in Quincy. But one researcher is already convinced that the system, which includes fabric mulch, is beneficial for growers. “This system is better for them. It’s already being used in …
Varieties and rootstocks are the topics of the September episode of the All In For Citrus podcast. Earlier this month, a field day was held in Jason Griffin’s grove near Lake Alfred, Florida. He is collaborating with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) to evaluate several rootstock/scion combinations developed by UF/IFAS citrus breeders. Griffin has …
Minimal satsumas this harvest season will impact cold-hardy producers far beyond the loss of production in the region. MAINTENANCE MANDATORY Growers are now tasked with maintaining their groves when there is little to no fruit on the trees. It is a chore that producers should still follow through on, however, says Jake Price, University of Georgia (UGA) area citrus agent. …
