By Muhammad A. Shahid, KeAndre Leaks, Davie Kadyampakeni and Carlos Aucique-Perez Postfreeze citrus tree management requires patience and careful observation rather than immediate intervention. Damage to the vascular system (cambium, xylem and phloem) may take months to fully appear. Trees can initially flush in spring but later decline if internal tissues are too compromised. A reliable assessment of survival should …
The Florida Fruit & Vegetable Association (FFVA) recently sought disaster aid in a letter to Florida’s congressional delegation and joined other agricultural groups in asking President Trump for economic assistance. FREEZE ASSISTANCE FFVA Chair Steven Callaham and President Michael Joyner on March 20 asked the Florida delegation’s support in securing supplemental disaster funding for Florida specialty crop producers affected by …
Brazil’s Fundecitrus reported on the benefits to citrus from the use of perennial cover crops such as Urochloa ruziziensis combined with the adoption of ecological mowing. This technology has been gaining space in groves by redistributing the phytomass of cover crops from the interrows to the planting rows, forming a protective mulching layer over the soil. Benefits of the management …
Edwin A. Gutierrez-Rodriguez and Jonael Bosques, both with University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension, recently explained why patience is an important post-freeze tree management strategy. Following are highlights from the article they wrote. After Florida’s recent freeze event, a common question citrus growers were asking was: “What should I do to recover the trees?” The …
By Tripti Vashisth, Abhishek Neupane and Taylor Livingston Florida citrus trees are under pressure from huanglongbing (HLB). The disease weakens root systems, reducing the tree’s ability to take up water and nutrients. Compounding this issue, most Florida groves sit on sandy soils with very little organic matter. These soils drain quickly, struggle to hold nutrients and allow both water and …
Irrigation and fertilizer applications are important management tools for Florida citrus growers following the recent freeze event in late January/early February. Davie Kadyampakeni, associate professor in soil, water and ecosystem sciences at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), discussed both facets of tree maintenance during a postfreeze webinar hosted by the UF/IFAS Citrus Team. Key …
Florida citrus growers hoping to expedite the recovery process for trees impacted by the late January/early February freeze event should pump the brakes and wait — at least until spring. That advice is from Muhammad Shahid, assistant professor of horticulture at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). He shared tree recovery recommendations with growers during …
Sponsored Content Question: Now that we have ReMedium TI® as a therapy to treat HLB, what else can a grower do to speed recovery? Answer: Feed the trees. I know that answer is an oversimplification, but it is the correct answer. Your groves have been struggling for years because of the root damage from HLB. While growers can’t make up …
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.

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 …
