Ramdas Kanissery, speaking at the Citrus & Specialty Crop Expo, offered what he called an important strategy to prevent weed outbreaks in groves: “Never let ’em germinate.” Growers can keep weeds from germinating with pre-emergent herbicide programs, said the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor of weed science. He works at the Southwest Florida …
Editor’s note: This Q&A was conducted prior to Hurricane Ian striking Florida. After the storm, Matt Joyner said that Florida Citrus Mutual is working with growers in the recovery process and collecting information to aid in any potential requests for assistance. Matt Joyner started with Florida Citrus Mutual (FCM) in December of 2018 as director of government relations. In April …
By Michelle Danyluk In terms of food safety, not all standing water in a field is considered floodwater. Flooding is considered the flowing or overflowing of a field from open bodies of water outside the food crop producer’s control. Events that lead to pooled water or excess standing water in a field, such as rain or a problem with an …
The Citrus Research and Development Foundation (CRDF) was able to hold its September board of directors meeting just prior to Hurricane Ian. During the meeting, CRDF awarded funding for Cycle Four of the Citrus Research and Field Trial (CRAFT) program. This will allow for another round of investments in grower-led research projects. “Kristen Carlson, Tamara Wood, the Technical Working Group …
How well reflective mulch, kaolin clay and individual protective covers (IPCs) hold up to HLB, canker and greasy spot diseases was researcher Megan Dewdney’s topic at the 2022 Citrus & Specialty Crop Expo. Dewdney is a University of Florida Institute of Food and Agricultural Sciences associate professor of plant pathology at the Citrus Research and Education Center. The research project …
By Rick Lusher The University of Florida Institute of Food and Agricultural Sciences Florida Automated Weather Network (FAWN) is a great resource for citrus growers. Its mission is to leverage timely, reliable and accurate weather data in support of effective agricultural decision-making and stewardship of natural, human and fiscal resources. In addition to weather information accessible in multiple databases, there …
By Christa Court Disaster events, such as extreme weather events (hurricanes, floods, droughts, etc.), have always been and will continue to be a threat for growers. Impacts to a citrus grove might include production losses associated with fruit drop from surviving trees and asset damages to buildings, machinery/equipment, irrigation systems and destroyed trees. Producers might also incur increased costs for …
The September issue of Citrus Industry magazine centers on two topics: citrus under protective screen (CUPS) research and a wrap-up from the Citrus & Specialty Crop Expo. Three articles cover the latest CUPS findings from the University of Florida Institute of Food and Agricultural Sciences. An article by Arnold Schumann and his colleagues includes a summary of seven seasons of …
Entomologist Lauren Diepenbrock discussed control of three pests — lebbeck mealybug, Bulimulus sporadicus snails and diaprepes root weevils — at the recent Citrus & Specialty Crop Expo. The University of Florida Institute of Food and Agricultural Sciences researcher described the mealybug and snails as “new pest challenges” and diaprepes as the resurgence of an old pest. LEBBECK MEALYBUGLebbeck mealybug was …
By Sandra M. Guzmán In Florida citrus, black fabric mulch groundcovers have been used for the control of the invasive Diaprepes abbreviatus (root weevil). However, these groundcovers can also serve as a best management practice (BMP) to optimize tree water uptake and maintain nutrients around the root system. A three-year University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) …
By Yiannis Ampatzidis and Sandra M. Guzmán Pests and diseases, nutrient deficiencies, tree stress from environmental conditions and other factors can be overwhelming. The arrival of sensors and small unmanned aerial vehicles (UAVs) make it possible to gather large amounts of data to assess risk factors and estimate possible crop performance scenarios based on the availability of resources. At the …
Some species of snails in Florida groves, normally seen on irrigation emitters and tree trunks, have recently “taken up residency in young citrus trees,” University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension agents Chris Oswalt and Ajia Paolillo reported. Here’s a summary of what the agents wrote in a recent UF/IFAS Central Florida citrus Extension newsletter: Once …
A little more than 20 inches of rain has fallen on Dale Murden’s Texas grapefruit grove in 2022 — “about average for the year,” he says. But the majority of Texas is in severe drought, and that poses problems for Murden and other Texas growers, especially for the future. “We just are not seeing any rain or significant inflows in …
By Amir Rezazadeh Saline soil and water damage many citrus groves in Florida. In general, when the dissolved salt concentration in soil or water increases, it is referred to as “saline” soil or water. But how much increase in salt concentration makes soil or water saline? Citrus plants’ major reactions to excessive salt in the soil or water are reduced …
By Tripti Vashisth and Mary Sutton Citrus trees affected by huanglongbing (HLB) consistently have small fruit and low fruit numbers at harvest. The low fruit numbers are largely attributed to the increased rates of preharvest fruit drop that accompany HLB. Small fruit is more likely to drop during this preharvest period, suggesting a link between fruit size and retention. To …
Turkey is forecast to produce 249,000 metric tons (MT) of grapefruit in 2021–22, up 5% over the prior year, the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA/FAS) reported. The increased production is due to better yields resulting from favorable weather conditions in the Mediterranean growing region, USDA/FAS stated in its semi-annual report on Turkish citrus. Improved yields have allowed …
There 17 essential elements that plants need to grow. Three of those elements come to plants via water and the atmosphere. The 14 other elements come from fertilizer applications. Almost all of those are dependent on soil pH to determine how well they are picked up by plants’ root systems. Getting the soil pH just right was discussed in the …
There is a growing trend of South African mandarin growers aggressively establishing new orchards under netting, the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA/FAS) recently reported. The practice has improved water efficiency, yields and the overall quality of fruit, USDA/FAS says in its semi-annual South Africa citrus report. USDA/FAS says the production of tangerines/mandarins in South Africa is anticipated …
The sweltering heat being felt across the Southeast has done little to dampen the optimism shared by one citrus grower who believes this year’s crop is “very promising.” Kim Jones, who owns a citrus packing facility in Monticello, Florida, and is part-owner of a similar facility in Tifton, Georgia, discusses the state of this year’s crop in North Florida and …
This summer has been a steamy one with some Florida locations breaking record highs. The latest episode of the All In For Citrus podcast took up the hot topic with Amir Rezazadeh, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) fruit and field crops Extension agent. He addressed how heat can affect citrus trees and people working …
