By Yiannis Ampatzidis Artificial intelligence (AI) is a promising area in computer science, automation, robotics and agriculture. AI describes the capability of a machine to imitate intelligent human behavior and mimic cognitive functions such as learning and problem-solving. Machine learning, which is an application of AI, is based on the idea that a machine, such as a computer or microcontroller, …
By Juanita Popenoe 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. Pesticides are only one part of a comprehensive integrated pest management (IPM) plan and should be used strategically. What happens …
Florida growers are being asked to take a survey on the use of cover crops and reflective mulch in citrus production. These systems are being investigated as potential means to improve soil health and reduce pest pressure from Asian citrus psyllids, which transmit the destructive citrus disease HLB. The survey is being conducted by researchers with the University of Florida Institute …
As temperatures increase across Florida, so does the risk for huanglongbing (HLB) disease, known as citrus greening. While the southern and central portions of the state remain vulnerable to HLB and Asian citrus psyllids (ACP) that spread the disease, growers in North Florida and South Georgia have so far been spared. But Xavier Martini, University of Florida entomologist at the …
“We’ve come a long way in the time that we’ve had HLB here in Florida,” says Michael Rogers. The director of the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Citrus Research and Education Center says early HLB research “covered a wide range of topics.” Now, however, “We’re really narrowing down things that are of use to growers …
Two Florida citrus grower associations expressed disappointment over the recent Florida Department of Agriculture and Consumer Services’ (FDACS) decision to deny the use of the pesticide aldicarb in Florida citrus. “We are frustrated in the decision as we believe aldicarb will provide a powerful tool in the fight against citrus greening and can be used safely,” said Florida Citrus Mutual …
The Citrus Research and Development Foundation (CRDF) received 59 proposals for funding of projects in response to the organization’s recent request for proposals (RFP). “This is the best RFP we’ve ever done since I’ve been here,” said CRDF Chief Operating Officer Rick Dantzler. The deadline for submitting proposals was April 26, a day before the CRDF’s board of directors …
By Owen “Sonny” Conner The two greatest challenges of the last 20 years, for me as a citrus grower, have been HLB and foreign competition depressing prices. Citrus growers had never faced a disease threat even approaching the devastating effects HLB has had on the industry. It was the industry killer we all feared would one day raise its ugly …
Two growers expressed different views about the recent decision to deny the use of the pesticide aldicarb in Florida citrus. The denial was made by the Florida Department of Agriculture and Consumer Services (FDACS). One termed the decision “disappointing.” The other referred to it as a “a blessing.” “It is disappointing to lose any tool that would strengthen our existing …
Preventing HLB infection in newly planted citrus trees with individual protective covers (IPCs) can improve productivity and fruit quality. Thus far, IPCs have kept young citrus trees free of HLB in research plots. “Once you plant a tree, if it’s not protected, it’s exposed to HLB infection from day one,” says Fernando Alferez, an assistant professor at the University of …
The Florida Department of Agriculture and Consumer Services (FDACS) denied AgLogic Chemical LLC’s state pesticide registration application for the pesticide aldicarb on citrus crops in the state of Florida. Aldicarb is an N-methyl carbamate insecticide primarily used as a nematicide. Responsible for the worst known outbreak of pesticide poisoning in North America, aldicarb is one of 28 active pesticide ingredients …
University of Florida Institute of Food and Agricultural Sciences entomologist Lauren Diepenbrock provided an update on lebbeck mealybug during the 2021 Florida Citrus Growers’ Institute. The pest, first found in Florida commercial citrus in 2019, feeds on and damages citrus, causing up to 70% fruit drop in heavily infested groves. According to Diepenbrock, damaged fruit will not be marketable for …
Nematologist Larry Duncan discussed efforts to control the root pests sting nematode and Diaprepes root weevil in his presentation during the virtual April 6 Florida Citrus Growers’ Institute. Duncan works at the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Citrus Research and Education Center. The sting nematode and Diaprepes are especially concerning in the age of HLB, …
Citrus under protective screen (CUPS) does a great job of safeguarding trees from the HLB-spreading Asian citrus psyllids. However, CUPS does not protect trees from all other pests. The benefits of eliminating HLB are immediate and include rapid, normal tree growth, higher yields of premium-quality fruit and less fruit drop. Since CUPS is a relatively new system, researchers are still …
By Christopher Vincent, Anirban Guha, Joon Hyuk Suh and Yu Wang It may surprise you to learn that citrus trees can get too much sunshine in the Sunshine State. Manipulating the light environment around a plant can have several surprising benefits. Shade can suppress the HLB cycle and enhance citrus health and yield. Overall, a mildly shaded citrus plant is …
The San Joaquin Valley ACP/HLB Area-Wide Task Force strongly recommends citrus growers in Kern County, California, to add an Asian citrus psyllid (ACP)-effective material to their pre-bloom or spring foliar treatments. Since ACP build populations on the young leaf flush, the sooner growers spray, the better. Fortunately, this timing coincides with pre-bloom treatments for katydid, worms, thrips and other pests. …
The annual Florida Citrus Growers’ Institute, hosted by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension, will be held on April 6. The event will be delivered via a Zoom webinar from 8:30 a.m. to 12:00 p.m. “We hope to reach a broad audience despite the limits imposed on us because of the COVID-19 pandemic,” said Chris …
Michael Rogers discusses three popular upcoming citrus grower educational meetings: Florida Citrus Growers’ Institute in April, the Florida Citrus Show in May, and Citrus Expo in August. Rogers is director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in Lake Alfred. UF/IFAS is the primary planner of educational presentations at all …
By Sylvia Willis, Amy Vu and Jamie Ellis When people think of Florida, the first thing that comes to mind is Fresh From Florida oranges. Florida accounts for 44 percent of total U.S. citrus production. Citrus, like many other fruits, vegetables and specialty crops, requires certain inputs to grow and produce fruit. But how are pollinators and the production of …
March’s All In For Citrus podcast brings news of in-person events, details on controlling the vector of HLB disease, as well as potential changes to nutrient and water management recommendations. Citrus Research and Education Center Director Michael Rogers begins the episode discussing several upcoming events for growers. On April 6, the Florida Citrus Growers’ Institute will return as a virtual …
