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 …
By Marcelo Pedreira Miranda, Haroldo Xavier Linhares Volpe, Renato Beozzo Bassanezi, Ivaldo Sala and Juliano Ayres Huanglongbing (HLB), or citrus greening, is a notable threat to the citrus industry worldwide and was reported in the central region of São Paulo state (SPS) in Brazil in 2004. HLB then spread quickly throughout SPS, requiring the citrus industry to adapt rapidly to …
A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher has found a material that can be used to silence essential genes within Asian citrus psyllids and in the HLB-causing bacterial pathogen that the psyllids spread. The material is 2’-deoxy-2’-flouro-d-arabinonucleic acid antisense oligonucleotides (FANA ASO), small-sized single-stranded nucleic acids. The discovery was made by Kirsten Pelz-Stelinski, an associate …
Researchers at the California Data Analysis and Tactical Operations Center (DATOC) have analyzed Asian citrus psyllid (ACP) trapping data along major transportation routes before and after tarping regulations for bulk citrus shipments were enacted. The purpose was to determine the effectiveness of the policy. DATOC is an independent group of scientists sponsored by the Citrus Research Board and the California …
By Lauren Diepenbrock While scale and mealybug pests commonly found in citrus have historically been controlled by predators and parasites, management advice for this group of insects is often requested. There are likely several underlying factors to these insects becoming more frequently encountered. This includes changes in insecticide management practices, changes in nutritional management, and increased scouting due to the …
By Emilie Demard and Jawwad Qureshi Managing the Asian citrus psyllid (ACP), a vector of huanglongbing (HLB), is critical for reducing disease incidence and improving tree health. Growing citrus under screened structures, referred to as citrus under protective screen (CUPS), protects trees from ACP and HLB. CUPS provides an opportunity to produce premium-quality fresh fruit by preventing psyllids and HLB …
The Australian finger lime, a citrus relative, could be a new specialty crop for Florida citrus growers. Traditionally, finger limes have remained rare in the United States, grown few and far between. However, the fruit’s unique tolerance to HLB is becoming increasingly attractive to Florida growers. Manjul Dutt, research assistant scientist at the University of Florida Institute of Food and …
Fertilizers help crops reach maximum yields while fungicides prevent diseases. But what if there were products available that could further enhance the fruiting qualities all growers hope to achieve every season? IMPROVED FRUIT PRODUCTIONIf growers can increase the level of flowering hormones in their crops, this will allow for a better fertilization process that will generate improved fruit set and …
Citrus Research and Development Foundation (CRDF) Chief Operating Officer Rick Dantzler on Feb. 23 detailed CRDF spending on efforts to solve HLB. According to Dantzler, the Florida-based organization spent $140.7 million between its formation in 2009 and 2020. The vast majority of CRDF’s focus has been on HLB. Dantzler’s report came moments after University of Florida (UF) Institute of Food …
