Editor’s note: This article is part of the special coverage on the 100th Anniversary of the UF/IFAS Citrus Research and Education Center, found in the October 2017 issue of Citrus Industry magazine. By Tom Nordlie Although it’s difficult to predict future events, directors of the University of Florida Institute of Food and Agricultural Sciences Citrus Research and Education Center (CREC) …
Research shows that abandoned citrus groves can harbor unwanted pests and citrus diseases. Therefore, the Florida Department of Agriculture and Consumer Services (FDACS) Bureau of Pest Eradication and Control is raising more awareness about its Abandoned Grove Initiative to help destroy those safe havens for deadly pests. Callie Walker, chief of the FDACS Bureau of Pest Eradication and Control, says …
As in previous years, orange shipments to Korea must be free of Fuller rose beetle (FRB) and California red scale (CRS). Growers desiring to qualify oranges for export to South Korea must comply with the FRB protocol during the 2017-2018 shipping season. Growers are required to implement the following measures for FRB control on oranges: 1. Skirt-prune trees to prevent …
Biocontrol of Asian citrus psyllids can be improved by controlling ants. By Kelsey Schall and Mark Hoddle More than a decade of battle with the Asian citrus psyllid (ACP)-huanglongbing (HLB) complex has drained the vigor from Florida’s citrus industry, costing billions in disease management and production losses. With HLB established in parts of urban Southern California, the second largest citrus …
By Larry Duncan Citrus growers are recognized as early adopters of practices that enhance the biological control of arthropod pests. For more than a century, tactics such as the exploration and importation of predators and parasitoids or the reduced use of insecticides that disrupt biological control were increasingly employed against pests in the tree canopy. Beginning in the early 1990s, …
By Ernie Neff Gulf citrus growers had a CHMA (citrus health management area) before CHMAs were popular — even before they were called CHMAs! Phil Stansly, University of Florida (UF) entomology professor, is among those credited with organizing Florida’s first psyllid- and HLB-fighting CHMA. Others recognized for the achievement include Gulf Citrus Growers Association (GCGA), Florida Cooperative Extension Service and …
by Robin Koestoyo, UF/IFAS koestoyo@ufl.edu Garima Kakkar is joining the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) to help the state fight invasive pests. Kakkar, an expert in invasive insects, is a multi-county Extension agent based in St. Lucie County. Kakkar has a diverse range of experience in managing pest insects, and will now serve growers in the …
Improved training and minimum age requirements will help protect people and the environment. The U.S. Environmental Protection Agency (EPA) is finalizing standards for applicators who apply restricted-use pesticides that are not available for purchase by the general public, and require special handling. “We are committed to keeping our communities safe, protecting our environment and protecting workers and their families,” said …
Citrus Research and Development Foundation (CRDF) Chief Operations Officer Harold Browning provides an update on a major five-year HLB project that CRDF is managing. “It’s (NuPsyllid) a project that started in 2012, involving a team of scientists from all over the country … And the goal is to build and release into the field the psyllid that has less capacity …
University of Florida entomologist Phil Stansly discusses the use of dormant sprays for HLB-spreading psyllids. He also addresses the fact that psyllid populations are often higher on grove perimeters — the so-called “edge effect.” Stansly says the next coordinated grower spray for psyllids in the Gulf citrus-growing region will be a dormant spray. “The trees are dormant now and that’s …
Gardinier Florida Citrus General Manager Lee Jones, one of several attending a Gulf Citrus Health Management Area Workshop on November 15 in Immokalee, wanted to share a message with fellow growers. The message: Don’t reduce efforts to control HLB-spreading Asian citrus psyllids. “Everybody’s groves this year are looking a little better,” Jones told Citrus Industry magazine immediately after the seminar. …
The citrus black spot (CBS) that emerged in Florida in 2010 apparently remains confined to Collier and Hendry counties, except for a single find in Polk County in 2013. “There’s a quarantine within those two counties (Collier and Hendry),” University of Florida researcher Jeff Rollins said in a Citrus Expo presentation. “The quarantine extends a little bit into Lee County, …
Citrus grower Paul Fabry discusses grove practices that led to a huge increase in production in a newly acquired Basinger grove in just a few seasons. The grove has approximately 750 net acres. “Two years ago when we first got the grove, it was in a shape that needed some renovation and I was advised by several prominent industry leaders …
Citrus growers sometimes ask University of Florida entomologist Phil Stansly why they should continue to spray for HLB-spreading psyllids when trees are already infected with the disease. Stansly answered that question at Citrus Expo in August. “There are two issues with HLB,” Stansly says in this interview with Tacy Callies summarizing his Expo presentation. “One is incidence. In other words, …
Research on HLB-tolerant trees and better citrus varieties is being conducted in Gainesville, outside the Florida citrus belt. University of Florida scientist Jose Chaparro discusses the work. “In Gainesville we have essentially the youngest citrus breeding program in Florida,” Chaparro says. “In the future, we hope to be able to provide both HLB and canker resistance in our selections.” Such …
A Citrus Research and Development Foundation (CRDF) Research Management Committee meeting was called on June 29, 2016, to discuss post-bloom fruit drop (PFD) caused by Colletotricum spp. in Florida. In this meeting, it was suggested that there is an opportunity to retrospectively investigate PFD management strategies from 2016 to determine if grower treatment programs led to variable results. A survey …
Tom Stopyra, technical crop advisor for The Packers of Indian River, shares experiences with HLB and offers opinions on numerous other topics he addressed at a recent seminar in Immokalee. Regarding the record high populations of HLB-spreading psyllids throughout Florida’s citrus belt this year, Stopyra says: “We’ve never seen populations like we have this year, even though we’ve been spraying …
Populations of HLB-spreading Asian citrus psyllids have been at record levels since April, University of Florida Citrus Health Management Area (CHMA) Program Coordinator Brandon Page told growers at a recent seminar in Immokalee. Page thinks abandoned groves that aren’t sprayed and therefore harbor psyllids are part of the reason for the recent population increase. “I think we’re also seeing money …
Tom Stopyra, technical crop advisor for the Packers of Indian River, told more than 75 growers at an Immokalee seminar last week how his company gets excellent canker management utilizing a four-pronged program: “You have to control the leafminer. You have to have frequent copper sprays at a lower rate. You have to have windbreaks and sanitation, which is the …
University of Florida professor Larry Duncan presented the latest research on using entomopathogenic nematodes (EPNs) to control Diaprepes root weevil (DRW) in citrus to approximately 30 growers on June 30 at the Hardee County Extension Service office in Wauchula. The combination of HLB with DRW intrusion has created a situation that will accelerate the destruction of most infected trees. DRW …
