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 …
Grower: Don’t Cut Back on Psyllid Control
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. …

Citrus Nursery Tour Showcases New Technology
Citrific Nursery president Mathew Konrad recently gave a citrus nursery tour to show a culture process and automated nursery system that could be beneficial to the citrus industry. “I got into this industry because I felt like the industry was lacking a lot of common technologies and more sophisticated nursery operations,” said Konrad. He explained that he wanted to make …
From Planning to Planting: Establishing New Groves in the Presence of HLB
By Ute Albrecht Despite the constant threat of huanglongbing (HLB), most growers remain optimistic and are replanting citrus trees to maintain production levels necessary for sustaining the industry. The tax incentive bill under the Emergency Citrus Disease Response Act introduced in December 2015, if implemented, will help growers get back expenses associated with replanting of diseased trees immediately, instead of …
Citrus Grower: Tree Replant Incentives Are Beneficial
State and federal programs giving citrus growers incentives to replant and a state program designed to eliminate abandoned groves were discussed at a November 1 workshop in Lakeland. The program was hosted by Florida Citrus Mutual. Grower James “Hoss” Morgan, procurement director for Wm. G. Roe & Sons, Inc., likes the programs. “All three of these are very beneficial if …
Grower Gets Strong Orange Production
Bobby Mixon of Sunny South Packing Company, one of several sharing experiences at a recent grower forum in Arcadia, reported good production from a Vernia orange block. He said the block yielded 450 to 500 boxes to the acre last season, which is far above average orange yield in the HLB era. Mixon says Vernia provides “alternate production” from year …
UF/IFAS Imaging System Can Detect Citrus Greening Before Symptoms Show
By: Brad Buck GAINESVILLE, Fla. — A time-lapse polarized imaging system may help citrus growers detect citrus greening before the plant’s leaves show symptoms, which should help growers as they try to fend off the deadly disease, a new University of Florida Institute of Food and Agricultural Sciences study shows. For the new study, Won Suk “Daniel” Lee and Alireza …
New Methods for Managing Citrus Nutrition
University of Florida horticulturist Arnold Schumann recently discussed new ways growers might better manage citrus nutrition. During the Citrus Nutrition Day at the Citrus Research and Education Center, he spoke about the potential future use of a Diagnosis and Recommendation Integrated System (DRIS) that he’s working on. He also addressed the benefits and results of hydroponics in citrus nutrition management. …
UF/IFAS FAWN System Helps Growers Save Water and Money
Citrus grower James Shinn remembers days when he and his workers would rush out as early as 5 p.m. to turn water pumps on to irrigate his crops. “We had no idea when the temperature would drop, so we had to get out there early and get the water going.” Now, researchers with the University of Florida Institute of Food …
The Many Hats of Allen Morris
By Tacy Callies Having grown up in the small north Florida town of Macclenny, a farming community, Allen Morris was introduced to agriculture at an early age. His father died in a tractor accident when Morris was seven, but that didn’t deter him from wanting to earn a living in agriculture. In fact, at 14, he obtained a restricted driver’s …
Citrus Replanting Incentives in Face of HLB
More than 50 attended a November 1 workshop in Lakeland to learn about incentives to induce citrus tree replanting. Replanting is needed to replace trees lost to HLB and other problems. Kayla Nickerson of the Florida Department of Agriculture and Consumer Services (FDACS) talks about a relatively new incentive – her agency’s Citrus Grove Renovation/Re-establishment Support Program. Nickerson says, “We’re …
Managing the Health and Productivity of HLB-Affected Groves
By Tripti Vashisth In 2005, huanglongbing (HLB or citrus greening disease) was first discovered in Florida. Florida orange production changed from 242 million boxes in the pre-hurricane, pre-HLB, 2003–2004 season to 81.5 million boxes in 2015–2016. This dramatic reduction in yield is attributable to multiple causes, including a reduction in citrus acreage, citrus canker and other citrus diseases. HLB is …
Some Growers ‘Being Squeezed More than Others’ by HLB
Citrus Extension agent Steve Futch answers questions following a grower forum in Arcadia on October 27. Growers discussed production, bactericides for HLB and much more. The forum opened with one grower saying he doesn’t know how much longer he can keep going. Another reported per-acre orange production of 450 to 500 boxes in some blocks – a superb level in …
Control of Stem-End Rot of Fresh Citrus
By Mark A. Ritenour, Jiuxu Zhang and Megan M. Dewdney Decay of fresh citrus fruit is most often caused by fungal pathogens that grow and develop in the hot and wet conditions typical in Florida. While green and blue molds (Penicillium digitatum and Penicillium italicum) and sour rot (Galactomyces citri-aurantii) are the most common postharvest citrus diseases worldwide, the subtropical …
Growers to Pay Department of Citrus Historically Low Tax Rate
Citrus grower taxes supporting Florida Department of Citrus (FDOC) programs this season will be 7 cents per box for processed oranges and fresh grapefruit – the two most utilized fruits. Those historically low rates were proposed early in 2016 by 12 large Florida citrus growers and adopted by the Florida Citrus Commission (FCC) on October 26. Other per-box grower assessments …

Grower Urges Participation in UF Nutrition Trials
Central Florida citrus grower Vic Story tells why he’s participating in grower nutrition trials being conducted by University of Florida researcher Tripti Vashisth, and urges other growers to participate. “We need to look at some of the varying programs that the university has proposed in practical, out-in-the-grove situations over a period of time,” Story says. “I’m measuring these programs against …
Monitoring Plant Metabolism to Detect HLB
HLB pre-screening through analyzing plant metabolism holds potential to be a relatively inexpensive option for growers. Caroline Slupsky, professor in the Department of Nutrition and Food Science and the Department of Technology at the University of California, Davis, is looking at the metabolism of citrus trees and analyzing changes as indicators of stress and disease. Plants’ metabolic pathways change in …
Controlling HLB with Thermotherapy: What Have We Learned So Far?
By Reza Ehsani, Megan Dewdney and Evan Johnson In the last two years, many growers looked at thermotherapy as a way of keeping HLB-affected citrus trees in production until a more permanent solution could be developed. It has been shown that thermotherapy can kill HLB-causing bacteria under controlled environments. But the exact time and temperature is not known, and it …
