The quest for long-term solutions to HLB is well underway. Technology like CRISPR is being developed to introduce tolerance or resistance to HLB. Conventional breeding also is seeking rootstocks and varieties that can resist the disease. In the meantime, growers are reminded to utilize available tools that help trees remain productive in an HLB environment. During the August Citrus & …
By Frank Giles Last year’s citrus season was marred by continuing production declines from HLB and hurricanes. The combined effect of both dropped the final all-orange output to 15.8 million boxes. Certainly, the numbers reflected the dire situation the industry found itself in after the storms. But after last year’s harvest, growers were given clearance to utilize new trunk-injection therapies …
Matthew Machata grew up in Polk County on the family’s citrus farm, Rolling Meadows Ranch Groves in Lake Wales, Florida. After he graduated high school, he joined the Marine Corps and served two tours in Iraq. He then attended Auburn University, where he earned a degree in aerospace engineering. At the time, his plans didn’t include farming, but that changed …
The January issue of Citrus Industry magazine rings in the new year with positive news! Find out how one Florida grower is producing up to 500 boxes per acre. Matt Machata tells how he rehabilitated his family’s groves in Lake Wales. He shares the details of his dry fertilizer and foliar application schedules. Attention to nutrition, irrigation and soil health …
By Tripti Vashisth, Taylor Livingston and Jamie Burrow Canopy density is one of the most effective measurements to assess tree health of HLB-affected trees. Canopy density accurately distinguished between high and low fruit-producing trees in field trials, whereas CLas Ct value has been found to not be correlated with fruit yield. Many new tools such as nutrient management guidelines, plant …
A variety of treatments Florida citrus growers are using for HLB have so far produced mixed results, according to observations reported by Highlands County Citrus Growers Association (HCCGA) President Aaron Nelson. In a recent association newsletter, Nelson wrote that many are anxious to see harvest data showing what effects the treatments have had over the past year. The treatments he …
By Michael Rogers Much has been discussed recently about the promise and potential of utilizing CRISPR technology to create HLB-resistant trees for Florida’s citrus growers. The primary objective in citrus gene editing is to develop new varieties that are resistant to HLB disease while remaining non-transgenic. To achieve this goal, researchers make alterations to or eliminate specific genes within the …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has been awarded five federal grants totaling more than $5 million to control HLB. The grants are from the U.S. Department of Agriculture’s National Institute of Food and Agriculture (NIFA). HLB is caused by the bacterium Candidatus Liberibacter asiaticus (CLas). The Asian citrus psyllid can transmit CLas into a …
The U.S. Department of Agriculture’s National Institute of Food and Agriculture (USDA NIFA) has invested more than $25 million in 11 projects as part of the Emergency Citrus Disease Research & Extension program. This program brings the nation’s top scientists together with citrus industry representatives to find scientifically sound solutions that combat and prevent citrus greening (HLB) at the farm level. Some of this …
The bad news is that severe weather warnings caused the annual citrus crop luncheon to be cancelled at Putnam Ranch in Zolfo Springs, Florida. The good news is that the Florida citrus crop forecast is up in all categories. Bill Curtis, agricultural statistics administrator with the Florida Department of Agriculture and Consumer Services, presented the U.S. Department of Agriculture’s (USDA) …
In the nearly two decades that huanglongbing (HLB) has plagued Florida citrus groves, about $1 billion has been spent in the search for solutions. A lot of great scientists in Florida and around the world have worked on the problem, and a silver bullet, if there is one to be found, has been elusive. Researchers, along with growers, have developed …
Trunk injection of oxytetracycline (OTC) is giving growers hope for the future of the Florida citrus industry. Many are optimistic the new therapy will help improve both fruit quality and quantity. The key will be whether fruit holds on the trees until harvest time. The October issue of Citrus Industry magazine provides the latest information on OTC trunk injection from …
By Frank Giles and Tacy Callies The Citrus & Specialty Crop Expo hosted two citrus educational sessions during the Aug. 16–17 event held at the Florida State Fairgrounds in Tampa. The sessions included both long-term research aimed at delivering trees resistant to HLB as well as what growers can do today to help mitigate the effects of the disease in …
Trunk injection for HLB, diplodia stem-end rot (diplodia SER) and citrus under protective screen (CUPS) were among topics addressed at the recent Citrus Packinghouse Day. The event took place at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC). TRUNK INJECTION FOR HLBTrunk injection of oxytetracycline (OTC) increases tree health, fruit quality …
With the trunk-injection season winding down in Florida groves, growers anxiously await to see positive results in HLB-infected trees. Two oxytetracycline (OTC) products have been approved for use in Florida citrus as HLB treatments. A third OTC formulation expects Environmental Protection Agency approval soon. Trunk-injection treatments are the focus of the latest All In For Citrus podcast. Michael Rogers, director …
By Jamie D. Burrow and Ruth Borger The Citrus & Specialty Crop Expo has always been a time for the industry to gather, learn and reminiscence. During the Expo at the Florida State Fairgrounds in Tampa on Aug. 16–17, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Extension booth is in a new location near the …
The Citrus Research and Development Foundation (CRDF) board of directors meeting in July focused largely on the use of oxytetracycline (OTC) as an HLB treatment in citrus. The board considered projects testing it in combination with other antimicrobial compounds or as a standalone treatment. Trunk injection of OTC has given the Florida citrus industry hope that it might be a …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus researchers and Extension staff will provide multiple educational programs at the Citrus & Specialty Crop Expo Aug. 16–17. The event will be held at a new location this year — the Florida State Fairgrounds in Tampa. Attendance is free to growers, but registration is required. UF faculty and staff …
The final U.S. Department of Agriculture National Agricultural Statistics Service (USDA NASS) citrus forecast for the 2022–23 season, issued July 12, has several changes from the June forecast. FLORIDAFlorida’s all-orange forecast rose approximately 1% to 15.85 million boxes, up 100,000 boxes from June. The full increase is in the Valencia orange forecast, which rose to 9.7 million boxes. Florida’s all-grapefruit …
While it remains to be seen if trunk injection of oxytetracycline hydrochloride (OTC-HCl) is a game changer in the fight against HLB, it certainly has intensified the conversation about the potential for antimicrobial treatments. There are literally hundreds of materials that might be effective at reducing the HLB bacteria in trees, but it has been a slow process to screen …
