Phil Stansly, University of Florida Institute of Food and Agricultural Sciences entomologist, discusses alternatives to imidacloprid for helping to control HLB-spreading Asian citrus psyllids (ACP). “Imidacloprid of course is typical of the neonicotinoids that we’ve been using as soil applications to protect young trees,” Stansly says. “We’ve seen and the growers have seen, too, that soil applications of systemic insecticides …
Sebring grower and grove manager Marvin Kahn, one of two inducted into the Florida Citrus Hall of Fame on March 9, says the industry will survive greening disease, or HLB. “I’m sure that we’ve got a real handicap now with this greening disease,” Kahn says. And no doubt we could have other diseases even following it. But with a real …
Several citrus growers and production managers offered input on future HLB research at a meeting on Feb. 15 at the Citrus Research and Education Center in Lake Alfred. The growers shared their thoughts with members of the Citrus Research and Development Foundation’s Research Management Committee (CRDF-RMC). David Howard, CRDF-RMC chairman, provides an overview of the approximately three-hour session called specifically …
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 Throughout the Citrus Research and Education Center’s (CREC) 100-year history, the collective efforts of its faculty and staff have supported Florida citrus growers in myriad …
Growers shared their concerns about numerous Hurricane Irma issues in a grower forum Friday in Arcadia. Multi-county citrus Extension agent Steve Futch summarizes the discussions. Futch says there was talk about potential disaster relief for growers and crop insurance. There was some discussion about whether there was enough damage to receive crop insurance payments. “I think the consensus was that …
Echoing comments from growers in some citrus-growing regions in southern Florida, Highlands County citrus Extension agent Laurie Hurner says Highlands County appears to have more fruit and better tree health this year. “It’s interesting. You drive up and down Highway 27, and there is a lot more fruit out there, I think,” says Hurner, who is also the Highlands County …
The California Citrus Research Board (CRB) hosted live Asian citrus psyllid (ACP) fogging demonstrations in April. The purpose was to show the viability of controlling the spread of ACP by fogging shipments of citrus on the truck, as close to the harvested field as possible. Spencer Walse, CRB research scientist specializing in chemical applications in agriculture, carried out the demonstrations. He is based at …
Wauchula citrus grower and orange grove salesman Kenny Sanders was one of the growers sharing experiences at a recent grower roundtable meeting in Wauchula. Sanders tells why he attends the meetings and discusses several practices aimed at coping with HLB. “This is very interesting,” Sanders says of the roundtable meetings. “We hear from the growers ourselves, and today we learned …
By Jim Graham and Kelly Morgan Huanglongbing (HLB), greening and yellow shoot are names for the most devastating citrus disease in the world. Symptoms of HLB include a distinctive chlorotic mottle on fully expanded leaves. Infected shoots are stunted, and branches gradually die back as the symptoms appear in other sectors of the tree canopy. HLB reduces fruit size, weight …
University of Florida (UF) researcher Kelly Morgan discusses a study of how citrus growers are adjusting irrigation water pH levels, and what pH levels seem to work best. The acid level of citrus irrigation water has become an important consideration since HLB was discovered in Florida groves in 2005. “Jim Graham (a fellow UF researcher) has been conducting a survey …
Soon after Florida’s citrus industry realized it couldn’t eradicate HLB, researchers and growers put a huge emphasis on controlling the Asian citrus psyllids that spread the disease. Most still agree that psyllid control remains essential in the short term to survive HLB. But many are now questioning the long-term economic sustainability of massive levels of psyllid control. Such questioning took …
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 …
University of Florida researcher Jude Grosser recently discussed a broad range of research aimed at mitigating the effects of HLB during an OJ Break in Sebring. Among topics he covered are the possibility of windbreaks that kill HLB-spreading Asian citrus psyllids, and progress on trees that are HLB resistant or tolerant. Regarding psyllid-killing windbreaks, he says, “We do have a …
By Tacy Callies Callie Walker comes from a long line of Florida farmers. In 1875, her family set up homestead in Alva. Her father, uncles, grandfather and great-grandfather have been involved in a diversity of agricultural fields including citrus, cattle, sugar cane, vegetables and row crops. “My dad and his three brothers still run the family operation — citrus and …
Rhuanito “Johnny” Ferrarezi, a new citrus horticulture scientist at the Indian River Research and Education Center near Fort Pierce, discusses his research plans. “I’m going to be focusing on irrigation, plant nutrition and cultural practices to improve our current practices and try to maximize plant survival under greening conditions,” he says. Most of his attention will be on Indian River …
By Marcos Fava Neves We are normally threatened by natural storms hitting the orange juice chain, some of them hurricanes. Matthew was the last one, but fortunately it remained off the coast of Florida rather than directly hitting the orange-production area. However, the orange juice chain is facing a storm — an economic hurricane that is complicating supply and demand. …
By Taylor Hillman The flood of technologies hitting the market hasn’t slowed since developers turned their attention to precision agriculture. One thing that remains common among these technologies is the use of data, which has been previously ignored or unmonitored. Now, developers are focusing on algorithms and patterns in data sets that are collected during farming practices that will improve …
Communicating about genetic engineering as a partial solution to greening disease (HLB) was the topic of a recent OJ break in Sebring. Florida Department of Citrus (FDOC) Executive Director Shannon Shepp participated in the meeting and discusses the FDOC’s role in telling consumers about greening. “We’re very clear on the fact that biotechnology research is happening … We know that …
Grower Joe Davis Jr., a panelist at a Peace River Valley Citrus Growers Association gathering Thursday, says he expects a Florida orange crop of 61 to 70 million boxes this season. Last season’s Florida orange crop was 81.5 million boxes. “Our groves are down,” Davis says. “We’re guessing that earlies and mids will probably be down about 10 percent, and …
“I don’t think there were any real surprises in the report today,” Indian River area grower and packer Cody Estes says in response to the U.S. Department of Agriculture’s report that Florida citrus acreage tumbled 4 percent. Florida acreage is now at 480,121, the lowest number since tracking began in 1966. “Hopefully with the anti-microbial treatments that are going on, …
