Invaio Sciences, Inc. recently announced an agreement with Brazil’s Fundecitrus to evaluate the use of a natural peptide to control HLB in Brazil. The agreement will leverage Fundecitrus’ expertise in citrus grove and pest management to evaluate application details of the novel peptide maSAMP in locally relevant conditions. The peptide was developed by Hailing Jin of the University of California Riverside. …
Shifting consumer trends have helped dictate which varieties are most popular among California citrus growers. Bruce Babcock, professor in the School of Public Policy at University of California, Riverside, explained that over the past 15 years or so, there have been some notable changes in California citrus acreage. “What we’ve seen is just explosive growth in acreage devoted to mandarins. …
Florida and California specialty crop growers recently gathered for a virtual discussion presented by J.L. Farmakis, Inc. to talk about issues unique to their crops and regions. Citrus grower Lee Jones with Cross Covered Caretaking represented the Sunshine State. He shared some of the struggles and successes of growing citrus in Florida. Jones says one of the biggest challenges he …
A group of scientists working in California, New York and Washington has found that Lisbon lemon trees had less of a molecular response than Washington navel orange trees to the pathogen that causes HLB. That pathogen is Candidatus Liberibacter asiaticus (CLas). In part, this might be because leaves of infected lemons tended to accumulate micronutrients, which led to less of …
New research affirms a unique stable antimicrobial peptide (SAMP) found in an Australian plant can destroy HLB and help prevent infection. Hailing Jin, University of California Riverisde geneticist who led the research, shared the exciting discovery during the 2021 Florida Citrus Show. The naturally occurring peptide is found in HLB-tolerant citrus relatives, such as the Australian finger lime. The peptide …
Reductions in the projected Florida grapefruit and tangerine/tangelo crops were the only changes in the May 12 U.S. Department of Agriculture (USDA) citrus crop forecast. USDA’s National Agricultural Statistics Service (NASS) reduced Florida’s grapefruit crop projection by 2%, to 4.2 million boxes, down from 4.3 million boxes in April. The total 100,000-box reduction was in red grapefruit, which dipped to …
California Attorney General Rob Bonta on April 29 applauded a decision by the Ninth Circuit Court of Appeals requiring the U.S. Environmental Protection Agency (EPA) to make a required safety finding for chlorpyrifos residues detected on food. Chlorpyrifos is a widely used agricultural pesticide approved for use on more than 80 food crops. The court decision orders the EPA to …
University of Maryland virologist Anne Simon and the company she founded, Silvec Biologics, have successfully vaccinated laboratory hosts against citrus tristeza virus (CTV). They are now focusing on HLB, also called citrus greening. The vaccination induces trees to produce their own therapeutic agents. Silvec’s vaccination concept is based on the discovery of a novel infectious RNA that the company calls …
Florida’s Valencia orange crop projection tumbled 12% in the April 9 U.S. Department of Agriculture (USDA) crop forecast, to 29 million boxes from 33 million boxes in March. The USDA added 200,000 boxes, or 1%, to Florida’s non-Valencia tally, bringing non-Valencias to 22.7 million boxes. In total, Florida oranges dipped to 51.7 million boxes, down 7% from March’s 55.5 million …
The response rate in Florida has been lower than expected in an effort to assess the impact of the COVID-19 pandemic on food and agricultural systems and to develop strategies for coping with future crises. Consequently, those involved in Florida agriculture are being asked to respond by April 11 to a survey about the pandemic’s impact. “We’re seeking food supply …
A presentation at the recent Citrus Pest & Disease Prevention Committee State of the Central Valley meeting in California highlighted the importance of scouting for Asian citrus psyllids (ACP) in groves. Scouting becomes even more critical as the risk of ACP and HLB, the disease the insect transmits to trees, rises. The presenter, University of California (UC) Riverside Extension Specialist …
This year’s La Niña weather event is bringing up bad memories for California citrus growers. The industry suffered during the drought years of 2012 to 2016 and the specter of a repeated drought looms with every dry day. The California Natural Resources Agency addressed drought fears in a recent report prepared by Jeanine Jones, interstate resources manager for the California …
A coalition of groups on March 25 sued the Environmental Protection Agency (EPA) for approving spraying of streptomycin on citrus trees to prevent or treat HLB or citrus canker. The groups claimed that the practice of spraying antibiotics on trees has been ineffective in combating the diseases and can drive antibiotic resistance in bacteria, which can threaten human health. The …
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. …
Psyllid sprays have been a point of contention for Florida citrus growers. Under endemic HLB conditions, high psyllid control costs have cut into the grower’s bottom line, which has already been hit by reduced production. So, what is the right time to spray and how can a grower remain sustainable and profitable? Lukasz Stelinski, University of Florida professor of entomology …
Bayer has introduced Vynyty Citrus®, its latest biological and pheromone-based crop protection product to control pests on citrus farms. Vynyty Citrus®, a container with an active liquid inside, does not generate resistance or residues in harvests or in the environment, according to Bayer. It is the first such product on the market that is formulated with pheromones and natural pyrethrum …
By targeting Asian citrus psyllids on an area-wide scale and focusing on several individual properties simultaneously, growers can minimize psyllid movement between groves, reduce HLB transmission and maintain citrus production at a profitable level. Generally, most psyllid sprays are applied on a calendar or threshold basis, resulting in high-spray frequencies and associated costs. Because of the Asian citrus psyllid’s high …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus researchers are collaborating on ground-breaking research projects to fight against HLB. They are working with researchers at the University of California-Riverside (UC-Riverside), Texas A&M and Washington State University on a project to field-test new citrus cultivars for tolerance or resistance to HLB. The research is funded by the U.S. …
