Mayors and representatives of city halls expressed concern about the economic …
By Gary England, Fred Gmitter and Manjul Dutt In 2014, most groves in Central Florida had citrus greening infection rates approaching 100%, but a Lake County grower reported that some trees in his Hamlin on Swingle blocks seemed to be relatively healthy. Some visual HLB symptoms were observed on these “surviving” trees, but they did not have the massive fall …
HLB has yet to become a major problem for Georgia’s citrus producers. Jonathan Oliver, University of Georgia assistant professor and small fruits pathologist, attributes the disease’s lack of presence in Georgia’s commercial groves to multiple factors. “It still comes down to the fact that, number one, you don’t see symptoms for a while. A lot of our trees are young,” …
By Ajia Paolillo As the season moves from winter to spring, the irrigation requirements of citrus trees change. Typically, February through May is the drier time of year in Florida with low rainfall amounts in most areas. However, during this period, the trees are actively producing leaves and flowers, setting fruit, and pumping resources to the growing fruit during cell …
The citrus disease HLB has been confirmed for the first time in the city of San Diego, California, making it the second city in San Diego County with a positive detection. (Read about the first San Diego County detection here.) The new detection was made in a residential citrus tree located in the Rancho Bernardo area of the city. The …
The American Association for the Advancement of Science (AAAS) has elected 19 University of Florida faculty to its newest class. The honor recognizes extraordinary impact and achievement across disciplines. Two of those honored, Lukasz Stelinski and Nian Wang, work at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center.

Rep. Scott Franklin (FL-18), Rep. Debbie Wasserman Schultz (FL-25) and Sen. Rick Scott (R-FL) introduced the Block Grant Assistance Act of 2023, a critical bill to ensure the U.S. Department of Agriculture (USDA) can provide needed relief to agriculture producers devastated by Hurricanes Ian and Nicole. This bill will provide the agriculture secretary needed authority to provide block grants to …
Florida agriculture took a wallop from Hurricane Ian last year. Throw in another hurricane (Nicole) and a freeze, and the disaster losses stacked up. The state’s citrus industry took a particularly hard hit. On Jan. 17, citrus industry representatives headed to Tallahassee to testify before the Florida Senate Agriculture Committee about the toll these weather events had on an already …
IMG Citrus, based in Vero Beach, Florida, has acquired J&J Fresh Produce assets. These assets, also located in Vero Beach, include a new 185,000-square-foot cold storage and packaging facility and 1,000 acres of farmland in the Delta Farms Water Control District. “This is an exciting acquisition and a key component of our growth strategy,” said Melanie Ressler, co-chief executive officer …
By Amir Rezazadeh Cover crops protect the soil from sunlight, wind and heavy rain, which enhances soil microbial populations and improves soil structure, water infiltration and root penetration. A reduction in soil crusting, erosion, runoff and nutrient leaching are additional advantages. Through improved nitrogen cycling and nutrient retention, cover crops increase soil fertility. ORGANIC MATTER SOURCECover crops offer an inexpensive …
The total Brazilian orange crop for marketing year 2022–23 is forecast at 405 million boxes (MB), a reduction of 10 MB compared to the previous season. The commercial area in the state of São Paulo and the western part of Minas Gerais should account for 305 MB, a drop of 3% from the prior year. Production from other states is …
California’s Citrus Pest and Disease Prevention Program (CPDPP) has developed a guide, Response for a Confirmed Huanglongbing Positive Detection in a Commercial Grove, to prepare growers for a finding of the disease. The guide is intended to educate growers about the California Department of Food and Agriculture’s (CDFA) huanglongbing action plan. The devastating citrus disease spread by the Asian citrus …
In the search for ways to survive citrus greening, some growers have chosen the citrus under protective screen (CUPS) system as their solution. While CUPS can be costly to construct, it has proven to effectively prevent the deadly disease. But some have asked if the structures would hold up in extreme weather and adequately protect the trees. Hurricane Ian helped …
Researchers from Brazil’s Fundecitrus participated in the 14th International Citrus Congress held in Mersin, Turkey, Nov. 6–11. The event brought together participants from public and private research institutions, as well as the production and commercial sectors of citrus. Representatives from 28 countries participated in the congress, including the United States, South Africa, Australia, Israel and several countries in Europe. Fundecitrus …
By Kelly T. Morgan, Davie Kadyampakeni and Tripti Vashisth This article reviews current University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus fertilizer recommendations and provides updated information about recently approved recommendations for secondary macronutrients and micronutrients. Citrus growers have been very concerned about fertilizer applications and nutrient management since citrus greening (huanglongbing or HLB) was found in …
Sometimes the most niche plant pathogen packs the greatest punch. Such is the case for the Florida citrus industry, which has seen a 70% decline in its orange production since the introduction of HLB in 2005. HLB is also known as citrus greening disease. The bacteria Candidatus Liberibacter asiaticus cause this disease, which spreads via a flying insect. When the …
A grant from the U.S. Department of Agriculture’s Organic Agriculture Research and Extension Initiative (OREI) is intended to advance research to help organic citrus producers fight HLB. The grant awards $2.03 million to a team of scientists from the University of Florida, Texas A&M University and The Organic Center. The Organic Center is a non-profit organization convening evidence-based science on the …
Two citrus growers recently explained the benefits to be gained from research at the Indian River Research and Education Center’s (IRREC) Millennium Block in Fort Pierce, and a scientist discussed a grapefruit study there. The IRREC is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) facility. The 20-acre block was planted in 2019 to help growers find …
Purdue University’s Kurt Ristroph has received a $1 million federal grant to develop nanocarriers as an antibiotic delivery system to help plants fend off citrus greening disease, also known as HLB. The grant is part of the 21.7 million recently awarded for HLB research from the U.S. Department of Agriculture’s National Institute of Food and Agriculture. “The mixing technology we’re …
The focus of citrus breeding at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) differs for fruit produced for the juice market vs. fruit for the fresh market.
