CRDF Addresses Plant Improvement, Budget
Citrus Research and Development Foundation (CRDF) directors recently received an update on planned rootstock field trials and discussed the organization’s budget, CRDF Chief Operating Officer Rick Dantzler reported. ROOTSTOCK TRIALSThe new rootstock trials will be overseen by CRDF’s Select Committee on Plant Improvement, which met on Oct. 22 with citrus grower John Gose as chairman. Dantzler said the field trials …
Proving COVID-19 Isn’t Foodborne
When the COVID-19 pandemic became news in the United States early this year, some consumers and others wondered if it might be spread by food or food packaging. Food scientist Michelle Danyluk says there is no epidemiological evidence that COVID-19 is spread that way. “But epidemiological evidence isn’t the same as hard science data,” she adds. Consequently, she and other …
Emerging Trunk Disorders
By Evan Johnson and Megan Dewdney The last two years have seen increasing grower questions and reports of citrus trunk disorders in Florida. Sometimes these reports are associated with sudden tree collapse. In many cases, phytophthora foot rot is initially suspected. Typically, the symptoms don’t quite match those of foot rot, and phytophthora cannot be isolated from the lesion. If …
UF/IFAS Gets $4.5M to Continue HLB Fight
Three teams of scientists from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) recently received nearly $4.5 million in U.S. Department of Agriculture (USDA) funds to study new ways to manage HLB. The funding is part of the $45 million in grants the USDA National Institute of Food and Agriculture’s Emergency Citrus Disease Research and Extension Program …
FDOC Offers 2020-21 Citrus Season Outlook
Florida Department of Citrus (FDOC) economist Marisa Zansler recently broke down the expected utilization of the 57 million boxes of oranges Florida is forecast to produce in the 2020-21 season. She also offered projections for utilization of grapefruit and specialty fruit, and made other economic projections in her outlook for the season. ORANGESAbout 96 percent of the orange crop is …
USDA Grants $45 Million for HLB Research
The U.S. Department of Agriculture’s National Institute of Food and Agriculture (USDA-NIFA) recently awarded 12 grants totaling more than $45 million for research to combat HLB. “USDA-NIFA’s Emergency Citrus Disease Research and Extension Program (ECDRE) brings the nation’s top scientists together to tackle this problem,” said Parag Chitnis, NIFA’s acting director. Following are the 12 ECDRE projects funded by USDA-NIFA …
Enhancing Soil Health With Cover Crops
By Sarah Strauss, Antonio Castellano-Hinojosa, Davie Kadyampakeni, Ramdas Kanissery and Tara Wade Soil health is generally synonymous with soil quality and refers to the capacity of a soil to sustain biological productivity, maintain environmental quality and promote plant health. Soils are complicated ecosystems, and discussions of soil health must consider the links between soil functions and soil-based ecosystem services, such …
Irrigation Problem Prevention
By Ajia Paolillo To keep your irrigation system running efficiently, it is important to perform routine maintenance throughout the year. There are many types of issues that can affect your irrigation system, causing it to run poorly. Poly tubing and emitters can become clogged. Emitters can be blocked by weeds or broken through normal wear and tear. When these issues …
Sequencing Brings HLB Resistance Closer
University of Florida (UF) scientists achieved a major milestone in their quest to develop an HLB-resistant tree by sequencing the genome of a fruit plant that’s a close cousin to citrus trees. HLB is also known as greening disease. UF Institute of Food and Agricultural Sciences researchers sequenced the genome from trifoliate orange, in collaboration with scientists from the University …
Understanding the Fate and Persistence of Herbicides in Soils
By Ramdas Kanissery, Rachel Fenn, Biwek Gairhe and Davie Kadyampakeni Chemical weed control, using herbicides to manage weeds, is an important production practice in citrus groves. Herbicides applied in groves can end up in the soils from direct spray hits, indirect or non-target spray movement (also known as drifts) or release from the dead weeds and vegetation. In soil, the …
Indian River Variety Trial Attracts Visitors
Forty-nine growers and others participated in a self-guided, drive-through tour of the Millennium Block variety performance trial at the Indian River Research and Education Center (IRREC) on Oct. 9. “Several growers highlighted trees are off to a good start, and despite the fact they’re young, they could see clear differences,” said host and IRREC researcher Rhuanito “Johnny” Ferrarezi. Ferrarezi works …
Prospects for the 2020–21 Growing Season
Marisa Zansler, Florida Department of Citrus director of economic and market research, gave an update on fresh citrus prospects for the 2020–21 growing season during the recent virtual citrus Packinghouse Day meeting. Florida fresh citrus movement increased during the 2019–20 season, which was largely attributed to increased production, Zansler said. In addition to increased production, COVID-19 concerns served to move …
Maintaining Orange Juice Momentum
The Florida Department of Citrus (FDOC) normally launches minimal programs during the first quarter of the fiscal year and instead focuses on strategic planning. This year, though, in order to continue to build upon the momentum of 2019-20, the FDOC and its advertising agency, Edible, launched a robust campaign to drive sales of 100 percent orange juice (OJ) at retail. …
Is Parson Brown the Better Early Orange?
The old Parson Brown sweet orange variety is showing some characteristics that could make it more attractive than Hamlin, which has long been Florida’s leading early-season orange. “Observations made in commercial blocks in Polk and neighboring counties illustrate an improved canopy density, improved mature fruit retention and higher yields in the early-maturing Parson Brown sweet orange when compared to adjacent …
