The Florida Citrus Growers’ Institute, presented by the University of Florida Institute of Food and Agricultural Sciences, was held in Avon Park on April 4. The annual educational event drew a good crowd of growers and allied industry.

Do not apply recovery techniques immediately after a freeze, cold-hardy citrus growers were advised after freezes hit their groves in December 2022 and January 2023. The best strategy is to wait to observe new growth until at least late spring, researcher Muhammad Shahid told the Georgia Citrus Association at its recent annual meeting. Shahid is a University of Florida Institute …
Marshal Sewell, representing the Mind Your Melon campaign, addressed mental health in agriculture and facing adversity during Peace River Valley Citrus Growers Association’s (PRVCGA) recent annual meeting. “Mental health was a perfect topic for this past year’s events,” said PRVCGA Executive Director Emma Keller. Florida citrus growers have seen production drop to its lowest level since before World War II …

The California Department of Food and Agriculture (CDFA) recently reported additional information about the state’s 2022–23 Valencia orange forecast of 16.2 million 40-pound cartons. This figure is equal to the 8.1 million 80-pound boxes forecast by the U.S. Department of Agriculture on March 8. The CDFA forecast, also issued on March 8, is below the prior season production of 17.2 …
In celebration of Earth Day on April 22, Uncle Matt’s Organic described how it uses numerous environmentally friendly practices. The company said use of cover crops in its groves helps control weeds and promotes healthy soil. The complex root systems from the cover crops nurture robust biodiversity in the soil.

By Nian Wang How the huanglongbing (HLB) pathogen Candidatus Liberibacter asiaticus (CLas) causes damage to infected citrus trees has been widely debated. A recent study demonstrates that HLB is an immune-mediated plant disease (Ma et al., 2022). It was discovered that CLas infection of citrus stimulates systemic and chronic immune response in phloem tissues, including reactive oxygen species (ROS) production, …
By Brenda Eubanks Burnette While passing through St. Augustine one weekend, I came across a sign in the Washington Oaks Historic District that made me stop and take a photo so I would look into it at a later time. In 2009, the National Register of Historic Places designated Washington Oaks as a national historic district. The Friends of Washington …
Plant pathologist Megan Dewdney put emphasis on new plantings during a mid-March discussion of phytophthora management for citrus trees infected with HLB. Dewdney is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor at the Citrus Research and Education Center, where she spoke. Dewdney’s presentation was part of an OJ break hosted by UF/IFAS Extension multi-county …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP Overnight success comes after years of hard work. In science, that means the “eureka” moment isn’t a moment at all. It comes after years of research that can cost millions of dollars. That’s a level of resources that the federal government helps deliver. We’re fortunate that the U.S. Department of Agriculture’s National Institute of …
In Brazil’s São Paulo citrus belt, infections of fruit by black spot usually occur from petal fall, in September/October, until the end of the rainy season, usually in April. Black spot can reduce production by up to 85%. Some studies have shown that the amount of fungicide applications to control black spot can be established according to the orange variety. …
Satsumas in the Sweet Valley Citrus region appear to have aced their first test of multiple days of subfreezing temperatures. It is still a wait-and-see approach with other varieties, however. One grower was extremely optimistic about satsumas, the cold-hardy mandarins that look to have survived December temperatures in the teens. “Satsumas are pretty darn good. We lost some leaves, got …
Brazil’s Fundecitrus on Feb. 15 participated in a meeting with state and local government representatives to discuss the country’s citrus greening (HLB) situation. Representatives of the Department of Agriculture and Supply (SAA) of the state of São Paulo and mayors of some municipalities in the citrus belt also attended.

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 …
Foliar sprays of insecticides timed to citrus flushing provided a significant reduction in Asian citrus psyllid (ACP) populations compared to standard grower practices, researcher Jawwad Qureshi reported. Timing sprays to flushing also led to a reduction in sprays, the University of Florida Institute of Food and Agricultural Sciences associate professor of entomology said in a virtual presentation on Feb. 22. …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a water and nutrient management workshop at the Citrus Research and Education Center in mid-February. In addition to seminars, a grove tour was provided to demonstrate a nutrient-rate trial currently underway at the center. Kelly Morgan, UF/IFAS professor of crop nutrition, spoke on recent activity to update citrus …
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 There is no crystal ball when it comes to anything in life, including agriculture. Growers are at the mercy of Mother Nature’s glory and fury. Over time, the citrus industry has developed production techniques and practices to help during the hard times. Microsprinkler irrigation is used both to provide targeted, much needed water during bloom, fruit set …
By Jude Grosser, Fred Gmitter and Maria Brenelli The new OLL (Orie and Louise Lee) series of sweet oranges (OLL-4, OLL-8 and OLL-20) are very high-quality processing sweet oranges that generally produce higher soluble solids and better juice color than Valencia. OLL trees are more vigorous than Valencia, and anecdotal evidence suggests they are slightly more HLB-tolerant than Valencia. Trees …
