Risk of Citrus Floral Rot in Brazil
Brazil’s Fundecitrus recently issued an alert about the risk of citrus floral rot during the current citrus flowering period. Citrus flowering periods must be on growers’ radar to avoid damage to orchards caused by citrus floral rot, also known as starlet. Attention must be doubled, especially if the flowering coincides with rainy periods, a determining factor in the occurrence of …
Fundecitrus Researchers Participate in Northeast Citrus Show
Fundecitrus researchers Silvio Lopes and Wellington Ivo Eduardo participated recently in the second edition of the Northeast Citrus Show in Aracaju, Brazil. Lopes gave a lecture on the two main Brazilian citrus diseases: citrus variegated chlorosis (CVC) and citrus greening. “In the orchards of Bahia and Sergipe, greening has not yet been detected, but there are psyllids,” Lopes reported. He …
Psyllid Nanopesticide Developed in Brazil
In Brazil, a more effective and sustainable insecticide for HLB-spreading psyllids was developed by Embrapa (Brazilian Agricultural Research Company) in partnership with the Institute of Chemistry of the State University of Campinas (Unicamp). The work resulted in a controlled-release system of the insecticide thiamethoxam molecule. Encapsulation was performed in polymeric nanoparticles, structures more than 80,000 times smaller than the thickness …
Fundecitrus Declares ‘Battle Time’ Against Psyllids
Brazil’s Fundecitrus recently declared battle in the fight against HLB-spreading psyllids. The citrus association’s recently launched “It’s battle time!” advertising campaign reinforces the need for rigor in psyllid control during the most critical period of the year. It is at this time, between the end of winter and spring, that high numbers of psyllids are captured in traps installed in …
What Will the Ideal Grove of the Future Look Like?
Since no cure exists for citrus greening-diseased plants, Brazilian researchers are developing ways to modify orange trees and the environment around groves to make it harder for greening-spreading psyllids to thrive. LOCATION AND LAYOUT The ideal grove envisioned by Fundecitrus researchers, in collaboration with the Spanish National Research Council/Polytechnic University of Valencia and Durham University (England), starts with a careful …
Task Force and Credit Line to Assist Brazil with Greening
Fundecitrus recently announced two efforts aimed at assisting Brazilian growers with citrus greening. A São Paulo task force will include a focus on the disease, and a credit line will be available for growers with greening in their orchards. In addition to greening, the public/private task force will address development of biofertilizer and biological research, studies to increase productivity in …
Researchers Discuss Rising HLB Incidence in Brazil
The incidence of citrus greening disease (HLB) in Brazil’s Citrus Belt of São Paulo and Triângulo/Southwest Mineiro rose from 24.42% in 2022 to 38.06% in 2023, according to Fundecitrus. The association’s annual survey indicates the disease increasingly demands more effective and collaborative measures. At a session of Brazil’s Expocitrus in June, Fundecitrus researcher Marcelo Miranda discussed the development of greening …
Brazil’s Harvest+ Reports Progress
Brazil’s Harvest+ project coordinator, Efraim Albrecht, recently traveled to Europe in search of mechanized and semi-mechanized solutions to improve citrus harvesting in Brazil. Harvest+ seeks to establish partnerships with companies that develop equipment and technologies that serve Brazilian orchards. It also seeks to contact universities and research centers that have innovative projects. In Seville, Spain, Move Agro’s coordinator and process …
HLB Control in Brazil and Florida Compared
A recent issue of the Annual Review of Phytopathology contains the article, “Management of huanglongbing of citrus: Lessons from São Paulo and Florida.” It discusses the lessons in HLB management, comparing what was done in orchards in Brazil’s state of São Paulo and in Florida. It also highlights the measures that worked and failed from the perspective of controlling the …
Pruning to Improve Citrus Greening Management
Pruning is an efficient strategy to improve citrus greening disease management in Brazil’s Citrus Belt, but requires appropriate procedures and attention from the grower, Embrapa and Fundecitrus researchers reported recently. Embrapa researcher Eduardo Girardi said an orange tree could produce normally without the need for pruning “if the orange tree has no restrictions on its growth.” Without growth restrictions, Girardi …
Brazilian Citrus Belt Rich in Wildlife and Carbon
Research carried out by Embrapa, with the support of Fundecitrus and financed by Innocent Drink, shows that Brazil’s Citrus Belt is abundant in wildlife and carbon.
