The drop in Brazil’s 2024 citrus harvest is due, among other factors, to the long period of drought observed in the Citrus Belt, according to Fundecitrus. Mitigating problems related to periods of drought is the objective of several studies being conducted by Fundecitrus, Embrapa Cassava and Fruits, Coopercitrus Credicitrus Foundation and the Agronomic Institute (IAC). One of these studies takes …
A Brazilian study evaluated the effects of top pruning on orange trees located on the edges of an orchard as part of an HLB management strategy. The pruning was an attempt to attract the HLB-spreading psyllid from external areas to the orchard edges and control it, reducing its dispersion into the orchard. Fundecitrus and Embrapa Cassava and Fruits conducted the …
Fundecitrus researchers Marcelo Miranda and Wellington Ivo Eduardo participated in the recent XXIX Brazilian Congress of Entomology in Uberlândia in the state of Minas Gerais. In a round table discussion on fruit plant pests, Miranda addressed the challenges of implementing integrated pest management in citrus for insect vectors of pathogens. This includes the leafhopper that transmits citrus variegated chlorosis and …
Orange juice processing for the 2024–25 season was moving at a good pace in Brazil’s São Paulo state at the end of September, the Center for Advanced Studies on Applied Economics (CEPEA) at the University of São Paulo reported. The Pera orange has been the most processed variety so far, but the harvesting and processing pace of late fruit such …
Researchers Marcelo Miranda and Haroldo Volpe with Brazil’s Fundecitrus discussed control of the HLB-spreading psyllid during a recent visit to a South African research symposium and accompanying events. During the Citrus Research Symposium in Drakensberg, Miranda discussed studies developed at Fundecitrus on the management of the HLB-spreading psyllid (Diaphorina citri). In South Africa, HLB is caused by a bacteria different …
Fundecitrus’ annual survey of HLB in Brazil indicates that disease incidence rose from 38.06% in 2023 to 44.35% in 2024 throughout the Citrus Belt of São Paulo and Triângulo/Southwest Mineiro. This is the seventh consecutive year of growth for the disease. HLB was found in approximately 90.36 million trees. In total, there are 203.74 million orange trees throughout the Citrus …
Fundecitrus and its cooperators issued the first update to Brazil’s 2024–25 orange crop forecast on Sept. 10. The forecast of 215.78 million boxes for the São Paulo and West-Southwest Minas Gerais Citrus Belt is down 7.1% from the initial May forecast of 232.38 million boxes. With a total reduction of 16.6 million boxes, all varieties are expected to have lower …
Brazil’s citrus crop is suffering this season, according to Franklin Behlau, a senior researcher for Fundecitrus. That was the focus of a recent presentation he provided at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in Lake Alfred. “Things have changed in Brazil this season,” Behlau said. “We are a little behind …
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 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 …
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 …
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 …
Recent studies, including a partnership project between Fundecitrus and the University of California, revealed that the citrus greening bacterium Candidatus Liberibacter asiaticus causes physiological changes in psyllids, posing additional challenges to management strategies. An increase in the number of eggs, more frequent dispersal flights over longer distances and greater attractiveness to the host are some of the changes observed in …
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 …
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+ 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 …
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 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 …
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. WILD ANIMALS The research identified more than 300 species of wild animals in the Citrus Belt of São Paulo and Triângulo/Southwest Mineiro. Mainly, birds and mammals were found circulating or living in production environments …
The 2024–25 orange crop forecast for Brazil’s São Paulo and West-Southwest Minas Gerais citrus belt, published on May 10 by Fundecitrus and its cooperators, is 232.38 million 90-pound boxes. The projected volume represents a significant drop of 24.36% as compared to the previous crop of 307.22 million boxes. VARIETY BREAKDOWN Production by variety is divided as follows (figures in parentheses …
