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 …
Brazil’s Fundecitrus has prepared and released the free Guide for Citrus Growers: Evaluation of Products to Reduce Damage Caused by Greening. The guide is aimed at growers, researchers and professionals working in citrus farming. The guide brings together suggestions for a thorough assessment in the orchard, allowing citrus growers and technicians to analyze the effectiveness of available chemical products and …
Fundecitrus researchers Renato Bassanezi and Silvio Lopes in April addressed the citrus greening situation in Brazil from an epidemiological point of view during the International Epidemiology Workshop held in Brazil. Lopes presented work on the potential of citrus plants in backyards being a source of Candidatus Liberibacter asiaticus (the bacterium associated with greening) inoculum for commercial orchards. Fundecitrus has been …
The impacts of kaolin and climate on HLB in Brazil were among topics addressed by researchers from Brazil’s Fundecitrus during the recent International Research Conference on HLB in Riverside, California. HLB is also known as citrus greening. Researcher Marcelo Miranda discussed results of a study on the use of processed kaolin in low doses to reduce the HLB-spreading psyllid population …
Fabrício Eustáquio Lanza, research coordinator at Brazil’s Cambuhy Agricola, recently told how his company has kept HLB at low and economically acceptable incidence levels. His presentation at the recent International Research Conference on HLB was based on a report he co-authored with Alexandre Tachibana, Ivan Brandimarte, Antonio Juliano Ayres and Renato Beozzo Bassanezi. The report follows: MANAGEMENT MEASURES Huanglongbing (HLB), …
Brazil’s Fundecitrus, in partnership with the companies Agricef and Move Agro, has created the Harvest+ project that seeks to improve the country’s orange harvest. In addition to enhancing the manual harvesting process, the project is searching for mechanized and semi-mechanized solutions for citrus farming. Harvest+ is in response to demand from producers and companies that want equipment capable of harvesting …
A study by researchers Gilberto Tozatti, Mauricio Mendez and Rodolfo Castro indicated the likely future significant reduction in Brazilian citrus acreage and production due to huanglongbing (HLB or greening). The calculations are based solely on the current Brazilian Citrus Belt and do not consider future citrus projects happening in areas outside of it. Tozatti presented the study at the recent …
Fundecitrus and its cooperators published the final orange production forecast on April 10 for the 2023–24 crop season in Brazil’s São Paulo and West-Southwest Minas Gerais citrus belt. The forecast calls for 307.22 million 90-pound boxes of oranges, unchanged from the February forecast. The final forecast by variety is: The season’s production was 2.2% lower than the prior year’s crop …
Several factors can influence the period of citrus leprosis control after acaricide applications, according to a study by Daniel Andrade, a professor and researcher from São Paulo State University in Brazil. The research aimed to better understand how these factors can affect and increase the leprosis control period. “We studied acaricides, the moment of application of the acaricide, the presence …
General Manager Juliano Ayres and researcher Franklin Behlau of Brazil’s Fundecitrus participated in the recent Australian Citrus Congress. Attendees discussed the impacts caused by citrus greening in affected countries like Brazil and worked to establish strategies for preventing and detecting the disease in Australia. During the event, Behlau gave a lecture at the Citrus Australia Biosafety Symposium and provided an …
A study carried out by Brazil’s Fundecitrus in partnership with the Agronomic Institute (IAC) showed that additional fertilization of orchards had no effect on increasing the production of trees with citrus greening. The research was conducted in well-nourished adult orchards with a low incidence of greening. Results were published in January in the journal PhytoFrontiers of the American Society of …
Fundecitrus has launched Evaluate Psyllid, a tool that will help citrus growers choose insecticides to manage the pest that spreads citrus greening disease. Evaluate Psyllid will make available the results of insecticide efficacy experiments on field psyllid populations in different regions of Brazil’s citrus belt. The insecticide efficacy data will be constantly updated as experiments are carried out. It will …
Studies with psyllid pheromones show that the insect’s behavior is altered when it is infected by the HLB-causing bacterium Candidatus Liberibacter (CLas). This makes it difficult to produce a commercial psyllid-control product based on the insect pheromone, Brazil’s Fundecitrus has concluded. “The sexual pheromone is an attractant produced by the female of the species, which promotes behavioral changes in male …
The Feb. 9 forecast for the 2023–24 orange crop in the São Paulo and West-Southwest of Minas Gerais citrus belt of Brazil is unchanged from December 2023 at 307.22 million boxes of 40.8 kilograms each. This represents a reduction of 0.7% when compared to the initial forecast for the season. Of the total estimated production, approximately 27.76 million boxes are …
A failed field test has led to a major discovery about Asian citrus psyllids (ACP). According to new research, the bacterium that causes HLB disease can interfere with ACP’s sense of smell, rendering some kinds of insect traps useless. The work is currently available as a preprint. HLB, also known as citrus greening, is caused by the Candidatus Liberibacter asiaticus (CLas) bacterium. …
Continuing Brazilian research into the application of neonicotinoids via drench for control of HLB-spreading psyllids shows higher efficacy than earlier results indicated. In September, Fundecitrus released preliminary results on the application of neonicotinoids via drench. At that time, tests carried out on a property in Casa Branca, São Paulo, showed that the efficiency of the molecules for this type of …
The updated forecast for the 2023–24 orange crop in Brazil’s citrus belt is 307.22 million boxes of 40.8 kilograms each. That’s a reduction of 2.12 million boxes, or 0.7%, from the September forecast of 309.34 million boxes. The update was issued Dec. 11 by Fundecitrus in cooperation with its partners. The forecast, by varieties, is: IMPACTS ON FRUIT SIZE In …
Brazil’s government, institutions and citrus growers need to join efforts to overcome greening “so that Brazil does not go through the same situation as Florida,” a São Paulo agriculture official declared Nov. 7. Orlando Melo de Castro, undersecretary of agriculture, made those remarks to about 500 people at an international citrus symposium in Araraquara, São Paulo. “To this end, we …
