In fruit cultivation, Brazil occupies the third place among the world's major producers, especially with regard to fresh oranges, which accounted for the single largest growth in 2006 with more than 50,000 tons, an increase of 64% in volume and 85% in value compared to 2005 (AgroBrasil, 2006). The numbers reflect the dominance the country has maintained in the sector over the years, not only in the production of oranges and their byproducts, but also in the export of such products, especially fr

The project aims to develop/finalize, validate and disseminate technologies that strengthen the chain of production of family-based citrus, collaborating for its socio-economic-environmental sustainability, basically through prospecting in germplasm and the development of products rich in bioactive compounds. In order to conduct the project, a multidisciplinary and interinstitutional team was formed, composed of researchers, extension agents, representatives of the productive chain and consumers

Citrus HLB is the most important citrus disease worldwide. It is considered a quarantine pest present in Brazil and threatens to spread throughout the national territory. The project helps to stem the spread of the disease in the country. It is structured to generate three Solutions for Innovation derived from the HLB dissemination scenarios and three specific problems:Absence of validated contingency plans for the decision to contain HLB in citrus groves in the Northeast; Phytosanitary alert in

The sustainability of Brazilian citrus is compromised by risk factors identified by the Citrus Technical Team of Embrapa Cassava and Fruits, according to their strategic action plan, 2017-2021. Two problems were more relevant: 1. Advance of huanglongbing (HLB, ex-greening) in the country, the most severe phytosanitary challenge of the world's citrus industry (BOVÉ, 2014), and 2. Harmful effects of climate change, which have intensified extreme drought events (PACHAURI et al., 2014). In addition ...

Psyllids are small sap sucking insects with generally very narrow host plant ranges. Some of them are pests that cause major economic losses in agriculture, on ornamental plants and in forestry. They damage the plants by directly removing large quantities of sap or by the transmitting diseases. The chemical control of red gum lerp psyllids in eucalypt plantations in Brazil, for instance, costs millions of reais per year due to intensive use of insecticides. Another example is the transmission of

In the matter of control of HLB, the subject of study by several research groups has been the use of biological agents: predators, parasitoids or pathogenic microorganisms that are capable of decreasing the population densities of Diaphorina citri not only in areas where HLB is already established, but also in undersized areas where the high psyllid populations have not yet been subjected to such intensive spraying of pesticides. This project has contributed to the prospecting and characterizati

This project aims at the development of phytotechnical processes and citrus varieties to contribute to the management of HLB based on experiments installed at the FCC in an area where HLB occurs. Several scion/rootstock combinations and five citrus seedling planting systems and intercropping with other species will be selected for production, in addition to the occurrence of Diaphorina citri and the incidence of HLB.

Psyllids are small jumping insects in the superfamily Psylloidea (Hemiptera) which damage tovarious agricultural and forest crops. Some psyllids can transmit bacterial diseases to plants:the Asian citrus psyllid (Diaphorina Citra Kuwayama) transmits Huanglongbing disease (citrusgreening), currently considered the most serious citrus disease in Asia and America. There arean estimated 1000 psyllid species in Brazil, but approximately 90% have not yet beendescribed; as of 2012, only 73 species had

The objectives are to identify more efficient citrus genotypes in the use of irrigation water in three regions of Brazil, aiming at a management that optimizes the use of water and to associate the morphophysiological responses to the efficiency in the use of rootstock water evaluated at field level and under controlled conditions.
