This project proposed analytical methods to use biophotonics applied to early diagnosis of Greening (HLB) - currently the worst citrus disease - with potential for large-scale application, when used in conjunction with precision agriculture techniques, to generate infestation maps for plant disease control. The percentage of error for each technique was evaluated through advanced statistical methods. The combination of techniques to increase the percentage of correct diagnoses was also evaluated

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

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.

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

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

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 ...

In the past years, Brazil has stood out for its leadership and high competitiveness in food production, a position reached especially due to the substantial efforts put into research, development and innovation, associated with free entrepreneurship, natural favorable conditions, abundant and efficient food production, and governmental efforts, notably those of the Ministry of Agriculture, Livestock and Food Supply (Mapa). However, if on one hand the quantitative issues regarding Brazil's food p

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
