| Abstract | |
The citrus canker disease is considered one of the most important citrus diseases due to its ability to spread on farms, and to damage plants and fruits. The damage, caused by the citrus canker, can be devastating, because the main control actions involve the eradication of infected plants and other plants nearby, causing large economic losses. Brazilian law requires an extensive testing protocol to confirm the diagnosis. Delays in diagnosis tests allows the spread of the disease. Therefore, any effort to accelerate this procedure will have a major impact in this area. This is the motivation of our work, where we apply the fluorescence imaging spectroscopy technique on citrus leaves with the goal to evaluate the diagnostic capability of this technique in asymptomatic plants infected with citrus canker in the laboratory. The goal is to determine the minimum time delay between infection and accurate diagnosis of the disease. This study was applied to experiments involving non-destructive and destructive samples. The results show the possibility of applying this technique in the detection of citrus canker. (AU) | |
