Inhibitory extracts of calamondin leaves associated with precipitous decline of Xanthomonas citri subsp. citri populations

The relative susceptibility of six Rutaceae family genotypes to bacterial citrus canker (CC) caused by Xanthomonas citri subsp. citri (Xcc) was assessed by measuring and comparing in planta bacterial populations over time following inoculation using a minimally destructive inoculation. These genotypes included lime (Citrus aurantifolia), grapefruit (C. paradisi), sweet orange (C. sinensis), calamondin (C. reticulata X C. japonica), kumquat (C....
