The high level of this resistance was confirmed by inoculating the plants with a bacterium strain, representative of the local population of the pathogen. In 1995 we have identified resistance in one Anthurium clone growing in a shade-house. dieffenbachiae) practically wiped out the whole crop.Īfter developing preventive measures to control the disease, we have initiated a breeding program for resistance to the pathogen. Resistance of anthurium cultivars to infection by Acidovorax anthurii, the causal agent of bacterial leaf spot disease was investigated using seven inoculation methods, four inoculum concentrations and two different plant ages towards developing a screening method for identification of disease resistance. This flower was leading the export market until 1983 when the accidental introduction of bacterial blight ( Xanthomonas campestris pv. In the French Antilles, the development of ornamental productions in the early seventies was based on anthuriums.
