Abstract: There is provided a method for inhibiting growth of a microbial pathogen of a plant. The method includes applying to the plant a combination including a nitrogen-bearing macrocyclic compound which is a singlet oxygen photosensitizer selected from the group consisting of a porphyrin, a reduced porphyrin and a mixture thereof; and a chelating agent to increase permeability of the microbial pathogen to the nitrogen-bearing macrocyclic compound; and exposing the plant to light to activate the nitrogen-bearing macrocyclic compound and generate reactive singlet oxygen species.
