Abstract: A method for controlling insect pests on a plant is provided. The method includes applying to the plant and/or to the insect pests a combination comprising: a nitrogen-bearing macrocyclic compound which is a photosensitizer that generates reactive oxygen species in the presence of light, the photosensitizer being selected from the group consisting of a porphyrin, a reduced porphyrin and a mixture thereof; and a chelating agent which is an aminopolycarboxylic acid compound or an agriculturally acceptable salt thereof; and exposing the plant to light in the presence of the insect pests to activate the nitrogen-bearing macrocyclic compound and generate reactive oxygen species.

Abstract: Provided herein are compounds of general Formula I: or agriculturally acceptable salts thereof. The compounds of Formula I can be used to improve the health of plants. For example, the compounds of Formula I can be used to inhibit a microbial pathogen of a plant, or to increase resistance of a plant to one or more abiotic stress. Methods of manufacturing the compounds of general Formula I, as well as synthetic intermediates are also provided.

Abstract: A method for increasing resistance of a plant to one or more abiotic stress is provided. The method includes applying to the plant a combination including: a macrocyclic tetrapyrrole compound selected from the group consisting of a porphyrin, a reduced porphyrin and a mixture thereof; and an oil selected from the group consisting of a mineral oil, a vegetable oil and a mixture thereof. Another method for increasing resistance of a plant to one or more abiotic stress is provided. The method includes applying a macrocyclic tetrapyrrole compound selected from the group consisting of a porphyrin, a reduced porphyrin and a mixture thereof, to at least one of a seed and a seedling of the plant. Corresponding compositions are also provided.
