Method for sensing plant hormone using rare earth compound, sensor using the same, and method for early detection of disease infection in plant

Abstract

Provided is a method for sensing methyl salicylate, which is a plant hormone released when a plant is infected with a disease in cultivation of plants including agricultural crops, and thereby provided a method for early in-situ detection of disease infection in a plant. With the present embodiment, disease infection in a plant can be detected at an early stage by utilizing a rare earth compound that selectively recognizes and forms a complex with methyl salicylate, which is a plant hormone released when a plant is infected by a pathogen, as a receptor for sensing, and by utilizing a fluorescence emission phenomenon and a change in electrochemical behavior after the reaction with methyl salicylate.
