The first object of the present invention is to provide an endogenous auxin synthesis inhibitor. Furthermore, a second object of the present invention is to provide a plant growth inhibitor or herbicide using the auxin biosynthesis inhibitor. The present invention relates to a method for adding a candidate compound for an auxin inhibitor to a plant, screening a candidate for an auxin biosynthesis inhibitor that prevents expression of an auxin-inducible gene, and crushing the plant after adding the candidate compound By measuring the amount of endogenous auxin, thereby selecting a compound that actually inhibits auxin synthesis in the plant, and inhibiting the production of indolepyruvic acid in the presence of pre-adjusted tryptophan deaminase and tryptophan A method for selecting compounds is provided. More specifically, the present invention includes an auxin biosynthesis inhibitor comprising AVG, AOA, AOIBA, L-AOPP or an analog thereof, and a plant growth regulator and herbicide containing these compounds as active ingredients.
