    Product Description

    Indole-3-acetic acid is an auxin plant growth regulator that is found in all higher-order plants.1 It reduces plant height and shoot growth in tomato plants when used at concentrations of 10 and 50 µM.2 Root saturation with indole-3-acetic acid-loaded nanoparticles increases rooting efficiency in P. elaegrifolia.3

    WARNING This product is not for human or veterinary use.
