Oryzalin is a herbicide of the dinitroaniline class. It acts through the disruption (depolymerization) of microtubules, thus blocking anisotropic growth of plant cells.[1] It can also be used to induce polyploidy in plants as an alternative to colchicine.[2]
Oryzalin's mode of action is inhibition of microtubule assembly, so its HRAC classification is Group D (Australia), Group K1 (global) or Group 3 (numeric).[3]
