Methalpropalin is a dinitroaniline herbicide[2] used to control broad-leaf weeds.[3]

Research samples of methalpropalin have been formulated prior to 1977 by Lilly Research Laboratories.[4]

Methalpropalin's mode of action is to disrupt microtubule formation; this makes its HRAC classification Group D (Australia), Group K1 (global) and Group 3 (numeric).[5]

Little study has been done on methalpropalin.
