This invention relates to the application of a stabilizer for preventing or inhibiting discoloration in amide herbicide formulations and the herbicide itself, belonging to the field of pesticide formulation technology. The stabilizer is epichlorohydrin and / or BHT; the application involves using the stabilizer in amide herbicide formulations to prevent or inhibit discoloration. The amide technical grade is one or more of acetochlor, metolachlor, butachlor, and propachlor. The amide herbicide comprises, by mass fraction: 20%–90% amide technical grade, 3%–30% emulsifier, 0.1%–2% stabilizer, and 1%–75% solvent.
