2,4-D + MCPA

Description

Introduction and Mode of Action: 2,4-D + MCPA is a systemic and selective herbicide from the phenoxycarboxylic acid group. It is mainly absorbed through the leaves and acts similarly to plant auxins, effectively controlling broadleaf weeds in wheat and barley fields.
2,4-D works by deactivating indole acetic oxidase, leading to an increase in auxin concentration within plant tissues, which results in weed destruction.
