Question

2,4-D is classified as a synthetic auxin herbicide that selectively kills broadleaf weeds in cereal crops such as wheat mainly because it causes uncontrolled, disorganised growth in susceptible plants by mimicking the action of which naturally occurring plant hormone?

2,4-D is a synthetic auxin herbicide that mimics the plant hormone auxin Indole Acetic Acid in susceptible broadleaf weeds, it triggers uncontrolled, disorganised cell division and growth, leading to twisted stems, leaf curling and eventual plant death, while narrow-leaved cereal crops are comparatively less sensitive owing to differences in growth habit and herbicide metabolism.
