2,4-D is an example of:

Explanation:
2,4-D is a systemic, selective herbicide used to control broadleaf weeds, usually applied after weeds have emerged. It works by mimicking plant hormones (auxins), causing abnormal and unsustainable growth in susceptible broadleaf plants, which leads to their death. Grasses are generally tolerant, so it’s considered selective rather than non-selective. Because it moves within the plant and translocates to growing points, it is a systemic herbicide rather than a contact one, and it is not a fungicide.
