Herbicides that do not remain active in the environment for very long are:

Explanation:
Herbicides that don’t stay active in the environment for long are described as nonpersistent. This means they break down or are degraded quickly after application, so residues don’t linger in soil or water and there’s less carryover risk. Persistent would stay active for a long time, which is the opposite. Volatility is about a chemical’s tendency to evaporate and move to the air, not how long it remains active as a residue. Translocated refers to movement within a plant after uptake, not environmental persistence. So the best choice for short-lived activity is nonpersistent.
