Systemic herbicides are particularly effective against which type of weeds?

Explanation:
Systemic herbicides move inside the plant after absorption, traveling through the vascular system to reach meristems and underground storage organs. This ability to reach roots, rhizomes, and tubers makes them especially effective at controlling persistent perennial weeds, which can regrow from these underground parts even after the foliage is damaged. Annual weeds, by contrast, complete their life cycle in one season and don’t rely on storage organs to the same extent, so the advantage of systemic movement is less critical for them.
