Question: 1 / 400

For treatment to be effective against perennial weeds, you must?

Use a non-selective herbicide

Use a contact herbicide

Use a translocated herbicide to control vegetative reproductive structures

To effectively treat perennial weeds, the most important factor is to use a translocated herbicide that targets and controls the vegetative reproductive structures of the weed. This is because perennial weeds are able to regenerate from underground roots and rhizomes, making them more difficult to completely eradicate. Using a contact herbicide (option B) may only address the visible parts of the weed, leaving its underground parts to continue growing. Non-selective herbicides (option A) may also kill off beneficial plants and grasses in addition to the weeds. Applying herbicide during the dormant season (option D) may not be as effective as targeting the reproductive structures when they are actively growing.
