Selective weed control programs usually include which of the following?

• A. Release of grasses and Control of grasses
• B. Release of grasses and Control of broadleaf weeds
• C. Release of broadleaf weeds and Control of grasses
• D. Control of grasses and Broadleaf weeds only

Answer: (B)

The main idea is to promote the plants you want and suppress the ones you don’t. In many weed-control programs, the goal is to establish or maintain a dense stand of grasses, which are the desirable component in turf, pasture, or right-of-way vegetation. Broadleaf weeds are often the troublesome competitors, but they’re typically more easily targeted with selective herbicides that spare grasses. So the effective approach is to release or promote the grasses and at the same time control broadleaf weeds to reduce competition and improve stand quality.

That’s why this option is best: it aligns with keeping grasses dominant while removing the broadleaf weeds that would otherwise crowd them. The other approaches would either harm the desired grasses or attempt to remove the wrong group (for example, trying to control grasses or releasing broadleaf weeds), which doesn’t support a grass-dominant, weed-controlled outcome.
