When performing selective treatment, which herbicide is appropriate for use on bermudagrass and broadleaf weeds?

The selected answer is appropriate because 2,4-D is a systemic herbicide that specifically targets broadleaf weeds while generally being safe for use on grass species like bermudagrass. This selectivity allows for the effective control of unwanted broadleaf plants without harming the desirable grass species, making it a reliable choice when managing mixed plant populations.

Glyphosate and Roundup, which are trade names for glyphosate, are non-selective herbicides that would kill both grasses and broadleaf weeds, making them unsuitable for selective treatment when wanting to preserve bermudagrass. MSMA is primarily designed for use on certain grass types and is less effective on broadleaf weeds. Thus, the unique characteristics of 2,4-D make it the best option when aiming for selective control in a mixed setting of bermudagrass and broadleaf weeds.
