Which product is likely suited for controlling broadleaf weeds in turfgrass?

The most suitable product for controlling broadleaf weeds in turfgrass is a herbicide. Herbicides are specifically formulated to target and eliminate unwanted plants, including various types of weeds, without harming the grass. They function by disrupting the growth processes of the weeds, effectively preventing them from competing with the turfgrass for nutrients, water, and sunlight.

In contrast, insecticides are used for controlling insect pests and would not address the issue of weeds. Fungicides are designed to combat fungal infections and diseases in plants, which do not include broadleaf weeds. Fertilizers, while beneficial for promoting healthy turfgrass growth, do not have any weed control properties. Therefore, using a herbicide is the most effective approach when it comes to managing broadleaf weeds in a turfgrass environment.
