What is the primary purpose of spot-treating broadleaf weeds with a selective herbicide in a lawn?

• A. To kill all plants in the area
• B. To control existing weeds and prevent further infestation
• C. To enhance the growth of desirable plants
• D. To prepare the soil for new grass planting

Answer: (B)

The primary purpose of spot-treating broadleaf weeds with a selective herbicide is to control existing weeds and prevent further infestation. Selective herbicides are designed to target specific types of plants, such as broadleaf weeds, while leaving desirable grasses unharmed. This method allows for a precise approach to managing weed populations without damaging the surrounding lawn. When spot-treating, the goal is not just to eliminate the current weed presence, but also to reduce the likelihood of those weeds regrowing or spreading. By effectively controlling these weeds, you create a healthier and more competitive environment for your desired turfgrass species, leading to a stronger lawn overall. This process is particularly useful in promoting the health and aesthetics of a lawn without the ramifications of broad-spectrum herbicides that would indiscriminately kill all plants in the treatment area, thus harming both weeds and desirable plants alike.
