What herbicide characteristic is desirable when you want to control creeping Charlie without damaging the surface turf?

• A. Flowable suspension.
• B. Photosynthesis inhibitor.
• C. Narrow spectrum.
• D. Broad-spectrum.

Answer: (C)

Targeted weed control in turf relies on using a herbicide with a narrow spectrum, meaning it affects only a limited group of plants. Creeping Charlie is a broadleaf weed you want to remove while preserving the surface turf. A narrow-spectrum product is designed to be effective against creeping Charlie while being safe for grasses, reducing the risk of turf injury. In contrast, a flowable suspension is just a liquid formulation, not guaranteeing selectivity; a photosynthesis inhibitor can damage non-target plants, and a broad-spectrum herbicide would kill many plants including the desirable turf. So, the best-desired characteristic is a narrow-spectrum herbicide.
