Active Ingredients in Weed Control Products

We tested Scotts Turf Builder Weed & Feed3 and Weed Killer Plus side by side in 2024, seeking the best balance of dandelion and clover control for our 5,000-square-foot lawn. Both products delivered strong results, but Turf Builder’s dual-action formula-combining fertilizer with a broad-spectrum herbicide-stood out for its ability to nourish grass while targeting weeds. We noticed quicker results with Turf Builder, as it tackled dandelions with a faster-acting herbicide, though Weed Killer Plus offered a more aggressive approach for stubborn clover patches. Coverage was generous in both cases, with Turf Builder’s 14.29 lbs. providing a slight edge in longevity. While neither is flawless, Turf Builder’s holistic approach made it our preferred choice for maintaining a lush, weed-free lawn without compromising grass health. For those prioritizing ease of use and overall lawn care, it’s a solid contender-though we’d recommend experimenting with both to find your perfect match.
