Choosing Between Them
My top recommendation is the BioAdvanced Brush Killer Plus One-Gallon Ready-to-Use bottle, which I rank first because it delivers the best balance of volume and practical application for most residential yards. If you manage an expansive rural expanse, the Gordon's formula suits your needs, whereas the smaller Southern Ag quart works best for precise spot treatments.
You must remember that all these systemic herbicides require careful application to protect nearby desirable plants from accidental drift. Taking your time on a calm, windless day will ensure your landscape stays healthy where you want it green.
