BioAdvanced Season Long Weed Killer + Preventer Concentrate 32 oz is your all-in-one lawn solution designed to eradicate existing weeds while shutting the door on re-infestation. This concentrated treatment is crafted for homeowners who want a simpler, more effective approach to a lush, weed-free lawn all season long.
What makes this product unique is its three active ingredients—dicamba, penoxsulam, and dithiopyr—working together to deliver both post-emergent kill and pre-emergent protection. In other words, it doesn’t just remove the weeds you can see today (including stubborn crabgrass); it also reduces the chance they’ll come back in the future, giving your turf a stronger, healthier baseline to grow from.

How it helps you save time and effort: instead of juggling separate products for killing existing weeds and preventing new ones, you get a single, integrated solution that smooths out the lawn care routine. The result is a more uniform lawn with fewer bare spots, denser growth, and a visibly cleaner, weed-light look — especially in seasons when weeds are most aggressive.
