BioAdvanced 3-in-1 Weed & Feed for Southern Lawns 10 lb — Weed Control, Insect Killer & Fertilizer

BioAdvanced 3-in-1 Weed & Feed for Southern Lawns Plus Insect Killer is a single-application granular formula that kills existing broadleaf weeds and listed insects, prevents new weeds for up to six months, and feeds Southern turf for healthier, greener grass.

This blue-bag granular treatment is designed specifically for Southern lawns — including Bermudagrass, Zoysia, Centipedegrass, and St. Augustine (including Floratam) — offering a combined weed control, preemergent prevention, fertilizer, and insect control in one product. It contains targeted active ingredients to address common lawn problems in warm-season grasses and is applied with a broadcast or drop spreader when weeds are actively growing and temperatures are between 50–90°F.

How quickly does it control weeds and prevent new ones?

The formula begins controlling listed existing broadleaf weeds after application and creates a residual barrier that helps prevent new weeds and crabgrass for up to six months when applied correctly. Timing matters: apply while weeds are actively growing and follow temperature guidance to maximize the prevention window.

• Starts controlling visible weeds soon after application
• Residual preemergent action helps prevent new weeds up to six months
• Apply between 50–90°F (avoid >85°F on Bermudagrass) for best results
• Use only on specified Southern turf species; not for Northern turf

Will it harm my Southern grass and when should I apply?

When used exactly as directed, the formula is labeled for common Southern turf types and is not intended to damage established lawns. Apply with an even spread using a broadcast or drop spreader and follow the label’s restrictions and temperature guidance to protect turf health.

• Safe for Bermudagrass, Zoysia, Centipedegrass, St. Augustine (including Floratam)
• Not labeled for Northern turf varieties — do not apply there
• Even coverage with a spreader ensures consistent feeding and control
• Read and follow label instructions and state restrictions before use

What insect problems does it address and how often must I treat?

This product contains an insecticide component that targets a range of turf pests, including fire ants (initial application only) and listed chewing and sucking insects. It is formulated as a one-bag, seasonal treatment; repeat applications should follow label intervals and local regulations rather than a preset schedule.

• Kills listed lawn insects such as fire ants (first application), armyworms, cutworms, mole crickets, and chinch bugs
• Fire ants are controlled upon the initial application only
• Check label for re-treatment instructions and EPA registration details
• One application supplies insect control along with weed prevention and feeding

How does the fertilizer component improve lawn appearance?

The slow-release fertilizer feeds established Southern turf, promoting greener, thicker growth for up to three months after application. Balanced nutrient release helps lawns recover from weed competition and builds vigor over the season when combined with the product’s weed- and insect-control functions.

• Slow-release nutrients feed turf for up to three months
• Encourages thicker, stronger Southern grass when used as directed
• Combines feeding and protection so you don’t need multiple products
• Apply evenly with a spreader for uniform greening

Who this is for: Homeowners and landscape professionals managing warm-season Southern lawns who want a single, science-based granular product to reduce broadleaf weeds, prevent new weeds for months, feed turf, and control listed insects. This product is best for lawns composed of Bermudagrass, Zoysia, Centipedegrass, and St. Augustine (including Floratam) in states where sale and use are permitted. Not for use on Northern turf types; always follow label directions and local restrictions before applying.
