You’ll get a 32 fl oz concentrate combining pre-emergent dithiopyr with post-emergent dicamba and penoxsulam to treat up to 4,000 sq ft. It targets broadleaves, crabgrass, poa annua and claims two-way nutsedge control while being labeled for common northern and southern turf when used as directed. Apply before germination for up to four months’ prevention or to young weeds for post-emergent control, follow label safety and timing, and see additional details below.
Some Key Takeaways
- Contains dithiopyr, dicamba, and penoxsulam for combined pre-emergent and post-emergent weed control.
- One 32 fl oz bottle treats up to 4,000 sq ft when mixed and applied per label.
- Labeled to control broadleaves, crabgrass, poa annua, and claims two-way nutsedge activity.
- Pre-emergent prevention lasts up to four months; post-emergent works best on young, actively growing weeds.
- Dicamba raises environmental and ornamental-plant risks; follow PPE, application timing, and resistance guidance.
What This Product Is and How It Works (Ingredients, Coverage, and EPA Registration)
While you’ll use it like a typical concentrate, BioAdvanced Season Long Lawn Weed Killer combines three active ingredients—dithiopyr (1.10%), dicamba (0.44%), and penoxsulam (0.10%)—to provide both pre-emergent and post-emergent control, treating up to 4,000 sq ft per 32 fl oz bottle. You’ll get a clear chemical breakdown on the label and an EPA registration number (92564-88) indicating EPA compliance. Mix and apply at the prescribed application rate for your lawn size, follow safety directions, and expect consistent performance. Consumer perceptions often note usefulness and coverage; using it as directed helps maintain shared trust among neighbors. The site also offers related tools and products for homeowners who enjoy their outdoor spaces, including guidance on lawn fungicide options.
Does It Kill and Prevent Weeds You Care About? (Target Weeds, Nutsedge Claim, and Turf Compatibility)
If you want a single product that both knocks down existing broadleaf weeds and helps stop new grassy weeds from sprouting, BioAdvanced Season Long combines post-emergent actives (dicamba, penoxsulam) with a pre-emergent (dithiopyr) to target listed species—dandelion, clover, chickweed*, carpetweed*, poa annua, crabgrass and others—and also claims two-way control of nutsedge (both pre- and post-emergent); it’s labeled safe for most common northern and southern turfgrasses when used as directed and covers up to 4,000 sq ft per 32 fl oz bottle. You’ll get broad listed-weed coverage and a nutsedge claim, but monitor for weed resistance and follow label application timing to protect turf and maintain community lawn standards. Homeowners who enjoy their outdoor spaces should keep a basic set of essential lawn tools on hand to apply and maintain treatments safely.
Real-World Performance: Application Timing, Results, and How Long Control Lasts
Now that you know what this product targets and its two-way nutsedge claim, timing and technique determine whether you’ll see those label results in your lawn. You’ll want precise application timing: apply pre-emergent before soil temps trigger germination for up to four months’ prevention, or use post-emergent when young weeds are actively growing. Results vary by species and lawn health; dense, well-watered turf shows faster decline. Post emergent efficacy is reliable on listed broadleaves and nutsedge when applied per label, but mature weeds may need repeat treatment. Expect prevention longevity near four months under proper conditions and care. For homeowners, selecting the right product and tools from a trusted lawn and landscape retailer helps ensure correct application and best results.
Safety, Mixing, and Step-by-Step Application for a 4,000 Sq Ft Lawn
Because you’re handling concentrated herbicide, take precautions for personal safety and for pets, children, and desirable plants before you mix or apply it. Wear personal protective equipment: gloves, long sleeves, eye protection, and a mask. Keep household members and pets away until treated areas dry. Measure concentrate per label to cover 4,000 sq ft, mix in a clean sprayer with the recommended water volume, and agitate gently. Apply uniformly, walking at a steady pace and overlapping swaths slightly. Avoid irrigation or rain for the interval specified on the label to prevent environmental runoff. Clean equipment and store product securely. Use products designed for post-emergent control when treating existing weeds to ensure season-long effectiveness.
Pros, Cons, and Alternatives to Consider Before You Buy
Having covered safe mixing and application for a 4,000 sq ft lawn, you should weigh the product’s strengths and drawbacks before buying. You’ll appreciate reliable pre- and post-emergent control, nutsedge action, and 4,000 sq ft coverage from a single 32 fl oz bottle. On the downside, active ingredients like dicamba raise environmental impact questions and may restrict use near ornamentals. Factor cost considerations: one bottle treats moderately sized lawns but repeated seasonal use adds expense. Alternatives include targeted spot treatments, organic pre-emergents, or selective herbicides with different chemistries—choose based on turf type, goals, and community norms. Many homeowners also combine herbicide use with cultural practices and tools to beat moss and boost lawn health.
Some Questions Answered
Can I Use This Product Near Vegetable Gardens or Edible Plants?
No, you shouldn’t use it right next to vegetable gardens or edible plants. It poses a drift risk during application and can move into garden beds by spray drift or runoff, and certain active ingredients may cause root uptake into nearby edibles. If you’ll treat turf near edibles, keep a wide buffer, avoid windy applications, and follow label directions precisely. When in doubt, choose products labeled safe for use around food crops.
How Long After Application Can Pets Re-Enter the Treated Lawn?
You can typically let pets re-enter after the treated lawn has fully dried, usually 24–48 hours. For pet safety, avoid letting animals lick wet areas or dig where residue may be concentrated; you’re reducing exposure risks by delaying access. Supervise outdoor behavior initially, keep pets off treated zones until you’ve watered or allowed sufficient drying, and consult the product label or your vet for specific re entry timing tailored to your situation.
Will It Stain Driveways, Sidewalks, or Clothing?
It’s unlikely you’ll see permanent stains if you clean spills promptly, but staining tests aren’t widely published, so you should assume some risk. Rinse concentrate from driveways, sidewalks, or clothing immediately with water and mild detergent to protect material compatibility. Wear old clothes and avoid splashes; test a small inconspicuous area on concrete or fabric first. Following label cleanup instructions helps keep surfaces and garments stain-free and everyone included safe.
Can I Overseed or Lay Sod After Treatment, and When?
You can overseed or lay sod, but wait: for seed timing, don’t plant seeds for at least 3 months after application; for sod, wait 2–4 weeks to make certain residuals lessen. Before planting, test and adjust pH, loosen compacted soil, remove debris, and add topsoil or compost—this soil prep helps establishment. Follow label directions and consider a small test patch first so you and neighbors feel confident about results.
Is This Concentrate Compatible With Common Hose-End Sprayers?
Yes — you can use this concentrate with common hose end sprayers if the sprayer accepts concentrates and you follow label directions. Check compatibility by confirming the sprayer’s calibration and approved materials, then mix the concentrate at the recommended ratios in the sprayer or tank. You’ll want to measure accurately, avoid cross-contamination, and test a small area. If unsure, reach out to the manufacturer or consult the product label for specific hose end compatibility.
