The BEST ONE SHOT label shows a 16-6-8 ratio, 12,500 sq. ft. coverage, and dual weed control for existing broadleaf weeds and crabgrass prevention.
You can read the full One Shot fertilizer label before buying, and the key specs deserve a close look. BEST ONE SHOT from JR Simplot Company delivers 16-6-8 fertilizer plus Trimec for broadleaf weeds and Dimension for pre-emergent crabgrass control — all in one 50-pound bag that covers up to 12,500 square feet of established turf. If you’re comparing weed-and-feed options, our one shot fertilizer product comparison covers the top-rated bags and their real coverage numbers.
What Does The One Shot Fertilizer Label Say?
The label identifies BEST ONE SHOT as a granular product for cool-season and warm-season turfgrasses — including Bermudagrass, Bluegrass, Fescue, Zoysia, Centipedegrass, and Bahia — and for non-turf areas like roadsides and rights-of-way. Its EPA registration (No. 2217-856-AA-7001) remains active as of June 2026. The active herbicide ingredients are 2,4-D, Dicamba, Mecoprop-p, and Dithiopyr. The product targets over 200 established broadleaf weeds while preventing crabgrass and other annual grasses before they germinate. The Greenbook label listing for BEST ONE SHOT confirms the full ingredient list and application specifications.

Application Timing: Pre-Emergent And Post-Emergent Windows
The label gives two timing rules that determine whether the product works as intended. Apply before crabgrass germinates for the pre-emergent effect to take hold — once crabgrass emerges, the Dimension herbicide cannot stop it. For post-emergent broadleaf control, apply when weeds are actively growing and the soil is moist. Do not irrigate for 24 hours after application; optimal weed kill happens 3 to 7 days after spreading. Split applications must be at least 30 days apart, and the label caps total use at 9 lb. per 1,000 sq. ft. per year.
States And Counties With Restricted One Shot Use
One Shot carries specific legal restrictions in New York that do not apply elsewhere. Dithiopyr is classified as a restricted-use pesticide in New York State, and the product is completely prohibited in Nassau and Suffolk Counties. In those two counties, only licensed commercial applicators may use it, and the annual maximum drops to 6 lb. per 1,000 sq. ft. Outside New York, homeowners can buy and apply BEST ONE SHOT without a license provided they follow the standard label rates.
Common Application Mistakes That Waste The Product
Five mistakes show up most often and each one can ruin the results. Watering within 24 hours washes off the post-emergent herbicide and cuts weed control significantly. Applying after crabgrass has sprouted eliminates the pre-emergent benefit entirely — the product can only prevent, not kill, emerged crabgrass. Exceeding 4.5 lb. per 1,000 sq. ft. in a single pass risks burning the turf and violates the label. Ignoring the New York restrictions can lead to fines or enforcement action. Using a spreader not designed for granular herbicides leaves uneven stripes and gaps that weeds will fill.
Safety, Storage, And PPE Rules From The Label
| Requirement | Label Rule |
|---|---|
| PPE | Chemical-resistant gloves, long sleeves, long pants, shoes plus socks |
| Irrigation hold | 24 hours minimum after application |
| Storage | Cool, dry place away from sunlight; do not store damp or warm |
| Aquatic toxicity | Toxic to fish and aquatic invertebrates; avoid water and runoff areas |
| Mixing warning | Do not combine if mixture foams, gels, separates, or thickens |
| Compatible liquids | Non-phosphorous liquid fertilizers only |
| Freeze tolerance | May be frozen — not damaged by freezing |
The label requires chemical-resistant gloves, a long-sleeved shirt, long pants, and shoes with socks during mixing and application. Store the bag in a cool, dry place out of direct sunlight — damp conditions can cause the granules to clump. The product is toxic to fish and aquatic invertebrates, so keep it away from ponds, streams, and any area where runoff could reach surface water.
Quick-Reference Checklist For One Shot Application
Spread at 4.5 lb. per 1,000 sq. ft. or less per pass using a drop or rotary spreader. Apply before crabgrass germinates in spring for pre-emergent control. Do not water for 24 hours after application. Wait 30 days minimum between split applications. Do not exceed 9 lb. per 1,000 sq. ft. total per year. In Nassau or Suffolk County, New York, a commercial applicator license is required and the annual limit is 6 lb. per 1,000 sq. ft.
FAQs
Can I use One Shot on a newly seeded lawn?
The label does not recommend application on newly seeded turf until the grass is well established — typically after the second or third mowing. The pre-emergent herbicide can prevent new grass seed from germinating.
Does One Shot kill clover and dandelions?
Yes. The Trimec herbicide combination (2,4-D, Dicamba, Mecoprop-p) is effective against clover, dandelion, thistle, and over 200 other broadleaf weeds listed on the label. Apply when weeds are actively growing for best results.
How long does One Shot stay active in the soil?
The Dimension pre-emergent provides roughly 3 to 4 months of crabgrass prevention after application, depending on soil temperature and rainfall. The post-emergent herbicides break down faster, which is why the label allows split applications spaced 30 days apart.
Can I apply One Shot with a handheld spreader?
The label requires drop or rotary-type spreaders designed for granular herbicides. Handheld broadcast spreaders can work for small lawns, but calibration is critical — uneven distribution is the top cause of poor results with handheld units.
Is One Shot safe for pets after it dries?
Keep pets and people off the lawn until the granules have been watered in or the treated area has dried completely — typically 24 hours after application. The label does not specify a re-entry interval beyond standard post-treatment drying.
