Specticle FLO Herbicide is a professional-grade pre-emergent herbicide for long-lasting prevention of annual grassy and broadleaf weeds in established warm-season turf. Containing 7.4% indaziflam, Specticle FLO controls or suppresses more than 75 weeds, including crabgrass, annual bluegrass (Poa annua), goosegrass, annual sedges, kyllinga, spurge, and oxalis. It can be used as part of spring and fall pre-emergent weed control programs in residential and commercial lawns and other labeled sites.
Specticle FLO is a Group 29 herbicide that inhibits cellulose biosynthesis in developing weed seedlings, preventing susceptible weeds from becoming established. While primarily a pre-emergent, it also provides limited early post-emergent activity against certain weeds, including annual bluegrass, crabgrass, and oxalis. It will not control plants emerging from established tubers, rhizomes, bulbs, corms, rootstocks, or woody vegetation.
The low-odor, non-staining liquid formulation is labeled for use in lawns, sod farms, sports fields, parks, cemeteries, golf course roughs and fairways, landscape ornamentals, hardscapes, Christmas trees, conifers, and other labeled areas. Avoid contact with the leaves or green stems of susceptible plants, as yellowing or tissue damage may occur.
For applications to sod farms, golf courses, and non-crop areas other than lawns, do not apply within 25 feet of ponds, lakes, rivers, streams, wetlands, or habitats containing aquatic or semi-aquatic plants.
Note: Bayer Environmental Science Professional is now Envu. Specticle FLO packaging may feature either Bayer or Envu branding.

Specticle FLO Herbicide offers long-lasting weed prevention for established warm-season lawns and other labeled areas. Proper application timing, rate, and activation are important for getting the best results from this pre-emergent treatment. Use the information below to learn when and how to apply Specticle FLO, where it can be used, and what to expect after application.
Specticle FLO provides pre-emergent control of more than 75 annual grassy and broadleaf weeds, including many difficult-to-control lawn weeds.
Common grassy weeds and sedges controlled include:
Common broadleaf weeds controlled include:
Refer to the Specticle FLO Herbicide label for the complete list of controlled and suppressed weeds.
Specticle FLO should primarily be used as a pre-emergent herbicide to prevent weeds before they emerge. It works in the soil to inhibit the development of susceptible weed seedlings as they germinate.
Specticle FLO is labeled for use on established warm-season turfgrasses, including:
Do not use Specticle FLO on cool-season turfgrasses such as fescue, Kentucky bluegrass, perennial ryegrass, or bentgrass.
Always follow the label for turf-specific application rates and restrictions.
Apply Specticle FLO before target weeds germinate. Application timing should be based on the weeds you want to prevent and local growing conditions.
Soil temperatures and local weed germination patterns are more useful for determining application timing than a specific calendar date.
Specticle FLO can provide residual weed control for up to 8 months, depending on factors such as:
Always use the labeled rate for your turfgrass and target weeds and do not exceed the maximum annual application rate.
The correct Specticle FLO rate depends on your turfgrass, target weeds, and desired length of control.
Refer to the Specticle FLO label for the appropriate application rate for your specific treatment.
Yes. Rainfall or irrigation is required to activate Specticle FLO in the soil for maximum pre-emergent control.
Once activated, Specticle FLO establishes residual control in the soil to help prevent susceptible weeds from becoming established.
Yes. Specticle FLO is labeled for use around many field-grown woody ornamentals and established landscape plants, but applications should be made carefully.
Yellowing or tissue damage may occur if the spray contacts susceptible herbaceous plant tissue.
Specticle FLO can interfere with desirable turfgrass establishment because its pre-emergent activity prevents susceptible seedlings from developing.
Yes, Specticle FLO may be tank mixed with certain labeled herbicides when additional weed control is needed and both product labels permit the combination.
This can be particularly useful when existing weeds are present, since Specticle FLO is primarily intended to prevent new weeds from emerging.
When tank mixing:
Mix only the amount of Specticle FLO needed for your application. If the mixture is allowed to sit, the product can settle in the tank.

I read the label on how much to use on an acre, but for those of us with tank sprayers I would prefer to know an amount of product per gallon of water.

I'm looking for a long lasting herbicide. If it is a pre and post emergent product will be great, no matter the price
Specticle G Herbicide, Specticle FLO, and Specticle 20 WSP are all different versions of the same active ingredient, Indaziflam, and would be comparable. G is for granules, FLO is a liquid and WSP is water soluble packets. The WSP form is no longer available. Either the G or FLO would be good options to use but will only prevent weeds from emerging and will not affect actively growing weeds.

If I apply in Fall, it tells to follow up with another treatment 45-90 days later. If you do that, will there be a need to re-apply a pre emergent in the spring?

You should use your Specticle Flo within 24 hours of mixing it in the tank. Per their label: Mix the amount of Specticle FLO needed for immediate application needs. Settling can occur if the spray mixture is allowed to sit over an extended period of time. Re-agitate the spray solution before application.
