Specticle FLO Herbicide

Specticle FLO Herbicide is a professional-grade selective pre-emergent herbicide formulated with indaziflam for long-lasting control of troublesome grassy weeds, annual sedges, annual kyllinga, and broadleaf weeds in labeled warm-season turfgrass, landscape ornamentals, hedgerows, hardscapes, and natural areas.

As a Group 29 cellulose biosynthesis inhibitor, Specticle FLO controls weeds by reducing seedling emergence before they become established. It provides extended residual pre-emergence control of key weeds such as crabgrass, goosegrass, annual bluegrass, annual sedges, annual kyllinga, and many broadleaf weeds when activated by rainfall or irrigation.

Labeled Use Sites

It may also be used in landscape ornamentals, hedgerows, hardscapes, managed natural areas on golf courses, roadsides, non-bearing fruit and nut trees in residential plantings, and non-crop areas such as paths, parking lots, curbs, sidewalks, driveways, around buildings, gravel areas, loading ramps, educational facilities, storage yards, vacant lots, fence rows, parks, and hardscapes.

Application Notes

Apply Specticle FLO according to the product label and only to labeled sites. Specticle FLO must be activated by rainfall or light irrigation before weed germination for best pre-emergent performance. Uniform application is essential for satisfactory weed control. Apply in a minimum of 10 gallons of water per acre, or 1 quart of water per 1,000 square feet.

Do not apply to newly seeded turf, golf course greens, tees, collars, slopes immediately above greens, or weakened turf that requires significant recovery. Do not apply to cool-season turfgrasses or mixtures containing sensitive grasses unless thinning or removal is desired. Specticle FLO may inhibit root development, so observe all seeding, overseeding, sprigging, and sodding intervals on the label.

Looks great buy too short
Color: Red, Size: 4X-Large
Purchased for my son for a Christmas event at his job. He is 330pds and 6ft tall so I got the 4xl for him. It's fits perfectly in width BUT it's short. I know because he is tall I should have searched for a 4XLT but could not find one in the colors needed. But I purchased a white 4xlt tee for him to wear underneath and leave the shirt open it's looks great. So great shirt comfy and cozy well made and colors exactly as shown but if you are on the taller side maybe wear it as an over shirt with a tee underneath.

Well made, warm.
Color: Brown, Size: X-Large
A heavy yet soft flannel shirt. Nice on a foggy or light misty day. Flannel is a bit loosely woven but well sewn. Size reflects its lable. Its become a 'got to' shirt this fall.

Quality look
This is my second purchase of this shirt. Soft, thick, good quality. Usually worn open with a tee underneath. Sizing is normal and a good length. But it could also be tucked in. Looks great!

Great shirt
Color: Khaki, Size: XX-Large, Color: Khaki, Size: XX-Large
Wonderful shirt. Bought this for my husband to wear for family photos and it fit great, wasn't scratchy and he was so comfortable in it he actually wears it to work sometimes even to this day. I would buy this brand again. It washed it before he wore it, I didn't notice any shrinking.
