Pre-emergent herbicide, when applied at the right times of year, will control weed populations before you see them. They do this by inhibiting seeds from forming roots, thus killing them as they germinate.

Eradicating weeds when they germinate is the most efficient way to control weed populations is lawns, flower beds, and even gravel driveways and walkways. It’s time-efficient and cost-effective, saving you months of combating weeds by mowing, weed whacking, hand pulling, digging, and from using costlier products to spray out weeds.

  • 25 lb. bag covers up to 4,000 sq. ft.
  • 50 lb. bag covers up to 8,000 sq. ft.
  • Contains 16-4-8 + Iron plus Barricade pre-emergent herbicide
  • This pre-emergent contains a high amount of Nitrogen, so review the "when not to apply" exceptions below for your type of lawn.


Apply only at the recommended rate.

Use our yellow walk-behind spreader to distribute this granular product.

When to apply pre-emergent herbicide:

  • Apply 16-4-8 with Barricade to established Tall Fescue lawns in late winter and early spring to feed and prevent weeds. If you've already fertilized your Tall Fescue with nitrogen, then choose 0-0-7 with pre-emergent because it doesn't contain nitrogen.
  • Apply 16-4-8 with Barricade to established Bermuda and Zoysia lawns in spring during "green up" to feed and prevent weeds, usually from mid to late April.
  • Apply in the morning before temperatures rise above 80 degrees; do not apply during the heat of the day.
  • Apply it after one full growing season when your lawn in fully rooted in and you can no longer pull up areas of the sod, after you’ve mowed it at least three times, and after you can no longer see the seams.


When NOT to apply pre-emergent herbicide:

  • When seeding new lawns: Do not apply this product or any pre-emergent herbicide if you're planning on reseeding your lawn because it will inhibit germination of that seed too. If you have applied pre-emergent, wait 3-4 months before planting seeds, depending on climate conditions.
  • When laying new sod: Do not apply pre-emergent when laying sod because it will inhibit root formation if applied too soon. Likewise, do not apply pre-emergent before laying new sod - if you have applied pre-emergent, wait 3-4 months (depending on climate conditions) before laying new sod.
  • Don't apply 16-4-8 with Barricade to Tall Fescue in late spring or summer; apply it only during cool months; due to high Nitrogen, don't apply to Tall Fescue during warm months.
  • Do not apply to Centipede due to the high nitrogen; choose 0-0-7 with pre-emergent instead
  • Don't apply 16-4-8 with Barricade to warm-season lawns like Bermuda, Zoysia, and St. Augustine in fall when going dormant or in winter or spring before green up; due to high Nitrogen apply it only when these lawns are actively growing in late spring. Instead, apply 0-0-7 with pre-emergent in fall and winter.
  • Don't apply too soon: If you laid warm season sod in autumn, chances are it will need one full growing season (summer) to root in and fill in the seams, thus skipping the winter and spring applications. If you laid sod in the autumn, here is a general application timetable:
    • Zoysia - Safe to apply after Zoysia sod is 12 months old
    • St. Augustine - Safe to apply after St. Augustine sod is 12 months old
    • Centipede - Due to high nitrogen, not safe for Centipede at all
    • Bermuda - Safe to apply after *Bermuda sod is 6 months old
    • Tall Fescue - Safe to apply after Tall Fescue is 4 months old


*TifTuf Bermudagrass is the quickest sod to establish and beats expectations for filling in the seams. If you lay the TifTuf Bermudagrass variety late summer and it’s fully rooted in and no seams are visible, it’s safe to apply the winter application of pre-emergent herbicide.

Time will tell
I’m always weary about how little or how much I spend on wiper blades. Typically wiper blades are a great example of you get what you pay for. When I’m looking to replace blades, though, I’ll often try and see what’s out there before I go spend $25 a piece on wipers. I came across these and they’re highly praised and so I figured why not. I cannot speak on their durability and longevity, but I can comment on my experience with them so far. These are plastic blades. Keep that in mind. They are not heavy or rigid like a metal blade, but also don’t feel super cheap either. The quality of plastic seems adequate for what these things cost. Install is easy, and shouldn’t take more than a few minutes. What I’m very impressed with is how clean of a wipe it makes. They don’t leave anything behind and I haven’t experienced any chatter. I don’t expect these to last as long as premium blades, but I also don’t make gamble purchases like this expecting unrealistic results. If they do happen to have a decent lifespan, then it’s a pleasant surprise and a great value.

Seriously good wipers

These things are awesome. I'd say they are on par with what comes on the car from factory.
