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.

Good steamer and brand name.
Style: Steam Starter
I gave 4 stars as Shark Steamer mop S1000 is a good product. My last one was the purple steam mop and lasted 15 years. It was used at least once a week on all floors and for mess. It has the power steam and wipe the dirt away. Fast and easy. I have sealed hard wood floors, lots of tile, have always had two large dogs and one messy spouse who seams to drop everything on the kitchen floor, and brings in mud. (The dogs are cleaner). Needless to say, it gets good use. Fill the tank, wait as instructions say 2-3 minutes, you will hear the steam and it ready. I like the washable pads and ordered six extra to have them on had. The last was you had to fill the tank, not removable. This new one has a removable tank which I like the idea. Easy to dump out any water remain to let dry. However, maybe because it’s new, I find the tank is a bit hard to remove, the instructions say to pull up and out. You have to just pull out. The button under the tank on the machine its self does push in to allow the tank to snap back into place, but to remove it takes a little figure power to pull out. It needs a tank release button to make easier for arthritis hands. But I am still sticking with this machine and brand, hope it does me just as well as the last one.

A good beginning Steam Mop for the price
Style: Steam Starter
I have been curious about Steam Mops for awhile now and thought for the price - why not? Pros: Price and general quality of product; simplicity of the "mechanics" of a steam mop, and watching the steam actually come out of the body of the mop into the pad; I've cleaned a few pretty dirty surfaces; but no tile grout areas like some of the impressive videos; generally I suppose I have a sense that I am REALLY cleaning something cause there's steam! Maybe it's just a mind thing you know the power of suggestion. Cons: cord could be longer; and the element that you fill with water is a little sticky to actually remove; it's almost as if you feel like your going to break something by having to 'force' the water bottle away from the mop; every time I do this - I still feel I may break it. Also; the pad to clean the floor with is large with most of the steam actually exiting right in the middle - so I have found myself using a basic "floor cleaner" from a squeeze bottle in order to actually feel like I am getting my floors extra clean. I don't put anything other than water in the water-bottle for the mop - without the use of anything else; the floors do appear cleaned - and evidenced by the dirt on the pad. I might suggest purchasing a few extra pads so you can keep them clean. I toss mine in the wash - seems to work. Conclusion: I would recommend this model mostly for those who just want to give the ole' steam mop craze a try; you can't beat the price for a basic-simple model. I may upgrade one day but for now - this works fine.

Simple and effective.
Style: Steam Starter
I'm glad I purchased this model. I previously had a more complex model with the detachable steamer. Eventually the steamer would no longer attach to the handle, the mechanism wore out. This one is super simple. Put water in. Push down to make steam. It gives off plenty of steam. I'm confident that my floors are getting clean and there are no frills to get in the way of productivity. I will be purchasing more pads, as others have recommended.

Buy it and you’ll be happy that you did!
Style: Steam Starter
I bought this for my fifth wheel trailer and it is wonderful! I love how easy it is to use on floors. It saves me time as it dries quickly. I actually mix some floor cleaner in with the water and it leaves a nice clean smell. I can plug it in to one outlet and do the bathroom as well as the living room floors because it has a nice length to the cord. It has no leaks and is the perfect size to fit in my front closet. Best steam mop by far!
