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.

Fast, Reliable Performance
I bought the UGREEN USB C to Ethernet Adapter 2.5G, and it’s been a solid addition to my setup. The connection is stable and the speeds are impressive, data transfers feel quick and consistent without the drops you sometimes get on WiFi. It’s plug and play, which I appreciate, no hassle getting it up and running. The build quality also feels durable, which is something I’ve come to expect from UGREEN. Overall, it delivers exactly what it’s supposed to, fast, reliable wired connectivity. UGREEN continues to put out quality products, and I look forward to trying more from them.

Solid, Well‑Built Adapter with Excellent Performance
I bought this adapter for my M1 MacBook Air so I could properly test the speeds on my new 2Gb internet service. During installation, my old cheap USB‑C Ethernet adapter kept capping out at 1Gb, and even the tech suggested the adapter was the bottleneck. After he left, I ordered this UGREEN model. I’ve had great luck with their products before and it did not disappoint. It has a solid, heavier feel with what seems like a metal casing, and it worked instantly. macOS recognized it right away with no drivers needed. I simply turned off Wi‑Fi, plugged it in, connected the Ethernet cable, and I was online immediately. My very first speed test hit right at 2Gb, and it’s been consistently fast and stable ever since. I also haven’t noticed any heat issues at all. Overall, a fantastic upgrade and absolutely worth it if you need true multi‑gig speeds on a Mac.

Reliable network speed tests and smb speeds
Got this on prime day for about $20 USD. For the price and quality it was definitely worth! Works perfectly and as you would expect. No driver installations or dropped connections so far, just plug and play. Sleek design, gets a little warm (which is expected) but not hot at all. Tested on compatible internal network speeds which showed to be reliable and fast Hardware tested on: - base m4 mac mini connected via usb c ugreen 2.5g adapter - over cat7 ethernet cable (overkill but cat6/cat5e under 100meters/328ft should be enough) - 2.5g ethernet switch - 2.5g port on nas iperf3 tests: - iperf3 tests from base m4 mac mini to another 2.5g device on a 2.5g switch - shows average bitrates of ~2.35 Gbits/sec smb tests from a usb3 connected to base m4 mac mini: - only took ~2mins to transfer 31.31 GB for 11 files in varying sizes - which on average came out to around a transfer rate of 2.087gbps - which is about 260.88 Megabytes per second - i'd imagine this would even be slightly faster for files directly on the mac but wanted to test with a real scenario - probably closer 290-300 Megabytes per second for files stored on the device rather than usb3 have not had a need to test this on mobile yet but iphones with the 10g usbc (and probably just usbc in general) should be fine i'm sure if you're looking into buying one of these you already know all this but some things to keep in mind. your mileage may vary based on your cable length and runs/environment surrounding your network/cables for any electromagnetic interference. but generally as long as you have 2.5gb compatible ports and cabling and you should be good to go!

Solid USB-C Upgrade for 2.5GbE - Good Value and Performance - Good for Mac Users
I’ve been using this Ugreen adapter for a 6 months now and it’s become one of my go-to accessories. If you have a device like the M1 MacBook Pro or Mac Mini that’s limited to 1Gb Ethernet, this adapter is a great way to unlock faster speeds, especially if you’re upgrading your home or office network to 2.5GbE. I have everything connected to a 10Gb switch after I upgraded my Synology NAS and needed a way to improve access to it for storage. Setup was truly plug and play, just connect the Ethernet cable to one end, plug the USB-C into your device, and you’re good to go. I noticed an immediate improvement in transfer speeds when moving large files to my NAS. This is perfect for anyone working with media or large data sets where Wi-Fi just doesn’t cut it. I was initially capped at 200MB/s. It more than doubled when I used the adapter to 200MB/s At around $20, it’s excellent value when compared to higher-end adapters that cost much more but often deliver the same result. It’s compact, feels well made, and I’ve had zero issues with performance or stability. It does get slightly warm during long transfers, but I haven’t seen any drop in connection quality or speed. If you’re trying to squeeze more speed out of your Mac Mini, laptop, or even a docked tablet, this is a solid upgrade. I keep mine on the desk and switch it between devices as needed. Highly recommended for anyone moving to a 2.5Gb network or needing faster wired performance.

MR. SULU… PREPARE FOR WARP SPEED. ENGAGE.
Rocket fast. Sleek, smooth design. Have another adapter from different company, which tends to fail when utilizing more than 1.5 GB. It just decides to downshift the first gear. This adapter does not. Speeds are scary. SpeedTest results are fun, watching the gauge being download teat and swing radically to the right. Pinned. Speeds coming in at 2,327 mb/s uploads at 2,150 mb/s (depending on time of day. Great for streaming content from laptop 4K, Dolby Vision Dolby Atmos, no problems… smooth no hiccups
