Crystal-Clear Victory Over Weeds
⭐️⭐️⭐️⭐️⭐️ Crystal-Clear Victory Over Weeds Spectracide 10.8 lb Weed & Grass Killer Review — Big Jug, Big Results The Spectracide 10.8 lb weed killer concentrate is a powerhouse for clearing unwanted plants fast — and the clear formula is a surprisingly nice bonus. No dye means no mystery blue footprints, no stained paws, and no evidence you waged war in the driveway. I used it on cracks, fence lines, stone edges, patio blocks, and random rebel weeds that popped up like they were paying rent. Results were quick — visible wilt within 24 hours and major clearing in just a few days. This handles grass and broadleaf weeds without negotiating terms. Mixing and application were easy following the standard concentrate dilution. It sprayed cleanly, absorbed fast, and didn’t clog my garden sprayer or declare independence halfway through the job. ✅ Most useful for: 🌿 Driveway and sidewalk cracks 🧱 Patio stones and block edges 🚫 Fence line weed rebellions 🏠 Concentrated, long-term yard maintenance 👍 Pros: ✔ Fast, effective weed kill ✔ No dye = no stains, no tracks ✔ Large 10.8 lb supply lasts a long time ✔ Mixes easily from concentrate ✔ Works on weeds + grass ✔ Rinses clean, sprayer friendly ⚠ Cons / Tips: • It’s non-selective, meaning it kills plants you want and plants you don’t — so aim carefully like a responsible plant assassin. • Don’t apply right before rain for best absorption. • Wear gloves if refilling or mixing — concentrate is concentrated, it didn’t name itself. Bottom line: If you want a fast-working, high-value, no-dye weed killer concentrate that clears areas without staining them, this one from Spectracide delivers. It’s effective, simple to use, and built for anyone who wants weeds gone without CSI-colored evidence. I’d absolutely buy again! 🌿💀👏🚀

Works great if you read the directions
I have a cool season lawn made up of primarily Kentucky Bluegrass and fescue. I have used this product several times with great results. It does not harm my lawn and definitely keeps the weeds in check. You must apply the product according to the directions. It is not effective on dry grass and must not be "watered in" like a fertilizer. You should only apply it to wet grass and avoid watering/rainfall in the following 24 hours.

Spectracide Weed Stop Crabgrass Preventer and Broadleaf Weed Killer...
4/18/2014 See long term results below. Zeroth- this is the only crabgrass product I've found that does not include fertilizer. First- this clearly states but I missed that this includes broadleaf weed killer, i.e., it includes multiple herbicides that work differently. I only cared that it included the Dimension herbicide. Second- I think some reviewers may be confused about application. This product contains both a pre-emergent herbicide and post emergent herbicides. The former will work if this is applied any time- it just has to be watered in. The latter has to be applied to damp leaves. Third: This includes a pre-emergent herbicide, dithiopyr/Dimension, meaning it is designed to keep some noxious seeds from sprouting, particularly crabgrass. Others it prevents include many noxious grasses and some broadleafs, including dandelions. Wiith the exception of very small crabgrass, dithiopyr won't control any of these that have sprouted, even if very small). This may be applied any time, wet or dry, but won't start working until it's watered in. Fourth- it includes broadleaf weed killers. For that to work best, the vegetation must be wet so the product sticks to the leaves, and needs to not be washed off for about 24 hours. Applied correctly it will kill a lot of weeds- if they are growing at that point. A limited selection of weeds that try to sprout later *may* be controlled. If applied early spring, the pre-emergent herbicide should help control noxious grasses and a limited set of broadleaf weeds. After things grow a bit, this can provide both pre-emergent control for seeds that sprout later in the season, and post emergent control for weeds that have sprouted. Personally, I think a purely pre-emergent makes sense for early in the season, and then a purely post emergent makes sense after a goodly crop of weeds have appeared. Application note: this is a very light and fluffy product and should only be applied in dead calm- no wind. 8/3/2014 Summary: it appeared to control the crabgrass (but read on) upgrading to four stars. I didn't keep track of which of three lawns I applied this to. I was testing three different products- Scott's crabgrass preventer, GreenView Crabgrass control, and this product. All appeared to help keep the crabgrass at bay, and given the three lawns have differing problems, it's hard to compare. Crabgrass preventer application note: one application a year may not be enough. These products work for 2-3 months, and crabgrass in my area often sprouts after that efficacy window. Unfortunately for buyers, but fortunately for online retailers, online is often the only place to purchase these products after early spring. Note on killing *existing* crabgrass: I've found two spray products that appear to effectively kill crabgrass: Fenoxaprop (Bayer hose end sprayer) and Quinclorac (GreenLight Wipe Out). I have tried the Fenoxaprop and it appears to be working, albeit slowly (as expected). I have tried the Quinclorac, a concentrate that you mix, but the reviews are positive.The GreenLight include broadleaf weed killer as well. I've also used Scott's Weed-B-Gone crabgrass killer with methearsonate. Some people say it works after many applications, but for me the effect was minimal. Scotts does have products with Quinclorac, which should work better.

Half powder/Half granulated
I’ve always been very happy with Spectracide products, but not this one. I am on a budget but I like taking care of my landscape. I used this today for the first time. It will rain for the next 3 days it’s a nice day today, very gentle breeze, perfect time to apply I thought. I loaded my hand held broadcast spreader and started to apply. The gentle breeze took away about 15 percent of the product into the air. Because it was so powdery and it’s brown I couldn’t see what landed and I overcompensated and used the entire bag on 800 square feet, being used to all granules. I stopped and put on a mask but it was a very dusty job and my eyes hair and clothing were full of dust when I finished. This being weed KILLER I cleaned up afterwards. I’m no tree hugging environmentalist. Bugs and weeds need to go, but I also don’t want to overcompensate and overuse product or put myself at risk. I also want it underground quickly so squirrels and things aren’t foraging into this stuff. Spreaders have settings based on the size of the granules and this half being fine powder and half granules you can’t distribute it properly. I usually use weed and feed granules and I will go back to just that. Having said all of that the end result of weed prevention has yet to be determined but the product will likely deliver on that aspect.

Great Weed Fighter
I have been using this for years. It works really well and is easy to spread around. It does work best right after rain or sprinkling or early morning dew. It’s very nice to the grass.

Easy to spread and effectively kills yard weeds for up to one month (not 5 months)
I spread this using a hand-held spreader. Unlike Scots, I found it to be light weight and well separated so it did not cause the spreader to clog or to spread unevenly. The fact that it was light weight made using the hand-held spreader a breeze. I now know to prep the yard by pulling any tall weeds and mowing first. And now the yards are growing in weed free. I will say, though, that this is my third application of a weed killer. The first time I used the spray bottle (a royal pain to use, very few and very small droplets which are difficult to spread). Several weeks later, I used a Scotts turfbuilder product with weed killer and fertilizer using one of their broadcast spreader (also annoying to spread due to the product clumping, and it being difficult to see what I was putting down). I can't use that again for a month, but the weeds are back yet again. So, this time, I used the Spectracide in granule form. The grass seems to be growing in weed free. I wish that it came in bigger bags. I had to use of bag for the back yard and buy a 2nd bag for the front. I also wish that it could take out tall weeds and that it's ability to control the weeds lasted longer. I am happy to see that it does help with weeds without destroying the grass. Hopefully, we will be out of the weed growing phase here soon.

DID NOT WORK!
Did absolutely nothing. Waste of money. Applied on day a good rain was coming, not a wash out. Waited a week, killed none of my weeds. Will never purchase again, should have listened to other reviewers.

This works. Rescue you Kanan from crabgrass.
I used this twice this summer once in the spring and once in autumn. Both times the results were noticeable within a week. We had massive strips of crab grass and many different kinds of dandelions, weeds, etc. all of them were gone by the end of the summer.. the large crab grass strips were hit again in the fall and they’re receding right now as a matter fact they’re all turning brown. I’m looking forward to using it again in the spring. The entire lawn has recover. This is a huge area, probably 50 yards x 30 yards so when it looks good, everyone really notices it. I like ordering it from Amazon because it tends to be out at the box stores and they pull it in late August so you can’t get any for your before winter application. I can recommend this.
