Customer Reviews for Spectracide 40 oz. Weed and Grass Extended Control Concentrate

This stuff worked right away. I sprayed it yesterday and today I already seeing the weeds starting to wilt. It even rained last night and it is still effective. Great stuff.

This product works quickly compared to other weed and grass killers I have used; however, it sometimes takes more than one application and I do have to apply it more often than I would like.

Worked good, as usual. Use it all the time. My go to choice herbicide.

It killed the weeds but they came back about a month later. The ground clear I had before was much more effective. It would last at least 9 months. I think it is outlawed now. :-(

The concentrate worked will. I added me re of the Christmas concentrate to make stronger and it did a wonderful job on killing the weeds

Good product. Works well.

Mix it a little stronger than what the instruction say and it works much better.

Only weed killer I use. Spray area where I don't want weeds to grow. Spray again in about two weeks. Weeds are gone for months before I reapply. Works very well to eliminate having to pick weeds by hand.

Nowhere near as good as the stuff in the white jug. After two days hardly anything was dead. Waste of money.

It worked well and quickly too

Works every time. Never disappoints.

This product works great! I have been buying it at Home Depot for some time now and will continue to do so.

Best weed & grass killer I have found. Would have given it 5 stars, however this store no longer carries the pre-mixed refill. I would rather purchase the prepared refill versus having to calculate the dilution and mix it myself.

When used at the highest mix level, this works as stated. Central Florida summer use.

Fast acting. Great results.

This Product” did a great Job..killing weeds an unwanted grass around the edge of my house…Love it …

Duradero y eficiente

It killed the weeds in my yard, they looked pretty healthy for a couple days after I sprayed and I admit I was worried for a hot minute, but the spray did the job. It has rained since I sprayed and, so far, I don’t see new weeds springing up!

This product is easy to mix and use. Seems to work for the most part. There are just some weeds that are so stubborn, even this weed killer struggles to get the job done. Not sure whey the local Home Depot doesn't carry it and I had to buy online. More than likely will buy again when this batch runs out.

I use the 8 oz per gallon option and get superior weed control. Safer than using glyphosate products, too.

Easy to use and did a great job killing weeds and overgrown grass!

Used it on gravel and stone landscaped areas to eliminate weeds. Does a geeat job of killing and keeping weeds at bay for a few months.

Sprayed weeds in the afternoon the next morning they had already turned brown. Much faster results than Roundup. I will use this product from now on.

I have a long gravel driveway, slightly sloping downward from street level. Rains wash weed and grass seeds into the driveway, so I am either pulling weeds or spraying to keep them in check. The weed killer I normally used, which is pretty good, was out of stock, so I purchased the Spectracide. I sprayed and within three hours, the grasses and weeds were shriveled and begin to brown up and die. Within two days, they were completely gone! And you do not need a lot of spray to kill them, just the fog of the spray appears to do the job. Highly recommended, but use carefully as it will kill any plant life it contacts.
