Spectracide Weed & Grass Killer Concentrate for Driveways & Walkways, 16 Oz

I have used Spectracide Weed And Grass Killer Concentrate since they first came out with the product, many years ago. What I like about Spectracide , over the other brands, is how quickly it works. Spray it in the morning on a hot Summer day, and the grass and weeds are dead by evening. With some similar products, new vegetation is already growing back in, before the weeds that were sprayed are completely dead. Here in Florida, we fight unwanted vegetation all year. I apply many gallons of it annually, with a hand pump backpack sprayer. I will offer a few tips from my years of experience with this product: First, I never purchase the small, pre-mixed, ready to use, spray bottles. The mix ratio on the concentrate is such that the small premixed containers are primarily water. It is to easy to mix the concentrate with water yourself, to pay extra for pre-mix. Also, by mixing it yourself, you can increase the strength for hard-to-kill vegetation. Be sure to follow the instructions for when and how to apply this product. Mixing Ratio: Non selective herbicides like this are expensive. One does not want to waste product by over-mixing more than is actually needed. For average weeds and grasses, increasing the mix ratio will not make it work any better. It will only waste product and increase the cost. The normal mix ratio for this type of Spectracide is 5, ounces of concentrate, per 1 gallon of water. For anything other than brush and hard-to-kill vegetation, I have found that 4 ounces per gallon, works just as well. Mixing 4 ounces of concentrate, per gallon instead of 5, will allow a 40 ounce bottle of concentrate, to make 2 extra gallons of spray material. To further reduce cost, I recently switched back from Spectracide Extended Control, to this regular Spectracide Weed And Grass Killer Concentrate. At least here in Florida, I could not see a performance difference in the 2 products. Storage: I try to mix in amounts where I will use all of the liquid in my pump sprayer at that time. Once mixed, this product does not store well for extended periods. When left unused for a few months or over the winter, it tends to develop a pulp-like consistency that clogs up the pump sprayer. It can then become difficult to clean from all of the sprayer parts. Over all, it is a fantastic product. It saves hours of work pulling weeds.

I sprayed this on grass growing in my sidewalk cracks, and the timeline speaks for itself: 2 Hours: The liquid was completely dry, and the grass was already wilting and losing its green color. 28 Hours: Heavy browning across the area, with nearly the entire strip dead by the next day. 99 Hours (~4 Days): Total die off. The grass was completely dried out, making it super easy to sweep right out of the crack. Super impressed with how fast and deep it works. Perfect for sidewalk joints, driveways, and patio pavers. I would definitely buy it again but I didn’t use much I have enough to last me awhile

This stuff is AMAZING! AND the price is great!!! It was getting to a point where we couldn't even tell where the walkway was located. I sprayed it once and things started to die. A second coat and it was clear->see the top of the picture- you can see where we stopped halfway up (we just put the second coat on where is brown).

The concentrate mixes easily, and one bottle goes a long way, which makes it a good value. I started noticing the weeds beginning to wilt after a few days, and within about a week they were noticeably dying off. It wasn't an instant overnight result, but with a little patience, it definitely worked. The key is to follow the instructions and apply it on a dry day when rain isn't expected right away. I also made sure to avoid spraying near plants I wanted to keep since this product doesn't discriminate between weeds and desirable plants. Overall, I'm happy with the results. It saved me a lot of time compared to pulling weeds by hand, and I would buy it again when I need to tackle stubborn weeds around the house.

Anyone having issues with this product is likely applying it when the weeds are wet, not spraying enough product on their weeds, or can’t do basic math to mix it well. It works incredibly well. How much product you have to apply to an area depends entirely on the ratio of your mixture. Go on the high end and take it slow. It works fine. Anyone who says otherwise is just failing to use it properly.

Best weed control product ever. Weve been using it for years. It's very fast acting.

This stuff works perfect when they say you can see results in three hours they’re right within three hours the weeds were dying thank you so much

Good stuff. Mix it, spray it, forget it.

Used it for what it was manufactured for thanx
