How Cornerstone Plus Works

Cornerstone Plus Herbicide contains glyphosate, a high-potency ingredient for the successful killing of broadleaf weeds and grasses. After spraying, the weed absorbs the herbicide and circulates it throughout the plant and down into the roots. It slowly kills competing weeds that strangle desirable plants and grasses in the same area. You can also use Cornerstone Plus with an adjuvant or a surfactant in the tank for optimal weed performance.

Where to Use Cornerstone Plus Herbicide

Use Cornerstone Plus Herbicide to kill unwanted weeds and grasses on Roundup Ready crops such as canola, cotton and soybean. It also targets weeds in pastures, range lands, greenhouses and shade houses. Apply Cornerstone Plus for habitat management or as an injection for woody brush and trees. It also keeps turfgrass, industrial sites, railroads and roadsides free of weeds.

Target Weeds

Cornerstone Plus Herbicide affects more than 100 broadleaf weeds and grasses. From barnyardgrass to carpetweed, this herbicide works after one spray and kills bothersome weeds where they grow. It also takes out many common weeds such as chickweed, crabgrass and dwarf dandelion. Other target weeds include:

Beautiful shelves upscaled my living room
Color: Brown, Size: 35.5in
Love these! They are pretty and look expensive on my walls. I like them so much I bought a second set for my bedroom. I used these in a corner to create a gallery wall effect and it’s beautiful. They were super easy to put up, they are very light weight and I’m not sure how much they can hold when properly installed but they seem to be able to be stable and carry a decent amount of weight as mine are used as a gallery wall and are holding tons of photo frames. These aren’t adjustable once they are up so be sure about where you want them placed, they definitely upscaled my living room and decluttered my walls. I get tons of compliments when I have guests!

Very nice shelves
Color: Black, Size: 15.7in
These shelves look so good. I used them to hold my pop figures and it put together my room very nicely. It was good for the price as well with how many it came with and the quality of the shelves. If you need more space then you can put the shelves together side by side to have more room.
