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:

  • Corn speedwell
  • Fleabane
  • Foxtail
  • Henbit
  • Johnsongrass
  • London rocket
  • Pigweed
  • Ragweed
  • Smartgrass
  • Stinkgrass
  • Wheat
  • Witchgrass

    Six Weeks

    12 hour or more is best.

    Yes at a higher rate of 2 to 3 oz per gallon mix

  • Will this kill trees? I have a fence line close to trees and I am wanting to use this on the fence line but i do not want to harm my trees.

    Be very mindful of Drift. I would use a surfactant as well. Don’t spray inside the drip line or on any suckers from your trees. Make sure you want to kill everything you spray.

    So far so good!

    I poured the liquid into a gallon container equipped with a battery powered sprayer. At first the liquid was too thick, so I had to dilute it with some soapy water, as advised by another user. This seemed to help, and I sprayed a large test area. I have given it a couple of days to sit, and I will check it tomorrow, Monday, August 19th. I really do expect good results, as the other user really did give the product a high rating.
