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

Worked twice then died within 3 months
Color: 7-in-1 Silver & Black/Beer Opener, Size: Rechargeable Set
The set is nice, looks good, well organized. The features are simple and the main opener looks and feels sturdy. However, roughly half the corks just get torn and don’t extract. Had 3 or less successes with as many failures. We only drink a few bottles a month at most. Now the unit just completely stops almost as quickly as it starts. You can reverse the screw to get it out when it stops and the motor seems fine when not pressed against a bottle/cork. The way it stops almost immediately when fully charged and cool means it isn’t an overheating issue or weak battery issue from what I can tell. Very disappointed and wished I’d returned it the minute I had the first issue. I thought it might just be me not holding it firmly enough or needing to learn some trick, but it was definitely the unit going bad. Buyer beware.

Easy to operate.
Color: Black/Battery
Very easy to operate. I was a little confused on how it operated but all I had to do is sit it on top of the can and it operates by itself. When it is done, the lid can be removed or set on top of the can. It doesn't leave any sharp edges. I was using a hand held one but because I have arthritis in my wrist, it is worth the price easy enough for seniors or disabled

Only worked for 1 month.
Color: Black/Battery
This product was delivered on April 20th and worked great. It made a nice clean cut in the metal with no sharp edges and the top of the can lifted up nicely. Yesterday, May 24th, it stopped cutting and unfortunately, the return window closed on May 20th.
