Martin's Eraser 41% Glyphosate, manufactured by Control Solutions, is a systemic post-emergent herbicide that delivers broad-spectrum control of an extensive range of weeds.
This easy-to-use product is meant to be used as a spot treatment for invasive weeds in your home or property. It can also be used to prepare lawns for renovation and garden planting.
As a non-selective herbicide, Martin's Eraser 41% Glyphosate can be used to kill weeds and grasses in parking lot cracks, driveways, flower beds, and fence rows. This product works systematically through the foliage down to the root, killing the entire plant within days.
Tools Needed
This product can be applied using various spray equipment (backpack sprayer, hand pump, skid sprayer). A hand pump sprayer should do the job for the average home application.
How to Use
- Step 1: Determine how much Eraser Herbicide you will need for your application by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet, then multiply them together (length x width = square footage). To use this product as a spot treatment around your property, mix approximately 1.5 oz. of product per every 1 gallon of water to treat 300 sq. ft. For more challenging to kill weeds we recommend you use 2.5 ozs. of product per gallon of water. So for example, if you measured an area of 1,500 sq. ft. you would need to mix 7.5 ozs. of Eraser in 5 gallons of water.
- Step 2: Fill your sprayer halfway with the required amount of water. Add the adequately measured amount of Eraser and then fill it with the remaining half of water. Close the sprayer lid and then shake the sprayer until the solution is well mixed.
- Step 3: Apply the solution to the desired area via a fan spray setting for uniform coverage. Spray generously but not to the point of runoff. Plants should die within 2 to 4 days. If not, reapply after 7 to 10 days for particularly stubborn weeds.
Where to Use
Eraser 41% Glyphosate is labeled to be used along fences, in driveways, patios, sidewalks, brick and gravel walkways, curbs, around ornamental trees, shrubs, flower beds and plantings, grape vines, next to trees and nut trees, and around buildings to control weeds and unwanted vegetation, in preparation for the planting of ornamentals, trees, shrubs, desert landscapes, and rock gardens.
Apply the product where you see the pesky weeds growing: near trees, in your driveway, or in the cracks of your pathway. The product is best used close to the ground and near the weeds that are giving you trouble so as not to affect nearby grass or vegetation.
When to Use
The ideal circumstances for using this product would be during a warm day, as it is accelerated by warm, sunny weather. Also, make sure to apply it when there is no wind outside, and there is no possible translocation of the product to ornamental plants and flowers.
Safety Information
Eraser 41% Glyphosate is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product.
Keep children and pets away from treated areas until the spray has dried.
Special Considerations
On the label, you will find a mixing instructions table with exact measurements for almost every type of sprayer. Make sure to check it before mixing.

| Keith's Pro Tips | "Be careful when spraying around desired plants. A neat tip is to use a plastic container or cardboard as shields for the flowers, trees, and vegetation you want to protect when spraying." |
| Product Drawbacks | It’s also important to note that this is non-selective herbicide. Which means that it’s a herbicide that will kill almost all vegetation that comes in contact with it, so take care when spraying as to not affect beneficial plants in the process. |
