3 Best Eraser Weed Killer 2026 in the United States

The Control Solutions Inc. 82004319 Eraser Weed & Grass Killer Concentrate is a systemic liquid weed killer, which means it is absorbed by the plant and works from the inside out for thorough weed elimination. With its active ingredient being glyphosate, a well-known and effective herbicide, it targets a wide range of weeds and grasses.

The concentrate form allows for flexible applications, enabling users to mix it to the desired strength for various tasks, and it covers a substantial area up to 21 gallons, making it suitable for larger yards or gardens. Additionally, its rainfastness ensures that it remains effective even after rainfall, which is crucial for outdoor applications. However, as a systemic herbicide, it may take several days to see visible results, which might be a drawback for those seeking immediate action.

It's also important to handle the product carefully, as glyphosate requires proper safety precautions. The weight and size of the product are manageable, and its origin in the United States can be reassuring for users prioritizing domestic products. This weed killer is best suited for homeowners needing a reliable solution for persistent weeds and grasses across larger areas, but it may not be ideal for those looking for a quick fix or prefer organic methods.

The CONTROL SOLUTIONS 82004318 1 Quart Eraser & Grass Killer Concentrate is a natural weed killer with a potent active ingredient, 41% Glyphosate. This makes it highly effective against a wide variety of weeds, including annuals, perennials, trees, vines, and shrubs. As a systemic weed killer, it works by being absorbed into the plant, ensuring thorough elimination. The water-based formula is low-odor, which is a plus if you prefer less pungent products.

With no residual soil activity, it doesn’t affect the soil after application, allowing you to replant sooner if needed. It is rainproof within hours, ensuring effectiveness even if rain occurs shortly after application. The item is not discontinued, ranking decently in the Patio, Lawn & Garden category.

However, it comes in a relatively small quantity of 32 fluid ounces, which might not be enough for larger areas. Additionally, while Glyphosate is effective, some users might have concerns about its environmental impact despite being a natural material type. This product is likely best suited for homeowners who need to tackle various weeds and want a fast-acting, rainproof solution without worrying about lingering soil effects.

Martin's Eraser Max Super Concentrate, a 32oz liquid concentrate, is designed for post-emergent weed control. Its active ingredients include 43.68% Glyphosate and 0.78% Imazapyr. This combination makes it highly effective at killing existing weeds by being absorbed through foliage and transported to the roots. However, it does not work as a pre-emergent, meaning it won't prevent new weeds from germinating.

The product is systemic, meaning it will travel through the plant to ensure complete eradication, which is beneficial for tackling stubborn and deep-rooted weeds. Application involves mixing with water and using a sprayer, making it relatively easy to apply over large areas. The rainfastness, or the product's ability to withstand rain shortly after application, is good, ensuring that it remains effective even if it rains a few hours after treatment.

The product has a residual effect, meaning it continues to work for some time after application, reducing the need for frequent reapplication. However, being a potent chemical herbicide, it should be used with caution around desirable plants and in areas where pets and children play. Customer reviews are generally positive, with a 4.6 out of 5-star rating from 409 reviews, indicating a high level of satisfaction with its performance. It ranks #226 in Weed Killers, suggesting it is a popular choice among users. On the downside, the product's strong chemicals may not be suitable for organic gardening or for those looking for a more environmentally friendly option.
