## Questions & Answers

**Q: This product says it's 35.2 oz and to use 2.5 oz per gal. So that's about 14 gal total. Why does the purple label say ''makes up to 23 Gallons'' ?**
A: 2.5 oz per gallon of water is the standard, recommended mix. A couple of lines down on the mixing instructions, it says you can use 1.5 oz per gallon for "weed seedlings", hence their "marketing mathematics!

**Q: Does this kill humans as well as weeds?**
A: It is harmless to humans, animals, and insects.  It doesn't leech or accumulate and is broken down by bacteria in a few days.  It does have some surfactant soap in it, similar to dawn dish soap, which isn't good for fish.  
 Tort attorneys and the organic industry have been advertising false conspiracy theories that say otherwise.  Christopher Portier at the IARC in 2014 had it classified as a class 2a probable carcinogen the same as fried food and red meat, but he was employed by the tort attorneys in the Roundup cases and gladly accepted $160,000 for the favor.  The parent organization of the IARC, the WHO later stated in 2016 that it isn't a cancer risk, along with the USDA, FDA, EPA, Health Canada, European Food Safety Authority, and many other  regulatory agencies.  It is one of the few things that does not need a California cancer label.

**Q: What is the Expiration date?**
A: The bottle I received does not have an expiration date stamped on it.

**Q: does it kill poison ivy?**
A: You can add in a cup of bleach per gallon and it will cut through the wax on the poison ivy.  The same is true other plants with waxy coatings.

    Detailed Product Review: Roundup Weed & Grass Killer Refill
  

*by E***. on Reviewed in the United States on May 16, 2024*

I recently purchased the Roundup Weed & Grass Killer Refill, specifically the 1.25-gallon size, to address some persistent weed issues in my yard. After using it for several weeks in various areas around my property, here’s an in-depth review of its performance, application, and overall value.EffectivenessThe primary concern with any weed and grass killer is its effectiveness, and the Roundup Weed & Grass Killer does not disappoint. Within 24 hours of application, I noticed a significant wilting and browning of the targeted weeds and grass. By the end of the first week, most of the treated plants were completely dead. This product is particularly effective against a broad range of weeds and grasses, including tough perennial weeds. It works by penetrating the plant’s leaves and traveling down to the roots, ensuring a thorough kill that prevents regrowth.Ease of UseThe refill format of this product is convenient and user-friendly. I already had a Roundup spray applicator, and transferring the liquid from the refill container to the sprayer was straightforward. The refill container has a spout designed to minimize spills and waste, making the process clean and efficient. The 1.25-gallon size is manageable and provides ample coverage for multiple applications across different areas of the yard.Application VersatilityOne of the standout features of this product is its versatility. I used it in various locations, including flower beds, around trees, along driveways, and on walkways. It performed consistently well across all these areas. However, it’s essential to exercise caution when using it near desirable plants, as the non-selective formula can harm any green vegetation it contacts. Using a targeted spray technique or a shield can help avoid unintentional damage.Environmental and Safety ConsiderationsWhile Roundup Weed & Grass Killer is highly effective, it’s crucial to handle it with care. The product contains glyphosate, which has been a topic of controversy regarding its environmental and health impacts. It’s important to follow the safety instructions on the label meticulously. Wearing protective gear, such as gloves and long sleeves, and avoiding application on windy days can minimize exposure risks. Additionally, keeping pets and children away from treated areas until the product has dried is advisable.Longevity and Residual EffectsOne application of Roundup Weed & Grass Killer typically provides long-lasting results. In my experience, treated areas remained weed-free for several weeks. However, as with any herbicide, reapplication might be necessary for stubborn weeds or in areas with heavy weed pressure. The product does not leave a harmful residue in the soil, allowing for planting new flowers, trees, or shrubs in treated areas after a few days.Value for MoneyGiven its effectiveness and ease of use, the Roundup Weed & Grass Killer Refill offers good value for money. The 1.25-gallon size is reasonably priced, especially considering the coverage it provides. Compared to other weed killers on the market, it delivers reliable and consistent results, making it a worthwhile investment for maintaining a weed-free landscape.OverallOverall, the Roundup Weed & Grass Killer Refill is a powerful and reliable solution for managing unwanted weeds and grass around your property. Its effectiveness, ease of use, and versatility make it a valuable tool for gardeners and homeowners. While it’s essential to handle the product with care and be mindful of its environmental impact, its performance in eradicating weeds and preventing regrowth is impressive. For those looking for a dependable weed and grass killer, this product is a solid choice.

    The Best!
  

*by R***A on Reviewed in the United States on June 25, 2024*

Roundup always seems to work better than any brand we've ever used.  We live out in the country and have a 4' ditch across the front of our property.  My husband weed-eats it about once a month, and the county mows it about once every other month.  The rest of the time, we try to just spray it because it's kind of dangerous.  Roundup really helps keep the weeds down so the water can run through to the creek.  Obviously, we do it when there's dry weather.  Other sprays only seem to last a few days and the weeds seem to come right back as soon as it rains.  Not so with Roundup.  It kills the weeds and the weeds stay dead.  We got this half gallon on the limited time deal of 30% off and I grabbed it.  It was an excellent price for such a large amount!  It will last us all summer.  We've tried other brands and always regret wasting the money.  We go back to Roundup every single time.  It's just the best there is!

    Mixture
  

*by V***R on Reviewed in the United States on July 23, 2024*

Had to use the higher mixture to obtain the results I need. The lower mixer rate failed to kill the grass roots. Maybe the type of grass I have not sure. So I ended up using more then what was required to remove the grass. Won't happen the next time now that I know it requires the higher mixer rate.
