Q: Can this be used around pigs? I have an inside pig that goes outside and grazes and my fence needs sprayed but wanna make sure it would be safe for my pig to go back in the yard after it dries.

- A: Hello! Thanks for your question. Roundup Weed & Grass Killer Concentrate Plus is not registered or labeled for use in areas where grazers are kept, even temporarily. Because the products are not labeled or registered for use in a pasture area or other area where grazers may be allowed, we must recommend keeping grazers out of the application area for 1 year.9 months agoHelpful?

Q: What's the recommended mix ratio for a 15 gallon sprayer
2 years ago2 Answers
- A: Hello! Thanks for your question. The dilution rate for Roundup Weed & Grass Killer Concentrate Plus is as follows: Annual Weeds: Use 3 oz per gal of water (3oz = 6 tablespoons or 18 teaspoons). Perennial, hard-to-control, or brushy weeds: Use 6 oz per gal of water (6oz = 12 tablespoons or 36 teaspoons). If you are uncertain whether you have an annual or perennial weed, use the highest dilution rate. Application at concentrations above label rate will not give better results, as plants can absorb a limited amount of glyphosate.9 months agoHelpful?

Hi, we're sorry to read about your disappointment with Roundup Weed & Grass Killer Plus and appreciate your feedback.
A complete kill will take 4 weeks. Apply when daytime temperatures are consistently between 60 - 85 degrees F. We recommend to water the area 24hrs prior to applying Roundup or apply a day or two after it has rained for best results. It's best to apply in morning after dew has evaporated. We recommend that weeds not be cut for two days both before and after the product application to maximize leaf surface and absorption.
We want you to be confident in our products. For this reason, we offer a product guarantee. If for any reason you, the consumer, are not satisfied with the results after using this product, you are entitled to get your money back. Limitations apply. At your earliest convenience, please reach out to us at 866-324-2647 if we can further assist.

Kills Weeds Dead
a year ago
I am so happy to have found a weed killer that works on all my pesky weeds. I have tried several brands over the years, and nothing works better for me than Roundup Weed & Grass Killer Concentrate Plus. I use it all around my yard, and in my landscaping, and more. Easy to use, and I love how quickly the weeds just go away. I would recommend.
Yes, I recommend this product.

Simply works

Kills everything it touches. Worked great on some invasion dewberry vines that had taken over a section of my yard and behind my shed. It did take a couple applications to cover/kill all of them. You can see the difference between the sprayed leaves verses the non sprayed leaves I'm about 24 hours.
Yes, I recommend this product.

Product works as advertised. Works well with pump sprayer and easy to use. Just 6 ounces per gallon of water and you’re good to go. I use on my sidewalks and walkways and in my boarder garden in my backyard.
Yes, I recommend this product.
