Rainproof in just 30 minutes, it delivers visible results within hours and covers up to 3,500 sq. ft. per bottle. Ideal for use around flower beds, walkways, and large lawn areas, it allows replanting within 1 to 30 days post-application, combining professional-grade performance with user-friendly application. ## Description Take control of your outdoor space with Roundup® Weed & Grass Killer₄ Concentrate. It kills tough weeds and grasses to the root, including dandelion, large crabgrass, poison ivy, clover (red & white), spotted spurge, and other broadleaf weeds. It is rainproof in as fast as 30 minutes, produces visible results in hours, and allows you to plant 1 to 30 days after application (see booklet for details). Use Roundup® Weed & Grass Killer₄ Concentrate in flower beds, around trees, along fences, driveways and walkways, freshly cut woody stumps, in large areas for lawn replacement, garden plot preparation and other areas of your yard. Mix the concentrate according to label directions and spot treat or spray evenly each gallon of spray solution over 300 sq. ft. with a tank or hose-end sprayer. Do not allow people or pets to enter the treated area or touch treated plants until spray has dried. One 35.2 fl. oz. bottle of Roundup® Weed & Grass Killer₄ Concentrate makes between 5.8 to 11.7 gallons (see booklet for mixing instructions) and covers up to 1,750 to 3,500 sq. ft. Review: Good Value - Great value for the money. Works almost immediately. Very easy to use with a sprayer for spot checks. Last a long time. Review: I Really Like this Item - I will try to be as honest as possible because I depend on other people's reviews and feel I want to help the best I can: Arrived as expected. I've been using ROUND-UP forever as the only brand of weedkiller I prefer. I've never been disappointed and this latest purchase did not disappoint either. This product makes some mighty claims, but it comes thru on each of them. I usually mix it according to the directions, with maybe a tiny extra drip more than the directions state. I also spray heavy, meaning a large harder to kill weed or plant has me holding the spray wand over it a little longer than a tiny weed might. I make sure they get a good soaking. But, just like the label claims, I can go back at the end of the day, and some weeds are already showing death is coming soon to them. Stubborn or hard to kill weeds might take longer to show their demise. But if you soaked them good, they will die. Speaking of which, always make sure you keep track of where you sprayed, because if you go back a short time later, the sprayed weeds will be dry and you can not tell you already sprayed them. I assume this is because number one, this product is mixed with water which dries quickly outside, and number two because its formulated to be safe and active even if it rains within an hour's time. Guess it has to dry fast so the rain will not dilute it. I've actually sprayed on a hot summer afternoon, and had a totally unexpected rain storm come in a soak everything. Sure enough, the weeds still die within a few days. I Recommend. Good Luck. ## Features - Roundup Weed & Grass Killer₄ Concentrate kills tough weeds and grasses to the root, including dandelion, large crabgrass, poison ivy, clover (red & white), spotted spurge, and other broadleaf weeds - Roundup Weed & Grass Killer4 Concentrate is rainproof in as fast as 30 minutes and produces visible results in hours - Allows for planting 1 to 30 days after application (see booklet for details) - Use in flower beds, around trees, along fences, driveways and walkways, freshly cut woody stumps, in large areas for lawn replacement, garden plot preparation and other areas of your yard - Mix Roundup Weed & Grass Killer₄ Concentrate according to label directions and spot treat or spray evenly each gallon of spray solution over 300 sq. ft. with a tank or hose-end sprayer ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C7Z2PG5Y | | Active Ingredients | Triclopyr,Triethylamine Salt 2.50%,Fluazifop-P-Butyl 2.00% Diquat Dibromide 1.50 | | Best Sellers Rank | #13,482 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #137 in Weed Killers | | Brand Name | Roundup | | Coverage | Covers between 1,750 to 3,500 square feet when mixed | | Customer Reviews | 4.7 4.7 out of 5 stars (2,004) | | Global Trade Identification Number | 00070183000166 | | Included Components | Roundup - 5376312 | | Item Form | Spray | | Item Type Name | Weed & Grass Killer | | Item Weight | 8 ounces | | Liquid Volume | 35.2 | | Manufacturer | Scotts Miracle-Gro | | Model Number | 5376312 | | Part Number | 5376312 | | UPC | 070183000166 | | Unit Count | 35.2 Fluid Ounces | | Warranty Description | Warranty | ## Product Details - **Active Ingredients:** Triclopyr,Triethylamine Salt 2.50%,Fluazifop-P-Butyl 2.00% Diquat Dibromide 1.50 - **Brand:** Roundup - **Item Form:** Spray - **Item Weight:** 8 ounces - **Liquid Volume:** 35.2 ## Images ![Roundup Weed & Grass Killer4 Concentrate - Image 1](https://m.media-amazon.com/images/I/71mZzF-y+BL.jpg) ![Roundup Weed & Grass Killer4 Concentrate - Image 2](https://m.media-amazon.com/images/I/71RL850sqWL.jpg) ![Roundup Weed & Grass Killer4 Concentrate - Image 3](https://m.media-amazon.com/images/I/61-ABVOk0+L.jpg) ![Roundup Weed & Grass Killer4 Concentrate - Image 4](https://m.media-amazon.com/images/I/71+pHoqe8KL.jpg) ![Roundup Weed & Grass Killer4 Concentrate - Image 5](https://m.media-amazon.com/images/I/71Q+OSwiHuL.jpg) ## Available Options This product comes in different **Size, Style** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Value *by S***D on March 12, 2026* Great value for the money. Works almost immediately.
