I need to spray the area again?
“” Weed & Grass Killer

Experienced gardeners share their insights in answering this question :
When was the field mowed after spraying? If it was after three days, then the plants that were treated will die off. You probably should plan to retreat the areas that weren’t killed after those plants are growing again. (It will take a few days depending on moisture and other conditions.) In general, you can spray any missed plants 7 days after the first treatment. Then mow or seed the area 3 days after the second treatment. If the field was mowed prior to the three days after the first treatment, retreat the entire area after the new growth begins. For specific details, read the label for your Roundup product. Scotts has the label at the bottom of their product pages. All of the Scotts Roundup products are listed here: http://www.scotts.com/smg/catalog/productCategorySubSelf.jsp;jsessionid=64F09279DC15FE8877450FE65C85C38E?itemId=cat50096&navAction=jump .

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

If you unknowingly damaged your lawn with an herbicide like Roundup, you`ll have to do some physical renovation to the lawn. You`ll want to go ahead and remove the dead areas of lawn before more weeds move in to take its place. Then re-sod the patches or re-seed the areas, depending on the type of grass in your lawn.
The herbicide active ingredients in Roundup For Lawns are MCPA, quinclorac, dicamba and sulfentrazone. These herbicides are effective on a broad range of weeds that might infest the lawn such as dandelion, crabgrass and nutsedge. When used properly it will not kill the desirable turfgrasses in the lawn.
Though the plants absorb the herbicide rapidly, do not disturb for 7 days. It may take up to 7 days after the application for the grass to completely absorb the material and for symptoms to show. Depending on temperature, it can take up to 2 weeks for the entire lawn to die.
Make sure that children stay away from all pesticides and areas recently treated with pesticides. Do not let children or pets play on or touch lawns, gardens, golf courses, parks, or other grassy areas after weed killer is applied until 24 hours have passed since it was applied, or until after a rainfall or watering.
Pure glyphosate is low in toxicity, but products usually contain other ingredients that help the glyphosate get into the plants. The other ingredients in the product can make the product more toxic. Products containing glyphosate may cause eye or skin irritation.
No risks of concern to human health from current uses of glyphosate. Glyphosate products used according to label directions do not result in risks to children or adults.
It cannot stop seeds from germinating in the first place. Once it is absorbed into the plant structure, glyphosate spreads all around the plant—to its roots and leaves—and prevents it from making proteins that are necessary for its growth. This is what ends up killing the plants.
Glyphosate is a systemic herbicide that moves through the phloem and accumulates in the roots. That is why it “kills weeds, roots and all.” It breaks down quickly in the soil.
Most Roundup® Weed & Grass Killer products deliver visible results in a few hours, though some take a little bit longer. For Roundup® Max Control 365, it takes 12 hours to see visible results, but the trade-off is year-long hassle-free weed control.
Although spraying Roundup® For Lawns on your weeds is quite satisfying, resist the urge to do it too much. It works so well; one application is usually all you need to kill a weed. And some weeds can take as long as three weeks to die. If it`s still hanging in there in two weeks, give it another spray.
Controversial chemical was last reapproved for use in the EU in 2017. The European Commission Friday extended the EU authorization for the use of herbicide glyphosate until the end of 2023, according to Commission officials.
In fact, the National Center for Biotechnology Information states that glyphosate on skin can lead to severe irritation, photo-contact dermatitis, or even severe burns. As skin cells continue to deteriorate over time, they may increase the risk of the development of different types of cancer or medical conditions.
Luckily, you`re not alone. Weeds grow back after you`ve sprayed them because they still have roots or seedlings in the soil. Although spraying will kill the weeds, it won`t stop the roots from producing more weeds or the seeds from sprouting.
It degrades at a relatively rapid rate in most soils, with half-life estimated between 7 and 60 days [12]. Many studies have indicated that the presence of glyphosate in the soil can enhance microbial activity [32,33], while some studies have also shown the toxic effects of glyphosate on soil microorganisms [34].

Roundup superconceterte mixing – Roundup "" Weed & Grass Killer
ANSWER : I assume you are talking mixing ratios. In most cases a 1% roundup to water mixture will kill many plants. On very stubborn species you can go to a 2% concentrate but anything above that in my opinion you’re just wasting your money. More isn’t always better when it comes to weed killers.
