Or is it safe?<\/p>    <p>You\u2019ve likely heard of Roundup either because it\u2019s a popular, inexpensive, effective herbicide or because recent safety concerns have developed, and its use is becoming a hotly debated topic. So which is it?

It was first developed in the 1970s by Monsanto and later acquired by Bayer AG in 2018.&nbsp;<\/p>    <p>There may be several active ingredients in Roundup, but the key active ingredient is glyphosate, a non-selective metabolic inhibitor. This means that glyphosate blocks key parts of the metabolic system in plants, causing them to die. It successfully kills all plants it comes in contact with, including weeds, grass, and flowers.<\/p>    <p>Monsanto developed a line of <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/18078304\/\" target=\"_blank\" rel=\"noreferrer noopener\">genetically engineered<\/a> Roundup Ready seeds designed to withstand glyphosate herbicide application. Many of our food products are grown from these seeds, including soybeans.<\/p>    <p><strong>Notable Exception:<\/strong> There are <a href=\"#faq\">some Roundup products<\/a> that do not contain glyphosate.<\/p>    <h2 class=\"wp-block-heading\" id=\"health-risk\">Does Roundup Exposure Cause Long-Term Health Risks?<\/h2>    <p>The long-term health risks of Roundup and glyphosate herbicide use is hotly debated. There are many studies that suggest there are long-term effects, while others have determined that there are <em>no<\/em> long-term effects. Let\u2019s take a closer look.<\/p>    <h3 class=\"wp-block-heading\">Evidence That Suggests Roundup <em>may<\/em> Have Long-Term Health Risks<\/h3>    <p>An article published by Interdisciplinary Toxicology, then by the NIH, <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24678255\/\" target=\"_blank\" rel=\"noreferrer noopener\">suggests<\/a> a link between glyphosate and Celiac disease and other gut problems. This study showed that \u201cFish exposed to glyphosate develop digestive problems that are reminiscent of celiac disease.\u201d<\/p>    <p>A study published by Surgical Neurology International, then the NIH, <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/25883837\/\" target=\"_blank\" rel=\"noreferrer noopener\">determined<\/a> that cows fed genetically modified Roundup Ready feed showed a severe depletion of manganese.

There have been many lawsuits filed against Bayer AG. U.S. News and World Report released an article in June 2022 that <a href=\"https:\/\/www.usnews.com\/news\/business\/articles\/2022-06-21\/supreme-court-rejects-bayer-bid-to-stop-roundup-lawsuits#:~:text=Last%20year%2C%20Bayer%20set%20aside,for%20earlier%20rounds%20of%20litigation.\" target=\"_blank\" rel=\"noreferrer noopener\">states<\/a> \u201cLast year, Bayer set aside 4.5 billion dollars to deal with the claims that glyphosate, the weed-killing ingredient in Roundup, causes non-Hodgkin lymphoma, a type of cancer. The company had previously taken a charge of nearly 10 billion dollars for earlier rounds of litigation.\u201d&nbsp;<\/p>    <p>Many plaintiffs claim they received a cancer diagnosis after using Roundup. Even though Bayer AG maintains that there is no cancer risk, they said they \u201cwould replace glyphosate in Roundup for residential use beginning in 2023.\u201d<\/p>    <h2 class=\"wp-block-heading\" id=\"apply\">How to Apply Roundup Safely<\/h2>    <p>When homeowners apply Roundup themselves, it\u2019s important to follow the directions carefully. Follow these tips:<\/p>    <ul class=\"wp-block-list\"> <li>Wait for a clear, dry, windless day. Moisture can dilute the product, making it less effective. Wind can spread the herbicide to areas not intended for application.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li>Wear proper safety clothing. Wear long sleeves, rubber gloves, and rain boots to prevent Roundup from coming in contact with your skin.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li>Carefully read product directions when preparing the solution. As a general rule, use 3-6 ounces of Roundup for every gallon of water.<\/li> <\/ul>    <p>Avoid inhaling the product or getting it on your skin or in your eyes. Wash your hands immediately after use, and don\u2019t touch the product when it\u2019s still wet.&nbsp;<\/p>    <p>A few <a href=\"https:\/\/www.webmd.com\/cancer\/herbicide-glyphosate-cancer\" target=\"_blank\" rel=\"noreferrer noopener\">potential health risks<\/a> from direct contact include:<\/p>    <ul class=\"wp-block-list\"> <li>Irritated skin, nose, eyes, and throat<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li>Increased saliva and mouth burns or pain, if swallowed<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li>Nausea, diarrhea, and vomiting<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li>If intentionally ingested, it can lead to death<\/li> <\/ul>    <h2 class=\"wp-block-heading\" id=\"alternatives\">What are some Roundup Alternatives?<\/h2>    <p>If you\u2019re looking for a Roundup alternative, <a href=\"https:\/\/www.consumernotice.org\/environmental\/pesticides\/roundup\/alternatives\/\" target=\"_blank\" rel=\"noreferrer noopener\">Consumer Notice<\/a> suggests these alternatives:<\/p>    <ul class=\"wp-block-list\"> <li><strong>Homemade solution:<\/strong> A half-gallon of vinegar, half cup of salt, and 2 tablespoons of dish soap. This solution is effective against annual weeds, but not as effective against perennial weeds (weeds that return year after year).<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li><strong>Mulch:<\/strong> With 2-3 inches of mulch, weeds do not receive the sunlight they need and are smothered under the weight. However, the most persistent weeds may still break through.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li><strong>Iron-based herbicides:<\/strong> Several iron-based weed killers have been approved by the EPA and are most effective against broadleaf weeds, which absorb iron easier than grass and die from oxidation within hours.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li><strong>Organic herbicides:<\/strong> These typically include natural oils and acids which are most effective against weeds that have already sprouted. They tend to be less effective against perennial weeds.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li><strong>Manual removal:<\/strong> The most effective way to remove weeds is to dig them up manually. Unfortunately, it\u2019s also the most time-consuming.<\/li> <\/ul>    <p>If you&#8217;d like more information on how to control weeds, check out our complete <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/guide-weed-control-yard\/\">Guide to Weed Control in Your Yard<\/a>.<\/p>    <h2 class=\"wp-block-heading\" id=\"faq\">FAQ About Roundup<\/h2>    <div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1656683276452\"><strong class=\"schema-faq-question\">Do all Roundup Products Contain Glyphosate?<\/strong> <p class=\"schema-faq-answer\">It\u2019s important to note that while glyphosate was invented by Monsanto and is contained in many Roundup products, there are <a href=\"https:\/\/gardeningsolutions.ifas.ufl.edu\/care\/weeds-and-invasive-plants\/not-all-roundup-is-glyphosate.html\" target=\"_blank\" rel=\"noreferrer noopener\">versions of Roundup<\/a> that contain a different active ingredient \u2014 penoxsulam, a relatively new herbicide.<br\/><br\/>Penoxsulam is becoming popular, especially among farmers, but it\u2019s still being researched.

For ethical reasons, researchers can\u2019t conduct experiments that would expose humans to differing levels of glyphosate and must rely on gathering circumstantial data. As mentioned earlier, some studies show a dangerous correlation between Roundup and humans, while others show no notable dangers at all.<br\/><br\/>However, Paul Mills, a public health professor at the University of California San Diego who has studied glyphosate exposure in humans <a href=\"https:\/\/www.healthline.com\/health-news\/can-weed-killer-give-you-cancer#How-much-exposure-is-harmful?\" target=\"_blank\" rel=\"noreferrer noopener\">said<\/a>, \u201cThere is consensus, among non-industry scientists, that there is no safe level of exposure to glyphosate.
