Glyphosate Weed Killer

Glyphosate is the world’s most used herbicide and is sprayed regularly to control unwanted vegetation in public spaces, gardens and in agriculture. It’s rarely used on its own but is an active ingredient in many herbicides. The most popular herbicide product is the world’s top-selling weed killer – Monsanto’s ‘Roundup’. Along with other ingredients, the chemical works by preventing weeds and plants from making the proteins that are necessary for growth. Glyphosate is a non-selective herbicide, meaning it will kill most plants. In agriculture, many seeds have been genetically modified so farmers can apply the herbicide to the whole field. These GM crops have been engineered to be unaffected by the glyphosate so they can continue to grow unharmed and only the surrounding weeds are damaged.

Concentrations of glyphosate found in herbicides varies from 40% for commercial applications, down to 1% for weed killers marketed for home use. Pure glyphosate is actually relatively low in toxicity, products usually contain other ingredients that help the glyphosate kill the plants. It’s the other ingredients which are mixed with glyphosate that make the product more toxic.


 In recent years, a large number of herbicides based on the active ingredient glyphosate have been introduced. All claim to be as good, or better, than the original – Roundup.  The ingredient statements on the label provides little help in differentiating the products since the contents are broken down simply as ‘active’ and ‘inert’ or ‘other’ ingredients.   This article will discuss how the contents of the glyphosate products may vary and factors that influence the performance of glyphosate.

Glyphosate is an herbicide. It is applied to the leaves of plants to kill both broadleaf plants and grasses. The sodium salt form of glyphosate is used to regulate plant growth and ripen specific crops. Glyphosate was first registered for use in the U.S. in 1974. Glyphosate is one of the most widely used herbicides in the United States. People apply it in agriculture and forestry, on lawns and gardens, and for weeds in industrial areas. Some products containing glyphosate control aquatic plants.

  • Glyphosate-resistant crops like canola, corn, cotton, soybeans, sugar beets, and wheat
  • Plantings, lawns, greenhouses, aquatic plants, and forest plantings

Features of Glyphosate Weed Killer

Glyphosate is rarely used on its own, but as part of a chemical cocktail, for instance with the trade name Roundup or Weedol.

These formulations are potentially far more dangerous. Dr Robin Mesnage of Kings College London, writes “We know Roundup, the commercial name of glyphosate-based herbicides, contains many other chemicals, which when mixed together are 1,000 times more toxic than glyphosate on its own.” Recent research has show these other chemicals include arsenic, chromium, cobalt, lead and nickel.

The European Food Safety Authority (EFSA) says that glyphosate is safe. However, most of their research is provided by the industry which created the herbicide. They haven’t tested the various individual commercial formulations. And regulation safety tests on mammals cover a short period, maximum 90 days. No-one knows the effect of longterm exposure to these toxic chemicals.
