Glyphosate is the world’s most popular weedkiller. It has been used in agriculture and gardens for decades, yet its safety remains a controversial topic.
Glyphosate has been linked to cancer, although some studies have shown it to be safe when used as directed. However, it remains controversial and with the climate shifting towards sustainability and ethical farming, is there a safer alternative?
This article will explore the science behind glyphosate and provide an overview of the controversy surrounding this commonly-used herbicide.
We’ll look at what makes glyphosate so effective, how it works in plants, and why it might pose health risks to humans who are exposed to large amounts of this chemical compound.
Finally, we’ll examine some potential strategies for reducing your risk if you choose to use glyphosate on your property or garden.

The science behind the product
Glyphosate is a potent herbicide that has been widely used to control weeds in agricultural and residential areas for over four decades. It is a broad-spectrum systemic weedkiller, meaning it is able to target a wide range of grasses, broadleaf weeds and other plants. The active ingredient in glyphosate binds tightly to many organic materials and is highly soluble in water.
It works by inhibiting the growth of weeds, particularly those in the grass family. The active ingredient in glyphosate works by blocking the enzyme EPSP synthase, which is necessary for plant growth and development. This blocking effect prevents plants from producing the essential amino acids they need to survive, resulting in death within a few days.
Glyphosate is effective because it is highly soluble and can easily spread through soil and water. It also binds tightly to many organic materials, meaning that once it enters an environment, it can stay there for a long time. Of course, this means that glyphosate can be carried away by runoff and eventually enter into nearby water sources, which is one of the main environmental concerns associated with its use.

How does Glyphosate work
Glyphosate is a herbicide used in agriculture and home gardens to control weeds. It works by targeting a plant enzyme called 5-enolpyruvylshikimate-3-phosphate synthase (EPSP), which is essential for the synthesis of certain amino acids that are necessary for plant growth.
When this enzyme is blocked, the plants can no longer produce these amino acids and will eventually die. Glyphosate also binds tightly to soil particles, so it can stay active in the environment even after it has been applied. This means that glyphosate can continue to kill weeds long after its application, making it an effective tool for weed control.
Glyphosate is a broad-spectrum herbicide, meaning that it affects many different types of plants. It also breaks down quickly in soil and water, so it does not linger in the environment for long periods.
However, glyphosate has been associated with some negative environmental impacts, including the death of beneficial organisms like bees and other pollinators.

Health effect on plant growth
There are reports of both positive and negative impacts on plants when exposed to glyphosate, depending on the type of plant, concentration level, and environmental conditions.
In general, studies suggest that glyphosate can reduce overall plant biomass production by reducing photosynthesis rates as well as affecting nutrient uptake from soils.
Additionally, there is evidence that suggests glyphosate may induce oxidative stress in some plants leading to reduced root development and stunted growth.
Furthermore, research indicates that long-term exposure to high levels of glyphosate may lead to increased susceptibility to diseases or pests which can further affect overall plant health and productivity.
Health concerns associated with glyphosate
Glyphosate has been linked to cancer in some studies, although the scientific data remains controversial. The health risks associated with the use of glyphosate are still largely unknown.
A recent review by the World Health Organization’s International Agency for Research on Cancer concluded that glyphosate “is probably carcinogenic to humans.” However, further research is needed to assess its potential human health risks.
Other studies have explored the potential reproductive and developmental effects of glyphosate exposure, with some suggesting that it could cause birth defects in humans. While these claims remain largely unproven, it is important to note that many of the studies exploring these links were conducted on laboratory animals and may not be applicable to humans.
The long-term effects of glyphosate exposure are also unclear, and there is some evidence that it may cause genetic mutations in humans or animals.
Data accumulated in 2015 shows just how much Glyphosate is used around the world in agriculture in the production of higher-yielding crops. See the images below.

Is Glyphosate still effective?
Despite the controversy surrounding glyphosate, many people continue to use it for weed control. There are strategies for reducing your risk when using this herbicide, including wearing protective clothing and avoiding contact with the chemical when possible. It is also important to read the directions on the label and follow them carefully. This will help you ensure that you are using glyphosate safely and effectively.
As more research is conducted on the effects of glyphosate, it’s becoming increasingly clear that this chemical may not be as effective at controlling weeds over time as it once was.
In conclusion
Glyphosate remains a controversial topic, but it is clear that this herbicide can be an effective tool for controlling weeds. It is important to understand the science behind glyphosate, as well as the potential risks that come with its use. With this knowledge, you can make informed decisions about how and when to use glyphosate on your property or garden.
