While glyphosate may be the most commonly used herbicide to treat for invasive weeds in the United States, close behind is another herbicide known as Atrazine. Because glyphosate has been so widely used, crops and plants have adapted over time to become more resistant to glyphosate and thus, atrazine was formed to battle against those resistant plants. In fact, many agricultural experts recommend mixing atrazine with glyphosate to combat glyphosate-resistant plants.

Solutions Pest & Lawn is proud to have in stock herbicides which contain Atrazine. On this page, you can learn some interesting facts about this herbicide, how it came to be and how it works as well as shop our line of atrazine-based herbicides.

What Is Atrazine?

Atrazine is a herbicide from the triazine class of herbicides and is the second most widely used herbicide in the US, with nearly 80 million pounds of atrazine used yearly. Atrazine plays an important part in the agricultural industry. Atrazine provides successful results as a pre-emergent and as a post-emergent and is primarily used to control broadleaf and grassy weeds that invade crops such as sorghum, corn, sugarcane, pine among others important plants.

Atrazine was first invented in 1958 by Geigy laboratories as the second of a series of 1,3,5-triazines, the herbicide is now manufactured primarily by Syngenta. Atrazine is most widely used on corn in the U.S., especially in the Midwest, but it's also used on crops like sugarcane, pasture grasses, and winter wheat.

Aside from the benefits, it brings to agricultural farmers, atrazine can also be used for residential weed control to improve the aesthetics of lawns. Atrazine is a popular weed control tool because it is economical to use, extremely effective against a spectrum of weeds, and very safe to the crop. Research has documented the benefits of atrazine to the bottom line for growers:

How Atrazine Works

Atrazine works by interfering with photosynthesis, especially inhibiting photosystem II. Photosynthesis— unique to green, living plants—happens when light energy is converted to chemical energy needed for food production. Simply put, when food production stops, plants eventually starve to death. Atrazine selectively kills non-desirable plants (weeds). This interferes with product growth and causes the plant to die. Atrazine works as both a pre-emergent when applied to the soil and post-emergent onto the grown plants themselves making it quite a versatile herbicide. It also eliminates weed competition, making all the soil nutrients and moisture go to the crop rather than the weed.

The fact that it the product is a selective herbicide, meaning it could kill weeds without injuring the crop, has made it exceptionally popular among the agricultural industry.

Is Atrazine Safe To Use?

Atrazine is one of the most carefully studied and thoroughly tested chemicals in the world. Nearly 7,000 scientific studies conducted over more than 50 years have clearly established its safety for humans and the environment.


With that being said, atrazine has been subject to a lot of controversy over its safety and its appearance in drinking water. While atrazine is toxic to mammals, birds and fish, atrazine has no impact on human health in real world exposure.


According to the EPA, atrazine and other triazine related herbicides pose "no harm" to "the general U.S. population, infants, children … or other major identifiable groups."


Syngenta, the manufacturer of atrazine, states that: No one ever has, ever will, or ever could ingest enough atrazine in drinking water to adversely affect their health. It is not physically possible to dissolve enough atrazine in water to have any health impact.
