Simazine solution is widely used as a selective herbicide in agriculture to control broadleaf weeds and grasses in crops such as corn, sugarcane, and fruit orchards. It is applied to the soil, where it inhibits photosynthesis in target plants, preventing their growth while sparing the crops. This makes it an effective tool for maintaining crop yields and reducing competition for nutrients. Additionally, simazine is used in non-agricultural settings, such as on railways, industrial sites, and in forestry, to manage vegetation and prevent unwanted plant growth. Its persistence in the soil allows for long-term weed control, reducing the need for frequent applications. However, careful handling and application are required to minimize environmental impact and avoid contamination of water sources.
