Atrazine is widely used as a herbicide to control broadleaf and grassy weeds in various crops, including corn, sorghum, and sugarcane. It is applied to the soil before or after planting to prevent weed growth, ensuring better crop yields. Additionally, it is used in non-agricultural areas such as roadsides and railroad tracks to manage unwanted vegetation. Atrazine works by inhibiting photosynthesis in plants, effectively stopping their growth. Its persistence in the soil allows for long-term weed control, reducing the need for frequent applications. However, its use is regulated in some regions due to environmental concerns, particularly its potential to contaminate water sources.
