Atrazine is a widely used herbicide primarily for controlling weeds in crops like corn and sugarcane. It works by inhibiting photosynthesis in plants, effectively preventing their growth. Atrazine is applied to fields before or after planting to manage unwanted vegetation. This chemical is one of the most common pesticides found in groundwater in the United States. While it helps increase agricultural productivity, concerns have been raised about its potential environmental impact and effects on human health. Regulatory agencies monitor its use to ensure safety and minimize risks associated with its application.
