Atrazine

Atrazine is a selective, systemic herbicide belonging to the triazine chemical group, widely used for controlling annual broadleaf weeds and certain grass weeds in agricultural crops. It works by inhibiting photosynthesis in susceptible plants and is primarily used in maize, sorghum and sugarcane cultivation. Depending on national registrations, its applications may extend to other crops. In India, atrazine is registered for specified uses in maize and sugarcane, subject to crop-specific application requirements.

Atrazine is commonly applied as a pre-emergence herbicide or an early post-emergence treatment to manage weed competition during critical crop growth stages. However, its use has faced regulatory scrutiny over groundwater contamination, surface-water runoff, aquatic ecosystem exposure and potential human health risks. The European Union banned atrazine in 2004 after concerns about groundwater contamination and the inability to demonstrate that groundwater concentrations would remain below the prescribed limit. The herbicide continues to be permitted for specified agricultural applications in countries such as India and the United States, although regulatory reviews and restrictions remain important areas of debate.

This section covers the latest Atrazine news, including herbicide bans, pesticide restrictions, regulatory reviews, registrations, scientific research and developments in weed management. Coverage also follows atrazine residue monitoring, groundwater contamination, environmental risk assessments, herbicide resistance management and its role in maize and sugarcane production. Updates examine decisions by pesticide regulatory authorities, including India’s CIB&RC, the US EPA and international regulators.
