Diuron kills weeds by inhibiting the process of photosynthesis, this means that plants cannot convert sunlight energy to grow. It is absorbed by the plant via the root system.

Why is diuron being reviewed?
The active constituent diuron, product registrations containing diuron and associated label approvals are under review as part of the APVMA chemical review program. Diuron was selected for review because of concerns of potential environmental contamination of waterways as a result of diuron run-off from agricultural areas, particularly into marine environments. There were also some human health concerns about the toxicity of some impurities in the active constituent.
