In the USA diuron has been used since 1967. Durion is mainly used on citrus, berries, asparagus and pineapple. Right-of-way applications (e.g., the area around railroad tracks) are the greatest non-agricultural use of diuron, with approximately 1 million kilograms applied annually.

It's a stable molecule in terrestrial systems but can be biodegraded by micro-organisms. It is expected to be much less stable in aquatic systems, where it's concentration might be halved in 30 days (according to lab experiments).

It has a low toxicity for mammals, as doses above 3,4 g per kg body weight are needed to induce acute toxicity. Some fish and marine invertebrate species experience acute toxic effects at diuron concentrations above 4,3 mg/l and 1 mg/l respectively[3]. Algae are most vulnerable to the herbicide, it can be toxic for some algae species at concentrations of only 5 µg/l[4].
