 |
(Also known as: bromfenuron; N'-(4-bromophenyl)-N,N-dimethylurea) |
Bromuron is a urea herbicide. It has a moderate aqueous solubility and a low volatility. Depending on local condition it may be persistent in soil systems. Little information has been reported regarding its toxicity to biodiversity. It has a moderate oral toxicity to mammals. |
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
