Bromacil (Ref: DPX N0976)
Last updated: 15/03/2023
(Also known as: borocil; herbicide 976)
Bromacil is a soil acting uracil herbicide which is is used to control both annual and perennial weeds, although some essential uses may be authorised. It is highly solublein water and many organic solvents. It is not considered volatile. It may be persistent in soil and water systems depending on local conditions. Theres is also concerns regarding its potenrial to leach to groundwater. It tends to demonstrate a low to moderate toxicity to most fauna and flora. Iit has a moderate mammalian oral toxicity and no other serious human health concerns have been identified.
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.
