Di-allate (Ref: CP 15)
Last updated: 11/03/2022
(Also known as: diallate)
Di-allate is a pre-emergence herbicide. It has a low aqueous solubility but is miscible with many organic solvents. It is volatile and expected to be moderately persistent in soil systems. Di-allate is moderately toxic to mammals, carcinogenic and a recognised irritant. It is moderately toxic to fish but little data is available regarding its toxicity to other species.
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.
