Anilofos is an organophosphate herbicide used to control annual grass weeds and sedges. It has a low aqueous solubility and a low volatility. It may be moderately persistent in soil systems depending on conditions. It moderately toxic to fish, aquatic invertebrates and honeybees but less so to birds. Anilofos is moderately toxic to mammals via the oral route. It is also a neurotoxin and a recognised irritant.
Data alerts
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.
