(Also known as: diphenamide; diphenylamide; difenamide)
Diphenamid is a selective herbicide for annual grasses and some broad-leaved weeds. It is moderatly soluble in water and has a low volatility. It is expected to moderately persistent in soils. There are significant gaps in ecotoxicological data but diphenamid is highly toxic to aquatic invertebrates, moderately toxic to fish, and has a low avian and honeybee toxicity. The susbtance has a moderate oral mammalian toxicity.
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.
Environmental fate Moderate alert: GUS: Transition state; Drainflow: Moderately mobile
