A fast-acting herbicide used to control broad-leaved and grass weeds. Trifludimoxazin has a low aqueous solubility and a low volatility. It is not expected to be persistent in soils. It demonstrates a low toxicity to most fauna and flora. Trifludimoxazin has a low mammalian toxicity if ingested and no serious health implications have been identified.
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.
