Trifludimoxazin
(Not known by any other names)
SUMMARY
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 idenified.
