Flutianil (Ref: OK-5303)	Last updated: 17/01/2023
(Not known by any other names)

SUMMARY

Flutianil is a horticultural fungicide. It has a very low solubility and is volatile. It is persistent in soils. It has a low mammalian toxicity but there are some concerns regarding effects on reproduction and carginogenicity. It exhibits moderate to low toxicity to most aquatic and terrestrial organisms.
