Meptyldinocap (Ref: DE 126)
Last updated: 14/11/2021
(Also known as: GF-1478)

SUMMARY
Meptyldinocap is a protectant, curative and eradicant fungicide. It has a low aqueous solubility, it is volatile and, based on its chemical propoerties, is unlikely to leach to groundwater. It is not persistent in soil and will usually degrade in water systems quickly. It is modertaely toxic to mammals and bioaccumlation may be a concern. Whilst it is not highly to toxic to birds is is toxic to many aquatic species including fish and algae.
