Fluensulfone (Ref: BYI 01921)
Last updated: 01/09/2023
(Also known as: MCW-2)
Fluensulfone is an agricultural and horticultural nematicide. It has a moderate oral toxicity and low by dermal and inhalation routes. It is an irritant and skin sensitiser. It can be expected to dissipate rather rapidly in the environment and has a low to moderate toxicity to fauna and flora.
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.
