Isoflucypram (Ref: BCS-CN88460)	Last updated: 02/03/2024
(Not known by any other names)

SUMMARY

Isoflucypram is a new cereals fungicide. It as a low aqueous solubility and is not considered highly volatile. Under certain conditions the substance may be persistent in both soil and water systems. No major human health issues have been identified but it may be a skin sensitiser or cause skin irritation. It is toxic to aquatic systems but is not considered harmful to insect pollinators.

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.
