Chloroneb is an obsolete fungicide seed treatment that was largely used on turf. It is no longer approved for use in the UK, EU or many other countries. It has a low aqueous solubility and is highly volatile and so may be prone to drift, It tends to be persistent in soil systems. It is not mobile and so will have little propensity for leaching to groundwater. It has a low to moderate toxicity to mammals, birds, fish and aquatic invertebrates. It is not highly toxic to humans but is considered to be a skin and eye irritant.
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.
