Clofencet (Ref: MON 21250 )
Last updated: 15/01/2023
(Not known by any other names)
Clofenacet is a plant growth regulator mainly used on cereals. It is highly soluble in water, non-volatile and moderately persisten in soil systems. Based on its physico-chemical properties it is not expected to leach to groundwater. It has a low to moderate toxicity to most biodiversity. Its mammalian toxicity is low.
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.
