Ketospiradox is a chemical herbicide. A triketone and aroylcyclohexanedione herbicide, it is a 4-hydroxyphenylpyruvate dioxygenase inhibitor that causes bleaching in broadleaf and grass weeds. Its formula is C20H21O7S.

Uses

Ketospiradox is a synthetic herbicide. It does not have an ISO common name, and was given its current name by the Weed Science Society of America in 2010. The herbicide is applicable to maize, asparagus, and sweetcorn, among other crops, but is not approved for use in the United Kingdom or any European Union member states.
