| Hazard Information | Back Directory | [Description]
Choridazon is a herbicide for broadleaved weeds and grass control. It has a moderate aqueous solubility and is not considered to be volatile. It is moderately persistent in soil system and can also be persistent in water systems under some conditions. It has a low oral mammalian toxicity and whilst it is a recognised skin and eye irritant no chronic health impacts have been identified. It shows moderate to low ecotoxicity to most species. | [Chemical Properties]

Herbicide, active by perturbing cell membranes | [Definition]
ChEBI: A pyridazinone that is pyridazin-3(2H)-one substituted by an amino group at position 5, a chloro group at position 4 and a phenyl group at position 2. | [Production Methods]
Chloridazon is synthesised through a multi-step organic process starting with phenylhydrazine or derivatives and chlorinated pyridazinone intermediates. The precise process does not seem to be in the public domain but general information suggests that it starts with cyclization that forms the pyridazinone ring via condensation reactions. Chlorination introduces a chlorine atom at the 4-position of the ring. An amination step adds the amino group at the 5-position. | [Mechanism of action]
Selective, systemic. Inhibits photosynthesis (photosystem II). | [Pesticide Type]
