Pyridat Chemical Properties, Uses, Production
Uses
Herbicide.
Uses
Pyridat, which is a herbicide used in agriculture. Pyridat has been used to control annual broadleaved weeds in sweet corn, cauliflower, broccoli and leek.
Definition
ChEBI: Pyridate is a member of pyridazines.
Production Methods
Pyridate is commercially produced via a multi-step process starting with the condensation of phenylhydrazine and mucochloric acid to form 4,5-dichloro-2-phenylpyridazin-3(2H)-one, followed by selective nucleophilic substitution of the 4-chloro group with O,O-diethyl thiophosphoryl chloride under basic conditions to yield the active O-(6-chloro-2-phenyl-3(2H)-pyridazinon-4-yl) O,O-diethyl phosphorothioate core.
Hazard
Moderately toxic by ingestion and skin contact.
Trade name
CL-11344®; LENTAGRAN®; PIRATE®; ST-9551®; TOUGH®
Mechanism of action
Selective with contact action, absorbed mainly by the leaves. Photosynthetic electron transport inhibitor at the photosystem II.
Pesticide Type
Herbicide
