Abstract
Abstract Pyridazinothionophosphoric (-phosphonic) acid esters which possess arthropodicidal, especially insecticidal or acaricidal, properties. The compounds have the structure IN WHICH R is a lower alkyl or phenyl radical, R1 is a branched or straight-chain lower alkyl radical, and R2 is a branched or straight-chain lower alkoxy or alkyl or phenyl radical.
