Phenylformamidine derivatives are well known as insecticides for their specific activity against the insects. It has now been established that they show insecticidal activity as agonists on the octopamine receptor. In order to get a highly active compound we have intensively exploited fluorine substituted-aromatic formamidines possessing N-dialkylaminosulfeny group. Up to now, there are several candidates we found: N-(dialkylamino)sulfenyl-N-methyl-N'-(4-fluoro-2-methylphenyl)formamidines. The miticidal activity of Compound 29 show five-fold higher than Amitraz.
