[Acaricidal, chemosterilant and insecticidal activity of triazine derivatives]

A large number of 1-aryl-3,3-dialkyl triazenes and 1,2-diphenyl triazenes variously substituted in the 3 position with OH and alkyl groups were prepared and studied for acaricide activity against Panonychus ulmi and chemosterilizing and insecticidal activity against Musca domestica. The results highlighted the marked chemosterilizing activity of 1-(2-methoxyphenyl)-3,3-di-n-propyltriazene and the interesting acaricidal activity of 1-(4-benzoylphenyl)-3,3-dimethyltriazene. The examination of such a large number of compounds for insecticidal activity allowed interesting conclusions to be drawn regarding structure/activity relationships.
