Abstract: The synthesis of 0,S-dialkyl 0-(l-R⁴ -5-R³ -6-oxo-lH-pyridazin-4-yl) thiophosphates (R⁴= alkyl, phenyl; R³ = alkoxy, alkylthio, chlorine) is de­scribed. All the prepared compounds were tested for contact and systemic insecticidal, acaricidal, and ovicidal activities. The pesticidal activity and toxicity of the mostly active compounds against warm-blooded organisms were compared to the activities of the corresponding 0,0,0-esters .
