Abstract:  Some O-alkyl 0-(2-methoxyethyi, 2-ethoxyethyl) 0-(l,5-di-R-6-oxo-1 H-pyridazin-4-yl) thiophosphates were synthesized and tested for contact and systemic insecticidal, acaricidal, ovicidal, and fungicidal activities. The highest activity was found with О-ethyl 0-(2-methoxyethyl) 0-(5-methoxy-l-methyl-6-oxo-lH-pyridazin-4-yl) thiophosphate. The antipowdery mildew activity of this compound on E. graminis was several times higher than that of the used standard Chloraniformethane.
