Abstract: The present study was carried out to investigate the potential activity of abamactin, locally formulated as 8.4 % SC. The prepared formulations physical and chemical properties were performed with comparison to Agremic Gold 8.4 % SC at different accelerated storage conditions to predict the stability of the formulations. Moreover both were evaluated their toxicity studies (lethal concentrations) against adult T. urticae under laboratory conditions. Different parameters, pH, free acidity, viscosity, density, specific gravity, surface tension and persistent foam were determined. The local formulation exhibited good stability initially and at different storage conditions. The effect of the local formulation on two-Spotted spider mite, Tetranychus urticae tested under laboratory conditions with comparison to the recommended acaricide Agremic gold 8.4 % SC. The results showed that the prepared formulation had competitive acaricidal activity against two-Spotted spider mite, Tetranychus urticae. The LC50 of the locally prepared formulation recorded 0.0141 ppm, where it was 0.0102 ppm for Agremic gold. The toxicity index of the locally prepared formulation was 72.43 % rather than Agremic gold.
