An aqueous suspoemulsion (SE) comprising: a dispersed oil phase, Component (a), comprising: (i) lambda-cyhalothrin as the first active ingredient (ii) at least one solvent having lambda-cyhalothrin dissolved therein a continuous water phase, Component (b), comprising: (i) imidacloprid as the second active ingredient and (ii) water having imidacloprid suspended therein and optionally at least one additive selected from the group consisting of an anti- foaming agent, an emulsifier,an antifreeze agent, a dispersant, a preservatives antioxidant, colorant, a thickener and an inert filler. And a process for preparing an aqueous suspoemulsion as hereinbefore described, characterized in that it comprises: Step 1: Preparing lambda-cyhalothrin EC phase by mixing the active ingredient with a suitable solvent Step2 : Preparing a dispersion of imidacloprid in a continuous water phase by mixing the active ingredient, a dispersant and a required amount of water and Step 3: Combining the EC phase in Step 1 with the water phase in Step 2.
