The present invention teaches a surfactant blend composition of at least one nonionic alkoxylate and at least one sugar-based surfactant, and its use as an adjuvant for pesticides. The pesticidal composition employing the surfactant blend composition of the invention realizes an efficacy that is unexpectedly superior to similar pesticidal compositions which employ only the individual surfactant components. The composition of the present inventionis useful as a tank side additive, or as a component in herbicidal formulations. In addition the compositions of the present invention are usefulas adjuvants for other pesticides, such as, fungicides, insecticides, plantgrowth regulators, acaracides and the like.
