This study was aimed to evaluate the role of Potassium silicate, humic acid, and salicylic acid in both normal and Nano sizes in eliminating Tetranychus urticae Koch infestations on the eggplant cultivars Jawaher, Barcelona, and Iraq wonder. Potassium silicate was used by 2.5 ml/L and 5 g/L, humic acid 10 ml/L and 20 g/L and salicylic acid 0.1 g/L and 0.2 ml/L for ambient and Nano size respectively, the treatment plants were observed weekly after application to determine the population density of TSSM .The use of prior fertilizers reduces the population density of TSSM as compared to the control treatment in all three cultivars. SEM pictures revealed that the potassium silicate Nano capsule (PSNC), humic acid Nano capsule, and salicylic acid Nano emulsion had diameters of 99, 92, and 26 nm, respectively. The zeta potential values for potassium silicate Nano capsule, humic acid Nano capsule, and salicylic acid Nano emulsion were -68.2, -43.5, and 63.1 mV, respectively.
