Abstract

A field study was conducted during the 2020/2021 agricultural season to show the effect of salicylic acid on the resistance of some eggplant varieties to the two spotted spider mite Tetranychus urticae (Koch). The study results showed that the two spotted spider mite Tetranychus urticae Koch accompanied the eggplant crop during the agriculture season, and the significant effect of the single coefficients of eggplant varieties, salicylic acid concentrations, sampling dates in the severity and percentage infestation of the two spotted spider mite were recorded, the 0.5 mM concentration showed high efficiency in controlling of the severity and percentage infestation of the two spotted spider mite, reaching aminimum of 28.86 and 36.65%, respectively, while the control treatment was characterized by the highest severity and percentage infestation, reaching 35.48 and 46.47%, respectively.
