Abstract: This study was performed in order to determine toxic effects of different doses of Attribut (propoxycarbazone-sodium) used in wheat fields and BioPower (sodium alkyl ether sulphate) surfactant added to Attribut on Triticum aestivum L. ‘Pehlivan’. The doses used in the study were 0.42 mM Attribut, 0.82 mM Attribut, and 1.68 mM Attribut with or without 0.25% BioPower. Laboratory studies showed that the effective concentration value corresponded to the farmer dose, 0.42 mM Attribut. Applications were done by seed treatment. The effects of each of the doses applied to wheat plants were monitored in terms of anatomical parameters. Attribut doses of 0.82 mM and above had toxic effects on wheat plants, and these effects increased with the use of BioPower. As a response to the stress, the diameter in the general structure of the roots narrowed, the cuticle thickened, cleavages in parenchyma cells developed, and cell walls in the sclerenchyma cells and endodermis thickened.
