Abstract Turfgrasses exhibit significant potential for the phytoremediation of pesticide residues. However, the understanding of their phytoremediation capabilities remains limited. This study aimed to investigate the factors influencing phytoremediation behavior, including pesticide types, concentration, exposure duration, and plant species. Three common cool‐season turfgrass species— Lolium multiflorum Lam. (annual ryegrass), Lolium perenne L. (perennial ryegrass), and Festuca arundinacea Schreb. (tall fescue)—were utilized to assess their effectiveness in removing three residual pesticides (paclobutrazol, imidacloprid, and imazethapyr) from contaminated environments. The results indicated that the phytoremediation capabilities of turfgrasses are species‐specific, with a notable preference for certain residual pesticides. Annual ryegrass exhibited a higher removal rate for residual pesticides than perennial turfgrass, which correlated with its enhanced transpiration rate. Specifically, annual ryegrass demonstrated superior efficiency in remediating residual paclobutrazol compared to imidacloprid and imazethapyr. Correlation analysis further identified the translocation factor as a critical determinant of difference in removal rate. These findings offer valuable insights for optimizing the application of turfgrasses in the remediation of pesticide‐contaminated environments.
