| Description | Quizalofop-p-ethyl ((R)-Quizalofop ethyl) is a selective post-emergent herbicide for use on annual and perennial weeds, acting as an acetyl-CoA carboxylase (ACCase) inhibitor leading to weed death. |
| In vitro | Quizalofop-p-ethyl (0.5–5 mg/L, 3–6 days) interferes with photosynthesis in Microcystis aeruginosa by downregulating photosynthesis-related genes psaB and psbD1, and upregulates mcyH expression, thereby promoting the synthesis and release of microcystin-LR (MC-LR)[1]. |
| In vivo | Quizalofop-p-ethyl (0.5–5 mg/L, 6 days) significantly inhibits the growth of M. aeruginosa, reducing its chlorophyll a and protein content. Short-term exposure (0.5–5 mg/L, 24–48 h) increases MDA content and enhances SOD and CAT activities, triggering oxidative stress responses in algal cells[1]. |
