The study investigated the effect of the herbicide imazamox, which belongs to the class of ALS inhibitors, on the green microalga Desmodesmus armatus. A clear concentration-dependent effect was established: at low concentrations (0.01–0.1 mg/L), partial restoration of cell growth was observed, which may indicate the activation of compensatory mechanisms. In contrast, high doses (2.5–10 mg/L) led to rapid and sustained inhibition of cellular activity.
The results indicate a high sensitivity of D. armatus to imidazolinones and support the suitability of this species as a model organism for assessing the toxicity of herbicides that inhibit acetolactate synthase.
