The aim of this study was to assess the efficacy of imazamox for control of and to assess the effects of plant decomposition on environmental indicators after application of this herbicide in microcosm conditions. The following rates were used: 600, 700, 800 and 900 g ai ha and spray volume 50 L ha. Control efficacy was determined as the percentage (from 0 to 100%) of visible injury symptoms in the plants, biochemical and chemical oxygen demand (BOD and COD), water quality variables, chlorophyll and pheophytin at 0, 7, 15, 30, 45 and 60 days after application (DAA) and fresh and dry biomass at 60 DAA.

The herbicide rates used were 600, 700, 800, and 900 g ai ha and spray volume of 50 L ha in electrostatic application. Control effectiveness was assessed at 7, 15, 30, 45, and 60 days after application (DAA), expressed in percentage (0-100%) of visible injury symptoms in the plants, biochemical oxygen demand (BOD), chemical oxygen demand (COD), chlorophyll and pheophytin contents at 0, 7, 15, 30, 45, and 60 DAA, and fresh and dry biomass at 60 DAA.

- The research aimed to assess the effectiveness of copper oxychloride, copper hydroxide, and diquat in controlling two types of algae: the unicellular Ankistrodesmus gracilis and the filamentous Pithophora kewesis, while also evaluating the acute toxicity of these chemicals on certain non-target aquatic organisms.
- Both copper sources demonstrated high efficacy against A. gracilis, achieving over 95% control at low concentrations, while diquat alone and with copper hydroxide also showed strong effectiveness.
- However, none of the chemicals significantly affected P. kewesis, and among the non-target organisms, Lemna minor was the most sensitive to the treatments, while Hyphressobrycon eques was the least affected.
