Description
The article presents the results on the effects of Imazethapyr herbicide on aquatic organisms. The chronic toxic effects have been studied of the imidazolinone herbicide in a concentration range of 0.4 - 1150 mg/l to the representatives of various groups of aquatic organisms: zoobenthos – great ramshorn snail (Planorbarius corneus), zooplankton - Daphnia (Daphnia magna Straus), phytoplankton - protococcal alga (Scenedesmus guadrigauda) and macrophytes - higher aquatic vegetation (Elodea canadensis Michx). It is shown that the herbicide does not have a pronounced lethal effect to aquatic organisms tested. Their respective LC50 values are > 1000, 680, 510 and 910. Elodea is shown to be most sensitive to its sublethal effects (decreased growth of lateral and main sprouts at a concentration of 10 mg/l and more), reduced fertility was observed in Daphnia at a concentration of 300 mg/l and above, and as to the great ramshorn snail no sublethal effects have been revealed for all the concentrations studied
