Ecotoxicity of selected pesticides
Konečná, Veronika ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
Presented diploma thesis is focused on the ecotoxicological evaluation of insecticide mixtures Perfekthion and Bulldock 25 EC and their effective substances, dimethoate and beta-cyfluthrin, respectively. Dimethoate is an organophosphate insecticide while beta-cyfluthrin belongs to pyrethroids. Both mixtures’ target organisms are sucking and biting pests on grain crops, potatoes, vegetables, oilseed rape and ornamental flowers. Their application over large areas and transport in large volumes generates a significant risk of entering the environment. Mixtures and substances were tested on water plant Lemna minor, algae Desmodesmus quadricauda and crustaceans Daphnia magna and Thamnocephalus platyurus. The LC50, EC50, and IC50 values were determined and ecotoxicity of substances and mixtures was evaluated and compared.
