Effect of the insecti- and nematicide Poncho Votivo on hydrobionts of different systematic groups
Microbiological method of agricultural pests control involves usage of viruses, bacteria, fungi, and protozoa. Bacterial insecticides have been firmly established in the practice of controlling many pest species in agriculture and successfully compete with chemical plant protection products. The main advantage of biological agents is their complete safety for the environment and animals. They are not phytotoxic, do not accumulate in plants, and quickly decompose in the soil. Toxicological effect of insecti- and nematicide Poncho Votivo, CS on hydrobionts of different taxonomic groups: microalgae (Scenedesmus quadricauda (Turpin) Brébisson), macrophytes (Anacharis canadensis (Michaux) Planchon, 1848), molluscs (Planorbarius corneus (Linnaeus, 1758)), and embryos and fry of the round goby (Neogobius melanostomus (Pallas, 1814)), has been evaluated. During the experiment, the conditions of intoxication were simulated and toxicometric indicators for hydrobionts of different trophic levels were calculated. For each test subject, threshold and inactive concentrations of the preparative form of Poncho Votivo, CS were experimentally established. The research results allowed to identify the link that proved the most sensitive to the studied insecti- and nematicide.
