Hygienic assessment of peculiarities of pesticides applied for chemical protection of sugar beet

摘要

Research has been carried out to determine the actual concentration of tefluthrin, S-metolachlor, lambda-cyhalothrin, propiconazole, cyproconazole, fluazifop-p-butyl in soil, sugar beet tops and roots after application of DUAL GOLD 96 EC (1.6 L ha~(-1)1), FORCE 1.5 G (15 kg ha1), FORCE 200 SC (30 mL/one seeding unit), FUZILADE 15 EC (2.0 L ha1), KARATE ZEON 5 SC (0.15 L ha~(-1)), ALTO SUPER 33 EC (0.7 L ha'1) in the chemical protection system. Degradation constant (K) of applied pesticides and quantitative parameters of persistence (t_(50), t_(95)) have been calculated in soil and sugar beet. Method of gas-liquid chromatography (GLC) has been used for determination of active ingredients and no residues revealed at the time of harvest.
