Advances in the Technology for Controlled-Release Pesticide Formulations
The choice of formulation is influenced by the following factors: the physical properties of the pesticide (melting point, solubility, and volatility), the chemical properties of the pesticide (hydrolytic stability, thermal stability, and irradiation stability), the mode of application of the formulation (soil, foliar), the crop to be treated and the agricultural practices, the biological prope...
متن کاملHPLC Determination of Oxadiazon in Commercial Pesticide Formulations
Um procedimento simples, rápido e preciso de cromatografia líquida de alta eficiência (HPLC) foi desenvolvido para a determinação de oxadiazona em formulações concentradas de pesticidas emulsificáveis. 20 μL de amostra, diluída em acetronitrila, foram injetados em uma coluna Kromasil C18 (250 × 4,6 mm, 5 μm), usando acetonitrila:água (80:20) como fase móvel, numa velocidade de fluxo de 1 mL min...
متن کاملDialyzability of Surfactants Commonly Used in Pesticide Formulations
Objective: This study aimed to determine the dialyzability of common pesticide surfactants. Methods: Hemodialysis and hemoperfusion were performed for three surfactants-sodium dodecylbenzenesulfonate, lignosulfonic acid sodium, and naphthalenesulfonic acid polymer with formaldehyde-with buffer solutions (2 L) containing 0.2% surfactant with or without bovine serum albumin (3.0 g/dL). Results: T...
متن کاملFourier Transform Infrared Determination of Imidacloprid in Pesticide Formulations
Foi desenvolvido um método simples usando Infra-Vermelho com Transformada de Fourier (IRFT) para a determinação de Imidaclopride em formulações pesticidas. As amostram foram diluídas com CHCl 3 e os espectros de IRFT de amostras e padrões foram obtidos numa resolução nominal de 4 cm, entre 4000 e 900 cm, com acumulação de 25 espectros. A determinação de Imidaclopride foi feita medindo-se tanto ...
متن کاملFormation of dioxins during exposure of pesticide formulations to sunlight.
Chlorinated pesticides can contain impurities of dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), and their precursors, as a result of various manufacturing processes and conditions. As precursor formation of PCDD/Fs can also be mediated by ultraviolet light (UV), this study investigated whether PCDD/Fs are formed when currently used pesticides are exposed to natural sunlight. Formulations contai...
