A method for determination of chlorofenapyr residues in squash by HPLC is described. Samples were extracted with methanol/water, followed by liquid-liquid partitioning and clean-up in chromatographic column, concentrated to a small volume. Analysis was then determined by HPLC equipped with UV-vis detector at 260 nm. The degradation rate of chlorfenapyr SC was studied and the results indicated that final residue in squash leaves reached 0.1 mg/kg after 14 day and was undetected for the fruits, which was considered safe for human beings and animal consumption.
A method for determination of Fenpyroximate (Ortus) (5%) residues in eggplant (Solanum melongena L.) by HPLC is described. The analysis was done using HPLC equipped with a UV-Vis detector at 254 nm. The degradation rate of Fenpyroximate was studied and the results indicated that final residue in eggplant reached 20.1% after 21 days which was considered safe for human and animal consumption, despite its insecticide effectively on eggplant pests.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
