Popis: Pesticides are widely employed to boost the production of vegetable crops, but their indiscriminate application leaves residue in the crops for long, even after harvesting. Among pesticides, neonicotinoids are the most commonly applied group of insecticides which are used on vegetables to defend against a variety of sucking pests. The purpose of this study was to validate an analytical approach focused on QuEChERS extraction for the validation and simultaneous determination of residues of four neonicotinoids (imidacloprid, clothianidin, acetamiprid and thiamethoxam) in six diverse crops such as cucumber, brinjal, tomato, beans, cabbage, and cauliflower. Insecticides were quantified using high-performance liquid chromatography (HPLC) fitted with a UV-Vis detector. Specificity, linearity, precision, accuracy, limit of detection, and the limit of quantification were all considered for validation. The fortification of the vegetables was done at three different levels (0.2, 0.3 and 0.5 µg mL
