Residual Behaviour of Imidacloprid in Okra (Abelmoshusesculentus) and their Decontamination using Simple House Hold Process

Abstract
Field experiments were conducted at Agricultural University, Rajendra Nagar, Hyderabad, Telanagana to study the dissipation kinetics of Imidacloprid in okra fruit. Imidacloprid residues with one test dose at two spray i.e., first spray at flowering stage and second spray after an interval of ten days was carried out. The samples drawn at specific periods were analyzed by liquid chromatography and mass spectrophotometry (LC-MS/MS). The initial deposit of Imidacloprid in okra was found to be2.071mg/kg respectively. More than 98 % of Imidacloprid was dissipated after 15 days. These results are helpful in setting up maximum residual limit (MRLs) of Imidacloprid pesticide in okra in India. A decontamination study was conducted to evaluate quality of okra pods by reducing the residue of Imidacloprid by using different processes such as 2% salt solution, Acetic acid, Biowash, Butter milk, Cooking, Drying, Formula1(T7), Frying, Lemon water, Sodium bicarbonate, Tamarind water and Tap Water. From the results, it could be recommended that cooking suits best for almost all of the Imidacloprid residue. Sodium bicarbonate and 2% salt solution are the best methods for decontamination after cooking. The decontamination values of Frying and formula 1 seems to be almost same. After these two methods biowash thought to be the method of choice. Keywords - Okra, Biowash, Tamarind Water, Dissipation, Decontamination, Pesticide Residues
