Abstract:
A field experiment was conducted at Rajasthan Agricultural Research Institute, Durgapura, Jaipur during Summer, 2022 to study the persistence of lambda-cyhalothrin residues in the soil of okra field, when sprayed at its recommended dose (lambda-cyhalothrin 15 g. ha-1) and double of the recommended dose (lambda-cyhalothrin 30 g. ha-1). The samples were extracted and cleaned up using a modified QuEChERS method and the residues were analyzed by GC-ECD. The residues level of lambda-cyhalothrin in okra field soil collected at harvest time of okra crop were below the detectable level (BDL) at the recommended dose and double of the recommended dose, respectively.
