Abstract:
A field experiment was conducted at Rajasthan Agricultural Research Institute, Durgapura, Jaipur during Kharif, 2020 to study the persistence of spiromesifen residues in the soil of chilli field, when sprayed at its recommended dose (spiromesifen 96 g. ha^-1) and double of the recommended dose (spiromesifen 192 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 spiromesifen in chilli field soil collected at harvest time of chilli crop were below the detectable level (BDL) at the recommended dose and double of the recommended dose, respectively.
