A field experiment was conducted at Kalliyoor Panchayath of Thiruvanathapuram district to assess the dissipation and risk assessment of spiromesifen 22.9 % SC in chilli. The residue analysis conducted at Pesticide Residue Research and Analytical Laboratory at College of Agriculture, vellayani, Thiruvanathapuram revealed that, the insecticide had an initial residue of 0.92 mg kg-1. The half- life of spiromesifen on chilli was calculated as 4.49 days. Spiromesifen reached below LOQ on 15th day after spraying. Risk assessment studies revealed that the TMRC value less than that of MPI, indicated the safety of particular chemical.
