A field experiment was carried out at Kalliyoor panchayat to determine the persistence and dissipation of the insecticide mixture thiamethoxam 12.6% + lambda cyhalothrin 9.5% ZC @ 33+15.75 g a.i ha-1 in tomato. The mean initial deposit of thiamethoxam and lambda cyhalothrin were 0.07 and 0.06 mg kg-1 and both reached the limit of quantification three days after spraying with half –lives 4.05 and 3.42 days respectively. Risk assessment studies using the dissipation data ensured the safety of the insecticide mixture sprayed product to the consumer. The residue analysis was carried out by LC- MS/MS and GC-ECD.
