In a field study carried out at three different locations, the dissipation of spiromesifen on cotton and chili was studied and its DT50, and DT99 were estimated at each location. Spiromesifen was sprayed on chili at 96 and 192 g a.i. ha(-1) and cotton at 120 and 240 g a.i. ha(-1). Samples of chili fruits were drawn at 0, 1, 3, 5, 7, 10, 15, 21, 30 days after treatment and that of cotton seed and lint at first picking and harvest. Soil samples were drawn 30 days after treatment from 0 to 15 and 15 to 30 cm layer. Quantification of residues was done on GC-MS in Selected Ion Monitoring (SIM) mode in mass range 271-274 m/z. The LOQ of this method was found 0.033 microg g(-1), LOD being 0.01 microg g(-1). The DT50 of spiromesifen when applied at recommended doses in chili fruits was found to be 2.18-2.40 days. Ninety-nine percent degradation was found to occur within 14.5-16.3 days after application. Residues of spiromesifen were not detected in cotton seed and lint samples at the first picking. In soil, no residues of spiromesifen were detectable 15 days after treatment.
