Abstract: A laboratory study has been experimented to determine the persistence nature of a new ready mix fungicide formulation (tricyclazole 33.3% + azoxystrobin 16.7%) SC in both aqueous systems of different pH and soil samples collected from four different agro climatic regions at single dose (T1) of 1 ppm and double dose (T2) of 2 ppm of each active ingredient under laboratory simulated condition. All samples were collected at specific interval after treatments and processed for residue analysis of both tricyclazole and azoxystrobin. Extraction and clean up procedure was developed and their residue were analyzed by LC-MS/MS. The recovery % of both analyte in every case was 85% or more than that. Dissipation was approximated to first order kinetics in every condition. It is seen that the degradation nature of both of the compound were quicker in alkaline condition followed by neutral and least in acidic condition.
