Dissipation Study of Difenoconazole in/on Chili Fruit and Soil in India

Abstract

One field experiment was conducted with Difenoconazole (25% EC) on chili crop during December 2009 to January 2010 at two different locations of West Bengal and Maharashtra. The main objective was to understand the residue and persistence behaviour of fungicide difenoconazole in chili fruit and soil samples. Difenoconazole was applied in chili field at 50 mL and 100 mL/100 liter of water. Its residue was analyzed by using LC–MS/MS and it dissipated in chili fruit and soil following first order kinetics. The half life values of difenoconazole were found in the range 2.15–2.32 days and 4.68–8.09 days for chili fruit and soil, respectively.
