Dissipation Pattern of Chlorpyriphos, Cypermethrin, Ethion, Profenophos and Triazophos in Curry Leaf

Studies were conducted for determining the residues of Chlorpyriphos, Cypermethrin, Ethion, Profenophos and Triazophos in Curry leaf which were detected the most in market samples by conducting field experiments after spraying twice during 2015 - 2016 and analyzed using QuEChERS method on LC-MS/MS. As there are no MRLs for curry leaves, it should be considered as most important to fix MRLs to ensure food safety and consumer health and to create awareness among the farmers about the application dose, method of application and Pre-harvest Intervals. The mismanagement or non-availability of proper information about the pesticide application can lead to contamination of pesticide residues in curry leaf. The findings of this study provided important data on dissipation of pesticide residues in curry leaf and hence, it is essential to conduct dissipation studies in other curry leaf growing agro climatic regions, which may serve as basis for future policy about the standards and quality control of pesticides.
