Relative Pesticide Residue in Chilli (Capsicum annum L.) Plant Parts at Different Growth Stages

Study was conducted to evaluate the presence of crop protective agents in chilli crop at different growth stages and at different plant parts. From the study it is found that presence of Organophosphorous, synthetic pyrethroids and strobilurin molecules were found in the samples of chilli plant parts in all the growing stages when analysed with GC MS/MS. The concentration of the molecules are in descending order of Triazophos greater than Permithrin total greater than Deltamithrin greater than Ethion greater than Cypermithrin total greater than Chloripyriphos ethyl greater than Trifloxystrobin in chilli shoot. Molecules of Triazophos and Ethion were found in the roots of chilli. Pesticide residues of triazophos, ethion and trifloxystrobin were found in chilli fruits and the residue concentration in the chilli fruits were higher than the EU MRL. From the residue data of green chilli fruit samples, consumption is hazardous to humans and not recommended as the TMRI (Theoretical maximum residue concentration) residue level (0.2264 mg/person/day) crossed the MPI (Maximum Permissible Intake) in triazophos (0.06 mg/person/day), considering average daily consumption of green chilli is 50g per person per day.
