Abstract

In the present study, triazophos dissipation was observed on chilli, the residues of triazophos on human beings were assessed, and a waiting period was suggested for safety reasons for consumers. After applying triazophos (Truzo 40 EC) at 500 g a.i.ha-1, we found that initially 1.19 mg/kg of triazophos was accumulated on average. With the recommended dosage, the residues dissipated below the limit of quantification (LOQ, 0.05 mg/kg) in 10 days. The dissipation of triazophos in chilli followed first-order kinetics. Based on the calculations, the half-life is 2.18 days for recommended dosage. A waiting period of 12 days is suggested for the consumption of chilli sprayed with triazophos at the recommended dosages.

Conclusion

Half-life values for triazophos on chilli at the recommended dosage were observed to be 2.18 days. A waiting period of 12 days is suggested to reduce the risk before consumption of chilli. The residues of triazophos were found to be eliminated after 15 days. Therefore, it is recommended to wait for 15 days before harvesting and consuming chilli after the application of triazophos.
