Abstract

The dissipation patterns of acephate in bitter gourd fruits were studied after the application of acephate at the fruiting stage. Acephate was applied at the rate of 560 g a.i/ha on bitter gourd fruits and the fruit samples were collected at the 0, 1st, 3rd, 5th, 7th, 10th, 15th, 21st, 25th, and 30th day after spray. The initial deposits of acephate in bitter gourd fruits from the treatment (T1) was 0.229 mg/kg with a half-life of 2.35 days. Based on the persistence studied waiting period of 7 days is suggested for acephate on bitter gourd from a consumer safety point of view.

Conclusion

The dissipation of Acephate in bitter gourd fruits followed first-order kinetics. Half-life values for Acephate on bitter gourd at the recommended dosage were observed to be 2.35 days. The residues of Acephate were found to be eliminated after 7 days. Therefore, it is recommended to wait for 7 days before harvesting and consuming bitter gourd after the application of Acephate.
