Abstract:
The persistence and dissipation behavior of deltamethrin in/on sapota fruit under South Gujarat condition was investigated by using gas chromatography with electron capture detector (GC-ECD) after QuEChERS based extraction procedure. The linear dynamic range of deltamethrin in sapota fruit matrices was obtained between 0.01 to 0.1 µg/g. The recovery of deltamethrin in sapota fruit ranged from 98 to 101%. The relative standard deviation (RSD) ranged from 1.59% to 5.66%. The half-life of deltamethrin in sapota fruit were ranged from 1.74 and 2.19 days for recommended dose (28 g a.i./ha) and 1.83 and 2.00 days for double to recommended dose (56 g a.i./ha) for the year 2019-20 and 2020-21. The waiting period (WP) of deltamethrin ranges from 4.69 - 5.01 days under South Gujarat conditions. The dietary risk quotient (RQ) was found < 1 which signifies that sapota fruits collected from the field was safe for consumption of Indian population.
