Abstract
Insecticides are used on grapevines in order to eradicate the insects which cause huge economic losses to growers. Hence, residues are explored during field trial in order to check their stability as well as dose effects. Current research was designed for two grape varieties using 3 doses of acetamiprid where sampling intervals followed were (2hr after spray) 0th day, 3rd day, 7th day, 15th day, 20th day, 25th day, 30th day, 33rd day and 35th day while fruit on vine. Acetamiprid residues (mg Kg-1) disappeared from 7.409±0.215 to 0.066±0.003 at RD, 12.974±0.966 to 0.039±0.002 at DD while 20.263±0.932 to 0.017±0.002 at TD in perlette grapes. But in black grape residues (mg Kg-1) disappeared greatly with degradation from 7.354±0.63 to 0.027±0.001 at RD, 13.091±0.276 to 0.014±0.001 at DD and 20.045±1.094 to 0.04±0.003 at TD, respectively. Moreover, mathematical model was applied where allied statistical indices and parameters were calculated subsequently.
