Abstract
Following the application of Cypermethrin, fenvalerate and deltamethrin to a cauliflower crop at rates of 50, 50 and 12 g a.i. ha-1, the maximum initial deposits of these insecticides on heads and leaves were 1.10 and 0.75, 1.14 and 0.60, and 0.32 and 0.12 mg kg-1, respectively. These residue values for fenvalerate were less than the maximum residue limit (MRL) of 2 mg kg-1 for this crop. While the maximum initial deposits of Cypermethrin and deltamethrin on cauliflower leaves were less than their respective MRL values of 1 and 0.2 mg kg-1 for brassica leafy vegetables, it took one day for their residues on cauliflower heads to decline below this level.
