Quantifying residues of insecticide applied for management of brinjal shoot and fruit borer

  • M.M. Rahman, M.R. Ali


The experiment was undertaken to detect and quantify carbosulfan residues on brinjal fruit with comparison with maximum residue level (MRL) recommended by Food and Agricultural Organization (FAO). Carbosulfan was applied at the recommended rate of 1.5 ml·L-1 and the elevated rate of 3.0 ml·L-1 of water under tropical conditions.  Samples were collected at different days after treatment (DAT) to determine presence, and degradation of, residues. A residue above the MRL was detected up to 3 DAT for the 1.5 ml·L-1 rate and 10 DAT for 3.0 ml·L-1 rate. Degradation shortly after application proceeded more slowly, but the rate of degradation increased over time. Carbosulfan is still legal for use on brinjal and it should not be applied above 1.5 ml·L-1 and the pre-harvest interval should not be less than 7 days.
