Abstract


This paper reports the results of a study performed to investigate the potential of a thin layer chromatography (TLC) bioassay for detection of fungicidal residues on harvested fresh produce. A procedure for collection of fungicidal residues from the surface of fresh produce and detection using bioassay was developed. This method was subsequently applied successfully to detect and quantify fungicide residues in a commercial sample of tomato. The method is convenient, cost-effective, and sensitive enough for screening residues of known fungicides on fresh produce in laboratories with limited resources.

 

Key words: Fungicide residues, harvested produce TLC bioassay.
