Tomatoes are widely consumed across the globe and are key ingredients in many cuisines all over the world. This ensures high demand year-round which can challenge suppliers to satisfy profitably. Tomatoes suffer a range of pests and diseases which especially need to be controlled in enclosed growing environments such as glass houses, used extensively in northern latitudes.  A wide range of plant protection products may be applied to tomatoes at all stages of plant growth as well as post-harvest protection.  As a result, tomatoes are annually included in government monitoring schemes due to the high frequency of residues detections.

This proficiency test is specifically for a range of pesticide residues that are generally determined using specific single-residue methods.  The majority of pesticide residues are determined using multi-residue methods, that is ones in which potentially hundreds of compounds can be measured with a single extraction protocol and instrumental method, based on multi-stage mass spectrometry.  However, some pesticides are not very amenable to the generic multi-residue approach and still require more specific extraction regimes and chromatographic-mass spectrometric approaches.  This one PT has a fixed list of such pesticides for determination by single residue methods.  Not all the pesticide residues need to be determined.
