Altogether 19 pesticide preparations were used according to agriculture practise within 6 trials in apple orchards. Using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods, premature Golden Delicious apples collected 64, 50, 36 days before harvest and matured fruit were examined for residues of active ingredients. No residues of triflumuron, triazamate, chlorpyrifos, etofenprox, fenoxycarb, kresoxim-methyl, cyprodinyl, difenoconazole and thiram were detected in the first sampling, also the levels of chlorpyrifos-methyl, penconazole, tebuconazole and tolylfluanid dropped during the pre-harvest interval. Although detectable, residues of pyridaben, thiacloprid, trifloxystrobin and tetraconazole in harvested fruits were below 0.01 mg kg-1 what is the maximum concentration of residues acceptable by baby food producer in any raw material to be processed. The only residues exceeding this concentration were captan and teflubenzuron. Based on these data farmers may consider the choice of pesticides for optimisation of treatment plants enabling production of safe crop suitable for baby food production.
