Residue dynamics of cyprodinil and fludioxonil in pollen and nectar of courgette (Cucurbita pepo L.)

The aim of this study was to investigate and compare the residue profile in pollen, nectar, flowers, anthers, and leaves of courgette plants following a foliar spray application of two pesticides with contact and systemic properties. Therefore, glasshouse experiments were set up. Courgette plants were sprayed during flowering with cyprodinil and fludioxonil. Samples were taken daily over the course of two weeks and were analysed for residues of both active ingredients using LC-MS/MS.
