In years 2008 - 2010, fungicide preparations Syllit 65 WP, Delan 700 WDG, Thiram Granuflo and Zato 50 WG were applied on apple cultivars Melrose, Golden Delicious and Idared. Surfactants Agrovital, Break-Thru S 240, Silwet L-77 and foliar fertiliser Campofort Garant Ca were added to these fungicides. Fungicides and mixture of fungicides with surfactants (or fertiliser) were applied with Tifone Vanguard sprayer (in 400 l water per ha). Samples of apple fruits were taken after preharvest interval and analyses of amount of pesticide residues were performed. Following analyses were performed after 5-6 month of storage. The maximum residue limit set for tested active ingredients was not exceeded in any sample. However, the amount of pesticide residues stayed above the limit 0.01 mg/kg set for baby food. Although degradation of pesticides by addition of surfactant was delayed only in several cases, the use of surfactants cannot be recommended for late preharvest treatments.
