title: A case study on toxicological aspects of the pest and disease control in the production of the high-quality raspberry (Rubus idaeus L.).
abstract: The field studies on the residue levels of the fungicides and insecticides used in commercial raspberry (Rubus idaeus L.) plantation have been performed. Starting on the first day of harvesting (on June 19), 20 laboratory samples of fruit, 10 laboratory samples of leaves and 4 samples of soil were analyzed and the residue levels were compared to the Maximum Residue Limits (MRL) and Acceptable Daily Intakes (ADI). All analyses were carried out using extraction method and gas chromatography technique. Esfenwalerate (Sumi-alpha 050 EC) and beta-cyfluthrin (Bulldock 025 EC), the insecticides belonging to the group of synthetic pyrethroids, were not found in harvested ripe fruits, while cypermethrin residues (Cyperkill 25 EC) applied on May 24, 25 days later was still found on low levels in fruits (0.026 mg kg(-1)) and in leaves (2.58 mg kg(-1)). In turn, residues of chlorpyrifos (Dursban 480 EC), applied to the soil on May 15 against the cockchafers Melolontha melolontha and Otiorhynchus sp., were found at the level 0.004 mg kg(-1). The content of pesticides in ripe fruits depended mainly on the dose and on the time that has elapsed from the date of their application and were as follows: boscalid -0.950, pyrimethanil -0.917, pyraclostrobin -0.253 cypermethrin -0.026 and chlorpyrifos -0.004 mg kg(-1) while in leaves: boscalid -30.64, pyrimethanil -8.13, pyraclostrobin -15.82, cypermethrin -2.58 and chlorpyrifos -0.15 mg kg(-1). The highest average daily intake was in the case of boscalid, and in fruits and leaves reached the levels 0.205 and 6.63, in total 0.33% and 12.18% of ADI, respectively.
