Dynamics of chlorpyrifos residues in cauliflower cultivation fade

摘要

Studies on the decay of chloropyrifos residue (Dursban 480 EC) in cauliflower were carried out in 2011. Two variants of spraying treatment were tested - the preparation was applied once and twice to cauliflower plants under the field conditions. A total of 50 samples of leaves and mature roses were analysed. The level of chloropyrifos residues detected in the plant material ranged from 0.01 to 0.006 mg/kg (after one treatment) and 0.005 mg/kg (after two treatments). In general, the level of detectedresidues of the preparation did not exceed 0.01 mg/kg.
