Abstract

In order to determine the level of residual Dichlorvos pesticide on strawberry fruits in research greenhouse conditions in crop year of 2011-2012, a study was carried out in Education and Research Center for Greenhouse Productions of Islamic Azad University of Khorasgan of Isfahan. Factorial experiment was carried out based on a completely randomized design with two factors of pesticide consumption and different harvesting hours after spraying with 2 and 5 levels with 3 replications. In order to determine the amount of pesticide residues, GC-ECD device was used. The results showed that between the two pesticide usage levels (twice the recommended dose and the recommended dose), there was no statistically significant difference at the 5% level. However, among the hours after harvest, some differences were observed between the two doses, so between 1 hour after spraying and 7 days after spraying, the residual amount was different. At the end it was found that at the recommended dose and double recommended dose treatments in 7 days after spraying with pesticide, the amount of residues of Dichlorvos reached to allow limit of this pesticide residue (0.10) for export to the Europe Union countries.
