Measurement Residue of Two Current Used Pesticides (Endosulfan and Fosalon) in Colorado Potato Beetle Control

摘要

In our country high amount of insecticides are been consumed to fight agricultural pest that can severely contaminate environment and arable crops. Phosphoric and chlorine toxins, are from important one`s for high toxicity and long-term persistence in the environment, respectively. These toxins directly or indirectly enter environment and enter crops and through it enter nutrition cycle of organisms. Determining of these toxins residue consistency and comparing with world standards will help us in management of correct use of pesticides. In present research effects of different consistency of toxin and crop-dusting time on the rest of two toxins [Endosulfan (Thiodan) and Fosalon (Zolone)] that frequently used in control of Colorado potato beetle were been evaluated. The procedure includes sampling stage, condensation, concentrating and analysis. Analysis was been performed by GC machine and FTD, ECD detectors. According to result, it is specified that using of different consistency with applying of different consistency, residue of these toxins weren`t higher than standard, again it is specified that residue of Fosalon was more than Endosulfan. Results showed that there was no meaningful difference between different consistencies and different using time, from the viewpoint of residue of toxins. Sampling with one month interval showed that with lapse of time toxin`s residue has been reduced as 0.008 PPM.
