Abstract

Tomato is a very common agricultural commodity in our country and The producers use pesticides frequentely for its pest control. This vegetable is usually presented to market a short time after the last insecticide spraying, it is more probable to be contaminated in the time of consumption. This study was conducted to measure the safety interval of the two common insecticides used in greenhouses of Iran, Chlorpyrifos and deltamethrin. Tomato samples cultivated in 2 greenhouses with the design pattern of randomized complete block with 3 replicates. For deltametherin within one hour and 1, 2, 3, 4, 5, 7, 10, 15 days after spraying and for Chlorpyrifos within one hour and 1, 3, 5, 7, 10, 15, 20, 30 days after spraying sampling was performed. Samples in laboratory were extracted by using SPE (Solid Phase Extraction) and with the help of Nitrogen were concentrated and extracts were injected for measurement into HPLC (High Performance Liquid Chromatograph), GC (Gas Chromatograph), GC/MS (GC/Mass Spectrometer) devices. Data were compared with WHO/FAO and Recovery results were 101% and 94% for Chlorpyrifos and deltametherin as respectively also results showed that deltametherin has the php about 3 days and Chlorpyrifos has the php near 15 days in greenhouse condition has been studied. However, to get the POST HARVEST PERIOD under farm condition more studies are needed.
