Abstract

Considering the importance of agricultural raw materials, especially tomatoes, which are considered as one of the main products of Iranian household basket and commonly used freshly, it is important to pay attention to the amount of pesticide residues in agricultural raw materials.
 In greenhouse for the control of pests, diazinon (60% EC), imidacloprid (35% SC), primicarb (50% WP) and acetamiprid (20% SP) are used. The aim of the present study was to assess the residual contents of four pesticides: diazinon, imidacloprid, primicarb and acetamiprid in greenhouse tomato  (Solanum lycopersicum  ) var.Izmir .
The pesticides were applied on the above yields in a setting stage. Samples were taken daily, acetonitrile extracted, cleaned up using a silica gel column and residual contents of diazinon, imidacloprid, primicarb and acetamiprid were analyzed using a Liquid chromatography it an DAD detector (HPLC-DAD).
The present results indicated that: imidacloprid and pirimicarb were found to be more persistent in greenhouse tomato  (Solanum lycopersicum  ) var.Izmir compared to other two tested pesticides; data also reported that the lowest residue level of <0.05 mg.kg-1 in in (Solanum lycopersicum  ) var.Izmir was detected Investigation of the concentration of fluids two days after spraying showed the highest residue of primicarb pesticide at 10.90 mg / kg and then the acetamidprid dose of 9.6 mg / kg which after 5 to 7 days Less than half reduced, while the lowest remaining in the two premicarb and diazinon after 10 days is 0.81 and 0.09 mg / kg, respectively. According to the results of the research. Which indicates that compliance with the PHI (Per Harvest Interval) reduce the risks of residual pesticides
