Abstract

The 14C-labelled PIRIMIPHOS-METHYL with specific activity of 53.39µ Ci/mg in combination with Non-labelled and pure PIRIMIPHOS-METHYL were used on STORED WHEAT with the concentration of 8.88 mg/kg. After treatment, the grains were stored in glass-containers with tight caps for 380 days at 5-30 C in such a climate as Karaj. Surface and extractable penetrated residues were measured at specific times [3]. The14C-labelled PIRIMIPHOS-METHYL residue in stored-wheat reached to %82.02 of the applied dose after 380 days. During this period the SURFACE RESIDUE decreased from %63 to %33, but the EXTRACTABLE RESIDUE increased from %32 to %49. This experiment shows that PIRIMIPHOS-METHYL residue penetrates from the surface to the body of the grain as time goes by. It was also indicated that PIRIMIPHOS-METHYL is rather persistant. Due to the fact that the maximum residue limit in stored grains is 10 mg/kg [8], therefore , higher dose application above this limit may leave non-tolerable residue amount in stored-wheat.
