In an experiment the effective dose and the time of application of phenamiphos (Nemacur 10G) for control of the root knot nematode, Meloidogyne javanica, infecting cucumber, was found out to be 22.5 g/m2 of commercial product and the best time of its application was one week prior to sowing of seeds. However, the results revealed that in concomitant and sequential (one week before) treatment, highest yield were obtained. For the determination of Nemacur residue of the most effective dose of 22.5 gr/m2 the products of the treatment blocks were harvested for six times. The samples were transferred to the laboratory and then prepared for extraction, purification and finally measurement of the residues by GC-NPD. The results were compared with the Codex Alimentarius MRL for Nemacur on a vegetable which is 0.5 ppm and the best timing for pesticide application which was estimated to be one week before sowing of seeds was chosen. It is therefore suggested that the cucumbers produced up to 4th stage of harvesting be used by the consumers, because the products harvested up to this stage possess residues which are closed to the MRL shown by codex Alimentarius.
