Abstract
This investigation was carried out to study the persistence of pir­imiphos-methyl Insecticide residues on motoukhia, green bean pods and cucumber. Pirimiphos-methyl (actellic) is widely used in Egypt to control economic pests on vegetables. The plan of study included the following: First, determine persistence, half life and sale period for consuming mo­loukhia leaves, green bean pods and cucumber fruits. Second. the effect of washing. blanching. peeling, salting and drying processes in removing insecticide residues from the above mentioned vegetable crop. The re­sults obtained could be summarized as follows: The results indicated that one hour after application the pirimi­phos-methyl residues were 171.0287, 32.5318 and 5.3543 ppm on motoukhia leaves, green bean pods and cucumber fruits, respectively. These amounts decreased to 39.1575, 17.8777 and 1.8849 ppm after one day from application, respectively. Eileen days after treatment the residues became 0.0775. 0.0427. and 0.0172 ppm, respectively. The hall-life values were 11.3. 27.8, 27.8 and 15.9 hours on moloukhia leaves, green bean pods and cucumber fruits, respectively. The evaluation different processes in removing pirimphos-methyl residues from moloukhia leaves, green beans pods and cucumber fruits indicated that washing with tap water removed 53.79% pirimtphos­methyl residues on moloukhia leaves, 38% on cucumber fruits and 13.29% on green bean pods, respectively. Blanching removed 90.24% from residues pirimiphos-methyl on and in moloukhia leaves and 30.84% on green bean pods, respectively. Peeling process of cucumber fruits re­moved 97.35% of pirimiphos-methyl, while salting of cucumber fruits re­moved 97.35% of pirimiphos-methyl, while salting of cucumber fruits re­moved 89.73% after 7 days and drying moloukhia leaves removed 71.19% of pirimiphos-methyl. respectively.
