Abstract
These studies were carried out to determine the residual behaviour of triazophos organophosphorous insecticide on moloukhia leaves and okra fruits. The residue half life values determined on moloukhia and okra were 1.55 and 3.3 days, respectively. The removal effect of some processing steps (including washing, freezing, drying and storage) were also studied. It could be concluded that processing reduce triazophos residue to a safe level for consumption. Another part of this study includes a survey carried out for detecting the contamination of moloukhia and okra with organophosphorous insecticides in samples collected from El-Qalubia, EI-Dakahlia and ElGharbia governorates markets. It was found that all detected organophosphorous residues were below the Maximum Residue Limits (MRLs) of the Codex Committee on Pesticide residues (CCPR), compared with vegetable crops similar to moloukhia and okra.
