The procedure of Ambrus et al. for extraction and clean up was modified to apply specifically to the extraction of monocrotophos in rice plant for determination by gas chromatography using flame photometric detector. An effective clean up system was developed to remove unwanted substances as well as to separate monocrotophos from other organic phosphate pesticides that interfere in the determination. The extraction utilized acetone/methylene chloride with recovery ranging from 41-53% for standards, while clean up recovery averaged 94% for standards or an overall percentage recovery of 41-55%.
