The objective of this research was to compare the use of single and mixed plant cultivation to remediate endosulfan sulfate-contaminated soil. The plants chosen for the study came from three different families: sweet corn from Poaceae, cowpea from Leguminosae, and cucumber from Cocurbitaceae. Members of the poaceae and Leguminosae families have been used to remediate soil sites contaminated with hydrocarbons, PAHs, PCB, and lindane. The main benefits of using these plants for phytoremediation include their fibrous root system, having large root surface area, excretion of laege amount of root exudate, and/or having the ability to fix nitrogen. Also, pants from the Cucurbitaceae family have been reported to bioaccumulate organochlorine insecticides such as heptachlor and DDT from soil.
