Endosulfan sulfan was removed to a lesser extent from soil when two different plant species were grown together as compared to single plant cultivation(Table 4). The reason for this is unknow. The greatest extent of endosulfan sulfate removal was found in mixed cropping of sweet corn and cowpea. On day 60 the percentages of endosulfan sulfate remaining in the rhizospheric soil of sweet corn, cowpea. and their bulk soil were, respectively(Table 4). Good เอนโดซัลแฟนซัลเฟต removal(about 50.6%) was also seen on day 60 in the rhizosphere of cowpea when this plant was together with cucumber. As with single plant cultivation, greater amount of endosulfan sulfate was removed in the rhizospheric soil than bulk in mixed plant pots. On day 60, the highest removal of endosulfan sulfate from the bulk soil was seen in pots containing sweet corn and cowpea (44% removal), followed by sweet corn and cumber (36.8% removal), and then cucumber and cowpea(20%)(Table4).
