Objective of this study is to determine methamidophos and methyl-parathion residues in 5 favourite vegetables, convolvulus, cowpea, collard, white lettuce and cabbage. We collected vegetable samples from Banglumpu market, Khon Kaen Province. Six samples were collected for each plant and all together were 30, 10 (33.33 percent) samples were found pesticide residues. No residue was found in Convolvulus, while cowpea was found methamidophos residue in 1 (16.67 percent) sample. Methamidophos was found in Collard in 3 (50 percent) samples, in White lettuce 2 (33.33 percent) samples, in cabbage 2 (33.33 percent) samples. Cabbage was also found methamidophos and methyl-parathion residue in 2 (33.33 percent) samples (one sample had methyl-parathion over MRL). This study illustrates that hazard pesticides are still used in consumed vegetables. Cabbage was found both amount and type of pesticide residue over than others.
