Abstract:Apart from being absorbed by the targeted parts of the crops，the remaining pesticides accumulate and permeate into the soil or the air.Therefore，it is particularly important to use reliable，accurate，and effective detection technologies to monitor pesticide residues. This paper reviewed various immunoassay methods for detecting different types of pesticide residues，including enzyme-linked immunosorbent assay（ELISA），fluorescence immunoassay，chemiluminescence immunoassay，immunochromatographic assay，and radioimmunoassay，discussed and compared the basic principles and applications of these techniques，and elaborated on the development potential and trends of different kinds of pesticide immunoassay technologies.
