Abstract: [Objectives] To fully understand the quality of commercial enzyme inhibition-colorimetric pesticide residue rapid detection kits, so that they can play a greater role in the detection and supervision of agricultural products. [Methods] The sensitivity of 28 kinds of pesticides was determined by using the commercially available enzyme inhibition colorimetric rapid detection kit with Hendu brand. [Results] There was a significant difference in the sensitivity of the kit to each pesticide, and the kit was more sensitive to dichlorvos among the 28 pesticides tested. The sensitivity to methyl isosalifos, dimethoate, isocarbophos, fenthion and phorate was poor, and the sensitivity to quinalphos was different between 3 mL and 2.5 mL. [Conclusions] The large difference of the sensitivity of the enzyme inhibition-colorimetric rapid detection kit for pesticide residues to different kits is a reason for the false positive and false negative test results of the kit, which needs to be paid attention to by relevant personnel.
