Abstract: As people's attention to the safety of agricultural products has gradually increased, pesticide residues have always been a problem to be solved urgently. Various pesticide residues in fruits and vegetables endanger the health of consumers. The existing pesticide residue reduction technologies are mainly divided into electrolytic water technology, ultrasonic technology, and ozone degradation technology. These technologies are gradually being applied to a large number of fruit and vegetable washing machine products. Different pesticide residue reduction technologies have different mechanisms and methods for pesticides. Analyze the principles and market applications of pesticide residue reduction technologies.

Key words: Reduce pesticide residues, Electrolyzed water, Ultrasound, Ozone
