Mechanism of Ozone and Ozonated Water in Replacing Pesticides to Control Plant Diseases and Pests: Leveraging ozone's powerful oxidizing properties, it can oxidize and decompose bacterial enzymes such as glucose oxidase and cysteine oxidase. Moreover, ozone disrupts the redox processes involved in bacterial metabolism, thereby inhibiting bacterial growth and reproduction and ultimately leading to bacterial death. Unlike higher animals, plant insects do not rely on blood circulation to deliver oxygen throughout their bodies; instead, their respiratory systems—comprising spiracles and tracheoles—directly facilitate gas exchange between internal tissues and the external environment. Based on this unique physiological feature, ozone exerts its toxicological effects by oxidizing and inhibiting various enzymes within insect bodies, disrupting their respiratory and metabolic processes and causing them to suffocate and die. Meanwhile, ozonated water effectively eliminates fungal pathogens and viruses from plant leaf surfaces, creating a pollution-free ecological environment for plants and enabling them to thrive vigorously.
With the development of agricultural production and advances in science and technology, pesticides are playing an increasingly significant role in protecting crops, controlling pests and diseases, improving the human living environment, and combating diseases. Due to the extensive use of pesticides, pesticide residues are inevitably present in agricultural products—among which pesticide residues in fruits and vegetables have drawn particular attention, as they are closely linked to people's daily lives and health. This poses a serious threat to both public health and personal safety. Theoretically, ozone is a highly effective oxidizing agent that can oxidize most elements and compounds to their highest oxidation states. It exerts a powerful oxidative decomposition effect on organic substances without generating secondary pollutants and is harmless to humans. Moreover, most pesticides contain chlorine or phosphorus; when they react with ozone, they produce oxides of sulfur, phosphorus, carbon, and water, or corresponding acids and water, thereby breaking down into small, non-toxic, and harmless molecules. Ozone water can also degrade pesticides, and the key to effective pesticide degradation lies in the proper concentration of ozone or ozonated water. Experimental evidence has shown that the concentration of ozonated water must exceed 2 mg/L to be effective. Currently, very few companies in the same industry possess ozone equipment and technologies capable of directly producing ozonated water at such high concentrations. However, our factory’s equipment can generate ozonated water with concentrations as high as 9 mg/L, and the cost for producing one ton of high-concentration ozonated water remains remarkably low. Our factory has already obtained the Hygiene License for Disinfection Equipment issued by the Ministry of Health and the Medical Device Approval Certificate (Class I) issued by the Jinhua Municipal Administration for Drug and Medical Device Supervision. In particular, our products have been tested by the Zhejiang Provincial Center for Disease Control and Prevention and the Hubei Provincial Institute for Supervision and Inspection of Electronic Information Products, and the test results have been nothing short of astonishing.
Earlier this year, our factory conducted a joint trial with the Jinhua City Agricultural Science and Technology Research Institute. We used high-concentration ozone water to treat strawberries grown in soilless cultivation greenhouses. During the trial, crops showed significantly better growth and lower incidence of disease—even though no pesticides were used at all—compared to plants treated with chemical pesticides for disease control.
