Ozone generators and other ozone equipment produce ozone with strong oxidizing power and bactericidal effects. Today, it is widely used in agriculture as a useful method for preventing drug damage and environmental purification. Ozone generators can effectively prevent and control downy and gray mold on tomatoes, cantaloupes, and cucumbers in greenhouses, as well as remove mold and aphids from eggplants, mushrooms, potted plants, and other plants. They also promote development. A small greenhouse can achieve good dispersion results by installing one unit and laying pipes above the pathway.
