The United States Department of Agriculture (USDA) has released a set of regulations that govern the use of ozone in crop production. The guidelines, which were drawn up in consultation with the Environmental Protection Agency (EPA), establish maximum allowable concentrations of ozone for different types of crops and outlines steps that farmers must take to ensure that their crops are not harmed by the gas.  

U.S. Department of Agriculture (USDA)

The U.S. Department of Agriculture (USDA) is a Cabinet-level agency that oversees the nation’s agricultural, forestry, and food programs. The USDA’s mission is to “provide leadership on food, agriculture, natural resources, and related issues based on sound public policy, the best available science, and efficient management.” The USDA operates more than 100 research laboratories and employs over 2,500 scientists. In addition, the USDA provides agricultural assistance to farmers and ranchers through programs like the Supplemental Nutrition Assistance Program (SNAP) and the Conservation Reserve Program (CRP). The USDA also works to promote international agricultural development and trade through its Foreign Agricultural Service (FAS).

Ozone Generator for Crop Production

Ozone generators are devices that create ozone gas. They are often used to treat indoor air quality problems. However, ozone generators should not be used in occupied spaces, as they can pose a health risk. Ozone generators are also used in crop production. Ozone has been shown to improve plant growth and yields, and it can help to control pests and diseases. When used properly, ozone generators can be a valuable tool for farmers and gardeners alike.

USDA Regulations on Using Ozone for Crop Production

Ozone can be beneficial for plants, and is regulated as a manufactured substance. The only exception to this rule are ozonation systems, which are allowed to be cleaned with ozone. If you use ozonated irrigation water on your crops, they will 100% organic certified. Synthetic materials may be used in organic crop cultivation according to the U.S. Department of Agriculture’s Code of Federal Regulations 205.601 section on synthetic substances. These chemicals should not pollute crops, soil, or water and must meet all other limitations set forth in this CFR section.

The National Organic Program


The National Organic Program (NOP) was established by the USDA to confirm that organic foods are, in fact, organic. The NOP does this by Creating rules and guidelines Covering all aspects of food production from processing to sale Administrating and enforcing the regulatory framework for national organic standards.

Organic foods come in three degrees of quality:

  • 100% Organic — Products made entirely with certified organic ingredients and methods
  • Organic — Products with at least 95% organic ingredients
  • Made with Organic Ingredients — Products containing a minimum of 70% organic ingredients

The only foods that are permitted to show the USDA Organic label on packaging to consumers are those categorized as 100% organic or 95% organic. There are numerous rules and regulations that affect what chemicals may be used in organic food items. In certain cases, ozone can be utilized, but not all of them.

Bottom Line

The USDA has regulations on the use of ozone in crop production. Despite the benefits of ozone, there are still some risks associated with its use which must be considered. Overall, ozone appears to be a safe and effective tool for growers when used within the guidelines established by the USDA.
