Organic foods are not necessarily pesticide-free. The pesticides that are allowed for organic food production are typically not manmade. They tend to have natural substances like soaps, lime sulfur and hydrogen peroxide as ingredients. Not all natural substances are allowed in organic agriculture; some chemicals like arsenic, strychnine and tobacco dust (nicotine sulfate) are prohibited.
