Zinc sulfate is a naturally occurring pesticide and can be found in plants, soil, food, and water. It is a combination of sulfur and zinc. Zinc is an essential nutrient for humans, animals, and plants. Organisms need zinc for their normal function and adjust their internal environment to keep zinc levels steady. Too much zinc sulfate can damage the skin, affect the stomach and intestines, and irritate the respiratory tract. Freshwater fish and invertebrates are very sensitive to zinc. Zinc sulfate is an herbicide typically used for moss control.
