Recirculating greenhouse irrigation is becoming a more common practice for vegetable growers in the US due to growing concern over freshwater shortages. Utilizing closed loop irrigation systems for greenhouse vegetable production not only saves the grower money due to reduced water and fertilizer use, it also reduces the amount of fertilizers being dispensed into the environment as spent irrigation. One drawback is that water-borne pathogens such as Pythium, Phytophthora, and Fusariam may proliferate in these irrigation systems. To prevent further spread of these pathogens, irrigation is disinfected using chemical sanitizers such as chlorine, chlorine dioxide, ozone, and hydrogen peroxide.
