Limiting the spread of disease-causing pathogens is critical to maintaining healthy plants in greenhouses and horticulture facilities. These pathogens are often harbored and spread through contaminated soil, air, hard surfaces, tools, and water systems. OXINE® and PRO-OXINE® Horticulture contain sodium chlorite that when activated, produces chlorine dioxide. OXINE and PRO-OXINE Horticulture can be used as antimicrobials for water systems to disinfect and control biofilm in irrigation and non-potable water systems for horticultural applications. OXINE and PRO-OXINE Horticulture may also be used as general disinfectants, sanitizers, algaecides, and fungicides for greenhouse and horticulture applications to disinfect hard, non-porous surfaces and to treat and prevent algae, fungus, bacteria, and biofilm.
