Physan 20™

$6.50
Phyan 20™  disinfectant gives greenhouse and nursery growers a biodegradable, cost-effective way to control unwanted plant pathogens and algae on hard surfaces, such as floors, benches and walls.

Unlike bleach, Physan 20™ is EPA-registered for broad-spectrum control of pathogens and algae in and around greenhouses and causes no damage to clothing from splashes. Physan 20™ lasts four times longer in solution than bleach and provides residual control as long as treated surfaces stay wet, without bleach’s odor, irritation and volatility. 

Physan 20™ is labeled for use in greenhouses, nurseries, landscapes and interiorscapes on work areas, benches, tools, containers, walkways, floors, evaporative cooling pads and plants.

Physan 20™ poses no human or environmental risk when it is used at recommended levels and according to label instructions. 

Physan 20™ controls disease spreading organisms which can be carried from plant to plant by using contaminated pots, flats, seed beds, tools and human hands. 

Warning: Toxic to fish. 

Always read and follow label directions.
