Physan 20 in the Greenhouse

Efficiently Disinfect your Greenhouse and Control Algae with PHYSAN 20:

Inhibiting the growth of plant pathogens in the greenhouse is a critical component of an integrated pest management (IPM) program.

Regular usage of Physan 20 can control bacteria, viruses, fungi and algae, which if left to establish, can devastate greenhouse crops or provide food for insect pests (algae for fungus gnats). 

PHYSAN 20 as a Disinfectant on Hard Surfaces:

PHYSAN 20 is a liquid concentrate product that mixes with water to create a multipurpose disinfecting solution that can be applied directly on plants and hard surfaces. PHYSAN 20 is labeled by the EPA for use on plants and inanimate hard surfaces to control a wide range of bacteria, fungi, and viruses.

PHYSAN 20 has residual germicidal activity and remains effective for a period of time, particularly on hard surfaces. The solution itself is very stable, remains active and can be used over time. It is particularly useful for: Disinfecting cutting tools - controlling mold and mildew on surfaces such as floors, walls, tabletops and glass - disinfecting work areas and benches - disinfecting pots, flats and flower buckets. 

Dilution rates for these applications are as follows:

PHYSAN 20 as an Algaecide:

Algae is often present in the greenhouses due to the moist and humid environment. Algae growth presents some concerns; growth on floors and walkways are safety hazards and encourages the presence of pests. It can cause unsightly growth on soil surfaces can impede the function of evaporative cooling equipment.

Slime-forming fungus, mold and algae in evaporative coolers can cause odor and accelerate the spread of pathogens throughout the greenhouse. Minimizing the presence of algae has many benefits and should be taken seriously. Physan 20 is safe to use with delicate greenhouse equipment such as mesh filters and fragile evaporative cooling pads. It will not damage metal, plastic, rubber or clothing.

Dilution rates for these applications are as follows:

PHYSAN 20 to Control Algae on Soil Surfaces:

A particular challenge for many growers is preventing and treating algae on the soil surface in the presence of plants. Many algaecides are not labeled for use on plants. However PHYSAN 20 is labeled for this use. It may also be used as a soil drench, will not affect the PH of your soil and has excellent wetting properties.

Dilution rates for these applications are as follows:
