Certis USA PFR-97 10% ES

Certis USA PFR-97 10% ES is an Isaria fumosorosea bioinsecticide designed to help control insect and mite pests on greenhouse, nursery, outdoor, and hydroponic crops. It works by infecting target pests on foliage and other above-ground plant surfaces when used as directed.

PFR-97 10% ES bioinsecticide for greenhouse & hydroponic pest control

PFR-97 10% ES features Isaria fumosorosea, an entomopathogenic fungus that helps manage many common insect and mite pests found on foliage and other above-ground plant parts, and it can also impact certain soil-dwelling pests. The fungal spores attach to the pest, penetrate the outer cuticle, and grow internally—resulting in pest death and continued spread through newly released spores under favorable conditions.

Isaria fumosorosea mode of action that supports IPM programs

Because performance depends on spore germination and growth over several days, monitoring pest pressure and starting applications early—before populations spike—is key for best results. This makes PFR-97 10% ES a strong fit for IPM strategies where consistent scouting and timely applications matter.

Best-use conditions for PFR-97 10% ES on vegetables, fruits & ornamentals

For optimal effectiveness, maintain relative humidity around 80% or higher for 8–10 hours, and aim for moderate temperatures (about 70–90°F) with low air movement to reduce drying on leaf surfaces. It’s labeled for use across many crop types including vegetables, fruits, ornamental plants, tobacco, and other food crops, whether grown outdoors, in greenhouses/other cover, or in hydroponic systems.

Key features:

• Biological mode of action with Isaria fumosorosea to help control insect and mite pests when used as directed

• Fits well into IPM programs alongside scouting and rotation planning

• Effective use across greenhouses, nurseries, outdoor production, and hydroponics

• Can help reduce pest pressure over time as spores spread under favorable conditions

• Clear guidance for results: works best with high humidity (≥80%), moderate temps, and early intervention
