Description: PFR-97 microbial insecticide contains a naturally occurring fungus that controls some of agriculture’s most devastating pests, including whitefly, aphid, thrips and spider mite.

Mode of Action: Paecilomyces fumosoroseus, the active ingredient in PFR-97, is a naturally occurring fungus that infects several insect pests, including whitefly, aphid, thrips and spider mites. Under proper environmental conditions, spores of the fungus attach to and penetrate the cuticle of the insect pest. The fungus grows inside the insect causing its death. The fungus then emerges from the dead insect to release more spores to infect other insects.

Monitoring of pest pressure is critical to the effective use of PFR-97™. Efficacy results from germination and growth of the beneficial fungus over several days, so applications should start before pest numbers have reached crisis levels. PFR-97™ is most effective when application is initiated just before or at the first signs that target pests are present. Optimal Environmental Conditions: PFR-97™ is most effective when relative humidity is 80% or higher for 8-10 hours. Irrigating will increase humidity levels. Application at times of low air movement and moderate temperature (70-90°F) will reduce drying conditions and maintain the effectiveness of the fungus.

Compatibility: PFR-97™ can be used in conjunction with most other pesticides and is compatible with beneficial arthropods. It can be mixed with copper-based fungicides without impacting performance. However, do not mix with other fungicides, or apply within 5 days of fungicide applications other than copper. PFR-97™ can be mixed with most insecticides for which such mixing is permitted by the label, in accordance with the most restrictive label limitations and precautions of all products used in the mixture. Do not exceed any label dosage rates. However, physical compatibility should be checked by mixing small quantities of each tank mix partner in correct proportions (“jar test”) prior to the first time such a mixture is attempted.
