Mode of Action: Isaria fumosorosea, the active component in PFR-97 20% WDG, is an entomopathogenic fungus found in infected and dead insects as well as in some soils. Isaria fumosorosea infects many insect and mite pests that occur on foliage and other above-ground plants, as well as many soil-dwelling pests. Under proper environmental conditions, spores of the fungus attach to and penetrate the cuticle of the target pest. The fungus grows inside the pest causing its death. The fungus then emerges from the dead
pest to release more spores to infect other pests.
Monitoring of pest pressure is critical to the effective use of PFR-97 20% WDG. 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 20% WDG is most effective when application is initiated just before or at the first signs that target pests are present.
[Optimal Environmental Conditions: PFR-97 20% WDG is most effective when relative humidity is 80% or higher for 8-10 hours. [Watering walkways, [and/or] operating sprinklers, misters, or cooling pads] {or} [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 20% WDG can be used in conjunction with most other pesticides and is compatible with beneficial arthropods. It can be mixed with copperbased fungicides without impacting performance. However, do not mix with other fungicides, or apply within 5 days of fungicide applications other than copper. PFR-97 20% WDG 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.
