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% Page 4 of 13 WDG is most effective when application is initiated just before or at the first signs that target pests are present.
