PFR-97 uses Isaria fumosorosea Apopka Strain 97 to infect and kill target pest insects and mites including aphids, whiteflies, thrips and various mite species. This naturally occurring, entomopathogenic fungus continues to grow and spread once applied to offer maximum protection against plant feeding pests above and below ground. As the infection moves through the pest population, the fungus continuously propagates in the dead and dying pests. Once it kills the pest, spores erupt from the pest ready to infect the nearest suitable host.
