What is Priority?
Priority is a biological insecticide based on a selective strain of naturally-occurring entomopathogenic fungus, Paecilomyces fumosoroseus. The product contains spores and mycelial fragments of P. fumosoroseus. It is available in liquid (1x109 CFU's/ml) and powder (1x108 CFU's/gm) formulation.
Mode of Action
When the spores of this fungus come in contact with the cuticle (skin) of the pest such as mites and insect, they germinate and grow directly through the spiracle in the cuticle in to the inner body of their host. The fungus proliferates throughout the insect's body, draining the mite and insect of the nutrients and the infected mite and insect eventually dies.
Paecilomyces fumosoroseus infects the mites and insects upon contact and does not need to be consumed by the host to cause infection.
