Chemical Product Description & Applications

Metarhizium anisopliae is an entomopathogenic fungus used in biological insect-management products. Viable conidia attach to susceptible insects, germinate and penetrate the cuticle, allowing infection to develop. This contact-based biological pathway differs from ingestion-dependent insecticides and can support management of suitable soil-dwelling or exposed insect stages.

The selected product form is a wettable conidial powder for agricultural formulation or application systems. Its biological activity depends on strain identity and viable propagules, not simply the mass of fungal powder. Moisture, temperature and contact with the target influence infection, and mortality develops through a biological process rather than immediate knockdown. The strain and finished product define the actual target spectrum.

Typical Applications

  • Soil-insect management: Used in suitable root-zone or soil treatment programs targeting susceptible insect stages identified for the selected strain and product.
  • Foliar insect-management programs: Used in appropriate spray formulations where viable conidia can contact susceptible pests under conditions that support infection.
