What Is Granulovirus Sprays (GV)?

Closely related to NPV viruses but with different inclusion body structure. Each granule contains a single virus particle. Caterpillars ingest granules while feeding, virus replicates in midgut cells, and the insect dies in 5-10 days. Highly species-specific.

Beauveria bassiana

Tier B

Beauveria bassiana is an entomopathogenic fungus that penetrates insect exoskeletons and colonizes the body from within, killing the host in 3-7 days. Most effective in humid conditions like greenhouses, it provides long-term biological suppression of whiteflies and thrips.

Metarhizium anisopliae (Green Muscardine)

Tier B

Metarhizium anisopliae (green muscardine fungus) infects soil-dwelling insects and ticks through cuticle penetration, producing destruxin toxins that kill the host in 5-14 days. Dead insects sporulate green, spreading the fungus to nearby pests.

Kaolin Clay (Surround)

Tier B

Kaolin clay creates a white particle film on plant surfaces that irritates insects, blocks egg-laying, and makes plants unrecognizable to pests. It does not kill — it creates a physical barrier that deters beetles, moths, and aphids before they establish.
