Metarhizium Anisopliae Powder (CAS 67891-79-6) is an entomopathogenic fungus utilized as a potent biological control agent in agricultural pest management systems. Biologically identified as the Green muscardine fungus, this spore-based powder functions by adhering to the insect cuticle and penetrating the host to cause mortality through mycosis. As a specialized Bio-insecticide fungal spore preparation, it is applied in integrated pest management (IPM) strategies to control termites, locusts, and beetle larvae without relying on synthetic chemical residues. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific colony-forming unit (CFU) counts. Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

Product Description
Metarhizium Anisopliae is a naturally occurring fungus that acts as a potent parasitoid against various insect pests. The powder consists of dormant spores (conidia) mixed with an inert carrier.
Mechanism of Action: When the spores come into contact with the insect’s cuticle (skin), they adhere and germinate. The fungus then penetrates the insect’s body, releasing enzymes and toxins (destruxins) that disrupt the insect’s internal systems. The insect typically dies within 3 to 7 days, and the fungus may sporulate on the cadaver, creating a “green fuzz” that can infect secondary targets.
It is highly effective against pests that have developed resistance to chemical insecticides and leaves no toxic residue on crops.

Applications
- Target Pests:
- Soil Pests: Termites, Grubs, Wireworms, Root Weevils.
- Foliar Pests: Locusts, Grasshoppers, Aphids, Thrips, Cockroaches, Spittlebugs, and Beetles (Coleoptera).
- Crop Usage:
- Suitable for vegetables, fruits, tea plantations, forests, turf, and field crops (rice, corn, sugarcane).
- Application Methods:
- Foliar Spray: Mix with water and spray during early morning or late afternoon (avoid high UV). Recommended dosage varies by pest load (typically 1-2 kg/hectare).
- Soil Drench/Treatment: Apply around the root zone to control larvae.
- Termite Control: Applied directly to termite mounds or tracks.
Storage Conditions
- Temperature Sensitivity: This product contains living spores. High temperatures will deactivate the fungus.
- Short Term: Store in a cool, dry place below 25°C.
- Long Term: Refrigeration (4°C – 10°C) is highly recommended to extend shelf life beyond 12 months.
- Moisture: Keep packaging tightly sealed. Moisture can cause premature germination.
- Light: Protect from direct sunlight (UV radiation kills spores).
Safety Precautions
- Compatibility: NEVER mix with chemical fungicides. Fungicides will kill the Metarhizium spores. It can be mixed with most insecticides and fertilizers.
- Inhalation: Avoid breathing the dust/mist. Spores may cause respiratory sensitization in some individuals. Wear a standard dust mask during application.
- Re-entry Interval: Generally safe for re-entry as soon as the spray dries, but follow local regulations.
- Non-Target Organisms: Safe for birds, fish, and bees.
FAQ - Technical & Supply Chain

Q:
What is Metarhizium Anisopliae Powder CAS 67891-79-6?
A: Metarhizium Anisopliae Powder CAS 67891-79-6 is a wettable-powder biological insecticide made from dormant conidia of the entomopathogenic fungus Metarhizium anisopliae, also known as the green muscardine fungus. It is used for control of soil and foliar insect pests. -
Q:
How does Metarhizium Anisopliae Powder kill insects?
A: The spores adhere to the insect cuticle, germinate and penetrate into the body. The fungus then grows inside the insect and releases enzymes and destruxins, usually killing the pest within 3 to 7 days. -
Q:
Which pests can this biological insecticide control?
A: It targets soil pests such as termites, grubs, wireworms and root weevils, and foliar pests such as locusts, grasshoppers, aphids, thrips, cockroaches, spittlebugs and beetles. It is especially useful in integrated pest management for pests resistant to chemical insecticides. -
Q:
What spore count and quality specifications does this powder provide?
A: The standard export grade provides at least 10 billion CFU per gram and can be supplied up to about 40 billion CFU per gram. It also specifies at least 90% spore germination, no more than 8.0% moisture, at least 80% suspensibility and no more than 2.0% contamination. -
Q:
How is Metarhizium Anisopliae Powder applied?
A: For foliar pests, mix the wettable powder with water and spray in the early morning or late afternoon, typically at 1-2 kg per hectare. For soil pests, apply as a drench around the root zone, and for termites apply directly to mounds or tracks. -
Q:
Can it be mixed with chemical fungicides?
A: No. Chemical fungicides can kill Metarhizium anisopliae spores, so they must not be mixed or applied at the same time. The powder can generally be used with most compatible insecticides and fertilizers. -
Q:
What storage conditions keep the spores viable?
A: Store in a cool, dry place below 25 C for short-term use. For long-term storage, refrigerate at 4-10 C and keep the packaging tightly sealed, because heat, moisture and direct sunlight can reduce spore viability. -
Q:
Is Metarhizium Anisopliae Powder safe for non-target organisms?
A: It is considered safe for birds, fish and bees when used as directed. During mixing and application, avoid breathing the dust or mist and wear a standard dust mask because spores may cause respiratory sensitization.
