Insect Killer Beauveria Bassiana, natural fungus, 20g

Beauveria bassiana is a non-specific entomopathogen — a parasitic fungus that infects agricultural pest insects and is used to control their populations as a biopesticide.

Spores land on the pest's body surface and germinate into its internal tissues, forming mycelium. Hyphae gradually penetrate the hemolymph, where the fungus actively reproduces and spreads throughout the insect's body. The pathogen consumes nutrients dissolved in the hemolymph and produces toxins. As a result, the host insect dies from exhaustion and intoxication. The mycelium develops and emerges through the integument onto the body surface. Here, spores are formed, which are responsible for infecting the next generation of insects.

Infection occurs in several ways — through direct contact between infected and uninfected individuals, via insect vectors, or through airborne droplets. For example, Beauveria bassiana is effective in killing bed bugs exposed to cotton fabric treated with fungal spores, as infected bugs carry the fungus back to their hiding places.

Beauveria bassiana parasitizes a very wide range of arthropods:

• Thrips
• Aphids (melon aphid, pea aphid, cabbage aphid)
• Mites (spider mite)
• Flies and mosquitoes (whiteflies, stem borers, fungus gnats, shore flies)
• Moths (cabbage moth, potato tuber moth, onion moth, beet leaf miner)
• Beetles (Colorado potato beetle, rape blossom beetle, bark beetle, black vine weevil, cotton boll weevil, cereal leaf beetle, coffee berry borer, emerald ash borer, Japanese beetle, Mexican bean beetle, red palm weevil, strawberry root weevil, etc.)
• Caterpillars and butterflies (bean pod borer, cabbage armyworm, cotton bollworm, meadow moth, European corn borer, Douglas-fir tussock moth, invasive gypsy moths, codling moth, apple clearwing moth, etc.)
• True bugs (shield bug, lygus bugs, brown marmorated stink bug)
• Fire ants
• Others (flea beetles: wavy, turnip, cereal stem, black flea beetle; grape berry moth, rose tortrix, Italian locust, migratory locust, grasshoppers, mealybugs, termites)

Dosage: 2 grams per 1 liter

Spray Beauveria bassiana spores onto affected plants — apply a solution of the powder in water. One package is enough for 10 liters of water.

Safety and Impact on Living Organisms

Beauveria bassiana does not infect plants. Its targets are exclusively insects and other arthropods (mites). It specializes in overcoming their chitinous exoskeleton.

• Weakened or damaged plants: If there are fresh wounds (mechanical damage, cuts) on a stem or leaf, spores can theoretically begin to develop in these dead or weakened tissues as a saprophyte (feeding on organic matter). However, this is not a typical infection, and the fungus will not spread to healthy parts of the plant.
• Very high humidity: Under conditions of excessive and constant moisture (which is harmful in itself), a saprophytic mycelial film may develop on the plant surface, which can mechanically impede gas exchange, but again, this is not an infection.
• Allergenic dust: In very rare cases during industrial production, spores can cause respiratory allergic reactions in humans, but not in plants.
