Major classes of approved organic insecticides
Organic pest management relies on diverse biological and botanical modes of action.
Primary categories include:
- Botanical extracts: Formulations based on Azadirachtin (neem oil and neem seed kernel extract / NSKE), Karanj oil (Pongamia), and garlic-chilli decoctions that act as antifeedants and insect growth disruptors.
- Entomopathogenic fungi: Beneficial fungi including Beauveria bassiana, Metarhizium anisopliae, and Verticillium lecanii that parasitize and kill caterpillars, whiteflies, and root grubs.
- Microbial insecticides: Formulations based on Bacillus thuringiensis (Bt), which produce crystal endotoxins that selectively destroy caterpillar gut linings.
- Traditional on-farm preparations: Bio-fermented formulations such as Dashparni Ark, Agniastra, and Brahmastra prepared from cow urine, neem leaves, and medicinal herbs.
Target insect pests and integrated crop management
Organic insecticides effectively manage a broad spectrum of destructive pests:
Pest spectrum and biological solutions:
- Sucking pests (Aphids, whiteflies, thrips): Controlled using neem oil (1500 to 10,000 ppm Azadirachtin) or Verticillium lecanii sprays.
- Lepidopteran caterpillars (Bollworms, semiloopers, armyworms): Controlled using Bacillus thuringiensis (Bt) or Beauveria bassiana.
- Soil-dwelling grubs and termites: Suppressed using Metarhizium anisopliae incorporated with farmyard manure into moist soil.
- Predator conservation: Because bio-insecticides have narrow target specificity, natural predators like ladybird beetles and lacewings thrive in the ecosystem.
Spraying best practices and quality certification
Apply entomopathogenic fungi during late afternoon hours when UV radiation is low and relative humidity is high to promote fungal spore germination. Ensure bio-insecticides carry valid CIBRC registration numbers and certification from accredited organic agencies under NPOP. Store biological products in cool, shaded spaces to preserve viable spore counts.

Common questions
What are organic insecticides?
They are natural, botanical, or biological pest-control products certified under NPOP standards that manage insect pests without synthetic chemicals.
How does neem-based Azadirachtin control insect pests?
Azadirachtin acts as a powerful antifeedant, repellent, and insect growth regulator that disrupts pest molting and egg-laying.
Why should entomopathogenic fungal sprays like Beauveria bassiana be applied in the evening?
Fungal spores are sensitive to solar ultraviolet (UV) radiation and require overnight humidity to germinate and infect target insects.
