Solomon Insecticide: Beta-Cyfluthrin + Imidacloprid Use

Solomon is a combination insecticide developed by Bayer, formulated as Beta-cyfluthrin 8.49% + Imidacloprid 19.81% w/w OD (oil dispersion). The formulation combines a fast-acting synthetic pyrethroid with a systemic neonicotinoid to provide dual knockdown and residual control against mixed infestations of chewing and sucking pests. Indian growers apply Solomon across cotton, soybean, brinjal, and vegetables to control bollworms, semiloopers, aphids, jassids, and whiteflies.

Dual chemistry and oil dispersion (OD) formulation

Solomon pairs two distinct neurotoxic modes of action formulated in an advanced oil-based delivery system.

  • Beta-cyfluthrin (pyrethroid, IRAC Group 3A): Modulates sodium channels, delivering immediate contact knockdown of chewing caterpillars.
  • Imidacloprid (neonicotinoid, IRAC Group 4A): Disrupts nicotinic acetylcholine receptors, providing systemic control of sap-sucking pests.
  • Oil Dispersion (OD) technology: Enhances droplet adhesion and spreading on waxy leaf surfaces, providing notable rainfastness.
  • Broad-spectrum synergy: Clears complex simultaneous infestations of caterpillars and sucking insect vectors in a single spray.

Target crops and major pest complexes

Solomon is registered under CIBRC regulations for high-pressure multi-pest attacks in field and vegetable crops.

  • Cotton: Simultaneous control of aphids, jassids, thrips, and American bollworm.
  • Soybean: Control of girdle beetle, semilooper caterpillars, and stem fly.
  • Brinjal (Eggplant): Dual management of fruit and shoot borer alongside jassids and whiteflies.
  • Vegetables: Broad control of leaf-feeding caterpillars and disease-carrying sucking insect vectors.

Spraying guidelines, dosage, and safety protocols

Apply Solomon when scouting reveals both caterpillar and sucking pest build-up. Use hollow cone nozzles for thorough canopy penetration. Ensure containers are shaken thoroughly before measuring to disperse the oil carrier. Operators must wear full personal protective clothing, rubber gloves, and protective goggles. Observe statutory pre-harvest intervals before harvest.

Common questions

What are the active ingredients in Solomon insecticide?

Solomon contains Beta-cyfluthrin 8.49% and Imidacloprid 19.81% w/w in an oil dispersion (OD) formulation.

What is the advantage of the Oil Dispersion (OD) formulation?

The oil carrier allows spray droplets to stick tightly to waxy leaf surfaces, reducing runoff and improving rainfastness.

Can Solomon be used for simultaneous control of caterpillars and sucking pests?

Yes, its dual formulation controls chewing caterpillars through Beta-cyfluthrin and sap-sucking pests through Imidacloprid.
