Chemical Profile and Systemic Action

Imidacloprid belongs to the chloronicotinyl/neonicotinoid chemical class. It is formulated as a seventy percent water-dispersible granule (WG).

It acts by binding to post-synaptic nicotinic acetylcholine receptors in the insect central nervous system, interfering with nerve impulse transmission and causing paralysis.

Its high water solubility and systemic xylem mobility ensure thorough distribution into new developing shoots and foliage.

  • Formulation: 70 percent Water Dispersible Granules (WG)
  • Systemic xylem movement: Rapidly taken up by seeds, roots, and leaves to protect expanding plant tissues
  • Versatility: Suitable for seed dressing slurries as well as high-volume foliar spray applications

Approved Uses: Seed Dressing and Foliar Application

Imidacloprid 70 WG is registered for protecting crops during critical vulnerable seedling stages and mature growth cycles.

Seed treatment forms a systemic chemical barrier that shields young emerging seedlings from sucking insects for several weeks.

  • Cotton and okra: Seed dressing protects young seedlings against jassids, aphids, and thrips
  • Paddy: Seedling dip or foliar application manages brown planthoppers and green leafhoppers
  • Vegetables and chilies: Controls thrips and whitefly vectors transmitting destructive plant viruses

Dosage Guidelines, Preparation, and Safety

Because of its high 70 percent concentration, accurate measurement following the CIBRC label leaflet is critical to avoid overdosing.

Dissolve the required grams in clean water to create a uniform solution, and avoid spraying during peak honeybee activity.

  • Accurate measurement: Use provided measuring cups or micro-scales to measure exact grams per liter of water
  • Bee stewardship: Highly toxic to pollinators; never apply to crops during peak flowering hours
  • Protective equipment: Wear chemical-resistant gloves, dust mask, and safety goggles during handling
