Confidor Insecticide: Imidacloprid 17.8% SL Sucking Pest

Confidor (commonly misspelled as Confider) is a market-leading neonicotinoid insecticide manufactured by Bayer, formulated as Imidacloprid 17.8% SL (soluble liquid). Acting as a competitive antagonist of nicotinic acetylcholine receptors (IRAC Group 4A), it provides rapid systemic knockdown and long residual protection against piercing-sucking insect pests. Indian farmers utilize Confidor extensively in cotton, rice, sugarcane, chilli, and vegetables to control aphids, jassids, thrips, and whiteflies.

Chemical properties and acropetal systemic mode of action

Imidacloprid is readily absorbed by foliage, roots, and seeds, moving rapidly through plant xylem to protect emerging shoots.

  • Binds irreversibly to post-synaptic nicotinic acetylcholine receptors (nAChR, IRAC Group 4A) in insect central nervous systems.
  • Causes sustained neurological stimulation, uncoordinated twitching, paralysis, and death by starvation.
  • Systemic translocation: Protects both upper and lower leaf surfaces, including new growth that emerges after application.
  • Soluble liquid (17.8% SL) formulation: Dissolves completely in water without leaving gritty nozzle-clogging residues.

Registered crops and target sucking pest spectrum

Confidor is approved by CIBRC across major agricultural, commercial, and horticultural crops in India.

  • Cotton: Broad-spectrum control of aphids, jassids (leafhoppers), and thrips during vegetative development.
  • Rice (Paddy): Effective management of brown planthopper (BPH) and whitebacked planthopper (WBPH).
  • Chilli and Vegetables: Control of thrips, whiteflies, and aphids that transmit destructive plant viruses.
  • Sugarcane: Management of sugarcane termites and pyrilla leafhoppers.

Application safety, spray timing, and bee protection

Apply Confidor at the early onset of sucking pest populations before economic injury thresholds are crossed. Because neonicotinoids present high acute toxicity to foraging honeybees, do not apply Confidor during peak crop flowering periods. Operators must wear protective rubber gloves, face masks, and eye protection during spray preparation.

Common questions

What is the technical active chemical in Confidor?

Confidor contains Imidacloprid 17.8% SL, a broad-spectrum systemic neonicotinoid insecticide.

Which insect pests are primarily controlled by Confidor?

It primarily controls sap-sucking insects including aphids, jassids, thrips, whiteflies, and planthoppers.

Why should Confidor not be sprayed during crop flowering?

Imidacloprid is highly toxic to pollinating honeybees; spraying during active flowering can harm bee colonies.
