Incipio Insecticide (Isocycloseram): Paddy Stem Borer

Incipio is an advanced broad-spectrum insecticide formulated as a suspension concentrate (SC) containing the novel active ingredient Isocycloseram (ISOCYCLOACTIVE). Developed specifically for rice farmers, it delivers rapid and long-lasting control against two of the most damaging paddy insect pests: yellow stem borer and leaf folder. Its innovative mode of action overcomes resistance developed against older conventional insecticides.

Active ingredient and novel mode of action

Incipio features a unique chemical profile belonging to the isoxazoline class (IRAC Group 30).

Technical breakdown:

  • Active ingredient: Isocycloseram 18.18% w/w SC (Suspension Concentrate).
  • Biochemical action: Acts as an allosteric modulator of insect GABA-gated chloride channels, causing hyper-excitation, paralysis, and swift mortality of target larvae.
  • Contact and ingestion: Absorbed when larvae feed on treated foliage or come in contact with sprayed leaf surfaces.
  • Extended residual protection: Forms a protective reservoir on rice foliage, shielding plants during peak tillering and panicle initiation.

Target pests and application timing in paddy

The insecticide is approved by CIBRC for critical rice pest management.

Key target pests:

  • Yellow stem borer (Scirpophaga incertulas): Prevents dead hearts during vegetative tillering and white heads during panicle emergence.
  • Rice leaf folder (Cnaphalocrocis medinalis): Stops larvae from rolling and scraping green leaf chlorophyll.
  • Application window: Apply when pest threshold levels are reached, typically during active vegetative tillering and early boot leaf stages.
  • Follow registered label directions regarding dilution and water volume (typically 200 litres of water per acre) for uniform coverage.

Safety gear, resistance management and precautions

Applicators must wear standard personal protective equipment (PPE) including nitrile gloves, goggles, and face masks during mixing and spraying. To maintain chemical longevity, rotate Incipio with insecticides having alternate modes of action. Observe prescribed pre-harvest intervals (PHI) before grain harvesting.
