Simodis Syngenta Insecticide: PLINAZOLIN Uses, Pests & Dose

Simodis is an innovative, high-performance insecticide developed by Syngenta, powered by proprietary PLINAZOLIN technology and containing Isocycloseram (10% DC / dispersion concentrate). It belongs to IRAC Group 30 and delivers unprecedented control of stubborn, resistant thrips, caterpillars, and mites across high-value crops.

Last reviewed: 10 November 2026

PLINAZOLIN chemistry and innovative mode of action

  • Active ingredient: Isocycloseram 10% DC (isoxazoline class, IRAC Group 30).
  • Novel mode of action: Allosteric modulator of GABA-gated chloride channels; binds at a unique receptor site distinct from all older insecticide classes.
  • Overcoming resistance: Highly effective against insect strains with documented resistance to diamides, neonicotinoids, and organophosphates.
  • Broad developmental efficacy: Controls all active life stages including nymphs, larvae, and adult target pests upon contact and ingestion.

Target insect pests and registered crop portfolio

  • Chilli: Unrivalled management of black thrips (Thrips parvispinus), common chilli thrips (Scirtothrips dorsalis), and fruit borers.
  • Brinjal (Eggplant): Exceptional control of destructive fruit and shoot borer (Leucinodes orbonalis).
  • Tomato: Controls fruit borer (Helicoverpa armigera), pinworm (Tuta absoluta), and leaf miners.
  • Cabbage and Cauliflower: Controls resistant diamondback moth (Plutella xylostella) larvae.
  • Cotton: Manages stubborn thrips and bollworm complex.

Application timing, rainfastness, and resistance stewardship

  • Application window: Apply at the early economic threshold level of pest presence before severe canopy scarring or tunnel boring occurs.
  • Sunlight and rain stability: Demonstrates rapid cuticular absorption, remaining rainfast within one hour and resisting intense sunlight breakdown.
  • Water volume: Apply using 150 to 200 litres of water per acre with fine hollow cone nozzles for complete canopy penetration.
  • Stewardship: Practice resistance rotation by limiting applications per crop cycle and alternating with distinct IRAC chemical groups.
