Active ingredient and novel mode of action
Isocycloseram belongs to the isoxazoline chemical family (IRAC Group 30). It functions as a GABA-gated chloride channel allosteric modulator, binding to a novel target site in insect nerve synapses. By locking chloride channels shut, it causes hyper-excitation, convulsions, rapid paralysis, and pest death without cross-resistance to older chemistries.
- Active ingredient: Isocycloseram 9.2% SC (suspension concentrate)
- Chemical group: Isoxazoline (IRAC Group 30)
- Activity spectrum: Dual action against resistant chewing caterpillars, thrips, and phytophagous mites
Target crops and key pest complexes
- Chili: Black thrips (Thrips parvispinus), yellow thrips, and fruit borer.
