Active ingredient and novel synaptic mode of action
Isocycloseram is classified under IRAC Group 30 as a GABA-gated chloride channel allosteric modulator. It binds tightly to a distinct target site in the insect neuromuscular junction, locking chloride channels in a closed state. This triggers uncontrollable nervous hyper-excitation, rapid feeding paralysis, and death without cross-resistance to older chemistries.
- Active constituent: Isocycloseram 9.2% SC (suspension concentrate)
- Chemical family: Isoxazoline (IRAC Group 30)
- Activity spectrum: Dual efficacy against chewing lepidoptera, flower thrips, and mites
Approved target crops and key pest complexes
- Chili: Black thrips (Thrips parvispinus), yellow thrips (Scirtothrips dorsalis), and fruit borer.
- Cotton: Resistant thrips complexes, spotted bollworms, and semiloopers.
- Tomato and brinjal: Fruit borer, pinworm (Tuta absoluta), and whiteflies.
- Cabbage and cauliflower: Diamondback moth (Plutella xylostella) and cabbage loopers.
Application timing and rainfastness
Apply when pest pressure reaches economic injury levels, using calibrated hollow cone nozzles to achieve thorough foliar coverage. The formulation is rainfast within one hour of drying. Always observe CIBRC label-approved dosages and mandatory pre-harvest intervals before picking produce.
