Active ingredient and chemical mode of action
Spinetoram features a unique biochemical mode of action, making it valuable for insect resistance management.
Technical details:
- Active ingredient: Spinetoram 11.7% SC (Suspension Concentrate).
- Mode of action: Allosterically activates nicotinic acetylcholine receptors (nAChRs) at a unique site distinct from neonicotinoids, causing involuntary muscle contractions, tremors, and insect mortality.
- Secondary action: Exhibits minor interactions with gamma-aminobutyric acid (GABA) receptors.
- Translaminar movement: Penetrates treated leaf surfaces, effectively controlling pests feeding on the undersides of leaves.
Target insect pests and registered crops
Spinetoram is approved across high-value horticulture and field crops.
Key registered applications:
- Chilli: Highly effective against western flower thrips and chilli thrips (Scirtothrips dorsalis), reducing leaf curl.
- Cotton: Controls thrips and spotted bollworm larvae.
- Soybean and maize: Controls fall armyworm (Spodoptera frugiperda) and defoliating caterpillars.
- Follow registered label dosage directions; use recommended water volumes (typically 150 to 200 litres per acre) for uniform coverage.
Integrated Pest Management (IPM) and safety
Because of its low toxicity to predatory mites, ladybird beetles, and lacewings once dried, Spinetoram is well-suited for IPM strategies. Applicators should wear protective goggles, nitrile gloves, and face masks during spray preparation. Always observe statutory pre-harvest intervals before picking.
