Group 4 insecticide
Mode of Action
The active ingredient in Actara 240SC is thiamethoxam. Thiamethoxam is a second-generation neonicotinoid. In rigorous third-party trials, thiamethoxam went head-to-head with its leading competitor, imidacloprid, and offered greater protection to new growth because of its faster uptake and longer residual.
Thiamethoxam interferes with a unique receptor site in the insect’s nervous system, the nicotinic acetylcholine receptor. It has both contact and ingestion activity. Insect feeding will stop within hours of contact or ingestion and insect death occurs within 24 – 48 hours.
