Thiamethoxam 97% TC is a high-purity, broad-spectrum systemic insecticide belonging to the neonicotinoid class. It is designed to control a wide range of sucking and chewing insect pests, including aphids, whiteflies, thrips, leafhoppers, mealybugs, and beetles, across a variety of crops such as vegetables, cereals, cotton, rice, and fruits.
It works by interfering with the normal functioning of the insect's nervous system, leading to paralysis and death. Due to its systemic action, it is rapidly absorbed and translocated through the plant’s vascular system, providing both protective and curative activity. Thiamethoxam is valued for its long residual effect, fast action, and compatibility with integrated pest management (IPM) programs.

Thiamethoxam acts on nicotinic acetylcholine receptors (nAChRs) in the insect’s central nervous system. It binds to these receptors, causing overstimulation, which leads to paralysis and ultimately death. As a systemic insecticide, it is absorbed by roots and leaves, offering protection to both new and existing plant tissue.
