λ-Cyhalothrin（Cat No.:R012610）is a synthetic pyrethroid insecticide widely used in agriculture and public health to control a broad spectrum of pests, including mosquitoes, flies, and crop-damaging insects. It works by disrupting sodium channel function in the insect nervous system, leading to paralysis and death. Known for its rapid action and low application rates, λ-Cyhalothrin is highly effective while minimizing environmental impact. It is used on crops like cotton, vegetables, and cereals and in vector control programs for disease prevention. Its efficacy and residual activity make it a key tool in pest management.
