Lambda-Cyhalothrin is a high-efficiency, broad-spectrum insecticide. B2B buyers should prioritize Technical Grade (TC) with a purity of ≥95% or formulated products like Emulsifiable Concentrates (EC), Wettable Powders (WP), or Capsule Suspensions (CS). Ensure the isomer ratio is correct, as the biological activity depends on the specific chemical configuration. For agricultural use, the acidity/alkalinity (pH value) must be controlled between 5.0 and 8.0 to ensure chemical stability during storage.
