<unk>  is an organic compound that is used as a pesticide. It is a pyrethroid, a class of man-made insecticides that mimic the structure and insecticidal properties of the naturally-occurring insecticide pyrethrum which comes from the flowers of chrysanthemums. Synthetic pyrethroids, like lambda-cyhalothrin, are often preferred as an active ingredient in insecticides because they remain effective for longer periods of time.  It is a colorless solid, although samples can appear beige, with a mild odor. It has a low water solubility and is nonvolatile.  It is used to control insects in cotton crops.
