General description

L-Fenchone is a monoterpene that occurs in the essential oils of plants such as Lavandula dentate. It shows potent fumigant activity against Sitophilus oryzae and Tribolium castaneum, two most common insects affecting stored products. This ability makes it a promising candidate for the development of biocontrol agents against these insects.
