Chemical constituents and toxicity of Agastache foeniculum (Pursh) kuntze essential oil against two stored-product insect pests

The uncontrolled use of synthetic insecticides is a great hazard for the environment and consumers. Essential oils were introduced as low toxic agents against mammals and non-targeted insects. In this study, essential oil from aerial parts of blue giant hyssop (Agastache foeniculum [Pursh] Kuntze) (...

Essential oils were introduced as low toxic agents against mammals and non-targeted insects.
