Eugenol occurs naturally in essential oils such as clove oil, clove basil oil, and cinnamon oil. It is a colorless to light yellow viscous oily liquid with a strong clove and spicy aroma.
The scientific name of eugenol is 4-allyl-2-methoxyphenol. The molecular formula is C10H12O2, and the molecular weight is 164.21. It is a colorless to light yellow viscous liquid with a strong clove spicy aroma. It is slightly soluble in water, miscible with alcohol, ether, chloroform, volatile oil, and soluble in glacial acetic acid and caustic alkali solutions. The color gradually becomes darker and thicker in the air. Metal ions such as iron and zinc can catalyze its oxidation, so the storage temperature should not exceed 25°C and it should be kept away from light. Eugenol can also turn red litmus blue, and it turns blue when it reacts with ferric chloride ethanol solution.
Eugenol Applications
Eugenol is a common pesticide ingredient with a wide range of applications. It is obtained through chemical synthesis and is commonly found in pesticides, fungicides and herbicides in agricultural production.
Insecticidal Effect
Eugenol has a killing effect on a variety of pests. Its insecticidal effect is mainly achieved by destroying the physiological metabolic process of pests, interfering with their nervous system and digestive system, and even causing them to suffocate. Eugenol pesticide is widely used to kill aphids, mites, termites, grubs, and other pests.
Bactericidal Effect
Eugenol has a bactericidal effect, which can prevent the growth and reproduction of pathogens, so as to achieve the purpose of preventing and controlling crop diseases. Eugenol pesticide is widely used in the control of plant diseases, such as bacterial wilt, anthracnose, late blight, gray mold, and so on.
