Access scientific knowledge from anywhere. Despite isoeugenol's promising antimicrobial activity, no studies have yet investigated its mode of antibacterial action at the molecular level. As a consequence, leaves wilt and die, which may lead to impairment of the whole plant and eventually to death of the plant. D. vexans isolates were grown on potato dextrose agar medium and identified based on morphological and cultural characteristics. Development of crop health based Integrated Pest management (IPM) package for managing major pests of cinnamon. Cinnamon (Cinnamomum zeylanicum) bark essential oil (CBEO) has been used for thousands of years in Ayurvedic medicine to soothe aching joints and numb pain.It is still used for similar purposes in India, presumably because of its antiinflammatory property. The effect of cinnamon (Cinnamomum zeylanicum) bark essential oil (CBEO) on human skin cells has not been elucidated. Cinnamon bark in combination with honey, in one study, was proven to have beneficial antibacterial effects on acne-causing bacteria . “Intensity of Leaf Spot and Rough Bark Diseases in Cinnamon Accessions Collected from Major Cinnamon Growing Areas of Sri Lanka”.
