Antimicrobial Activity of Essential Oils Against Plant Pathogenic Fungi: A Review
DOI:10.30954/2454-4132.1.2020.7
Abstract:
Essential oils are obtained from non-woody parts of the plants, particularly foliage, stem or hydrodistillation. They are complex mixture of terpenoids and variety of aromatic phenols, oxides, ethers, alcohols, esters, aldehydes and ketones that determine the characteristics aroma and odour of the donor plants. Presence of volatile monoterpenes or essential oils in the plants provides an important defense strategy to the plants, particularly against herbivorous insect pest and plant pathogenic fungi. Fungi cause huge amount of yield losses due to their ability to cause serious devastating diseases to the crops. Minimizing their effect on the crops need to get a promising way of controlling them. Therefore, the use of essential oils could be a good option to tackle the challenge of fungal diseases. Essential oils are natural products that are extracted from plants by different methods. They have been used for a long history of time for different purposes. Fungicides used in disease management are expensive for resource-poor farmers andnegatively correlation with ecosystems. Nowadays there is a huge interest to use them as plant protection product to be alternative for new agro-chemicals with large antimicrobial spectrum properties. As we observed from the antifungal trials in different literature, the essential oils have a great antifungal effect on many plant pathogens and inhibited most of the tested plant pathogens in the laboratory. Thus, essential oils could be a control agent for plant fungal diseases and further investigation is required to use in the field. This review summarized that the importance, antimicrobial activity and management of fungi.
