Development of bactericides and fungicides in terms of isolation and identification of substances is an important area of research. Presently, under the concept of integrated pest management, all possible plant pest and disease control methods are integrated to minimize the excessive use of synthetic chemicals and also the incidence of disease. The potential of various essential oils against Gram-positive and Gram-negative bacteria and fungi is being actively investigated in various laboratories across the world. Rice the most important crop, suffers from huge yield losses due to blast and blight diseases. Most of the labs have focussed to use transgenic approaches, the use of environmentally friendly natural products, as disease control strategies. In this context, we propose to evaluate the antimicrobial properties of essential oils and their ability to control diseases of rice. Seven Essential oils from seven different plants were selected for the study. The antimicrobial activity was assessed in terms of their antibacterial activity towards non-pathogenic bacteria and pathogenic drug resistant bacteria by means of their ability to sensitize the drug resistant bacteria in plasmid curing and, ß-lactamase inhibition and as antifungal agents. In conclusion, out of the seven essential oils used, lemongrass, palm rosa and eucalyptus were found to be good antimicrobial agents.
就物质的分离和鉴定而言，杀菌剂和杀真菌剂的开发是一个重要的研究领域。目前，在综合病虫害管理的概念下，整合了所有可能的植物病虫害防治方法，以尽量减少合成化学品的过度使用以及疾病的发生率。世界各地的各个实验室都在积极研究各种精油对革兰氏阳性菌、革兰氏阴性菌和真菌的潜力。水稻是最重要的作物，由于稻瘟病和疫病遭受巨大的产量损失。大多数实验室都专注于使用转基因方法以及使用环境友好的天然产物作为疾病控制策略。在此背景下，我们提议评估精油的抗菌特性及其控制水稻病害的能力。本研究选取了七种来自不同植物的精油。通过它们在质粒消除中使耐药菌致敏的能力、β-内酰胺酶抑制作用以及作为抗真菌剂的能力，评估了它们对非致病细菌和致病耐药细菌的抗菌活性。总之，在所使用的七种精油中，柠檬草、玫瑰天竺葵和桉树被发现是良好的抗菌剂。
