Many species are pathogenic, causing crop diseases during crop production and spoilage of agricultural products in both commercial and smallholder farming. attack often results into food contamination, yield loss and increases in food insecurity and food prices. Synthetic fungicides have been used as a control strategy for the management of crop diseases caused by pathogens. The negative effects associated with application of many synthetic pesticides has necessitated the need to search for alternative control strategies that are affordable and environmentally safe. Research on medicinal plants as control agents for pathogens has received attention since plants are readily available and they contain wide variety of secondary metabolites that are biodegradable. The activities of solvent extracts, essential oils and compounds from medicinal plants have been tested against phytopathogenic species. A summary of recent information on antifungal activity of plants against species is valuable for the development of biopesticides. This paper reviews the antifungal research conducted on medicinal plants against pathogens, over a 10-year period, from January 2012 to May 2021. We also highlight the challenges and opportunities of using natural products from medicinal plants in crop protection. Several databases (Science Direct and Web of Science) were used to obtain information on botanical products used to control diseases on crops. Keywords search used included natural products, antifungal, , crops diseases, phytopathogenic, natural compounds and essential oil.
许多物种是病原性的，在作物生产过程中导致作物病害，并在商业和小农种植中导致农产品变质。病害的侵袭通常会导致食物污染、产量损失，并增加粮食不安全和粮食价格。合成杀菌剂一直被用作控制由病原菌引起的作物病害的策略。许多合成农药的应用带来的负面影响使得人们需要寻找负担得起且环境安全的替代控制策略。由于植物易于获得且含有种类繁多的可生物降解的次生代谢物，因此将药用植物作为病原菌的控制剂进行研究受到了关注。总结最近关于植物对病原菌的抗真菌活性的信息对于开发生物农药是有价值的。本文综述了 2012 年 1 月至 2021 年 5 月期间，10 年来药用植物针对病原菌开展的抗真菌研究。我们还强调了利用药用植物天然产物进行作物保护所面临的挑战和机遇。几个数据库（Science Direct 和 Web of Science）被用来获取用于防治作物病害的植物源产品的信息。使用的关键词搜索包括天然产物、抗真菌、、作物病害、植物病原菌、天然化合物和精油。
