Plant virus diseases, known as 'plant cancer', are the second largest plant diseases after plant fungal diseases, which have caused great damage to agricultural industry. Since now, the most direct and effective method for controlling viruses is chemotherapeutics, except for screening of anti-disease species. As the occurrence and harm of plant diseases intensify, production and consumption of pesticides have increased year by year, and greatly contributed to the fertility of agriculture, but also brought a series of problems, such as the increase of drug resistance of plant pathogens and the excessive pesticide residues. In recent years, biopesticide, as characterized by environmentally safe due to low residual, safe to non-target organism due to better specificity and not as susceptible to produce drug resistance due to diverse work ways, has gained more attention than ever before and exhibited great development potential. Now much progress has been made about researches on new biogenic anti-plant-virus substances. The types of active components include proteins, polysaccharides and small molecules (alkaloids, flavonoids, phenols, essential oils) from plants, proteins and polysaccharides from microorganisms, polysaccharides from algae and oligochitosan from animals. This study summarized the research advance of biogenic anti-plant-virus substances in recent years and put forward their further development in the future.
植物病毒病被称为“植物癌症”，是仅次于植物真菌病害的第二大植物病害，给农业产业造成了巨大损失。到目前为止，除了筛选抗病品种外，控制病毒最直接有效的方法是化学治疗剂。随着植物病害的发生和危害加剧，农药的生产和使用量逐年增加，这在极大促进农业丰产的同时，也带来了一系列问题，如植物病原体耐药性增加以及农药残留超标等。近年来，生物农药因其残留低对环境安全、特异性强对非靶标生物安全、作用方式多样不易产生耐药性等特点，受到前所未有的关注并展现出巨大的发展潜力。目前，新型生物源抗植物病毒物质的研究已取得诸多进展。其活性成分类型包括植物来源的蛋白质、多糖和小分子（生物碱、黄酮类、酚类、精油）、微生物来源的蛋白质和多糖、藻类来源的多糖以及动物来源的壳寡糖。本研究综述了近年来生物源抗植物病毒物质的研究进展，并对其未来的进一步发展提出了展望。
