Vermiwash is a liquid extract produced from vermicompost in a medium where earthworms are richly populated. It comprises a massive decomposer bacteria count, mucus, vitamins, different bioavailable minerals, hormones, enzymes, different antimicrobial peptides, etc. This paper aimed to assess how these natural products in vermiwash suppressed the pathogen and pests. Thus, we have reviewed the importance of vermiwash/vermicompost in disease control, the mechanism of disease suppression, the components of vermiwash applied in disease suppression, and pest control to use the scientific facts in agriculture to enhance the productivity of the crops. The bioactive macromolecules from the skin secretion of earthworm, coelomic fluid, and mucus directly able to defend pathogenic soil microbes against the worm and thereby freed the environment from the disease. Earthworms establish symbiotic relations with microbes, produce an essential product that supports the growth of plants, and suppress plant's root disease. It is recomended that earthworm should be inoculated in an agricultural field, or prepare and apply its vermiwash/vermicompost as a spray or as additive bio-fertilizer in the soil to enhance the productivities of the crops.
蚯蚓粪提取液是在蚯蚓大量繁殖的介质中从蚯蚓堆肥中提取的液体。它含有大量的分解菌、黏液、维生素、各种可生物利用的矿物质、激素、酶、各种抗菌肽等。本文旨在评估蚯蚓粪提取液中的这些天然产物是如何抑制病原体和害虫的。因此，我们综述了蚯蚓粪提取液/蚯蚓堆肥在病害防治中的重要性、病害抑制机制、用于病害抑制的蚯蚓粪提取液成分以及害虫防治，以便利用农业中的科学事实提高作物产量。蚯蚓皮肤分泌物、体腔液和黏液中的生物活性大分子能够直接抵御致病土壤微生物对蚯蚓的侵害，从而使环境免受病害影响。蚯蚓与微生物建立共生关系，产生支持植物生长的必需产物，并抑制植物根部病害。建议在农田中接种蚯蚓，或将其蚯蚓粪提取液/蚯蚓堆肥制成喷雾或作为土壤添加剂生物肥料施用，以提高作物产量。
