Earthworms, which are very helpful in the formation of vegetable mould, though weak in sunlight, are one of the most important living creatures in relation to agricultural crops, wild plants and ecosystem functions. Increased exposure to UV-B on the surface of the earth due to the depletion of stratospheric ozone is known to cause a variety of physiological and morphological responses in plants. In response to ultraviolet radiation, plants are synthesized and exude volatile and non-volatile compounds from their damaged tissues, some of which act as potential toxins to earthworms.Hydroxamic acids, isothiocyanate and indolylacetonitrile as repellents, against earthworms, have been isolated from UV-B damaged maize seedlings, roots of Japanese radish and cabbage shoots.

蚯蚓是与农作物、野生植物和生态系统功能相关的最重要的生物之一，虽然在阳光下很弱，但它对蔬菜霉菌的形成非常有帮助。众所周知，由于平流层臭氧的耗尽，地球表面对UV-B的暴露增加，会引起植物的各种生理和形态反应。植物对紫外线辐射的反应是合成并从其受损的组织中分泌挥发性和非挥发性化合物，其中一些对蚯蚓具有潜在的毒素作用。从UV-B损伤的玉米幼苗、日本萝卜和甘蓝的根中分离出了羟肟酸、异硫氰酸酯和吲哚乙腈作为驱避蚯蚓的物质。
