Two species of earthworms were kept in Muck, Chicot and Ste-Sophie soils treated with captan 50 W.P. solutions of 700, 1 400 and 2 800 ppm. After a 42-day treatment period, L. terrestris had a 95% survival and A. turgida 100% survival. Using a gas chromatograph method, no captan was detected in tissue extracts of exposed earthworms. Based on the survival rate and the undetected presence of captan in earthworm tissues, we concluded that soil residues of this product are unlikely to be harmful to the animal's ecology.
将两种蚯蚓置于用浓度为700 ppm、1400 ppm和2800 ppm的50%可湿性多菌灵溶液处理过的马粪土、奇科特土和圣索菲土中。经过42天的处理期后，陆正蚓的存活率为95%，膨胀双胸蚓的存活率为100%。采用气相色谱法，在暴露的蚯蚓组织提取物中未检测到多菌灵。基于存活率以及在蚯蚓组织中未检测到多菌灵，我们得出结论，该产品的土壤残留不太可能对动物生态造成危害。
