摘　　要：进行20%寡聚酸碘水剂防治水稻条纹叶枯病试验,结果表明:20%寡聚酸碘对水稻条纹叶枯病具有较高活性,且对水稻无毒害作用。20%寡聚酸碘的EC50、EC90分别为27.69、169.41 mg/L,与对照药剂0.5%氨基寡糖素水剂相比,EC50氨/EC50寡、EC90氨/EC90寡(相对毒力指数)分别为1.21、1.15。20% iodine oligosaccharide acids agent was used to control sheath blight of rice ,the results showed that 20% iodine oligosaccharide acids agent against sheath, blight of rice ,which had higher activity,and safety effect on rice. EC50 and EC90 of 20% iodine otigosaccharide acids agent respectively were 27.69 mg/L and 169.41 mg/L, compared with 0.5% amino oligosaccharins agent, EC50 t/EC50 t and EC90t/EC90 t （relative toxicity index）were 1.21 and 1.15 respectively.
