进行20%寡聚酸碘水剂防治水稻条纹《枯病试验,结果表明:20%寡聚酸碘对水稻条纹《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。
進行20%寡聚痠碘水劑防治水稻條紋《枯病試驗,結果錶明:20%寡聚痠碘對水稻條紋《枯病具有較高活性,且對水稻無毒害作用。20%寡聚痠碘的EC50、EC90分彆為27.69、169.41 mg/L,與對照藥劑0.5%氨基寡糖素水劑相比,EC50氨/EC50寡、EC90氨/EC90寡(相對毒力指數)分彆為1.21、1.15。
진행20%과취산전수제방치수도조문《고병시험,결과표명:20%과취산전대수도조문《고병구유교고활성,차대수도무독해작용。20%과취산전적EC50、EC90분별위27.69、169.41 mg/L,여대조약제0.5%안기과당소수제상비,EC50안/EC50과、EC90안/EC90과(상대독력지수)분별위1.21、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 oligosaccharide acids agent respectively were 27.69 mg/L and 169.41 mg/L,compared with 0.5%amino oligosaccharins agent,EC50 氨/EC50 寡and EC90氨/EC90 寡(relative toxicity index)were 1.21 and 1.15 respectively.
