| 摘 要： | 通过对防治泽泻白斑病常用化学农药和生物农药的防治效果及其在药材中的残留进行分析，筛选出泽泻生态防治的最佳药剂，为泽泻绿色、可持续生产和建立生态种植基地提供依据。结果表明：施药2次后春雷霉素防效最好，三唑酮、波尔多液和多抗霉素次之；本试验用量下，采收时药材中已无春雷霉素残留，三唑酮和波尔多液仍有少量残留；三唑酮安全期较长，波尔多液残留难以降解，两种化学农药长期使用易对药材和环境造成影响，存在安全风险。综合防效和残留分析结果，春雷霉素防效好且降解快，是泽泻生产可安全使用的药剂，具有较好的推广应用价值。

| Abstract: | Based on the analysis of the control effects of chemical and biological fungicides and their residues in medicinal materials, we screened out the best fungicides for ecological control of Alisma plantago-aquatica, and provided basis for green and sustainable production and establishing ecological planting base of Alisma plantago-aquatica. The results showed that the control effect of Kasugamycin was the best after 2 times of application, followed by Triadimefon, Bordcaux mixture and Polyoxin; Under the experimental dosage, there was no Kasugamycin residue in the medicinal materials at the time of harvest, and there was still a small amount of Triadimefon and Bordcaux mixture residue; Triadimefon has a long safety period, and the residue of Bordcaux mixture is difficult to degrade. Therefore, the long-term use of the two chemical pesticides is easy to affect the medicinal materials and the environment, resulting in security risks. We integrated the control effect and residue analysis results and found that Kasugamycin has good control effect and rapid degradation. It is a safe fungicide for Alisma plantago-aquatica production and has good popularization and application value. |
