摘要：

为明确22.4%氟唑菌苯胺种子处理悬浮剂防治水稻恶苗病、立枯病、纹枯病的田间药效,确定最佳使用剂量和安全性。以22.4%氟唑菌苯胺种子处理悬浮剂用量分别为8、10、12 mL·kg-1和对照药剂3.5%咯菌精甲霜悬浮剂制剂用量4 mL·kg-1,进行田间药效对比试验。结果表明,22.4%氟唑菌苯胺种子处理悬浮剂对水稻恶苗病的田间防治效果为80.55%~92.21%,对水稻立枯病的田间防治效果为82.25%~90.11%,对水稻纹枯病的田间防治效果为78.70%~90.77%,增产率为41.25%~55.12%,均显著优于对照药剂3.5%咯菌精甲霜悬浮剂,且对水稻出苗和生长安全、具有显著的促进生长作用。综上所述,22.4%氟唑菌苯胺种子处理悬浮剂拌种防治水稻病害具有较好的效果,生产上建议制剂用量为8~12 mL·kg-1,有效成分用量为1.79~2.69 mL·kg-1。

Abstract:

The aim of this study was to clarify the field efficacy of 22.4% fluazole aniline seed treatment suspension in the control of rice bakanae disease, rice seedling blight and rice sheath blight disease, and to determine the optimal dosage and safety. The dosages of 22.4% fluazole aniline seed treatment suspension agent were 8, 10 and 12 mL·kg-1, and the dosage of control agent 3.5% fludioxin nail cream suspension was 4 mL·kg-1, respectively. The results showed that the field control efficacy of 22.4% fluazole aniline seed treatment suspension on rice bakanae disease was 80.55%-92.21%, 82.25%-90.11% against rice seedling blight, 78.70%-90.77% against rice sheath blight disease, and yield increase rate of 41.25%-55.12%, which were significantly better than those of the control agent 3.5% flurodiin nail cream suspension, and had a significant growth promotion effect on rice seedling emergence and growth. In summary, 22.4% fluazole aniline seed treatment suspension seed dressing has a good effect on the control of rice diseases, and the recommended dosage of preparation is 8-12 mL·kg-1 and the dosage of active ingredient is 1.79-2.69 mL·kg-1.
