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.
