Field control effect of 22.4% fluazole aniline seed treatment suspension on rice diseases
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.
