试验证明,采用35％甲霜安按种子重量0.1％拌种,可以完全免除由霜霉病粒引起的大豆霜霉病系统感染病苗的形成。防除效果达100％。采用80％抑霉灵按种子重量0.3％拌种,效果也在97％以上。 在大面积生产田的初步试验表明,采取抑霉灵拌种措施,由于基本消灭了由系统感染病苗所形成的初次发病中心,可以显著减轻整个生育期间大豆霜霉病的蔓延为害,最终发病严重率比不处理区降低73％,病粒率降低90％。认为这一措施应在不同生产条件下进一步试验验证。
Experiments show that the use of 35% a cream according to seed weight 0.1% seed dressing, can be completely inhibited by downy mildew caused by soybean downy mildew system of infected seedlings. Control effect of 100%. The use of 80% antimycanthenum seeds by seed weight 0.3% seed dressing, the effect is also above 97%. Preliminary experiments in large-scale production fields showed that the introduction of the fungicide seed dressing could significantly reduce the spread of soybean downy mildew during the whole growing period due to the substantial elimination of the initial disease center formed by the systematic infection of the seedling and eventually the disease The serious rate was 73% lower than that of the untreated area and the disease rate was reduced by 90%. That this measure should be further tested under different production conditions.
