Abstract
本試驗係於室內及溫室內，探討菜豆種子藥劑處理對白絹病病菌發育之抑制效果，及對種子發芽與生長之影響，其結果如下：
1. 供試藥劑中制菌效果最優者為 Granosan , Ceresan ，其次為 Arasan , Semesan , Blaes M dust 等， Spergon, Riogen dust 等又次之， Copper Sanoz , Blaes dust-2 , Asozin dust-15 等之抑制效果較遜。
2. 各藥劑處理對增進種子發芽及其生長，以 Semesan 之效果為最著，Arasan , Spergon , Blaes M dust , Copper Sandoz 等次之， Blaes dust-2 又次之， Granosan , Ceresan , Riogen dust , Asozin dust-15 等之效果較劣。
3. 對病原菌發育之抑制及增進種子發芽與生長同時有效者，以 Semesan 為最優，Arasan 次之， Spergon , Blaes M dust 等又次之。
4. 在實際上應用時，當以 semesan 0.3% 最為可取。
The present paper deals with the results of a study on the effectiveness of certain dependable seed protectants which could be espected for control Sclerotium rolfsii Sacc., the causal fungus of southern blight of kidney bean, to promote the seedling emergence and seedling stand after treatment. The seed treatment was made in laboratory and in greenhouse. The summary of the results is exhibited as follows:
1. Fungitoxicity of the seed treated to the development of causal organism was conducted in laboratory. So far as the fungicides employed in the present experi-ments were concerned, Granosan and Ceresan were proved most effective, in addition, Arasan, Semesan and Blaes M dust were more fungitoxic than Spergon and Riogen dust, while Copper Sandoz, Blaes dust-2, Asozin dust-15 give poor protective effectiveness.
2. As to the seed germination tests conducted in greenhouse, Semesan was proved highly promoting the seedling emergence and seedling stand after seed treatment, in addition, Arasan, Spergon, Blaes M dust, Copper Sandoz were more effective than Blaes dust-2, while Granosan, Ceresan, Riogen dust and Asozin dust-15 were less effective.
3. So far as the experimental results obtained from laboratory and greenhouse trials were concerned, Semesan was proved most effective either inhibiting the development of causal organism or promoting the seedling emergence and seedling stand after treatment, in addition, Arasan was more effective than Spergon and Blaes M dust.
4. In practical used with Semesan, it is better to adopt to the dosage at 0.3% (Percentage of dosage is based on the weight of dry seeds).
