| 摘要: |
| 孢子萌发试验证实速保利对赤霉菌分生孢子芽管有强烈的致畸作用。当浓度为100～400μｇ·ｍL－1时，速保利对孢子萌发有抑制作用。抑菌试验结果表明，其对该菌的菌落生长有强烈的抑制作用，属极敏感型。田间药效测定确认该药剂防治小麦赤霉病穗腐对小麦具有良好的保护和治疗作用，其防效与多菌灵防效相当。 |

| Abstract: |
| Sporse germination test showed that Dinieonazole inhibited conidia germination at the concentration of 100～400μｇ·ｍL－1 and caused serious germ-tube distortion.The result of the test on the inhibition ability against fungous hyphae growth of
Fusarium graminearium indicated that it also hads trong inhibition to conobium growth
of Fusarium granearium .Field experiments evidently revealed that Dinieonazole applica-
tion could control head blight of wheat and had protective and curative function against
the pathagen with the sameteetive effeciency as that of Carbendazol. |
