【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。更多还原

【Abstract】 Sporse germination test showed that Diniconazole inhibited conidia ger-mination at the concentration of 100～400 μg·mL￣(-1) and caused serious germ-tube dis-tortion. The result of the test on the inhibition ability against fungous hyphae growth ofFusarium graminearium indicated that it also had strong inhibition to conobium growthof Fusarium granearium. Field experiments evidently revealed that Diniconazole applica-tion could control head blight of wheat and had protective and curative function againstthe pathagen with the sametective effeciency as that of Carbendazol.更多还原
