<p>感谢二位朋友的热心帮助!施宝功、甲基托布津、代森锌、佳爽等多种杀菌药物已用过,但结果是:第一次使用短期内有效,不久病情复发,再次用药没有多大效果或无效(已产生抗药性);“竹荪抗腐剂”没用过。顺便提一点,有专家<span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">进行病原菌分离、培养、鉴定<span lang="EN-US">,</span>分离到<span lang="EN-US">4</span>种致病真菌</span>:<span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">茄病镰刀菌</span><span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">、绿色木霉</span><span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">、匍枝根霉</span><span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">、拟青霉,也有专家进行了实地诊治,结果也没有根治,不知哪位有杀灭这4种真菌的经验或竹荪球腐烂病的防治经验,望不惜赐一下,小弟不甚感激。</span></p>

<p>用70%甲基托布津、50%多菌灵、施宝功、抑唑霉、70%敌克松等5种杀菌剂进行室内抑菌试验,</p><p>施宝功500倍液对病菌的抑制率分别为71.3%,67.4%,58.7%和73.2%,</p><p>甲基托布津500倍液对以上4种病菌的抑制率分别为68.4%,64.5%,60.7%,63.6%.</p><p>多菌灵、抑唑霉、敌克松的防治效果不明显. </p><p></p><p>网上的资料 不知道有没有参考作用</p><p></p><p></p>
