Abstract
本发明提供一种含有氯氟醚菌唑和啶酰菌胺的杀菌组合物，氯氟醚菌唑和啶酰菌胺的重量配比为1∶10‑10∶1。本发明的组合物具有明显增效作用，可减少药剂的使用量，降低成本，减少对环境的危害，并有益于抗药性的产生。
Description
技术领域
本发明属于农业化学领域，具体是涉及一种含有氯氟醚菌唑和啶酰菌胺的杀菌组合物。
背景技术
氯氟醚菌唑(Mefentrifluconazole)是一种广谱、高效、内吸，具有铲除和保护作用的新型异丙醇三唑类杀菌剂，属于甾醇脱甲基抑制剂类。与广泛使用的三唑类杀菌剂不同的是，氯氟醚菌唑含有异丙醇结构，可以减少病原菌突变，延缓病原菌的抗药性，有助于延缓杀菌剂的抗性产生和发展；该产品已经在中国、澳大利亚、加拿大、美国、韩国、和欧盟等国家和地区登记，登记作物共计40余种。
啶酰菌胺(boscalid)是新型烟酰胺类广谱杀菌剂，主要用于防治果树和蔬菜的白粉病、菌核病、灰霉病、早疫病等，其通过抑制线粒体生成琥珀酸酯脱氢酶，干扰细胞的分裂和生长，从而起到杀菌作用。
对不同品种的成分进行复配，是防治抗性病害一种常见办法。对不同成分进行复配，再根据实际应用的效果，来判断某种复配是增效、加和还是拮抗，复配增效很好的配方，由于明显提高了实际防治效果，降低了农药的使用量，从而能够大大延缓了病害抗药性的产生，是综合防治病害的重要手段。现有技术中并没有将氯氟醚菌唑和啶酰菌胺复配的相关报道。
发明内容
为解决现有技术中存在的问题，本发明提供的如下技术方案：
一种含有氯氟醚菌唑和啶酰菌胺的杀菌组合物，活性成分包含氯氟醚菌唑和啶酰菌胺，氯氟醚菌唑和啶酰菌胺的重量配比为10∶1-1∶10。
本发明所述的杀菌组合物，氯氟醚菌唑和啶酰菌胺的重量配比优选为1∶5-10∶1。
本发明所述的杀菌组合物，还包含农业上可接受的助剂，活性成分的重量百分含量为5-90％。所述的助剂包括分散剂、乳化剂、崩解剂、稳定剂、防冻剂、润湿剂、增效剂、渗透剂、填料、溶剂。
本发明所述的杀菌组合物剂型为可湿性粉剂、水分散粒剂、水乳剂、颗粒剂、乳油、悬浮剂等。
本发明所述的杀菌组合物用于防治作物病害的用途。特别是用于水稻纹枯病、草莓灰霉病的防治。
与现有技术相比，本发明具有如下有益效果：
本发明的杀菌组合物由两种作用机制不同的有效成分组成，混配后具有明显的协同增效作用，提高了防治效果，同时也有利于克服和延缓病害抗药性的产生。
本发明组合物药剂混配减少了用药量，从而降低了成本和减轻了对环境的污染，安全性好，符合农药制剂的安全性要求。
具体实施方式
下面结合实施例对本发明的具体实施方式进行详细描述，但应当理解本发明的保护范围并不受具体实施方式的限制。
实施例1氯氟醚菌唑和啶酰菌胺对水稻纹枯病菌室内毒力测定
试验对象：水稻纹枯病菌由本公司从田间采集分离纯化获得。
试验方法：应用PDA培养基，先进行预备性试验，然后用无菌水将供试药剂稀释适当浓度的母液、与灭菌的PDA培养基均匀混合、配置药剂浓度呈等比梯度的含药培养基，分别倒入培养皿中备用。用打孔器截取在PDA培养基上培养的待用病原菌菌饼，接种于已凝固的含药PDA培养基中央，置于26℃下培养，待对照菌落直径长至大于平皿直径2/3时，用卡尺测量菌落直径。每个菌落用十字交叉法垂直测量直径各1次，取其平均值。每处理重复4次，与对照比较计算各药剂处理对菌落扩展的生长抑制率。以药剂质量浓度的对数值为横坐标、菌丝生长抑制率的几率值为纵坐标，采用回归分析法对试验数据进行分析，计算各处理的EC50值。
依孙云沛法计算药剂的毒力指数及共毒系数(CTC)。当CTC≤80，则组合物表现为拮抗作用，当80＜CTC＜120，则组合物表现为相加作用，当CTC≥120，则组合物表现为增效作用。
试验结果：表1氯氟醚菌唑和啶酰菌胺对水稻纹枯病菌室内毒力测定
结论与讨论：如表1所示，本发明的杀菌组合物中氯氟醚菌唑和啶酰菌胺的重量比在1∶10-10∶1范围内，对水稻纹枯病表现增效作用；特别是氯氟醚菌唑和啶酰菌胺的重量比在1∶5-10∶1范围内，对水稻纹枯病表现优异的增效作用，其CTC值大于140。
实施例2：氯氟醚菌唑和啶酰菌胺对草莓灰霉病室内毒力测定
试验对象：草莓灰霉病菌由本公司从田间采集分离纯化获得。
试验方法：采用菌丝生长速率法(具体配置方法参考实施例1)、协同效果评价采用CTC法。
试验结果：表2氯氟醚菌唑和啶酰菌胺对草莓灰霉病室内毒力测定
结论与讨论：如表2所示，本发明的杀菌组合物中氯氟醚菌唑和啶酰菌胺的重量比在1∶10-10∶1范围内，对葡萄灰霉病表现增效作用；特别是氯氟醚菌唑和啶酰菌胺的重量比在5∶1-10∶1范围内，对葡萄灰霉病表现优异的增效作用，其CTC值大于150。
