Abstract
本发明公开了一种含氟嘧菌酯的杀菌组合物，有效成分包含氟嘧菌酯和几丁聚糖，两者的重量比为1:30‑30：1，优选为1:10‑10:1，所述的农药组合物在上述比例范围内对黄瓜白粉病的防治表现出较好的防治作用，此外，所述组合物对作物安全，值得在生产上推广应用。
Description
技术领域
本发明涉及一种杀菌组合物，具体涉及的是一种含氟嘧菌酯和几丁聚糖的的杀菌组合物。
发明内容
白粉病是一种广泛发生的世界性病害，生产上主要采用化学农药防治白粉病，目前主要依赖苯并咪唑类、三唑类、甲氧基丙烯酸酯类杀菌剂。然而，长期使用单一种类的杀菌剂会使病害产生不同程度的抗性，防治效果降低。
几丁聚糖，又名甲壳素、海力源，是一类从食用昆虫及海洋生物中提取的甲壳质经脱乙酰基二得到的一种天然阳离子多糖，具有可降解性、良好的成膜性和生物相容性及抗菌、抗肿瘤等生物活性，广泛应用于医药、食品和化工等行业。在农业生产中，几丁聚糖是一种优良的生物源作物保护剂，具有诱导作物体抗性因子的功能，又可以成膜防护空气中的致病菌飘移侵染及有害气体的侵蚀上海。几丁聚糖无毒无害，是具有肥药双重功能的生物调节剂；也是无毒无公害的增稠剂，可以减少制剂生产中增稠剂的使用。
氟嘧菌酯，Fluoxastrobin，为甲氧基丙烯酸酯类杀菌剂，作用机理是线粒体呼吸抑制剂，即通过在细胞色素b和c1间电子转移抑制线粒体的呼吸，在作用于线粒体呼吸的较多杀菌剂中，甲氧基丙烯酸酯类化合物作用的部位与其它不同，因此对甾醇抑制剂、苯基酰胺类、二羧酰胺类和苯并咪唑类产生抗性的菌株有效，但由于其使用成本太高，目前国内应用较少。
目前，由于农业生产上易产生抗性的害虫防治，主要办法是开发与现有农药品种无交互抗性的新农药成分或已有农药品种之间的复配，前者由于所需的开发成本高、周期长，而且目前开发速度远远比不上害虫抗药性产生的速度。因此，对于作用机理不同的农药品种进行混配时一种较佳的选择，通过合理的复配，可以提高防效，减少有效成分用量，节约成本，延缓害虫抗药性的产生，进而能够减轻甚至避免农药对食物和环境的污染。
本申请的发明人对氟嘧菌酯和几丁聚糖的配方筛选进行了深入研究，发现氟嘧菌酯和几丁聚糖进行混配在一定的范围内对多种植物病原真菌具有明显的协同增效作用，经进一步研究完成了本发明。另外，目前尚无关于氟嘧菌酯和几丁聚糖复配的相关报道。
发明内容
本发明的目的在于提供一种适合农业上使用的增效杀菌剂，所述杀菌剂有助于减少农药使用量、节省用药成本，延缓病原菌抗药性的产生和降低对环境的风险。
为解决上述技术问题，本发明采用如下技术方案：一种杀菌组合物，其特征在于，活性成分包含氟嘧菌酯和几丁聚糖，其中，氟嘧菌酯和几丁聚糖的质量比为1:30-30：1，优选为1:10-10：1。
进一步的，所述杀菌组合物中活性成分所占的重量百分含量为1-90%，优选为10-50%。
进一步的，所述杀菌组合物可以通过农药制剂加工中常规的制备方法加工成农业上允许的任意剂型，例如可以是可湿性粉剂、水分散粒剂、水乳剂、微乳剂、悬浮剂。
本发明的组合物可以以成品制剂形式提供即组合物中各物质已经混合，也可以以单剂形式提供，使用前直接在桶或罐中按比例混合，然后稀释至所需要的浓度。
进一步的，本发明的组合物还可以加入其它农用活性成分，例如杀菌剂、杀虫剂、除草剂、肥料等农用活性成分。
本发明的杀菌组合物适用于防除黄瓜白粉病、番茄白粉病、草莓白粉病等多种病害。
与现有技术相比，本发明的农药组合物的有益效果为：
（1）本发明的组合物复配后，在一定的范围内具有明显的协同增效作用，防效与单个活性成分相比有明显的提高；
（2）本发明的组合物中活性成分作用机理各不相同，在有效防治作物病害的同时，可以延缓病原菌抗药性的产生，有利于延缓农药活性成分的使用寿命；
（3）本发明的组合物制备工艺简单，适合实际生产中推广应用。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，本发明用以下具体实施例进行说明，但本发明绝非限于这些例子。以下所述仅为本发明较好的实施例，仅仅用于解释本发明，但不能因此理解为对本发明专利范围的限制。应当指出的是，凡在本发明的精神和原则之内所作的任何修改、等同替换或改进等，均应包含在本发明的保护范围之内，因此，本发明专利的保护范围应以所附权利要求为准。

二、室内毒力测定
试验对象：黄瓜白粉病菌
试验方法：试验参考中华人民共和国行业标准NY/T 1156.11-2008《农药室内生物测定试验准则杀菌剂第11部分：防治瓜类白粉病试验盆栽法》，采用盆栽法测定。
播种感病黄瓜品种，盆栽生长至2片真叶期备用。将配制好的氟嘧菌酯和几丁聚糖母液用0.1%吐温-80表面活性剂水溶液溶解并制备浓度梯度。并设只含溶剂和表面活性剂而不含有效成分的处理作空白对照。药剂处理后24 h，喷雾接种黄瓜白粉病菌孢子悬浮液。孢子悬浮液的配制过程如下：取长满白粉病菌叶片，用加油少量吐温-80表面活性剂的无菌水将孢子洗下，双层纱布过滤，镜检后调制成1×105个/mL的悬浮液。接种后置于恒温室中，在温度24℃条件下培养7天。待空白对照病液率达到80%以上时，分级调查各处理发病情况，计算各处理的病情指数和防治效果。
根据colby公式计算两种药剂的增效情况，试验结果如表1所示。
由表1可以看出，氟嘧菌酯和几丁聚糖在重量比为30：1-1:30的范围内对黄瓜白粉病均表现出较好的协同增效作用，其中，当组合物活性成分重量比为1:10-10:1时，共毒系数均大于140，协同增效作用更明显。
三、田间药效试验
为了更好的验证本发明的实际应用效果，采用本发明实施例的药剂进行防治黄瓜白粉病田间药效试验。
供试药剂：（1）31%氟嘧菌酯·几丁聚糖可湿性粉剂（30：1）；（2）22%氟嘧菌酯·几丁聚糖水分散粒剂（10：1）；（3）15%氟嘧菌酯·几丁聚糖悬浮剂（13:2）；（4）8%氟嘧菌酯·几丁聚糖水乳剂（7：1）；（5）对比文件1:40%氟嘧菌酯悬浮剂；（6）对比文件2：0.5%几丁聚糖水剂。
分别于药后5天、10天调查病情指数并计算防效，试验结果见表2。
田间试验结果表明，本发明实施例的组合物对黄瓜白粉病的防治表现出较好的速效性和持效性。含有氟嘧菌酯和几丁聚糖的农药组合物，在有效成分用量为40g/ hm2时，药后10天对黄瓜白粉病的防效均高于78%，明显由于单个活性成分的防效。同时，在试验期间，供试药剂对黄瓜作物安全，无药害发生，对蜜蜂和天地赤眼蜂等有益生物安全，值得在生产上推广应用。
