已发现通式Ⅰ化合物有杀菌活性。从而,本发明进一步提供了含有载体和上面定义的式Ⅰ化合物作为活性成分的杀菌组合物。也提供了制备这种组合物的方法,它包括使上面定义的式Ⅰ化合物与至少一种载体结合。这种组合物可含有单一化合物或本发明几个化合物的混合物。也观察到不同的异构体或异构体混合物也有不同的活性水平或活性谱,并且这种组合物可含有单一的异构体或异构体混合物。
按照本发明的组合物优选含0.5至95%(重量)活性成分。
按照本发明的组合物的载体是满足下述条件的任何物质:它与活性成分配成后便于施用于待处理地的位点,例如可以是植物,种子或土壤;或者有利于贮存;运输或操作。载体可以是固体或液体包括通常是气体但已压缩成液体的物质,和可使用任何通常在配制杀菌组合物中所用的载体。
合适的固体载体包括天然和合成的粘土和硅酸盐,例如天然的硅石如硅藻土;硅酸镁如滑石;硅酸铝镁,例如硅镁土和蛭石;硅酸铝如高岭土,蒙脱石和云母;碳酸钙;硫酸钙;硫酸铵;合成的水合氧化硅和合成硅酸钙或硅酸铝;元素如碳和硫;天然的和合成的树脂如苯并呋喃树脂,聚氯乙烯,和苯乙烯聚合物和共聚物;固体多氯苯酚;沥青;蜡如蜂蜡,石蜡,和氯代地蜡;和固体肥料如酸性磷酸盐。
合适的液体载体包括水;醇如异丙醇和甘醇;酮如丙酮,甲乙酮,甲基异丁酮和环己酮;醚;芳烃或芳脂烃如苯,甲苯和二甲苯;石油馏份如煤油和轻矿物油;氯代烃如四氯化碳,全氯乙烯和三氯乙烷。通常,不同液体的混合物也是合适的。
通常制成杀菌组合物并将其转化为浓缩形式,在施用之前由使用者将其烯释。少量的表面活性剂载体的存在有助于稀释过程。这样,按照本发明的组合物中,至少有一种载体优选是表面活性剂。例如组合物可含有至少两种载体,其中至少一种是表面活性剂。
表面活性剂可以是乳化剂,分散剂或湿润剂;它可以是非离子的或离子的。合适的表面活性剂的例子包括聚丙烯酸和木质磺酸钠或钙盐;分子中含至少12个碳原子的酯肪酸或脂族胺或酰胺与环氧乙烷和/或环氧丙烷的缩合物;甘醇,山梨醇,蔗糖或季戊四醇脂肪酸酯;这些酯与环氧乙烷和/或环氧丙烷的缩合物;脂肪醇或烷基苯酚如对辛基苯酚或对辛基甲苯酚与环氧乙烷和/或环氧丙烷的缩合物;这些缩合产物的硫酸盐或磺酸盐;在分子中含有至少10个碳原子的硫酸或磺酸酯的碱金属或碱土金属盐,优选钠盐,例如硫酸月桂酯钠,硫酸仲烷基酯钠,磺化蓖麻油钠盐,磺酸烷基芳基酯钠如十二烷基苯磺酸酯钠盐;和环氧乙烷聚合物和环氧乙烷和环氧丙烷的共聚物。
本发明的组合物例如可成型为可湿性粉剂,粉剂,颗粒剂,溶液,可乳化的浓缩剂,乳剂,悬浮浓缩剂和气雾剂,可湿性粉剂通常含25,50或75%(重量)活性成分,且通常除固体惰性载体之外,还含有3-10%(重量)分散剂,且若需要加入0-10%(重量)稳定剂和/或其它添加剂如渗透剂或粘着剂,粉剂通常可成型为具有与可湿性粉剂相似的组成但没有分散剂的粉剂浓缩剂,在地里进一步用固体载体稀释,得到通常含1/2-10%(重量)活性成分的组合物。粒剂通常制备成具有10和100BS目(1.676-0.152mm)大小,且可用成团或注入技术制备。通常,粒剂含1/2-75%(重量)活性成分和0-10%(重量)添加剂如稳定剂,表面活性剂,缓释改良剂和粘结剂。所谓的‘可流动干粉’由具有相对高浓度活性成分的相对小的颗粒组成。可乳化浓缩剂除溶剂外,当需要时通常含有共溶剂,1-50%W/V活性成分,2-20%W/V乳化剂和0-20%W/V其他添加剂如稳定剂,渗透剂和腐蚀抑制剂。悬浮浓缩剂通常这样配制以得到稳定的不沉淀的可流动产物,且通常含有10-75%(重量)活性成分,0.5-15%(重量)分散剂,0.1-10%(重量)悬浮剂如保护胶体和触变剂,0-10%(重量)其他添加剂如消泡剂,腐蚀抑制剂,稳定剂,渗透剂和粘着剂,和水和有机液体,活性成分在其中基本不溶;某些有机固体或无机盐可以存在,在配制时溶解,有助于防止沉淀或作为水防冻剂。
水分散剂和乳剂,例如通过用水稀释按照本发明的可湿性粉剂或浓缩剂得到,也列入本发明范围。所说的乳剂可具有油包水或水包油两个类型,可具有如浓‘mayonnaise’似的稠度。
本发明的组合物也有含有其他成分,如具有除草、杀虫或杀菌性能的其他化合物。
使用载体增加本发明化合物的保护活性时间是特别有意义的,载体使杀菌化合物缓慢释放到待保护的植物的环境中。这种缓释剂型可以,例入进入蔓藤植物的根的邻近的土壤中,或者能包括使他们能直接施于蔓藤植物的茎的粘着成分。
本发明还进一步提供上面定义的通式Ⅰ化合物或上面定义的组合物用作杀菌剂和提供了就地消灭真菌的方法,它包括用这种化合物或组合物处理真菌所在地,真菌所在地例如可以是遭到真菌侵害的植物,这种植物的种子或这种植物正在生长或将生长于其中的介质。
本发明在保护作物植物抗真菌方面有广阔的有用性。可以保护的具体作物包括蔓藤,谷类作物如小麦和大麦,苹果和蕃茄。保护的时限通常取决于所选的化合物自身,也取决于多种外部因素,如气候,它的影响通常由使用合适的剂型来减轻。

抗多种植物致病真菌化合物MIC值的测定
MIC值(最低抑制浓度)是采用48孔微量滴定盘,通过系列稀释试验测定的。试验化合物在营养液中的稀释及分配到孔中是由TECANRSP5000自动样品处理机完成的。

100、50、25、12.5、6.25、3.13、1.56、0.78、0.39、0.20、0.10及0.05μg/ml。
营养液的制备,由V8汁(商标名)加碳酸钙中和并离心。上请液用蒸馏水(1∶5)稀释到最终浓度。
真菌(马铃薯早疫病交链孢(Alternaria S0lani)、灰绿葡萄孢(B0trytis Cinerea),麦类颖斑枯病壳针孢霉(Septoria nodorum)以孢子悬浮液的形式滴加到孔中。微量滴定盘在20℃培养6-8天。目测观察该盘决定MIC值。对马铃薯早疫病交链孢和灰绿葡萄孢而言,系列稀释浓度中无菌丝生长的最低浓度被定义为MIC值。对于麦类颖斑枯病壳针孢霉,无MIC值,但仅常常观察到对生长的强烈抑制作用。
