特别优选化合物I.12,I.23,I.32和I.38。
在结构式II中,R是氢或卤素原子如氟、氯、溴和碘,特别是氢、氟和氯,更优选氢或氟。
相对C=N双键,结构式II化合物以反式E或顺式Z两种构型(就羧酸功能基团)存在。因此,本发明混剂中既可以使用它们的纯反式或顺式异构体,也可以是反式/顺式异构体的混合物。优选使用反式/顺式异构体混合物或反式异构体,特别优选的是反式异构体。
在化合物II的侧链中肟醚基团的C=N双键可以纯的反式或顺式异构体也可以以反式/顺式异构体的混合物存在。本发明混剂中使用的化合物II可以是两种异构体的混合物,也可以是纯的单-异构体。就它们的使用来说,化合物II特别优选侧链中的两个肟醚基团都是反式构型的那些化合物(E/E)。
由于氮原子的基本特性,化合物I和II可以与无机或有机酸或金属离子形成盐或加合物。
无机酸的例子包括氢卤酸如氢氟酸、盐酸、氢溴酸和氢碘酸、硫酸、磷酸和硝酸。
适合的有机酸,例如,甲酸,碳酸和链烷酸,如乙酸、三氟乙酸、三氯乙酸和丙酸,还有乙醇酸、硫氰酸、乳酸、琥珀酸、柠檬酸、苯甲酸、肉桂酸、草酸、烷基磺酸(1-20个碳原子的直链或支链烷基磺酸)、芳基磺酸或芳基二磺酸(芳香基团,如苯基和萘基,带1或2个磺酸基团)、烷基膦酸(1-20个碳原子的直链或支链烷基膦酸)、芳基膦酸或芳基二膦酸(芳香基团,如苯基和萘基,带1或2个磷酸基团),烷基或芳基可以进一步带有取代基,例如,对-甲苯磺酸、水杨酸、对-氨基水杨酸、2-苯氧基苯甲酸、2-乙酰氧基苯甲酸等。
适合的金属离子,特别是,第一至第八副族的元素离子,特别是铬、锰、铁、钴、镍、铜和锌,以及第二主族的元素,特别是钙和镁,和第三和第四主族元素,特别是铝、锡和铅。这些金属可以存在各种可接受的价态。
制备这些混剂时,优选使用纯活性成分I和II,如需要可以混合其它抗有害真菌或害虫如昆虫、蜘蛛或线虫的活性成分,或除草剂或植物生长调节活性成分或肥料。
化合物I和II的混剂,或化合物I和II同时,结合或分开使用,表现了对广谱的植物病原真菌的突出的杀菌作用,特别是来自子囊菌纲、担子菌纲,藻菌纲和半知菌纲的真菌。其中一些药剂是系统作用,因此也可作为叶面和土壤使用的杀菌剂。
控制各种农作物上的大量真菌是非常重要的,例如棉花、各种蔬菜(如黄瓜、蚕豆、番茄、马铃薯和葫芦)、大麦、草皮、燕麦、香蕉、咖啡、玉米、各种果树、水稻、黑麦、大豆、葡萄、小麦、观赏植物、甘蔗和各种种子。
特别适合控制以下植物病原真菌:禾谷类作物上的禾白粉菌(白粉菌)、葫芦上的二孢白粉菌和单丝壳白粉菌、苹果上的白叉丝单囊壳菌(苹果白粉菌)、葡萄上的葡萄钩丝壳菌、禾谷类作物上的柄锈菌属、棉花,水稻和草坪上的丝核菌属、禾谷类作物和甘蔗上的黑粉菌属、苹果黑星菌(斑点病)、禾谷类作物上的长蠕孢属、小麦的颍枯壳针孢菌(小麦颍枯病)、草莓,蔬菜,观赏植物和葡萄上的灰葡萄孢[原文如此](灰霉病)、落花生尾孢(花生褐斑病)、小麦和大麦眼斑(基腐)病、稻梨孢菌、致病疫霉引起的马铃薯和番茄晚疫病、葡萄生单轴霉(葡萄霜霉病)、啤酒花和黄瓜上的假霜霉属、蔬菜和水果上的链格孢属、香蕉上的球腔菌属以及镰孢属和轮枝孢属真菌。

使用实例1
对小麦叶锈病菌的杀菌活性
在盆栽的品种为“Frühgold”的小麦苗叶片上,喷洒叶锈病菌孢子粉(Puccinia recondita)。此后,将花盆放于高空气湿度(90-95%)的温室中,20-22℃保持24小时。在这段时间,孢子萌发并且萌发管穿透叶组织。第二天,由含有10%活性成分,63%环己酮和27%乳化剂的储备溶液制成的活性成分水剂喷施被侵染植物至全部润湿。喷施后,药膜干燥,将试验植物孵育在65-70%相对湿度的温室中,20-22℃7天。然后观察锈菌在叶片上的扩展。
评估是以侵染叶片面积百分比为标准。将这些百分比转换成杀菌效果。使用Abbot公式计算杀菌效果(E):
E=(1-α)·100/β
α等于处理后的植物受真菌侵染%和
β等于未处理(对照)植物的真菌侵染%。
杀菌效果0表示相对于未处理对照植物的侵染水平;杀菌效果100表示处理植物并未被侵染。
使用Colby公式计算活性成分混剂的预期杀菌效果,并与观察的杀菌效果相比较[R.S.Colby,Weeds 15(1967),20-22]。
Colby公式:E=X+Y-X·Y/100
E预期杀菌效果,当使用活性成分A和B的混剂,浓度为a和b时,
以未处理对照%表示
X杀菌效果,当使用活性成分A,浓度为a时,以未处理对照%表示
Y杀菌效果,当使用活性成分B,浓度为b时,以未处理对照%表示
试验结果列于表2和3中。
