Abstract
本发明公开了式(I)的2-[2-(1-氯代环丙基)-3-(2-氯代苯基)-2-羟基丙基]-2,4-二氢-[1,2,4]-三唑-3-硫酮和本说明书中所列的活性物质组(1)到(24)的新的活性物质组合,它们具有很好的杀真菌性能。
Description
本发明涉及新颖的杀菌活性化合物组合,包括已知的2-[2-(1-氯代环丙基)-3-(2-氯代苯基)-2-羟基丙基]-2,4-二氢-[1,2,4]-三唑-3-硫酮和其它已知的杀菌活性化合物,它们很适合于防治植物病原真菌。
文献中已描述过2-[2-(1-氯代环丙基)-3-(2-氯代苯基)-2-羟基丙基]-2,4-二氢-[1,2,4]-三唑-3-硫酮有较好的杀真菌性能(参见,WO96-16 048),但在低使用剂量时,在某些情况下,此化合物的活性并不理想。
此外,据文献报道许多三唑衍生物、苯胺衍生物、二羰基亚胺和其它杂环可用于防治真菌(EP-A 0 040 345,DE-A 2 201 063,DE-A 2 324010,《农药手册》[Pesticide Manual],第9版(1991),第249和827页,US-A 3 903 090和EP-A 0 206 999),在低使用剂量时,这些化合物的活性同样不能令人满意。
还已知1-[(6-氯-3-吡啶基)-甲基]-N-硝基-2-咪唑烷亚胺可用于动物害虫如昆虫的防治(参见,《农药手册》,第9版(1991),第491页),但迄今未见有关此化合物杀真菌性能的描述。

本发明的活性化合物组合有很好的杀真菌性能,可用于防治植物病原真菌,如:根肿菌纲、卵菌纲、壶菌纲、接合菌纲、子囊菌纲、担子菌纲、半知菌纲等。
本发明活性化合物组合尤其适合于防治谷类植物病害如白粉菌、柄锈菌和镰刀菌,和葡萄栽培中的病害如钩丝壳霉病、单轴霉病和葡萄孢,也可用在双子叶作物上防治白粉病和霜霉病真菌以及叶斑中的病原有机物。
在防治所需浓度下植物对活性化合物组合有很好的耐药性,因此可用于植物地上部分、繁殖茎和种子处理。也能用于叶面处理或种子包衣。
本发明活性化合物组合可制成常见剂型,如溶液、乳剂、悬浮剂、粉剂、泡沫剂、糊剂、颗粒剂、气雾剂和包于聚合物中和包于用于种子的包衣组合物中的微囊剂以及超低容量喷雾剂型。
这些型剂可以用已知的方式生产,例如,将活性化合物与扩充剂,即液体溶剂、加压下的液化气和/或固体载体混合,并任选使用表面活性剂,即乳化剂和/或分散剂和/或泡沫形成剂。在用水作扩充剂的情况下,也可以用有机溶剂作助溶剂。适合的液体溶剂主要有:芳族化合物,如二甲苯,甲苯或烷基萘,氯代芳族化合物或氯代脂肪烃,如氯代苯类、氯乙烯类或二氯甲烷,脂族烃,如环己烷或石蜡,例如石油馏份,醇类,如丁醇或乙二醇以及其醚和酯,酮类,如丙酮、甲乙酮、甲基异丁基酮或环己酮,强极性溶剂,如二甲基甲酰胺或二甲基亚砜,以及水。液化气扩充剂或载体应理解为是指在常温和常压下是气体的液体,例如气雾剂抛射剂如卤代烃,或是丁烷、丙烷、氮气和二氧化碳。适合的固体载体是:例如磨碎的天然岩石如高岭土、粘土、滑石、白垩、石英、硅镁土、蒙脱石或硅藻土,和磨碎的合成矿物质,如高分散二氧化硅、矾土和硅酸盐。适合用于颗粒剂的固体载体有:例如压碎并分级的天然矿物质如方解石、大理石、浮石、海泡石和白云石,以及有机和无机粉的合成颗粒,和如下有机物的颗粒:锯木屑、椰壳、玉米穗轴和烟茎。适合的乳化剂和/或泡沫形成剂是:例如非离子和阴离子乳化剂,如聚氧乙烯脂肪酸酯、聚氧乙烯脂肪醇醚,例如,烷芳基聚乙二醇醚,烷基磺酸盐,烷基硫酸盐,芳基磺酸盐以及白蛋白水解产物。适合的分散剂是:例如,木素亚硫酸废液和甲基纤维素。
制剂中可以使用粘合剂如羧甲基纤维素和粉状、颗粒或乳胶形式的天然和合成聚合物,如阿拉伯胶、聚乙烯醇和聚乙酸乙烯酯,以及天然磷脂,如脑磷脂和卵磷脂,和合成磷脂。其它的粘合剂可以是矿物油和植物油。
也可能使用染料,如无机颜料,例如氧化铁、氧化钛和普鲁士蓝,和有机染料,如茜素染料、偶氮染料和金属酞菁染料,和微量营养素如铁、锰、硼、铜、钴、钼和锌的盐。
制剂中通常含有按重量计0.1至95%的活性化合物,优选0.5至90%。
剂型中,本发明活性化合物组合可以以与其它已知活性化合物混合的混合物形式存在,其它已知的活性化合物如杀真菌剂、杀虫剂、杀螨剂和除草剂,也可作为与肥料及植物生长调节剂的混合物。
本发明活性化合物组合可以以其原样、其制剂形式或由此制剂制备的使用形式使用,如直接可用溶液、乳油、乳剂、悬浮剂、可湿性粉剂、可溶性粉剂颗粒剂。它们可以以常规的方式使用,例如通过浇水、喷雾、弥雾、撒施、涂抹,也可以作为用于干种子处理的粉剂、作为用于种子处理的溶液、用于种子处理的水溶性粉剂、用于淤浆处理的水溶性粉剂,或进行包衣。
当使用本发明活性化合物组合时,取决于施用的类型,施用剂量可以在相对宽的范围内变化。在处理植物部分时,活性化合物组合的施用剂量通常在0.1至10,000g/ha,优选10至1000g/ha之间。在处理种子时,活性化合物的施用剂量通常在0.001至50g/kg种子,优选0.01至10g/kg种子之间。在处理土壤时,活性化合物的施用剂量通常在0.1至10,000g/ha,优选1至5000g/ha之间。
从下面的实施例中可以明显看到,本发明活性化合物组合显示很好的杀真菌活性,而单个活性化合物的杀真菌活性较弱,本发明组合的活性超过各化合物活性的简单加和。
当活性化合物组合的杀真菌活性超过各活性化合物单独使用时的活性之和时,则总是存在杀菌剂的协同作用。
两个活性化合物组合后的预期活性可按下面方法计算(参考:Colby,S.R.,“Calculating Synergistic and Antagonistic Responsesof Herbicide Combinations”,Weed 15,(1967),20-22)
如果
X为在
m g/ha使用剂量下施用活性化合物A产生的效力,
Y为在
n g/ha使用剂量下施用活性化合物B产生的效力,
E为在
m+
n g/ha使用剂量下施用活性化合物A+B产生的效力,
则
效力以%计算,0%是指效力与对照的相当,100%是指没有观察到侵染。
如果实际的杀真菌活性超过了计算值,则组合的活性是超加合的,即,存在协同作用。在此情况下,实际观察到的效力一定比按上述公式计算得到的期望效力(E)值要大。
