a)一种或多种脲类衍生物，
b)一种或多种二苯醚衍生物。
Description
本发明涉及一种由脲衍生物Ⅰ和二苯醚衍生物Ⅱ组成的用于植物脱叶的增效混合物，
式中A是一种下式所示的芳杂环基团A-1至A-3
或取代的苯基A-4
式中R1为氢或甲基，R2为氟、氯或溴，n取1、2或3，B为环戊基或环己基或由氟、氯、溴单取代至三取代或未取代的苯基。例如，苯基噻二唑基脲，化学名称为N-苯基-N′-（1，2，3-噻二唑-5-基）-脲（参见西德公开申请DOS 2，506，690和DOS 2，619，861）
当使用试剂（Ⅰ）进行农作物保护和处理时，人们通常希望提高其选择性和可靠性。
本发明的目的之一是提供一种可加强已知药物作用的助剂。
特别是在低温下，活性成分Ⅰ的活性表现出波动;而提高低温下的作用速率将会改善该作用的可靠性。
对于柑桔类作物，橄榄、仁果和核果特别对于棉花，脱除剂对于提高产量有着特殊的意义。
使用二苯醚衍生物Ⅱ，如：5-[2-氯-4-（三氟甲基）-苯氧基]-2-硝基苯甲酸钠与喹啉衍生物一道来调节植物的生长已经在欧洲专利申请208245西德专利申请-3524319中公开。二苯醚衍生物Ⅱ的除莠作用已在许多出版物中公开。例如：在美国专利申请-4036929，西德专利申请-2311638，欧洲专利申请-0040898或欧洲专利申请3416中。欧洲专利申请-0001427指出：一种特别取代的二苯醚，即2，6-二氯-3′-氟-4-三氟甲基-6′-二硝基苯醚，对棉花作物产生干燥和落叶的作用。
我们发现，含有下列有效成分的增效混合物即可达到上述目的，
a）一种或多种式Ⅰ的脲衍生物
其中A为A-1至A-3所示的芳杂环基
或取代的苯基A-4
式中R1为氢或甲基，R2为氟、氯或溴，n取1，2或3;B为环戊基或环己基;还可以是未取代的，或由氟、氯、溴单取代至三取代的苯基，和
b）一种或多种式Ⅱ所示的二苯醚衍生物
其中Z可以是基团
式中R3为氢，碱金属离子或碱土金属离子、取代或未取代的铵、1至4个碳的烷基或总共含1至6个碳原子的烷氧基羰基烷基;R4是含1至4个碳原子的烷基。上述试剂特别适用于植物器官的脱除，尤其是使棉花叶子脱落。
详细地说，在化合物Ⅱ中，R3为氢、钠、乙氧基羰基甲基或乙氧基羰基乙-2-基。除了在R是H成为酸的情况外，也可以用相应的碱金属、铵或碱土金属的盐，碱金属盐的实例是：锂盐、钠盐、钾盐。碱土金属盐的实例是：镁盐和钙盐在铵盐当中，R3为未取代的铵离子或N上的1个或2个或全部3个氢原子被下述取代基置换的铵离子，所述取代基是含有1至4个碳原子的直链或支链烷基，这些烷基又可以被卤素（氯或溴）、羟基或含1-4个碳的烷氧基取代，或者其中两个烷基彼此键合形成五员或六员环，该环还可以含有象氧或氮之类的杂原子。
此外，R3也可以是含1至4个碳的烷基，如：甲基、乙基、丙基，异丙基或丁基，或者也可以是含1至6个碳的烷氧基羰基烷基，如，C1-C3-烷基羰基-C1或C2-烷基，例如甲氧基羰基甲基，甲氧羰基乙基、丙氧基羰基甲基，特别是乙氧基羰基甲基和乙氧基羰基乙-2-基。
R4为C1-C4-烷基，例如：甲基、乙基、丙基或丁基，特别是乙基或甲基。
下面是二苯醚衍生物的例子：
二甲基醚衍生物Ⅱ是商品，或者可按前文引证的先有技术描述的方法制备。
在这种奇特的混合物中，成分Ⅰ和成分Ⅱ的重量比是1∶0.01到1∶50，特别是1∶0.2至1∶20，特别优选1∶0.2至1∶10。
特别有效的混合物含有活性成分N-苯基-N′-（1，2，3-噻二唑-5-基）-脲Ⅰ.1（商品名：Dropp，俗名：苯基噻二唑基脲）和5-[2-氯-4-（三氟甲基）-苯氧基]-2-硝基苯甲酸Ⅱ.1或其钠盐（商品名：Blazer）或Ⅰ.1和乙氧基羰基甲基5-[2-氯-4-（三氟甲基）-苯氧基]-2-硝基苯甲苯酯Ⅱ.5（商品名Superblazer），组分Ⅰ.1和Ⅱ.1或Ⅰ.1和Ⅱ.5分别取重量比为1∶0.2至1∶10较佳。
所要求的纯活性混合物的施用比（没有配伍助剂）取决于植物主干、植物生长的阶段、当地的气候条件以及施用的方法。一般地，脲衍生物Ⅰ的使用比例为0.001～3kg/ha，特别是0.1～1kg/ha。而二苯醚衍生物Ⅱ的使用比例为0.001～3kg/ha。特别是0.01～3kg/ha。通常每公顷所需的活性成分混合物总量不要超过4kg。
举例来说，这种奇特的混合物可以以下列形式使用;直接喷洒的溶液，粉末，悬浊液。包括浓缩水溶液、油状的或其它的悬浊液或分散液、乳液、油分散液、糊剂、粉尘剂、散播剂或粒剂。通过喷洒、雾化、撒粉、撒播或浇注。施用的形式完全取决于用途，在任何情况下都应确保活性成分及细地分散。
适用于制备可直接喷洒溶液，乳液，糊剂或油分散液的溶液，是下列中等到较高沸点的矿物油馏分较为适宜：煤油或柴油，煤焦油、植物或动物油、脂肪族、环状的和芳香族烃基，象苯、甲苯、二甲苯、石蜡、四氢化萘、烃基代萘或它们的衍生物，像：甲醇、乙醇、丙醇，丁醇、氯仿、四氯化碳、环己醇，环己酮、氯苯、异佛尔酮。强极性溶剂，如：二甲基甲酰胺、二甲基亚砜，N-甲基吡咯烷酮或水。
含水的施用形式可通过向浓缩乳液、糊剂、可润湿的粉剂（可喷洒粉剂，油状分散液）中加水的方法来制备。就制备乳液，糊剂或油状分散液而言，或者将活性物质直接，或者是溶解在油或溶剂中，然后通过加入润湿剂，增稠剂，分散剂或乳化剂使其均匀分散在水中。然而，也可以制备由活性物质和润湿剂、分散剂或乳化剂、以及溶剂或油组成的浓缩物，而这一浓缩物可用水来稀释。
适宜的表面活化剂是木素磺酸、萘磺酸、苯磺酸的碱金属盐、碱土金属盐和铵盐，烷基芳基磺酸盐，烷基硫酸酯，烷基磺酸酯，二丁基萘磺酸的碱金属和碱土金属盐，月桂醚硫酸盐、脂肪醇硫酸盐，脂肪酸的碱金属和碱土金属盐，硫酸十六醇盐、硫酸十七醇盐、硫酸十八醇盐、硫酸化酯及醇乙二醇醚盐，磺化萘和萘衍生物与甲醛的缩合物，萘或萘磺酸与酚和甲醛的缩合物，聚氧乙烯辛烷醇醚，乙氧基化异辛基苯酚，辛基苯酚，壬基苯酚，烷基酚聚乙二醇醚，三丁基苯聚乙二醇醚，烷芳基聚醚醇，异十三醇，脂肪醇氧化乙烯缩合物，乙氧化蓖麻油，聚氧乙烯烷基醚，乙氧化聚氧丙烯、月桂醇聚乙二醇醚缩醛，山梨醇酯，木素亚硫酸盐废液和甲基纤维素。
粉剂和散布、涂覆、浸渍的均匀粒剂通过将活性组分结合进固体载体之中的方法来制备。这些固体载体是矿物土，如，硅胶，硅石、硅酸盐、滑石、高岭土、粘土、石灰石、石灰、白垩、胶块粘土、黄土、白土、白云石、硅藻土，硫酸钙，硫酸镁，氧化镁等。还可以是粉状塑料、肥料（如：硫酸铵、磷酸铵、硝酸铵，脲素）、植物产品（如，谷类细粒、磨碎的树皮、木屑、果壳屑）、赛路路粉和其它固体载体。
配方中活性成分的重量百分含量为0.1～95，优选0.5至90。例如：一种药剂含有约10-80%（重量百分比）的活性成分，约30-90%（重量百分比）的固体载体，如果需要，还可含20%（重量百分比）的表面活性剂。如果有必要，这种药剂可稀释至合适的使用浓度。
通过与惯用的制剂助剂混合，即可将该药物以完整配方的形式使用。亦可以筒装的混合物形式来使用
例如：作用和作用速率可用象有机溶剂、润湿剂和油之类的增活填加剂来加强，这样就可使应用时活性组分的比例降低。
药剂主要是通过喷洒在叶子上来处理植物的。例如：可以将其与载体水一起用通常的喷洒方法来实施，喷洒液的用量约为100-10001/ha，也可以将药剂用少量喷洒和超少量喷洒的方法来实施，或者将其以微粒剂的形式来使用。
这样奇特的混合物可作为单一成分来使用，或与其它试剂或其它活性成分混合使用。如有必要，可根据你欲达之目的加入其它的脱落剂，干燥剂，植物保剂或杀虫剂。
我们还发现，如果在这种奇特的混合物中加入下列的活性成分，可以更好地控制棉花干燥和脱叶后出现令人讨厌的再生长现象，而脱叶作用可以成功地被保持甚至提高。
