Abstract
本发明涉及具有植物生长调节性能的季铵盐的新颖的混合物。用来调节植物生长的该盐以及其它活性成分溶解于具有描述于下文的式Ⅱ(a)或Ⅱ(b):HO-B-OH的溶剂中,其中Ro是氢或C1-C18-烷基,n是0、1、2或3,A是C1-C6-亚烷基或C1-C6-氧基亚烷基,m是1、2、3、4或5,B是直链或支链C2-C8-亚烷基。
Description
本发明涉及具有生长调节性能的新混合物,更具体地说,涉及新颖的季铵盐与生长调节活性成分在适合溶剂中的新的生长调节混合物。本发明还涉及调节植物生长的方法。
植物生长调节剂(“植物生长调节剂”)在作物栽培、农业和园艺领域有许多的有用用途。例如,在栽培诸如谷物、玉米、向日葵和大豆等作物时的一个特别关心的问题是由于在收获前不利的天气条件造成的倒伏问题。抑制植物的纵向生长就使茎变厚、变强壮,因此减小倒伏的危险。同样,通过抑制棉花作物的纵向生长,成熟的过程可以得到控制,以便进行完全的机械化收获。
果树的生长调节可以产生减少修剪的费用,同时还能使种植者限定果树年产量的波动。
一些植物生长调节剂还可以通过改善抗霜性来控制作物对不利天气条件的敏感性。这点对冬天的谷物特别有用。过分的纵向生长和过于茂盛的叶片发育使植物更易于被霜冻。因此,甚至在有利的生长条件下,例如在播种后和冬天打霜前,也同样希望抑制生长。这样就便植物不易被霜冻。除了增加抗霜冻性外,相对小的叶片和植物量也使其不易染病如感染真菌病害。作物的调节生长还使许多作物能更加密地种植在一起,从而在给定面积内的产量更高。
这些化合物可以其水浓缩物或片剂或颗粒剂形式从商业上得到(例如,PIX植物生长调节剂,BASF公司)。这些化合物可以通过本领域已知的方法制备,例如,通过用甲基卤来转化仲或叔胺。无水制备甲哌鎓(它可以在加工中用作固体填充料)的方法描述于EP-0573177A2中,该文并入本文以作为参考。

一用作生长调节化合物的特定化合物是下式表示的前己二酮(prohexadione):
在此,前己二酮包括化合物(IUPAC名)3,5-二氧代-4-丙酰基环己烷羧酸(或3,5-二氧代-4-(1-氧代丙基)环己烷羧酸(C.A.名))和3-羟基-4-prionyl-5-氧代-3-环己烯羧酸及其药理学有效的盐如盐酸盐、硫酸盐、metrab、乙酸盐、碳酸盐、氢化物、氢氧化物、钠盐、钾盐、钙盐、镁盐、钡盐、铝盐、镍盐、铜盐、锰盐、钴盐、锌盐、铁盐或银盐。
其它的具有生长调节性能的酰基环己二酮化合物描述于美国专利US4693745中,该文并入本文作为参考,且由下式表示:其中R7是-OR9或-NR10R11基,R8是C3-C6-环烷基,R9,R10和R11各相互独立地是氢、C1-C6-烷基、C1-C6-卤代烷基、C2-C10-烷氧基烷基、C2-C10-烷硫基烷基、C3-C6-烯基,后者是未取代或由卤素、C1-C4-烷氧基或C1-C4-烷硫基取代;C3-C6-炔基、苯基或C1-C6-芳烷基,其中苯环是未取代或由卤素、C1-C4-烷基、C1-C4-烷氧基、C1-C4-卤代烷基、硝基或氰基取代;R10和R11之一是甲氧基;或R10和R11与它们连接的氮原子一起形成5-或6-元杂环状环系,该环系在环上可以含有另外的氧或硫原子,及其金属或铵盐。
刚在上文提到的化学式的特定化合物包括由下式表示的抗倒酯(酸)(IUPAC名4-环丙基(羟基)亚甲基-3,5-二氧代环己烷羧酸)且优选其乙酯,抗倒酯(IUPAC名4-环丙基(羟基)亚甲基-3,5-二氧代环己烷羧酸乙酯;CA名4-(环丙基羟基亚甲基)-3,5-二氧代环己烷羧酸乙酯)
活性成分与诸如式I(a)和I(b)的季铵盐的混合物描述于EP0434613A2中。虽然这些混合物提供有用且有益的性能,但仍寻求活性化合物的混合物的更优的稳定性。
因此,本发明的目的是通过将式I(a)和/或I(b)盐样活性成分组合在溶液中,同时保持活性成分的稳定性,来创造一种具有生长调节性能的制剂。本发明的另一目的是通过将式I(a)和/或I(b)成分与式III活性成分或与式IV或V的酰基环己二酮组合而获得生长调节性,并保持活性成分的稳定性。
本发明提供这样的制剂,其中盐样活性成分,如式I(a)和I(b)的季铵盐,溶解于适合的有机溶剂中,其中其它的带有调节性能的活性成分,如式III、IV或V的那些,也可以加入其中,同时保持活性成分的充分稳定性。虽然已知由于盐样活性成分如季铵盐的极性、盐样及无机特性,其溶解于水中,但这些水溶液会造成用在生长调节混合物中的其它活性成分降解。
HO——B——OH II(b)其中
Ro是氢或C1-C18-烷基,
n是0、1、2或3,
A是C1-C6-亚烷基或C1-C6-氧基亚烷基,
m是1、2、3、4或5,和
B是直链或支链C2-C8-亚烷基。
虽然这些溶剂能充分溶解式I(a)和/或I(b)的盐样活性成分,它们还是式III、IV和V活性成分的良好溶剂。此外,已发现,使用这些溶剂使这些活性成分在溶液中有良好的稳定性。通过将式I(a)和或I(b)的盐样活性成分与式III、IV和/或V的化合物组合可以发现有特别的优点。获得了生长调节性能并且混合物充分维持活性成分的稳定性。这些制剂优选在基本上无水存在的条件下提供的。

式II(a)的溶剂可以包含芳族醇或醚的衍生物。芳族醇优选是其OH基通过具有1至4个碳原子的亚烷基或具有2至6个碳原子的氧基亚烷基连接于芳环上。在一些情况下,苄基醇、乙二醇单苯基醚、丙二醇单苯基醚、丁二醇单苯基醚及它们在芳环上由1到3个C1-C3-烷基取代的衍生物,具有特别的优点。
式II(b)的溶剂可以包含带有C2-C8-亚烷基链的直链或支链二醇。二个羟基可以位于该链的端部或内部。式II(b)的优选代表是丙二醇或丁二醇。相比之下,活性成分在这些溶剂中的稳定性稍优于在乙二醇中。
式II(a)和/或II(b)溶剂在本发明制剂中的量优选占制剂总量的按重量计20-99%,优选按重量计35-98%,且特别是按重量计50-96%。

本发明的另一项优选实施方案涉及一种制剂,该制剂包含式III(d)和/或其碱金属、碱土金属或铵盐。
本发明的混合物还可以具有按重量计多达30%且优选按重量计多达20%的其它加工辅助剂组分,这些组分是本领域技术人员已知的,例如,EPA434613中提到的辅助剂,该文并入本文以作为参考。
当使用表面活性物质作为另外的加工辅助剂时,可以考虑的物质是芳族磺酸例如木素磺酸、苯酚磺酸、萘磺酸和二丁基萘磺酸的碱金属、碱土金属和铵盐,和脂肪酸、烷基磺酸和烷基芳基磺酸、烷基月桂基醚硫酸和脂肪醇硫酸的碱金属、碱土金属和铵盐,以及硫酸化的十六-、十七-和十八醇或脂肪醇乙二醇醚的盐,磺化萘和其衍生物与甲醛的缩合产物,萘或萘磺酸与苯酚和甲醛的缩合产物,聚氧乙烯辛基酚醚、乙氧基化的异辛基-、辛基-或壬基酚、烷基苯酚或三丁基苯基聚乙二醇醚,烷基芳基聚醚醇、异十三烷醇、脂肪醇环氧乙烷缩合物,乙氧基化蓖麻油,聚氧乙烯烷基醚或聚氧丙烯烷基醚、月桂醇聚乙二醇醚乙酸酯、山梨醇酯,木素亚硫酸盐废液或甲基纤维素。
本发明的制剂可以用本领域技术人员已知的方法制备,例如通过将式I(a)和/或式I(b)化合物和式III、IV和/或V活性成分和其它加工辅助剂加入到式II(a)和/或式II(b)溶剂中,同时搅拌,并任选同时加热,而制备。
本发明制剂的优选应用是用有效量的基于式I(a)和/或式I(b)活性成分,或式I(a)和/或式I(b)活性成分与式III、IV和/或V成分的混合物的制剂在出苗前或出苗后处理植物。拌种是本发明的另一种可能应用。
取决于不同的季节、目标作物和生长期,施用的混合物的量可以介于0.0001至1.0,优选0.001至0.5,且特别优选0.001至0.1kg/ha的范围内。
本发明混合物实际上可以各种方式作用于植物的所有发育阶段,且因此用作生长调节剂。作用的多样性取决于下列因素:
(1)植物的种类与品种;
(2)施用的时间,相对于植物发育期和一年中的季节而言;
(3)施用的位点和施用的方法(如拌种、土壤处理、叶面施用或树干注射);
(4)气候因素,如温度、降雨量和昼长和光强度;
(5)土壤性能,包括施肥;
(6)活性物质I(a)和/或I(b)和/或式III和/或IV和/或
V,特别是III(a)和/或III(b)的浓度。
在大量的本发明混合物或含有之的药剂在作物栽培、农业或园艺中的应用中,可以提到以下几种。
使用这些混合物和药剂,植物的植物性生长可受到严重抑制,这点可以用纵向生长减少来表示。因此,处理的植物表现出矮化生长和叶片变得更绿。
再者,本发明混合物可以造成在处理的植物中内源乙烯形成减少。这导致:-延迟渐老现象,因此使插花的生命延长,并增加作物的同化期,从而增加收获量;-减少或至少暂时延缓叶片、花和果的脱落;-改善豆科作物的根节形成,因此可更强地从空气中吸收氮;-降低对压力环境(如缺水、低温、机械压力、被有害真菌或昆虫侵害)的敏感性。
同样,用本发明混合物可增加植物部分和植物成分物质的产量。因些也可能例如诱导更大量的芽、花、叶、果实、种籽、根和节的生长,增加糖甜菜、甘蔗、柑橘属水果中糖的含量,增加谷物或大豆的蛋白含量,或增加棉花的纤维素产量。
本发明混合物还可以通过干扰植物代谢或通过促进或抑制植物性和/或繁殖生长,带来产量的增加。
同样,用这些混合物,不仅可以缩短或延长发育阶段,而且也可以在收获前或后,加快或延迟收获的植物部分成熟。因此,例如更集中的棉铃成熟时间可以更利于种植者收获。
植物对水的消耗也可以通过实施本发明而减少。这点对于需要高费用地人工灌溉的农业区,如干旱或半干旱的地区而言是特别重要的。通过使用本发明的药剂,可以减少灌溉的强度,使农田管理费用降低。在本发明药剂的影响下:
-气孔开口宽度减小;
-形成更厚的表皮和角质层;
-改善土壤中根的繁殖;
-种植大田的微环境受更密的生长的影响而更有利。
本发明混合物可以从种子(作为种子拌种剂)或经由土壤(即通过根)且优选通过喷雾施用于植物。由于施用方法的多样性,本发明混合物可以用在许多作物上。
在制备混合物时,优选是使用纯的式I(a)和/或I(b)和式III、IV和/或V的活性成分,其中也可以加入其它活性成分,如调节植物生长的活性成分、除草活性成分和保护植物不受有害真菌或动物害虫侵害的活性成分,或肥料。
因此,式I和III、IV或V化合物可以联合施用。
本发明的另一个方面包括这样的制剂,该制剂包含(a)一或多种具有选自上面提到的式II(a)和II(b)化学式的溶剂和(b)具有选自上面提到的式III、IV和V的化学式的调节植物生长的活性成分。
这些制剂显示,当这些活性成分溶解于本发明的溶剂中时,它们获得的非常好的稳定性。
这些制剂可包含上面提到的季铵盐作为其它活性成分。
下文实施例给出盐样活性成分如式I(a)和I(b)的化合物在溶剂如式II(a)和II(b)的溶剂中的溶解性,和活性成分如式III、IV和V在溶剂如式II(a)和II(b)溶剂中的稳定性。更具体地说,实施例1-17,如表1中给出的,显示甲哌鎓在各种溶剂中的溶解性。将按重量计15%的甲哌鎓加入100克每一种溶剂中,观察是否发生完全溶解。
表1 | ||
实施例序号 | 溶剂 | 15wt%溶液的溶解度 |
1V | 水 | 溶解 |
2V | 异丙基* | 溶解 |
3V | 乙二醇 | 溶解 |

17 | 丙二醇 | 溶解 |
V=对比实验
*=通常,由于其低沸点和闪点,异丙醇和短链醇较不适合用于植物农药的制剂。
特别出人意外的发现,正如表1中所示,是活性成分甲哌鎓在苄醇(实施例14)中与在环己基甲醇(实施例13V)中相比的溶解性。由于环脂族环结构类似于活性成分的结构,本领域技术人员会预期在环己基甲醇中的溶解性会比在苄醇中的要好。
其中R1和R2是甲基且R3是CH2COOCH3(III(a))的式III活性成分在各种溶剂中的稳定性示于下文实施例18-24中,如表2所示。为测定稳定性,将含按重量计10%的各活性成分的溶液在54℃温度下贮存14天,之后用HPLC测定残留的活性成分含量,计算相对于原始含量的百分率。
表2 | ||
实施例序号 | 溶剂 | 残留的活性成分含量(%) |
18 | 水** | <0.1 |
19 | 乙二醇 | 80.2 |
20 | 环己醇 | 99.7 |
21 | 丙二醇 | 95.2 |
22 | 苄醇 | 96.5 |
23 | 乙二醇单苯基醚 | 99.5 |
24 | 丙二醇单苯基醚 | 100.0 |
**由于溶解性的原因,活性成分含量仅为4%。
这些实施例显示,当这些活性成分溶解于本发明溶剂时,获得非常好的稳定性。
在实施例25-29中,用各种溶剂制备本发明混合物制剂。这些溶液含有按重量计5%的活性成分甲哌鎓和用于实施例18-24中的活性成分。这些活性成分的稳定性用与上述实施例18-24描述的方法测定。结果示于表3中:
表3 | ||
实施例序号 | 溶剂 | 残留的活性成分含量(以式III(a)活性成分的%计) |
25 | 乙二醇 | 63.8 |
26 | 丙二醇 | 91.8 |
27 | 苄醇 | 98.8 |
28 | 乙二醇单苯基醚 | 99.4 |
29 | 丙二醇单苯基醚 | 99.8 |
这些实施例证实,通过使用选自式II(a)和/或II(b)的溶剂,可以制备出组合制剂,其一方面是盐样活性的极性且特征上更似无机物的活性成分的充分溶剂。而且,这些制剂可以允许与式I(a)和/或I(b)活性成分一起加入选自式III、IV和/或V的活性成分,而不对活性成分III、IV和/或V的稳定性造成不利影响。
参考其优选的实施方案,对本发明作了相当详细的描述。然而,在本发明的精神与范围内,在不偏离前述说明书与权利要求书中描述的本发明的情况下,可以作许多变化或改进。
