本发明涉及用于改进作物保护配制品和桶混施用与液体肥料相容性的方法，该方法通过(i)将螯合剂加入作物保护配制品中，或(ii)当将该作物保护配制品与该液体肥料混合时添加螯合剂。
Description
技术领域
本发明涉及用于改进作物保护配制品和桶混施用与液体肥料相容性的方法。
背景技术
如本文所用的液体肥料是包含促进植物生长的营养素的任何水基组合物。营养素典型地区分为主要常量营养素[氮(叶生长)、磷(根、花、种子、果实的发育)、钾(强壮的茎生长、植物中水的运动、促进开花和结果)]、次要常量营养素[钙、镁和硫]以及微量营养素[铜、铁、锰、钼、锌、硼]。存在许多不同种类的液体肥料，例如仅包含主要常量营养素N、P和K[其根据它们的组成典型地分类为NP、NK、PK或NPK肥料]或者仅包含微量营养素或包含二者的液体肥料。液体肥料的组成可能差别很大，因为它们可能针对特定作物。
为了节省时间、劳动力和能源，在所谓的桶混过程中将此类液体肥料与作物保护配制品混合，并且然后在没有添加任何额外的水的情况下将该混合物直接施用到作物上已经成为常见的做法。作物保护配制品通常呈具有相对大量的杀有害生物活性成分的液体浓缩物的形式例如悬浮液浓缩物(SC)或可乳化性浓缩物(EC)，或者作为固体颗粒剂例如水可分散颗粒剂(WG)和水溶性颗粒剂(SG)。当在桶混过程期间将作物保护配制品分散在液体肥料中时，它们倾向于立即絮凝或出油(oil out)。已经开发了一些肥料相容剂用于加入作物保护配制品中或者在桶混过程期间添加。这些肥料相容剂的目的是使得作物保护配制品与液体肥料更相容。在市场上作为在桶混施用期间的后添加或者作为已加入试剂的最常用的肥料相容剂是磷酸酯和APG(烷基多糖苷)。然而，当农民不仅可以选择市场上的各种各样的液体肥料，还可选择针对目标作物的肥料或微量营养素的定制共混物时，这些肥料相容剂展现了有限的通用性。通常，一种肥料相容剂不能很好地与所有活性成分和所有类型的作物保护配制品一起使用。除非将作物保护配制品专门配制为耐电解质的，否则浓缩的作物保护配制品在分散到液体肥料中时将立即絮凝或出油。
因此，迫切需要改进作物保护配制品与液体肥料相容性的方法。
具体实施方式
作物保护(CP)组合物通常作为具有相对高浓度的一种或多种活性成分的液体浓缩物或者作为固体颗粒剂商业化。典型的液体作物保护配制品包括但不限于：
-悬浮液浓缩物(SC)
-种子处理用的可流动性浓缩物(FS)
-胶囊悬浮液(CS)
-可乳化性浓缩物(EC)
-微乳剂(ME)
-悬乳剂(SE)
-可分散性浓缩物(DC)
-可溶性浓缩物(SL)。
典型的固体作物保护(CP)组合物包括但不限于：
-水分散性颗粒剂(WG)
-水溶性颗粒剂(SG)
-水溶性粉剂(SP)。
当施用液体或固体CP配制品时，常见的做法是在没有添加任何额外的水的情况下将CP组合物直接分散在液体肥料中。液体肥料是具有高离子强度的高电解质溶液。离子强度取决于液体肥料中离子的浓度和电荷。正由于此，难以将CP配制品分散在液体肥料中。通常，CP配制品会絮凝或出油，或者在液体肥料中分散后显示出另外的不利影响。这是重要的，因为CP配制品与液体肥料的此类混合物将被使用常见的喷雾设备作为喷雾混合物来施用。例如，CP配制品的絮凝将导致喷嘴和管的堵塞。这意味着，在现实生活中，具有此类不足的CP配制品不能与液体肥料直接进行商业施用。对于此类CP配制品这是显著的商业缺陷。因此，一些组合物具有已加入至组合物中的所谓的肥料相容剂(参见背景技术部分)。然而，许多肥料相容剂通用性不强，即，它可能对一种特定的液体肥料起作用，但是对其他不起作用。因此，当在喷雾前将CP配制品与液体肥料混合时，对于该问题存在更普遍适用的解决方案。
现在已出人意料地发现，将螯合剂直接加入CP配制品中或者在桶混过程期间添加螯合剂对于CP配制品的肥料相容性具有显著的有益影响。已意外地发现，将螯合剂添加至CP配制品中显著地改进了肥料相容性，因此该CP配制品可以变得与液体肥料混合时相容，而之前在混合时观察到絮凝或沉降。
因此，在第一个方面，如实施例1，提供了一种用于改进作物保护配制品与液体肥料相容性的方法，所述方法包括
(i)将螯合剂加入作物保护配制品中，或
(ii)当将所述作物保护配制品与所述液体肥料混合时添加螯合剂。
在实施例2中，提供了螯合剂用于改进作物保护配制品与液体肥料相容性的用途，其通过
(i)将螯合剂加入作物保护配制品中，或
(ii)当将所述作物保护配制品与所述液体肥料混合时添加螯合剂。
如本文所用的术语“作物保护配制品”包括液体和固体CP配制品二者。上面给出了二者的实例。最常见的液体CP配制品是SC和EC，并且最常见的固体CP配制品是WG和SG。然而，根据实施例1所述的方法可以适用于任何典型的CP配制品。“作物保护配制品”通常包含一种或多种杀有害生物活性成分，包括杀昆虫剂、杀真菌剂、杀细菌剂、除草剂、杀螨剂、杀线虫剂、驱蠕虫剂和植物生长调节剂。根据实施例1所述的方法适用于任何类型的杀有害生物活性成分。
如本文所用的术语“螯合剂”是含有至少两个选自氧、氮和硫的杂原子并且能够捕获或螯合一个或多个金属原子阳离子的化合物。此外，根据本发明使用的螯合剂，当它们(i)被加入CP配制品中或(ii)当将CP配制品与液体肥料混合时添加时是呈非金属化形式的。
如本文所用的术语“螯合剂”能够形成酸加成盐，并且具有至少一个酸性基团的那些能够与碱形成盐。与碱的合适的盐是金属盐，特别是碱金属盐和碱土金属盐如钠、钾或镁盐。因此，如本文所用的“螯合剂”通常包含多个选自羧酸、羟基、硫醇、磷酸及其衍生物如盐衍生物的基团。
根据本发明特别合适的“螯合剂”选自氨基多羧酸螯合剂、芳香族羧酸螯合剂、脂肪族羧酸螯合剂、氨基酸螯合剂、醚多羧酸螯合剂、磷酸螯合剂、羟基羧酸螯合剂和二甲基乙二肟。螯合剂可以呈酸或盐的形式。

在实施例6中，提供了螯合剂用于改进作物保护配制品与液体肥料相容性的用途，其通过
(i)将氨基多羧酸螯合剂加入作物保护配制品中，或
(ii)当将所述作物保护配制品与所述液体肥料混合时添加氨基多羧酸螯合剂，其中

特别地，根据实施例1至6中任一项所述的方法或用途中的CP配制品选自悬浮液浓缩物(SC)、水包油乳液(EW)、油包水乳液(EO)、悬乳剂(SE)、可溶性液体(SL)、油分散剂(OD)、可乳化性浓缩物(EC)、胶囊悬浮液(CS)、水可分散性颗粒剂(WG)以及水溶性颗粒剂(SG)。在根据实施例1所述的方法的一个实施例中，CP配制品选自悬浮液浓缩物(SC)和可乳化性浓缩物(EC)。在根据实施例1所述的方法的另一个实施例中，CP配制品是悬浮液浓缩物(SC)。
根据实施例1至6中任一项所述的方法或用途中的“将螯合剂加入作物保护(CP)组合物中”意指一种或多种螯合剂是该CP配制品的组成部分，即，它们形成了该CP配制品的组分或共配制品(co-formulant)。这是用于改进CP配制品的肥料相容性的优选方法。将要被加入CP配制品中的螯合剂的量和类型可以根据CP配制品的类型变化。本领域技术人员清楚的是，螯合剂需要可溶于CP配制品中，以便能够充当共配制品。当将该CP配制品分散在液体肥料中时，一种或多种螯合剂通常必须溶解在该CP配制品中。技术人员清楚的是，螯合剂的溶解度可能因溶剂不同而有很大差异，并且在水性CP配制品中还可能是pH依赖性的，即，螯合剂可能在低pH下不可溶，但是在高pH下是可溶的。此种溶解度是pH依赖性的螯合剂的实例是例如EDTA，其倾向于在较低pH下形成不溶性盐。此类螯合剂的不溶性盐不仅可能导致施用设备如喷嘴的阻塞，还可能导致螯合剂充当与液体肥料的相容剂的能力降低。
如之前提及的，已加入CP配制品中的螯合剂的量根据具体情况而变化。然而，如果CP配制品是SC，则螯合剂的量典型地为在总CP配制品的1与10重量％之间，特别地在1与7.5重量％之间，更特别地在2与5重量％之间。此外，如果CP配制品是SC，则螯合剂优选为氨基多羧酸螯合剂。因此，如实施例7，提供了根据实施例3所述的方法，其中该CP配制品是SC。
如本文所用的术语“肥料相容剂”包括设计以使得农业配制品与液体肥料更相容的任何试剂。典型的肥料相容剂包括但不限于烷基多糖苷(APG)、磷酸酯、木质素磺酸盐和接枝梳状聚合物。优选的肥料相容剂是APG和磷酸酯，特别是磷酸酯。
当然也可以将另外的肥料相容剂加入CP配制品中。如之前提及的，典型的可商购的肥料相容剂是磷酸酯和APG(烷基多糖苷)。技术人员理解，此类另外的肥料相容剂的选择取决于许多因素，如CP配制品的类型、存在的活性成分以及待使用的液体肥料。因此，如实施例8，提供了一种根据实施例1至7中任一项所述的方法或用途，其中该方法或用途包括将不是螯合剂的另外的肥料相容剂加入CP配制品中。特别地，如实施例9，提供了一种根据实施例8所述的方法或用途，其中该另外的肥料相容剂是磷酸酯或烷基多糖苷。更特别地，该另外的肥料相容剂是磷酸酯。合适的磷酸酯包括或由以下组成：至少一种磷酸化的C7-C12-醇烷氧基化物，特别是C9-C11-醇烷氧基化物，更特别地是C7-C12和C9-C11-支链醇烷氧基化物，甚至更特别地是磷酸化的2-丙基庚醇烷氧基化物。优选的磷酸酯是那些包含平均1至20个乙氧基单元以及0-3个丙氧基单元和/或丁氧基单元的磷酸化的2-丙基庚醇烷氧基化物。更优选地，磷酸酯是如US 8,937,033 B2(参见权利要求11-15)和WO 2019/162353中所披露的。更优选地，如实施例10，磷酸酯选自
(i)
其中M选自H、一价金属离子和R1R2R3R4N+，其中R1、R2、R3和R4选自H、C1-C4烷基和-CH2CH2OH，并且c是数1-20；
(ii)
其中n是数1-3，M选自H、一价金属离子和R1R2R3R4N+，其中R1、R2、R3和R4选自H、C1-C4烷基和-CH2CH2OH，并且c是数1-20；以及
(iii)(i)和(ii)的混合物。
甚至更优选地，如实施例11，根据实施例4-6中任一项所述的磷酸酯包含2至4个乙氧基单元。最优选地，如实施例12，根据实施例4-7中任一项所述的磷酸酯是以下化合物
其中M选自H、一价金属离子和R1R2R3R4N+，其中R1、R2、R3和R4选自H、C1-C4烷基和-CH2CH2OH，并且c是数2-4。
根据实施例8至12中任一项所述的磷酸酯是可商购的，例如以商品名AgrilanTM。根据实施例8至12中任一项所述的已加入农业配制品中的磷酸酯的量根据具体情况而变化。然而，如果农业配制品是悬浮液浓缩物(SC)，则如实施例13，磷酸酯的量典型地为在总农业配制品的5与20重量％之间，特别地在7.5与15重量％之间，更特别地在7.5与12.5重量％之间。
根据实施例1至12中任一项所述的“当将作物保护配制品与液体肥料混合时添加螯合剂”意指螯合剂不是CP配制品的组成组分，而是与CP配制品同时被分散在液体肥料中。重要的是该CP配制品、螯合剂和液体肥料以这样的方式相容：不会立即絮凝或沉降。技术人员理解，该CP配制品和螯合剂必须根据公知常识进行调整，以便避免此类不足。这也是为什么优选将螯合剂加入CP配制品中的方法的原因，因为可以更好地预测和控制潜在的不足。如果可以控制此种絮凝和沉降的不足，则该方法还提供了与液体肥料改进的相容性。
此外，CP配制品通常还包含额外的共配制品如消泡剂、防冻剂、粘合剂、缓冲剂、分散剂、润湿剂、染料、乳化剂、填料、颜料、溶剂、增稠剂。本领域技术人员清楚的是，根据具体情况和需求使用这些共配制品。这些共配制品不应干扰该一种或多种螯合剂改进CP配制品与液体肥料的相容性的功能。
以下实例用来说明本发明。它们不以任何方式限制本发明。

使用以下方法评估桶混相容性：
向玻璃容器中装入根据表2的液体肥料，随后以典型的使用率添加肥料相容的配制品。搅拌混合物以模拟在喷雾桶中的混合，并立即过筛(50目和100目)。基于筛上固体残余物的量，对筛进行视觉和定性评定(通过＝P，边缘(marginal)＝M，或未通过＝F)。然后在保持静置更长期间后，例如静置过夜后再次测试该混合物。
根据以下分类来完成相容性评定：
·通过＝P：筛上没有至极少残余物；这被认为是肥料相容的。
·边缘＝M：筛上有适度的残余物。
·未通过＝F：显著的残余物；这被认为不是肥料相容的。
