本发明涉及以下技术领域:用于具有高盐含量的作物保护制剂、特别是除草制剂的增稠剂结合物,和含有所述佐剂结合物的制剂,以及用于制备所述制剂的方法。在优选的实施方案中,本发明涉及水溶性活性成分的含水制剂,特别是盐样活性成分的含水制剂,并且尤其是涉及含有草铵膦和/或草甘膦的制剂,其与至少一种其他水不溶性活性成分(其悬浮在制剂中)结合,其中所述制剂含有高盐含量。
Description
本发明涉及以下技术领域,用于具有高盐含量的作物保护制剂,特别是除草制剂,和含有所述佐剂结合物的制剂,还涉及制备所述制剂的方法。
在一个优选的实施方案中,本发明涉及将水溶性活性成分的含水制剂,特别是盐样活性成分的含水制剂,并且尤其是涉及含有草铵膦和/或草甘膦的制剂,与至少一种其他水不溶性活性成分(其悬浮在制剂中)结合,其中所述制剂含有高盐含量。
用于水溶性活性成分的各种制剂是已知的,特别是用于除草剂如草铵膦和草甘膦的各种制剂。然而,在高负载的制剂中,体系趋于附聚而导致保存期缩短和功效降低以及所述制剂本身的稀释和施用问题。如果分散体中存在第二种活性成分(SC制剂),则此问题将变得更加重要。像黄原胶这样的标准增稠剂不能在这种制剂中起作用,并且导致颗粒附聚。
因此,需要替代的增稠剂体系,其允许制备具有高盐含量并优选具有至少一种其他活性成分的高负载制剂,其提供不会附聚的稳定制剂。
此外,需要所述制剂和用于制备所述制剂的改进方法。
因此,本发明的目的是提供一种增稠剂结合物,其不显示本领域中已知的增稠剂体系对于具有高盐含量的高负载制剂的缺点。此外,目的是提供包含所述增稠剂体系的活性成分的制剂及其制备方法。
现已出人意料地发现,将合成硅酸盐与至少一种选自纤维素、黄原胶和天然硅酸盐的其他增稠剂结合,可以稳定活性成分、特别是除草剂的高负荷高盐含量制剂。

更优选地,根据ASTM D 1208,天然硅酸盐2)的pH为7.0至9.5,更优选为8.0至9.0。
甚至更优选地,天然硅酸盐2)的吸油率(ASTM D281)为110至120,更优选为115。
在一个实施方案中,天然硅酸盐2)包含60-65%SiO2、约11-14%的Al2O3、11-14%MgO以及其他金属和磷氧化物,总计为100%。
BET表面积例如可与在氮的沸点(-196℃)下测量的吸附到颗粒(1g样品)表面的气体的体积相关。吸附气体的量与颗粒的的总表面积(包括表面中的孔)相关。该计算基于BET理论。传统上,氮气用作吸附气体。
优选地,1)与2)的比例为1∶5至5∶1,更优选为1∶3至3∶1,甚至更优选为1∶2至1∶2,并且进一步优选为0.8∶1.2至1.2∶0.8。

根据本发明,本文定义的除草剂结合物或包含本文定义的除草剂结合物的组合物含有除草有效量的所述除草剂结合物,并且可以包含其他组分,例如在作物保护中常用的不同类型的农业化学活性化合物和/或制剂助剂和/或添加剂,或者其可以与这些一起使用。
所使用的活性成分(a)和(b)的类型决定了可通过施用作物保护组合物或农业化学制剂来防治的害虫的类型。就除草剂而言,所述害虫即为不希望的植物。
优选的制剂是那些包含(a)型成分的制剂,所述(a)型成分选自式(1)的一种或多种化合物或其盐,和/或式(2)的一种或多种化合物或其盐,
其中
