Abstract
一种制备含铜液体农药的方法。第一步包括形成固体化水溶性铜-硼酸盐络合物。第二步包括使固体化水溶性铜-硼酸盐络合物溶解于水中，直到水中含有浓度为至少0.02重量%的铜。
Description
技术领域
本发明涉及一种制备含铜液体农药的方法及一种含铜液体农药。
背景技术
已知铜具有杀真菌剂的性质。不幸的是氢氧化铜几乎不溶于水，并且因此必须溶解在无机酸及氨中形成盐溶液或铜氨络合物。
发明内容
对使用者无害且对环境无害的含铜液体农药是所需要的。
根据本发明的一个方面，提供了一种制备含铜液体农药的方法。第一步包括形成固体化水溶性铜-硼酸盐络合物。第二步包括使固体化水溶性铜-硼酸盐络合物溶解于水中，直到水中含有浓度为至少0.02重量％的铜。
根据本发明的另一方面，提供了一种含铜液体农药，其由浓度为至少0.02重量％铜的铜-硼酸盐络合物的水溶液组成。
美国专利第6,001279号(Payzant et al)公开了一种制备含有铜和硼的固体化水溶性木材防腐剂的方法。在实验室试验中，已经得到第一个惊奇的发现。发现铜和硼发生化学变化，形成铜-硼酸盐络合物。在溶解度试验中，得到第二个惊奇的发现。发现当铜-硼酸盐溶解在水中时，铜保留在溶液。
附图说明
本发明的这些及其他特征将参考以下附图，通过以下说明而变得明显，附图仅用于说明目的，并不试图以任何方式将本发明的范围限制到所示的一个或多个实施方案中，其中：
图1所示为根据本发明的教导来制备含铜液体农药的方法的流程图。
具体实施方式
现在参考图1描述制备含铜液体农药的优选方法。
第一步包括形成固体化水溶性铜-硼酸盐络合物12。形成该水溶性铜-硼酸盐络合物的方式描述于美国专利第6,001,279号中。第二步包括在含有水16的容器14中溶解固体化水溶性铜-硼酸盐络合物12。优选铜-硼酸盐络合物粉碎成粒状，这将加速固体化水铜-硼酸盐络合物溶解于水中。然后，所得铜-硼酸盐络合物水溶液可转移到小容器18中，从而用作液体农药。铜-硼酸盐络合物中铜和硼酸盐的相对比例可改变，只要所得水溶液中铜的浓度具有用作杀霉菌剂(moldicide)、杀虫剂或用作杀真菌剂的足够毒性。为了用作杀霉菌剂，水中铜的浓度应至少为0.20重量％，从而具有对霉菌有毒的足够毒性。为了用作杀虫剂，水中铜的浓度应至少为0.30重量％，从而具有对虫有毒的足够毒性。为了用作杀真菌剂，水中铜的浓度应至少为0.20重量％，从而具有对真菌有毒的足够毒性。
在最小和最大范围方面，具有功效的最小范围是0.20重量％。当铜含量低于0.20％时，其不具有足够有效的效力。最大范围为1.00％，因为高于此范围的“过量”铜不保持在溶液中。优选范围为0.35重量％至0.50重量％。已经选择此范围的0.35％百分比为较低百分比，因为其有效地作为杀霉菌剂、杀虫剂及杀真菌剂。因为成本原因，已经选择此范围的0.50％百分比为较高百分比。0.60％的百分比不比0.50％百分比更有效，却是更昂贵的。
一旦理解了本发明的教导，本领域技术人员可制备和销售具有固体化水溶性铜-硼酸盐络合物颗粒的容器，同时书面说明在规定量的水中溶解规定量的固体化水溶性铜-硼酸盐络合物，从而形成液体农药。所需的精确颗粒量及精确水量将取决于固体化水溶性铜-硼酸盐络合物的效力。
在本发明中，所用术语“包括”以其无限制意义地指包括跟随该术语的项目，但不排除未提及的项目。用不定冠词“a”修饰一个要素不排除存在超过一个要素的可能性，除非本文中明确要求具有一个和仅一个要素。
对于本领域技术人员来说，可对所述实施方案进行修改而不偏离权利要求书中所限定的本发明精神和范围。
