Description

一种颗粒状可食用杀虫剂组合物
技术领域
本发明涉及一种用于输送杀虫剂的制剂和制备这些制剂的方法。特别是一种当害虫食用时可食用并发挥杀虫活性的制剂。
背景技术
食用农药组合物已广泛应用于害虫防治。在这种制剂中，活性剂的损失是该组合物的功效和环境安全性的问题。杀虫剂通常被释放到环境中，并通过挥发、与粘土或有机物结合、微生物降解、化学腐蚀和淋溶等过程而被浪费(去除或破坏)。这显著地降低了可食用农药制剂的有效寿命。可食用杀虫剂组合物引起的另一个问题是，杀虫剂对有益于害虫的有机物通常是有毒的，但在它们自身的权利中不会引起饲料损害。随着杀虫剂的损失，残留的亚致死量杀虫剂的存在会导致杀虫剂在害虫种群中的抗性发展。这一问题可以通过缓释制剂而加重，该缓释制剂产生显著的区域或“亚致死农药浓度”的“热点”。虽然农药从这些制剂中的缓慢释放增加了可食用农药制剂的有效寿命，但它没有解决对非靶标生物的损害或阻力的建立问题。许多持久的疏水性基质材料(例如乙烯- 乙酸乙烯酯共聚物)不能被害虫食用，因此不能用于提供可食性杀虫剂制剂。
发明内容
本发明的目的在于克服现有技术的上述不足而提供一种颗粒状可食用杀虫剂组合物，可以在土壤中保持其形态在1-3年期间，其中包括许多湿/干循环。
本发明的技术方案是：包括亲水性物质的连续亲水性基质相，分散在H中的不连续亲油相；所述连续亲水性基质相为颗粒状和水，所述基质相适合于害虫；和亲油性基质相，包括亲油性载体和农药，优选溶解在亲油性相中；包括70～ 95％重量的亲水性基质相，包括水和亲油相的5～30％重量。包括基于农药的亲油相重量的0.0％至33％重量；颗粒具有至少500克的单独压碎强度；亲油性相包括一个或多个亲油性载体，所述亲油性载体选自氯化烃、聚亚烷基二醇。
所述亲油性相包括至少12个碳原子且具有至少40％氯化度的氯化烃。
所述亲水性物质选自工艺或未加工的谷粒、血液、骨和动物粪便。
所述颗粒的最大尺寸在0.5至10mm。
包括将根据权利要求1的颗粒状农药组合物放置在土壤表面的邻近或下方。
包括将水与亲水相混合形成可变形面团；将亲油相喷到亲水相上并混合；将混合物形成颗粒；将颗粒干燥成机械完整性；所述亲水材料包括纤维，颗粒通过挤压形成。
本发明的有益效果在于：可以在土壤中保持其形态在1-3年期间，其中包括许多湿/干循环。不连续分散的亲油性相增强了油溶性农药的容纳，因为释放的主要屏障将被预期为亲水性基质。
具体实施方式
不连续分散的亲油性相增强了油溶性农药的容纳，因为释放的主要屏障将被预期为亲水性基质。在厚植被区域，颗粒可以被应用到靠近土壤表面的植被茅草。本发明的杀虫剂组合物包括不连续的亲油性相，其典型地含有溶解在其中的农药。亲油性相加速了在干燥时间试验下从基质相的失水速率，这将被描述。在干燥时间中，将水加入到亲水性基质相中，以60％的水分(即水包含120 个单位)来获得200个单位的基质相。在搅拌下，将70℃下的10个亲油性物质喷到基体相上，然后将混合物混合(挤压或压实)。如果需要的话，可以加入淀粉粉末，以确保颗粒保持其物理完整性所需的最小量。将粒料置于70℃的烘箱中，并指出将颗粒干燥60％至10％的时间。合适的亲油性材料是其中干燥时间(与添加无亲油性物质的情况相比)减少了20％或更大的那些材料。使用从水膨胀的亲水性基质相加速水损失率的亲油材料可以导致油溶性农药的增强包容性。本发明的组合物包括由亲水性材料和水组成的连续亲水性基质相。亲水性材料通常是颗粒状固体。优选地，这些颗粒实体包括偏心颗粒，其最大尺寸与最小尺寸的比率至少为2，更优选至少为5。更优选地，亲水性实体包括长度为0.05毫米或更大的纤维或纤维段，最优选的是0.5毫米或更多。连续的亲水相含有水。水可以以亲水性相的至少0.5％重量的量存在，并且优选地以亲水性相的重量的至少5％的量存在。水的优选上限通常由所需的组合物的机械完整性来控制。通常不超过30％的重量。亲水性基质相在用水膨胀时可在高压剪切力作用下形成可变形面团。亲水性基质相对目标害虫是可食用的。亲水性基质可以包括广泛的有机材料，尽管分解的植物材料和植物纤维是特别优选的。亲水性基质可包括可食材料，如稳定的堆肥材料、植物纤维、植物外壳、生的或加工的谷物、血液和骨头、骨粉、泥炭、动物粪便及其混合物。亲水性基质包括泥炭或玉米纤维，优选木质泥炭或芦苇莎草泥炭或泥炭藓泥炭。更优选的是纤维芦苇莎草泥炭。最优选地，亲水性基质包括纤维状泥炭。
