Abstract
本申请公开了一种含水农药浓缩物,其包含农药(例如茁长素除草剂)、表面活性剂和天然或石油衍生的油,还公开了引入该浓缩物的含水农药喷雾混合物的用途。此处公开的含水农药浓缩物包括:5至90wt%的农药(例如茁长素除草剂),0.1至20wt%的表面活性剂和0.1至20wt%的天然或石油衍生的油。该含水农药浓缩物是稳定的水包油乳液,其在稀释进入喷雾溶液后形成稳定的乳液。
Description
背景技术
通过经济且可用的技术实现的农业喷雾使用水力喷嘴,该喷嘴本身可产生宽范围的喷雾液滴尺寸。发现这些喷雾液滴从初始期望的施用位点漂移的可能性与液滴尺寸有关,其中越小的液滴越倾向于偏离目标运动。大量研究成果(包括众多田地试验,风洞测试和之后建立预测数学模型)已经进一步增强了对喷雾液滴尺寸和偏离目标漂移潜力之间的关系的理解。尽管其它因素例如气象条件和喷杆(sprayboom)高度也会影响漂移潜力,但是已经发现喷雾液滴尺寸分布是主要的因素。Teske等人(TeskeM.E.,HewittA.J.,Valcore,D.L.2004.TheRoleofSmallDropletsinClassifyingDropSizeDistributionsILASSAmericas17thAnnualConference:ArlingtonVA)已经报告了<156微米(μm)的值是产生漂移的喷雾液滴分布的分数(fraction)。RobertWolf(Wolf,R.E.,KeystoSprayDriftManagement,PowerPointPresentation(文件名:DriftMinimization–2009),可于此阅读www.bae.ksu.edu/faculty/wolf/drift.htm,上次浏览为2013年10月8日)引用了<200μm的值作为可漂移分数(driftablefraction)。因此,充分估计很可能产生漂移的液滴尺寸为低于约150μm的分数。
可以很明显的是偏离目标运动的不利结果。已经证明一些除草剂在极低的份每一百万份(ppm)或甚至份每十亿份(ppb)水平对特定的植物品种具有非常敏感的植物毒性,因此在敏感性作物、果园、和住宅区种植物周围需要受限制施用。例如,加利福尼亚农药监管部(CaliforniaDeptofPesticideRegulation)规定,在圣华金河谷(SanJoaquinvalley)空中施用含敌稗(propanil)的除草剂的缓冲区为1/2-2英里。

最佳喷雾液滴尺寸取决于对于使用农药组合物的应用。如果液滴过大,则喷雾的覆盖率将会较小;即,大的液滴将会降落在某些区域,而介于其间的区域将会受到极少喷雾覆盖或没有喷雾覆盖。最大可接受的液滴尺寸可取决于每单位面积待施用的组合物的量以及对喷雾覆盖均匀性的需要。较小的液滴提供较均匀的覆盖率,但是较倾向于在喷雾过程中漂移。因此,必须使施用参数例如喷雾覆盖均匀性与较小液滴漂移的趋势相平衡。例如,如果在喷雾过程中是特别多风的,则可能需要较大液滴以减少漂移,而在较平静的天气则可接受较小的液滴。
除了具体的含水农药喷雾组合物的物理性质之外,喷雾液滴尺寸还可取决于喷雾设备,例如,喷嘴尺寸和构造。喷雾漂移的减少可源自多种因素,包括减少细喷雾液滴(最小直径<150μm)的产生和增大喷雾液滴的体积中值直径(VMD)。在任何情况下,对于给定的喷雾设备、施用和条件,并且基于脂肪酸烷基酯和/或甘油三脂肪酸酯,使用此处描述的组合物和方法产生的多个喷雾液滴的中值直径增至高于不包括此处描述的脂肪酸烷基酯、甘油三脂肪酸酯或石油衍生的油的喷雾组合物的中值直径。
