Current operator feedback from in-field pesticide application operations conveys limited information and often does not allow the operator to visualize a true representation of their performance. Farm management information systems (FMIS) typically do not account for overlap, varying application rates across the width of the spray boom during turns, or off-rate errors due to controller response. The pesticide application coverage training (PACT) tool was developed to deploy data analytics methodologies to sprayer operational data collected during field applications. The goal was to compare enhanced feedback via the PACT tool versus data generated from commercially available FMIS software today. Data were collected for multiple Nebraska fields and processed by the PACT program which consisted of a novel MATLAB program developed for this project. The PACT program successfully generated high-resolution as-applied maps and the automated application report further quantified the contributions of these errors to the total error to illustrate how overlap, turning errors or controller response issues may have individually affected application accuracy. PACT program output metrics were compared with current data provided by FMIS software. Field-average metrics were not found to be significantly different when comparing the PACT program to the FMIS output; however, when examining how in-field errors were distributed amongst various application rate ranges, significant differences were noted in comparison to the FMIS output. Thus, the PACT program was able to quantify and illustrate application rate variation due to boom section overlap and turning movements unaccounted for in traditional FMIS software.

农药应用覆盖培训 (PACT) 工具：喷雾器性能诊断工具的开发和评估

当前来自现场农药施用操作的操作员反馈传达的信息有限，并且通常不允许操作员直观地反映其性能的真实表现。农场管理信息系统 (FMIS) 通常不考虑重叠、转弯期间喷杆宽度上的不同施用率或由于控制器响应引起的停机率错误。农药应用覆盖培训 (PACT) 工具的开发目的是将数据分析方法用于在田间应用期间收集的喷雾机操作数据。目标是将通过 PACT 工具增强的反馈与当今商用 FMIS 软件生成的数据进行比较。收集内布拉斯加州多个油田的数据，并由 PACT 程序处理，该程序由为该项目开发的新型 MATLAB 程序组成。PACT 程序成功生成了高分辨率的应用地图，自动化应用报告进一步量化了这些误差对总误差的贡献，以说明重叠、转向误差或控制器响应问题如何单独影响应用准确性。PACT 计划输出指标与 FMIS 软件提供的当​​前数据进行了比较。将 PACT 计划与 FMIS 输出进行比较时，未发现现场平均指标有显着差异；然而，在检查现场误差在不同施用率范围内的分布情况时，发现与 FMIS 输出相比存在显着差异。因此，
