NPDRS Generic Template Project
In this project phase, Neil McRoberts, Carla Thomas, and Judy Brown conducted activities to evaluate the outcomes and assess the effectiveness of new NPDRS plans. Using a systematic approach, the gold standard lead authors rated the plans and compared the results with previous rankings to identify any improvements or downgrades. The history of the project details the collaborative efforts of plant pathologists in creating parameters to differentiate NPDRS plans, leading to the identification of key characteristics and the formation of distinct plan groups. The continuous refinement process aims to enhance the quality and effectiveness of NPDRS plans for better disease management.

NPDRS Generic Template Project Phase 3 Neil McRoberts Carla Thomas Judy Brown
Phase 2 Outcomes Plant Disease Feature Article published on process, the 37 characters, and the four resulting plan groups Air-borne Soil-borne Actively vectored Passively vectored
Phase 3 Activities Gold Standard Lead Authors rated the 6 new NPDRS plans that were written since the generic project began. These rankings were combined with the 14 rankings of gold standards in Phase 2. The results were compared with the results of the 14 rankings in phase 2 to see if additional plans improved or degraded the 4 groups of plans.
Project History Phase 1 - create a set of parameters that are key to differentiating categories of NPDRS plans A team of five plant pathologist met and identified 37 Characteristics that separated the existing 14 plans into 4 different groups. Four of the team then rated each plan topic for the 37 characters for each of the 14 existing plans. A sixth plant pathologist ran a principal coordinates analysis of ratings. 4 groups emerged. Phase 2 14 additional plant pathologists rated each plan for the 37 characters for each of the 14 existing plans. The lead author (gold standard) for each plan was asked to rate their plan for the 37 characters. The four groups remained and the clusters were statistically more significant when 14 additional ratings were added. The gold standard ratings analysis maintained the same 4 groups. A Plant Disease Feature Article was published on these findings. Phase 3 Six new plans were created in the interim. Lead authors rated their own plan for the 37 characters. An analysis of all 21 gold standard ratings was conducted. Manuscript in preparation describing statistical approach as Special Report for Plant Disease.
