Non Technical Summary
As part of a multi-state effort, practices (cultivars, pesticides, etc.) for managing economically-important plant-parasitic nematodes in crops will be evaluated through field trials and related research. Results will be extended to stakeholders.

Goals / Objectives
Integrate nematode management agents (NMAs) and cultural tactics with the use of resistant cultivars to develop sustainable crop production systems.
Project Methods
Field trials are the primary method for my contribution to this project of evaluating nematode management practices. For these field trials, nematode management practices (cultivars, nematicides, etc.) will be tested against non-treated controls and commercial standards (as available) in replicated experiments. Management practices will be evaluated by assessing nematode populations (through soil or root analysis as appropriate for the given crop), crop growth, and final crop yield. This trials will be conducted primarily in small-plot trials, but will also include on-farm, larger split-plot trials to test management practices on a commercial scale. Trials will be repeated in time or space to validate efficacy of practices. Results of trials will be disseminated at field days, extension trainings, and through written material.

Outputs
Target Audience:The target audience was farmers, Extension Agents, academic/government agriculture researchers, agroindustry representatives, and any other agricultural workers. In particular, people involved with agronomic and horticulture food and fiber annual crop production were the primary target audience. Changes/Problems:As with most research labs, COVID restrictions limited output during the final reporting period of this project. As much as possible, we tried to adapt to circumstances to remain productive. i.e., Working on publications at home when not allowed to conduct research in the field or lab. However, personal childcare responsibilities limited productivity. UF lifted field research restrictions in time to complete most of our field research season. What opportunities for training and professional development has the project provided?This project provided opportunities for 3 graduate students and one post-doctoral researcher to be involved in the studies described above, given them valuable experience in applied plant nematology. How have the results been disseminated to communities of interest?Results have been disseminated to communities of interest through the listed publications, presentations and involvement in Extension events (seminars, field days, Extension Agent trainings), and newsletter articles. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Investigated use of conventional and alternative crop rotations for reniform nematode management Investigated integration of nematicide application with crop rotation for nematode management Investigated impacts on agricultural management practices on soil ecology based on free-living nematodes
