Body

The crop disease management research program at the NDSU Carrington Research Extension Center is making a concerted effort to publish research findings and associated management recommendations online. Results and recommendations are presented as user-friendly PDF summaries that are easy to interpret and accompanying explanatory YouTube videos that can be accessed by anyone, from anywhere, at any time. They can be accessed at https://www.ndsu.edu/agriculture/ag-hub/research-extension-centers-recs/carrington-rec/research/plant-pathology or by searching online for ‘NDSU Carrington plant pathology’.

Available online at this time are research results and associated recommendations for (1) optimizing management of white mold management in dry beans, Ascochyta blight in chickpeas, and powdery mildew in field peas with fungicides; (2) comparative fungicide efficacy for management of white mold in soybeans; and (3) optimizing the integrated use of planting date, variety selection, fungicide seed treatment and crop rotation for achieving satisfactory field pea agronomic performance under Aphanomyces and Fusarium root rot pressure.

This June, every effort will be made to publish the following research results and associated recommendations for improved white mold management in soybeans: (1) optimizing fungicide droplet size relative to canopy characteristics, (2) response to fungicide spray volume, (3) impact of spray conditions on fungicide performance, and (4) optimizing fungicide application timing when conditions favor white mold as soybeans enter bloom.

During the 2025-26 winter season, this web page will be updated with results from the 2025 growing season. Additional research results and recommendations will also be posted for other crops and diseases and for additional management strategies for white mold in dry beans.
