Management of powdery mildew in field peas

Successful management of powdery mildew of field peas requires either selection of a resistant field pea variety or a preventative application of an effective fungicide at the appropriate timing.  Research conducted by NDSU indicates that registered fungicides differ sharply in their efficacy against powdery mildew and that a single application of the most effective fungicides applied when peas are in full bloom with the first pods full and full-length and partially to fully filled can confer season-long management of this disease.

Management of Ascochtya blight in chickpeas

Successful management of Ascochyta blight of chickpeas requires early, preventative applications of the most effective fungicides, and research conducted by NDSU indicates that fungicide performance against Ascochyta blight can be improved by optimizing fungicide droplet size relative to chickpea canopy characteristics.

Optimizing the management of white mold in dry beans with fungicides

Multi-year,  multi-location research conducted by NDSU indicates that the management of white mold in dry beans can be improved through (1) choice of fungicide, (2) optimizing fungicide spray droplet size relative to canopy characteristics, (3) optimizing fungicide application timing, and (4) optimizing fungicide application frequency and interval.  Fungicide application timing, application interval, and application frequency are more important determinants of fungicide performance than spray volume.

Optimizing the management of white mold in soybeans with fungicides

Multi-year, multi-location research conducted by NDSU indicates that the management of white mold in soybeans can be sharply improved through (1) choice of fungicide, (2) optimizing fungicide spray droplet size relative to canopy closure, and (3) optimizing fungicide application timing.

Improving management of Aphanomyces and Fusarium root rot in field peas

Multi-year, multi-location research conducted by NDSU indicates that losses to Aphanomyces and Fusarium root rot in field peas can be sharply reduced through the integrated use of planting date, fungicide seed treatment, crop rotation, and field pea variety selection.  Each of these management tools confers partial management of this root disease complex, and excellent management of Aphanomyces and Fusarium root rot has been achieved by integrating these strategies.  Posted below are updates on our ongoing research on optimizing these strategies for improved field pea agronomic performance under Aphanomyces and Fusarium pressure.
