Validation of a Disease-warning Model for Sclerotinia Stem Rot of Canola for the North Central Region

Validation of a Disease-warning Model for Sclerotinia Stem Rot of Canola for the North Central Region
Luis del Río-Mendoza, North Dakota State University - $10,000

Sclerotinia stem rot of canola (SSR) is one of the most important diseases affecting canola production in North Dakota. Current disease management practices are limited to crop rotation and fungicide applications, since genetic resistance to this disease is not commercially available.

A disease-warning model developed two years ago could not be validated in the past due to unfavorable weather conditions that limited SSR epidemic development. Validation of the model would result in more accurate outcomes in the future, which in turn will help growers make better informed decisions regarding disease control measures.

Fungicide use is, in the absence of resistant cultivars, the ultimate resource growers have. Accurate predictions could help optimize fungicide usage increasing in this way the profitability of the production operation and reducing environmental pollution.

Objective:
1. Validate the outcome of a disease-warning model for Sclerotinia stem rot of canola.
