Estimation of the risk of sclerotinia stem rot development is based on temperature and precipitation patterns prevalent in the region as recorded by NDAWN stations. Areas where conditions are favorable for infection are presented in red; If apothecia are prsent in these fields fungicide applications may be warranted. Fields in yellow areas should be scouted for apothecia and changing weather conditions. Fields in green areas have low risk of disease development. The estimation of risk applies to canola fields that are in the flowering period only.
