Sclerotinia Risk in Canola
This forecasting program has been developed by the North Dakota State University Canola Pathology program with support from the Sclerotinia Initiative, the Northern Canola Growers Association, and the Minnesota Canola Council. While the information presented by this program is based on data generated through extensive research, it is only intended to serve as a guide for growers.
This forecasting program has two components, a general risk map and a risk calculator. The general risk map uses weather information to estimate risk of disease development throughout the canola growing areas of the state. This map is updated twice every week starting in mid June and continuing during the canola flowering period. The risk calculator combines information on cultural practices and the field past history of Sclerotinia with weather information retrieved from the nearest NDAWN weather station to estimate the risk of disease development for a specific field. To access the risk calculator visitors are asked to set an account and to provide information pertinent to the field of their interest.
News and Tips for You
July 19, 2009
Environmental conditions have been on the dry side (absence of rain and rather low relative humidity) in most canola growing areas of the state during the past four days. These conditions are not favorable for disease development, and that is reflected in the map produced for July 19th. The risk of Sclerotinia is now low for all areas of the state.
Also, enough canola-growing degree days have accumulated since last week so that most canola fields are now ending their flowering period. Such fields do not need spraying. Growers with fields still in early stages of flowering should look for presence of apothecia and should watch the weather conditions this week.
