Make The Right Call. Spray A Fungicide.
You want what’s best for your farm. And, sometimes, that means you have to get the job done and done early.
The best way to get rid of sclerotinia is to spray a fungicide before you even see it. Because once it’s found, it’s already too late. To get the highest level of disease control, a fungicide such as Proline® should be applied well before you spot the disease in your crop.
Just because you can’t see it, doesn’t mean it isn’t there

What can you do?
- Rotate your crops, as sclerotinia only affects broadleaf crops and weeds
- Consider disease pressure from last year and your seed variety for the upcoming year to further assess your risk of an outbreak
- Scout your fields as often as you can
- Spray a fungicide before the disease shows itself to maximize disease control – if sclerotinia is found, it can already be too late.
What do you need to know?
- Sclerotinia can overwinter in the soil for up to five years and can rotate back into your crop
- Sclerotinia spores can travel up to 1 km from their original position
There are other tools and resources available to help assess the sclerotinia risk potential in your canola crop:
- Petal test kits and in-field diagnostic kits are available from your local retailer or agronomist
- A checklist or Risk Assessment Tool, which helps you assess the sclerotinia risk potential in your area.
- Or use the Sclerotinia Spraying Decision Guide to help make your decision easier.
Once your level of risk has been identified, the ROI Calculator will help you calculate your possible return on investment based on your decision to spray.
