Does it make sense to apply fungicide to protect against blackleg?
Whether or not to use fungicide at the same time as herbicide to protect from blackleg infection depends on a number of factors. The most recent disease update from Manitoba Agriculture includes questions growers should ask themselves when it comes to protecting their crop.

- What is your rotation? A field with tight rotation (two years or less) is also higher risk for blackleg infection
- Have you seen yield loss from blackleg in the past?
- Has the environment been conducive for infection? The release of ascospores from overwintering bodies is favoured following a rainfall and when temperatures range from 16 to 20°c.
- Is your crop worth it? How bad is the insect damage, do you want to be investing more money in this particular field?
