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.
June 11, 2018 By Top Crop Manager
- 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?
