With all the recent moisture comes higher disease pressure on crops.
Canola Council of Canada agronomy specialist Angela Brackenreed says, in particular, when it comes to sclerotinia in canola crops, the level of disease is almost directly associated with the moisture conditions just prior to and during flowering of the crop.
When it comes to fungicide application, many Manitoba fields have been to wet for equipment, but Brackenreed says it's easy to miss timing for sclerotinia, as it's a small window for application.
"It can only be four to five days after first flower that you'd hit 20 per cent bloom, which is that ideal timing for sclerotinia application, 20 to 30 per cent bloom," Brackenreed says. "It can happen really, really fast, so if you're not able to get onto the field, you can miss it."
Brackenreed says in order to be most economical, it's important to spray early. She says if a crop appears to have the yield potential and warrants an application, producers may want to look into aerial applications.
