With the excess rain in recent weeks, canola is at risk for sclerotinia or white mold. In the Pioneer Agronomy Update, Field Agronomist Kristie Sundeen said the best time for a fungicide application is 20-to-50 percent bloom stage. “Twenty percent bloom is when there’s 14-to-16 flowers are open on the main stem,” said Sundeen. “Fifty percent bloom is when the canola is at its most yellow and the main stem will have 20-plus flowers and developing pods on the main stem.” The Sclerotinia Risk Map is online.
