 With a Pioneer agronomy update, here's Pioneer field agronomist Christy Sundeen. The weather continues to create challenges for growers this year. Excess rainfall has hampered spraying for many, and the lack of heat has slowed row crop growth. Early canola is also in bloom, and with the excess rainfall, the risk for white mold is high. We are about 160 to 200 GDUs behind the five-year average, but only 50 to 100 GDUs behind normal.
