Proper staging is critical when applying in-crop herbicides in corn, but there are multiple ways to measure corn’s growth stages, and herbicide labels don’t always use the same method. Agronomists often use the “leaf collar” — or V-stage — method to describe growth stages, while others use plant height. However, herbicide labels often refer to… Read More

Dry spring planting conditions have many growers wondering how their soil-applied residual herbicides will perform, as the weather continues to heat up with little meaningful rain in sight. Research by University of Guelph weed scientist Dr. Peter Sikkema indicates pre-emergence herbicides will still deliver significant value for growers in dry spring conditions. He notes that… Read More

With winter wheat progressing rapidly through its growth stages in Ontario, RealAgriculture agronomist Peter Johnson is advising growers to keep a close eye on the crop. With crop development running 10 days ahead of schedule, Johnson says wheat fields need to be scouted to make critical management decisions to optimize yield. On this episode of… Read More
