BASF issues new call to action in weed management
Finally, growers can also select tank-mix partners with different sites of action when weather or workload prohibits more than one application during a season to maintain the benefits of a multi-site of action program.
Tip #4: Understand the big picture
Due to resistance, the big picture when it comes to weeds is changing for growers. No single strategy, including herbicide treatment, should be relied upon for weed management.
“BASF is working in the field to provide solutions, technical support and tools to help growers manage weeds based on herbicide best practices,” said Westberg. “One way BASF has done that is by providing the most corn and soybean herbicide sites of action of any crop protection company. But growers should also proactively plan for things like scouting, planning, and cultural and mechanical strategies.”
When scouting during the season, a grower needs to pay particular attention to fields that have escaped weeds. With this information growers can properly select herbicides and prioritize fields for a residual herbicide application the following year.
Growers can take out extra insurance by adhering to cultural and mechanical best practices for weed management. Strategies such as crop rotation, row spacing, planting dates and seed populations provide growers with additional cultural methods for reducing weed pressure. Tillage and cultivation, hand roguing before seeds set, and equipment sanitation between fields are mechanical strategies that also provide protection from yield loss by weeds.
