The Rise of Ryegrass Resistance
Ryegrass has become a significant concern for Arkansas farmers, with its resistance spreading northward. Experts emphasize that proactive management is essential to prevent severe infestations.
Importance of Fall Herbicide Applications
Applying residual herbicides in the fall can help manage ryegrass before it establishes itself. This strategy is becoming increasingly important as farmers face limited options in the spring.
Cost Implications for Farmers
The discussion highlights the financial burden of managing established ryegrass in the spring. By investing in fall applications, farmers can potentially save on higher control costs later.
