What this podcast covered
Emerging Herbicide Strategies
The podcast emphasizes the potential of Prowl and Bolero as effective herbicides for controlling barnyard grass and flat sedge in Arkansas rice. These products are noted for their residual effectiveness, especially when applied at the right time.
Importance of Application Timing
Timing is highlighted as a crucial factor in weed management, particularly for late-emerging weeds like flat sedge. Experts recommend adjusting application schedules to ensure herbicides are effective when weeds are most vulnerable.
Resistance Management
The discussion reveals a concerning trend of increasing resistance among barnyard grass populations to commonly used herbicides like NuPath. This underscores the need for farmers to adopt integrated weed management practices to mitigate resistance issues.
Future of Rice Production
As Arkansas rice farmers navigate these challenges, the insights shared in the podcast could lead to more effective weed management strategies. Adapting to these changes is vital for sustaining rice production in the Delta region.

Questions & answers
Quick answers
What are the best herbicides for controlling barnyard grass in rice?
Prowl and Bolero are recommended as effective options for managing barnyard grass in Arkansas rice.
How does timing affect herbicide effectiveness?
Applying herbicides at the right time, especially before late-emerging weeds appear, is crucial for maximizing control.
What is the current resistance situation for barnyard grass?
Over 50% of barnyard grass samples in Arkansas are resistant to NuPath, highlighting the need for alternative strategies.
Can mixing herbicides improve weed control?
Yes, mixing different herbicides can enhance effectiveness and reduce the risk of resistance development.
