·31 min·3 clips

Bob Scott reveals the full scope of weed control in rice, from burndown to post-flood strategies.

This episode focuses on weed control programs for rice production in Arkansas, addressing current agronomic challenges. Host Bob Scott, an Extension Weed Specialist, is joined by co-host Dr. Jason Norsworthy, a Distinguished Professor, and guest Dr. Jared Harkey, an Extension Rice Agronomist. The discussion covers strategies from pre-plant through post-flood applications, acknowledging reported seed availability issues and variable rainfall conditions across the state. The hosts plan to examine differences between production systems like row rice versus flooded rice. They will compare various herbicide-resistant rice systems, including Clearfield, FullPage, Provisia, and the Max Ace with High Cart systems against conventional options. The conversation stems from recent grower phone calls concerning excessive, insufficient, or optimal rainfall and its implications. Dr. Harkey provides his expertise on these agronomic issues and their interaction with weed management. A key insight is the integrated approach linking water management, planting timing, and herbicide selection for effective control. The discussion highlights how specific production systems, such as row rice, necessitate distinct weed control strategies compared to permanently flooded fields. The variety of available herbicide systems presents growers with multiple tactical options, each with different considerations. The experts frame weed control as a season-long program rather than a single application. The tone is professional, educational, and conversational, aimed at providing practical recommendations. The style is direct and informational, reflecting an Extension service mission to disseminate research-based guidance. Farmers, crop consultants, and agronomists managing rice in Arkansas or similar environments would find this episode highly relevant. Listeners seeking broad, non-technical agricultural content or those outside of rice-producing regions might choose to skip it.
