Source summary
What this podcast covered
Current Pest Pressures
Rice fields are experiencing a range of stink bug infestations, with some reports indicating numbers as high as 50 per head. Growers are advised to treat fields with higher populations to prevent yield loss.
Armyworm Concerns
While armyworms have not been widely reported in rice, they are appearing in bean fields. Early detection and treatment are essential to manage these pests effectively.
Spider Mite Management
Spider mites are becoming more prevalent, particularly in Northeast Arkansas. The use of abamectin has shown promise, but growers must allow time for the product to take effect before reapplying.
Weather Considerations
With scattered showers expected, the timing of insecticide applications is critical. Growers should consider using adjuvants to improve rain fastness and protect their treatments.
Scouting and Treatment Strategies
Regular scouting is essential as pest populations can change rapidly. Growers should be prepared to adjust their management strategies based on the latest observations and pest dynamics.

Questions & answers
Quick answers
What should I do if I find high numbers of stink bugs in my rice?
If you find stink bug populations above 12 per head during flowering, it's advisable to treat those fields to prevent yield loss.
How can I manage armyworms in my bean fields?
Monitor your bean fields closely for armyworms and be prepared to treat if populations increase significantly.
What insecticides are effective against spider mites?
Abamectin has shown effectiveness against spider mites, but it requires time to work, so be patient before reapplying.
How does weather affect my insecticide applications?
Scattered showers can impact the effectiveness of insecticides, so consider using adjuvants to improve rain fastness.
Why is scouting important during this time of year?
Regular scouting helps identify pest pressures early, allowing for timely management decisions that can protect crop yields.
