Source summary
What this podcast covered
Stink Bug Management
The rise in stink bug populations, particularly nymphs in rice, necessitates careful monitoring and timely insecticide applications. Farmers are advised to consider thresholds when deciding on treatments to avoid crop damage.
Cotton Crop Status
As cotton approaches the end of its effective bloom period, pest management strategies are shifting. The focus is on terminating trials and managing remaining pests effectively before the season concludes.
Soybean Pest Dynamics
In soybeans, the presence of both green and brown stink bugs complicates management decisions. Farmers need to adjust their insecticide choices based on the specific types and numbers of stink bugs present.
Emerging Defoliators
Salt marsh caterpillars have been reported, but their impact is currently manageable. Treatment should only be considered if defoliation reaches significant levels, as they are not as threatening as other pests.
Loopers and Other Pests
Loopers are lingering in fields but not increasing significantly. Farmers should remain vigilant but may not need immediate action unless populations rise dramatically.

Questions & answers
Quick answers
What should I do if I find stink bugs in my rice?
Monitor the population closely and apply insecticides if nymph levels exceed thresholds.
How do I know when to terminate my cotton crop?
Termination is typically advised after the last effective bloom date, which varies by region.
What insecticides are recommended for managing stink bugs in soybeans?
Lambda is effective for lower numbers of green stink bugs, while bifenthrin or acephate may be needed for higher populations.
Are salt marsh caterpillars a significant threat to my crops?
They are generally manageable but should be treated if defoliation becomes noticeable.
What are the current conditions for loopers in my fields?
Loopers are present but not increasing significantly; monitor them but immediate action may not be necessary.
