What this podcast covered
Understanding Glyphosate Resistance
Glyphosate-resistant ryegrass is becoming a significant issue for farmers, particularly in Arkansas. Experts recommend assuming that most ryegrass populations are resistant, which necessitates a shift in management strategies.
Effective Burndown Strategies
For effective burndown, paraquat combined with PS2 inhibitors is preferred over clethodim for larger ryegrass plants. This approach allows for quicker action and reduces the risk of crop failure due to delayed planting.
Importance of Plant-Back Intervals
Farmers must be aware of the plant-back intervals associated with different herbicides. Using select herbicides can lead to a month-long wait before planting, which can disrupt planting schedules.
Mixing Herbicides Cautiously
Mixing herbicides can lead to reduced efficacy, especially when combining systemic and contact herbicides. Careful consideration of tank mixtures is essential for effective weed control.
Proactive Management Recommendations
To prevent ryegrass from seeding, proactive management practices are necessary. Farmers are encouraged to monitor fields closely and adjust their herbicide strategies accordingly.

Questions & answers
Quick answers
What is the best herbicide for managing ryegrass this spring?
Experts recommend using paraquat combined with PS2 inhibitors for effective control of larger ryegrass plants.
How long should I wait to plant after using select herbicides?
There is a plant-back interval of about a month after using select herbicides, which can delay planting.
What should I do if I suspect glyphosate resistance in my fields?
Assume that most ryegrass is glyphosate resistant and adjust your management strategies accordingly.
Can I mix different herbicides for better results?
Mixing herbicides requires caution as it can reduce efficacy; avoid combining systemic and contact herbicides.
What proactive steps can I take to manage ryegrass?
Monitor fields closely and implement effective weed management strategies to prevent ryegrass from seeding.
