Innovative Approaches to Weed Management
Farmers are exploring new methods for weed control, particularly with Zidua applied through fertilizer, which has shown effectiveness against resistant pigweed populations. This approach is gaining popularity as traditional methods struggle to keep pace with resistance issues.
Challenges with Grass Control
Grass species, particularly goosegrass, continue to pose significant challenges for Arkansas farmers. The discussion highlights the need for careful management of herbicide applications to avoid antagonism that can reduce control effectiveness.
Importance of Residual Herbicides
As the growing season progresses, the application of residual herbicides becomes increasingly important to manage weed pressure effectively. Farmers are encouraged to integrate these strategies into their mid-season management plans.

Questions & answers
Quick answers
What is Zidua and how is it used for weed control?
Zidua is a herbicide that can be applied via fertilizer to control pigweed, showing effectiveness in recent trials.
Why are dicamba and 2,4-D less effective against pigweed?
These herbicides are struggling to control pigweed due to increasing resistance levels in the population.
What challenges do farmers face with grass control?
Farmers are experiencing difficulties with grass species like goosegrass, especially under dry conditions that exacerbate control issues.
How can farmers improve their weed control strategies?
Separating glyphosate and dicamba applications can enhance control effectiveness, and using residual herbicides is crucial as the season progresses.
What should farmers consider for mid-season weed management?
Farmers should focus on applying residual herbicides and innovative strategies like Zidua to manage emerging weed pressures effectively.
