The Importance of Residual Herbicides
Residual herbicides are crucial for establishing effective weed control at planting. They need to be activated soon after application to prevent weed emergence, which can lead to increased competition for crops.
Recent Weather Impact
Arkansas has experienced a rapid transition from wet to dry conditions, complicating the activation of herbicides. This shift has raised concerns among farmers about the effectiveness of their weed control strategies.
Irrigation as a Solution
Irrigation can serve as an effective means to activate residual herbicides when rainfall is insufficient. Farmers are encouraged to consider irrigation options to ensure herbicides remain effective.

Questions & answers
Quick answers
What is the role of rainfall in herbicide activation?
Rainfall is essential for activating residual herbicides, as it helps dissolve the herbicide in the soil, making it available to germinating weed seedlings.
How can I ensure my herbicides remain effective during dry spells?
Consider using irrigation to activate residual herbicides if rainfall is insufficient after application.
What crops benefit from residual herbicides?
Crops such as cotton, corn, rice, and soybeans all benefit from the application of residual herbicides for effective weed control.
