Managing to Minimize Atrazine Runoff to Surface Water

---

Summary
Atrazine is used widely in Kansas for weed control in corn and grain sorghum. The herbicide provides cost-effective weed control and has wide application flexibility. In recent years there have been concerns about the levels of atrazine moving from corn and grain sorghum fields into surface waters. The highest levels of atrazine in surface water occur in the spring and summer months following herbicide application. The movement of atrazine from crop fields is determined by the chemical properties of atrazine; soil and site characteristics; tillage practices; application timing and methods; and rainfall duration, intensity, and timing. K-State researchers have studied the effect of various management practices on atrazine runoff and have determined those BMPs which, when adopted by farmers, will minimize atrazine runoff. The greatest reduction will be achieved by using a combination of BMPs. Farmers are encouraged to adopt the BMPs for their fields that are most economical and most effective in reducing atrazine runoff. Atrazine BMPs are designed to: (1) reduce the availability of atrazine for loss; (2) reduce the rate of atrazine used in a field/watershed; (3) reduce the impact of the first runoff event; and (4) provide a mechanism for deposition of the atrazine before it leaves the field.
