What are the atrazine application rate limits in Iowa?

The atrazine application rate limits in Iowa specify that 1.5 pounds per acre per year can be applied in certain counties designated as having vulnerable groundwater. This regulation is crucial for protecting water resources from contamination since atrazine is a herbicide that can leach into groundwater. The 1.5 pounds per acre cap ensures that the use of atrazine is managed carefully in areas where there is a higher risk of groundwater contamination, thereby promoting environmental safety and public health.

Other application rates may apply in different contexts or locations, but they do not pertain specifically to the regulated counties that have been identified for this limit. Understanding these limits is essential for pesticide applicators to ensure compliance with state regulations and to promote sustainable agricultural practices.
